Hollywood works hard to produce great movies, there’s no doubt about that. Plenty of industry professionals are working around the clock, 7 days per week, to provide top-shelf entertainment to the masses. And while (most) studios try their best to depict military tactics as accurately as possible, they often fall short. One area in particular where they always seem to get things wrong is urban combat — specifically, the most fundamental component: clearing buildings.
Now, don’t get us wrong — there are plenty of movies that nail it perfectly (typically the ones with a good military adviser, hint hint) but we’ve seen plenty of mistakes make it all the way to the silver screen. After all, there’s a reason I’m writing this article.
Here are some of the most basic rules that get broken consistently in movies.
If you’ve got someone watching your back, no worries.

Never enter a room alone
It’s the cardinal rule of military operations in urban terrain (or, MOUT): You should never, under any circumstances, enter a room by yourself. At minimum, you need to bring one other person with you. If you enter a room alone, you could get cut down by an enemy and there’d be nobody to back you up.
Time and time again, we’ll see brazen heroes kick down doors solo — even when they’ve got teammates available.
Drop your gun, enemy drops you.

Keep your gun up
Keep your gun up; keep your guard up. If a building hasn’t been cleared yet (we’ll get to that in a minute), your gun should remain ready to go. If you drop it in an unclear house, you could be caught off guard at the wrong moment — and it could mean the end of you.
We can’t tell you how many times we’ve seen characters walk through houses with their muzzles pointed at the dirt.
You better yell like someone’s life depends on it.
Everything you see, everything you hear, and everything in between needs to be communicated or repeated. No one can see every space of the room, so it’s your job to tell everyone else what you see. This way, if you find enemies, everyone in your unit knows immediately.
We’ve seen plenty of shows and movies that feature silent warriors that rely on hand signals. In fact, one of the only times we’ve seen it done right was in Sons of Anarchy. In the second episode of the third season, the Sons close in on the location of the leader of a rival gang. As they move through the house, they communicate every little thing loudly and clearly. Leave it to the lawless to abide by the rules of war.
Make sure to maintain muzzle awareness as well.

Move your muzzle with your eyes
If you turn your head, your gun goes with it. If your gun isn’t locked with your eyes, you’ll need an extra second to get it there if things go south. Needless to say, your enemy doesn’t want to give you that extra second.
Characters in movies are always looking around without their gun, even when the character is supposed to be some Special Ops badass.
You never know when an enemy is hiding in a corner or under a table.

Check every space
A building can only be declared “clear” when every space has been observed. If a building has a basement, attic, or both — you better check ’em. Drawers, cabinets, closets, shelves, holes in the walls — it all gets inspected. If it doesn’t, that one drawer you decided was okay could have a f*cking bomb in it.
Funnily enough, in movies, when a character doesn’t follow this rule, they’ll often been made an example for the rest of the squad.
1. Not keeping your kitchen stocked can lead to disorganization and last-minute shopping trips.
The first rule of meal prep is to keep your kitchen stocked with the essentials, especially when it comes to ingredients with a longer shelf life.
Registered dietitian Becky Kerkenbush said a kitchen ready for meal prep will have staple ingredients like rice, oats, frozen fruit, frozen or canned vegetables, cooking spray and oil, frozen protein (chicken, fish, etc.), herbs, spices, and canned legumes and beans.
2. Insisting on prepping all of your meals only once per week might be too stressful or impractical.
Although it’s nice to be able to knock out all of your meals in one go, don’t be afraid to prep more than once per week if it suits your lifestyle better.
Kerkenbush told INSIDER that for tastier meals and possibly better food-safety practices, a good rule of thumb is to aim for prepping twice a week.
And if the idea of prepping multiple times per week seems a bit overwhelming, consider starting slow.
Monica Auslander Moreno, registered dietitian and nutrition consultant for RSP Nutrition, said if it feels like you’re committing too much too soon, consider taking on one breakfast, one lunch, or one dinner at a time.
“Don’t try to launch a full week’s worth of meals at once, that’s very stressful. Instead, build your repertoire as you go,” she told INSIDER.
3. Not storing food properly could lead to wasted or spoiled meals.
Aluminum foil and plastic wrap may not be the best tools for meal prepping.
To keep food fresh and properly portioned, Kerkenbush said you should store meals in individual containers that have a tight seal. It’s also useful to label and date your prepared containers before putting them in the fridge or freezer.
4. Preparing more food than you need might lead to waste and stress.
If you’re not feeding a large group, you likely don’t need to create dozens of meals in advance, especially if your prep time is limited.
“Make as much food as you’re comfortable with and that you really need to help minimize stress and food waste,” Toby Amidor, registered dietitian and author of “The Healthy Meal Prep Cookbook” and ” Smart Meal Prep for Beginners,” told INSIDER.
When deciding how many meals to prepare each week, also consider whether or not you might tire of a dish after eating it multiple days in a row and plan ahead for any upcoming trips or social engagements that won’t require you to bring ready-made dishes.
6. By not freezing extras, you’re missing out on bonus meals.
Although the containers stacked high in your fridge may not look like a lot of food, there’s a chance you may end up with more meals than you can eat in a week, especially with heartier dishes like lasagna or slow-cooker chili.
“This is the perfect time to freeze individual-sized containers so you can have a delicious dish ready when you are busy down the road,” said Amidor.
In the days before naval aviation and submarines, the battleship was the unchallenged king of the seas. Building a bigger and better ship with more and bigger guns was basically the order of the day, and it continued all the way up until the days before World War II, when the world reached peak battleship, and airplanes proved to be deadlier than the Navy ever imagined.
But America almost reached peak battleship before World War I was even a possibility, and it was possibly the biggest battleship ever conceived – it also might have been an ironic joke from someone who hated the Navy.
Benjamin Tillman, famous racist and Navy hater.
Benjamin Tillman was a U.S. Senator from South Carolina and a member of the Senate Naval Affairs Committee. He was annoyed at the Navy for coming to Congress every year to request money to build more and bigger battleships. Despite this pretty much being what the Navy is supposed to do, Tillman decided it would be best to just get the whole arms race out of the way and build the biggest possible battleship they could at the moment. This led to the creation of the Maximum Battleship design.
No, that’s really what they called it.
Tillman hated the Navy’s battleships, and everyone knew it, but when he requested the Department of the Navy just submit the plans for the biggest battleship they could, the Navy obliged him anyway. There were, however, restrictions on U.S. ship designs at the time. Namely, they had to fit through the Panama Canal.
The first design submitted was a massive 70,000 tons – almost 50 percent heavier than the modern Navy’s USS Missouri – and this was in 1916. It carried 12 16-inch guns and had an armor thickness of 18 inches. In comparison, the Iowa-class battleships of World War II would carry just nine 16-inch guns and have a maximum armor thickness of 14.5 inches. The next iteration of Maximum Battleship designs would have 24 16-inch guns and an armor thickness of 13 inches. It was the third design that really took the cake, however.
Maximum Battleship III – also known as the Tillman III design – weighed 63,000 tons. It had the armor of the second design and the guns of the second design. It could even move at an absurd 30 knots, which is almost as fast as an Iowa-class ship and an insane speed for a ship of that size in 1916. This is a weight equal to the largest battleships ever actually built that moves even faster and was supposed to be built 20 years earlier. That wasn’t the end of the attempt, though. There would be another.
The largest of the Tillman Designs.
The fourth design for Tillman featured the 24 guns and even thicker armor, coming in at 19 inches. It was clear by now the Navy wasn’t expecting to get funding for these. The fourth design would displace 80,000 tons and was practically impossible to build with the technology of the day. In all, six designs were made, each bigger and more ridiculous than the last. It would be as big as the modern American supercarriers and carry the most and biggest weapons of anything on earth, on land, or on the oceans. And it would have been sunk just as easily with the advent of naval aviation.

Although some of our favorite films are pretty “out there” when it comes to pulling off some amazing feats, there are quite a few movie moments that Marines would love to train their asses off for and totally pull off.
In a hostage situation, shooting around the victim and nailing the assailant would come in quite handy — if we could master it. But we doubt we ever could.
How awesome would this be?
2. Shooting out the floor (Underworld)
In many cases, service members have to find clever ways to evacuate from a desperate situation. In 2003’s Underworld, Selene (played by Kate Beckinsale) shoots the floor out in order to escape from vicious werewolves.
This is a great idea; you know, if the physics were possible and humans could handle 20-foot drops.
If it worked for her, it should work in real life.
3. Inverting you fighter jet (Top Gun)
When flying in an aerial dogfight, there’s no better way to send the enemy an FU message like Maverick’s in 1986’s Top Gun. He managed to fly inverted and flip the bird to his rival flying ace.
This feat is near impossible, but “Mav” makes it look easy as hell.
They went ballistic!
4. Putting on a parachute in mid-air (Eraser)
In 1996, director Chick Russell took on a stunt that had audience asking, “How did they do that?” when U.S. Marshal John “The Eraser” Kruger threw a parachute outside of a speeding plane at high-attitude then retrieves the “chute” in mid-air.
We think that’s pretty badass.
Who wants to go skydiving?
5. The backbend bullet dodge (The Matrix)
At times, Marines fight in close quarters combat when charging in enemy territory, and, unfortunately, sometimes they get shot. Wouldn’t it be awesome if they could just dodge incoming rounds like Nero? We think so.
6. Shooting someone through their scope (Saving Private Ryan)
Steven Spielberg knows how to tell an effective story, and he did just that directing 1998’s critically-acclaimed Saving Private Ryan.
After showing the world how American troops stormed the beaches of Normandy, he brilliantly captured the moment when Pvt. Jackson (played by Barry Pepper) takes out a German sniper with a perfectly aimed round right through his scope.
Although it’s reported Marine legend Carlos Hathcock made this historic shot, the myth has been both deemed both “busted” and “plausible” by the same people — the Myth Busters. Regardless, we want to be able to pull it off again, and again. Mostly for bragging rights.
After her heroics on the front lines of the Korean War, Lt. Gen. Randolph Pate promoted Reckless to sergeant. Reckless was transported to the U.S. where she became a Marine Corps celebrity, gave birth to four children, and was promoted to staff sergeant before retiring to Camp Pendleton.
Over the course of her career, Reckless received two Purple Hearts, a Good Conduct Medal, the Presidential Unit Citation with star, the National Defense Service Medal, the Korean Service Medal, and the United Nations Service Medal.
Since her death, Reckless has been honored with a memorial at the Camp Pendleton stables, a Dickin Medal for animal bravery, and now a statue at Camp Pendleton.
U.S. Army vet Gregory Wong is no stranger to making fan films. His Jurassic World fan filmsand their behind-the-scenes extras have 2 million+ views on YouTube alone thanks to the military perspective he and his teams brought to the franchise.
An avid airsofter and gamer, Wong enjoys bringing those tactics to life after his military service.
Most recently, he teamed up with some fellow veterans and civilians to create a one-shot style video that emulates the experience from the new Call of Duty game.
Check it out right here:
CALL OF DUTY IN REAL LIFE | CLEAN HOUSE MODERN WARFARE – SIONYX
“Since everyone, both civilian and military, has been sinking their time into the game, it felt like a fun opportunity to explore and experiment by emulating the most talked about portion,” shared Wong.
The video also uses a color night vision camera built for outdoor use — and a little help from post-production.
“We used editing software to give it that iconic green look,” Wong divulged. “It’s a good exercise for making fan projects with limited budget but high attention to detail. We were fortunate to have gear from one of the companies that actually supplies the CTSFO (British national police force like FBI SWAT or FBI HRT).”
Wong’s team used the Aurora, a day/night camera with true night vision that uses Ultra Low-Light IR sensor technology that delivers true night vision capability in monochrome or in color. They also shot with gear from c2rfast, Airsoft Extreme, and PTS Syndicate.
The Clean House mission in Call of Duty: Modern Warfare takes place in a large house that the player must infiltrate, eliminating enemies and protecting hostages. Forbes magazine called it the “finest single-player FPS experience in years.”
The head of NATO has demanded that Russia release Ukrainian sailors and naval vessels it seized in a confrontation at sea, while Russian President Vladimir Putin’s spokesman says concerns that Moscow could seek to create a “land corridor” linking Russia to Crimea are “absurd.”
NATO Secretary-General Jens Stoltenberg and Kremlin spokesman Dmitry Peskov spoke on December 3 as Russia continued to hold the 24 Ukrainian seamen in Moscow jails on border-violation charges Kyiv rejects.
NATO chief warns Russia over Crimea incident after chairing emergency talks
“Russia recently seized Ukrainian ships and sailors near the Kerch Strait. There is no justification for this use of force. We call for calm and restraint. Russia must release the Ukrainian sailors and ships,” Stoltenberg said on the eve of a two-day meeting of NATO foreign ministers who will address that issue, among others.
Russia, he said, “must also allow freedom of navigation and unhindered access to Ukrainian ports in the Sea of Azov. Ukrainian vessels — military as well as civilian — have the right to navigate through the Kerch Strait and the Sea of Azov.”
Russia has been holding the sailors — crewmen from three Ukrainian naval craft — since the confrontation on November 25 in which Russian Coast Guard ships rammed a Ukrainian Navy tugboat and fired on the boats before special forces boarded them.
The clash has added to tension over Crimea, which Russia occupied and took over from Ukraine in March 2014, and raised fears of a flare-up in a simmering war between Kyiv and Russia-backed separatists that has killed more than 10,300 people in eastern Ukraine since April 2014.
The Russia-backed separatists hold parts of the Luhansk and Donetsk regions, including a piece of shoreline that lies between the Russian border and the Ukrainian Sea of Azov port city of Mariupol.
Peskov dismissed concerns that Russia could seek to gain access by land to Crimea by seizing or helping the separatists to seize territory on the Azov shore from Mariupol to the isthmus further west that links the Ukrainian mainland to Crimea.
“It’s an absolutely absurd claim. It is another attempt to generate tension. Regretfully, attempts like this will most likely continue as we approach” the Ukrainian presidential election scheduled for March 31, he said.
Peskov claimed that “Russia has never invaded anything or created any corridors anywhere.”
But in addition to occupying and taking over Crimea, Kyiv, NATO, and Western governments say there is ample evidence that Russia has given the separatists in eastern Ukraine major military support in the war.
Meanwhile, a lawyer for one of the Ukrainian sailors confirmed on December 3 that all 24 had been charged by Russian authorities with “illegal border crossing.”
Nikolai Polozov, who is representing Denys Hrytsenko, said the sailors were formally charged on November 27.
Dzhemil Temishev, an attorney for another of the sailors, said on November 29 that 21 of the detainees were being transferred from Russia-annexed Crimea to the Lefortovo detention center in Moscow.
Russian authorities say three other Ukrainian sailors wounded on November 25 were receiving medical treatment at a different, unspecified detention center.
Russian Human Rights Commissioner Tatyana Moskalkova said on December 3 that the detained Ukrainian sailors had food, “clothes, and all the necessities.”
In remarks that appeared aimed to portray the jailing of the sailors as a strictly legal issue and tell the world that they were not being mistreated, Moskalkova said on state-run Rossia-24 TV that rights monitors “have visited the sailors and spoken with every one of them.”
She said the sailors “have no complaints about custody conditions or medical aid” and that lawyers had access to their clients. Her comments could not be independently verified.
The incident has raised tensions between Kyiv and Moscow to their highest point since Moscow seized Crimea.
Ukraine imposed martial law for 30 days in 10 regions, including all of those that border Russia or have coastlines on the Black Sea or the Sea of Azov.
Russia and Ukraine blame each other for the altercation. Russia closed the Kerch Strait to all sea traffic during the incident, and Kyiv says Russia has continued to deny passage to Ukrainian commercial traffic in and out of Mariupol and Berdyansk, another port on the Sea of Azov.
Western leaders — including all members of the G7 leading industrialized states — have called on Russia to release the Ukrainian crew and return the seized navy ships to Kyiv.
Just as dust gathers in corners and along bookshelves in our homes, dust piles up in space too. But when the dust settles in the solar system, it’s often in rings. Several dust rings circle the Sun. The rings trace the orbits of planets, whose gravity tugs dust into place around the Sun, as it drifts by on its way to the center of the solar system.
The dust consists of crushed-up remains from the formation of the solar system, some 4.6 billion years ago — rubble from asteroid collisions or crumbs from blazing comets. Dust is dispersed throughout the entire solar system, but it collects at grainy rings overlying the orbits of Earth and Venus, rings that can be seen with telescopes on Earth. By studying this dust — what it’s made of, where it comes from, and how it moves through space — scientists seek clues to understanding the birth of planets and the composition of all that we see in the solar system.
Two recent studies report new discoveries of dust rings in the inner solar system. One study uses NASA data to outline evidence for a dust ring around the Sun at Mercury’s orbit. A second study from NASA identifies the likely source of the dust ring at Venus’ orbit: a group of never-before-detected asteroids co-orbiting with the planet.
“It’s not every day you get to discover something new in the inner solar system,” said Marc Kuchner, an author on the Venus study and astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This is right in our neighborhood.”
In this illustration, several dust rings circle the Sun. These rings form when planets’ gravities tug dust grains into orbit around the Sun. Recently, scientists have detected a dust ring at Mercury’s orbit. Others hypothesize the source of Venus’ dust ring is a group of never-before-detected co-orbital asteroids.

Another ring around the Sun
Guillermo Stenborg and Russell Howard, both solar scientists at the Naval Research Laboratory in Washington, D.C., did not set out to find a dust ring. “We found it by chance,” Stenborg said, laughing. The scientists summarized their findings in a paper published in The Astrophysical Journal on Nov. 21, 2018.
They describe evidence of a fine haze of cosmic dust over Mercury’s orbit, forming a ring some 9.3 million miles wide. Mercury — 3,030 miles wide, just big enough for the continental United States to stretch across — wades through this vast dust trail as it circles the Sun.
Ironically, the two scientists stumbled upon the dust ring while searching for evidence of a dust-free region close to the Sun. At some distance from the Sun, according to a decades-old prediction, the star’s mighty heat should vaporize dust, sweeping clean an entire stretch of space. Knowing where this boundary is can tell scientists about the composition of the dust itself, and hint at how planets formed in the young solar system.
So far, no evidence has been found of dust-free space, but that’s partly because it would be difficult to detect from Earth. No matter how scientists look from Earth, all the dust in between us and the Sun gets in the way, tricking them into thinking perhaps space near the Sun is dustier than it really is.
Stenborg and Howard figured they could work around this problem by building a model based on pictures of interplanetary space from NASA’s STEREO satellite — short for Solar and Terrestrial Relations Observatory.
Scientists think planets start off as mere grains of dust. They emerge from giant disks of gas and dust that circle young stars. Gravity and other forces cause material within the disk to collide and coalesce.
(NASA’s Jet Propulsion Laboratory)
Ultimately, the two wanted to test their new model in preparation for NASA’s Parker Solar Probe, which is currently flying a highly elliptic orbit around the Sun, swinging closer and closer to the star over the next seven years. They wanted to apply their technique to the images Parker will send back to Earth and see how dust near the Sun behaves.
Scientists have never worked with data collected in this unexplored territory, so close to the Sun. Models like Stenborg and Howard’s provide crucial context for understanding Parker Solar Probe’s observations, as well as hinting at what kind of space environment the spacecraft will find itself in — sooty or sparkling clean.
Two kinds of light show up in STEREO images: light from the Sun’s blazing outer atmosphere — called the corona — and light reflected off all the dust floating through space. The sunlight reflected off this dust, which slowly orbits the Sun, is about 100 times brighter than coronal light.
“We’re not really dust people,” said Howard, who is also the lead scientist for the cameras on STEREO and Parker Solar Probe that take pictures of the corona. “The dust close to the Sun just shows up in our observations, and generally, we have thrown it away.” Solar scientists like Howard — who study solar activity for purposes such as forecasting imminent space weather, including giant explosions of solar material that the Sun can sometimes send our way — have spent years developing techniques to remove the effect of this dust. Only after removing light contamination from dust can they clearly see what the corona is doing.
The two scientists built their model as a tool for others to get rid of the pesky dust in STEREO — and eventually Parker Solar Probe — images, but the prediction of dust-free space lingered in the back of their minds. If they could devise a way of separating the two kinds of light and isolate the dust-shine, they could figure out how much dust was really there. Finding that all the light in an image came from the corona alone, for example, could indicate they’d found dust-free space at last.
Mercury’s dust ring was a lucky find, a side discovery Stenborg and Howard made while they were working on their model. When they used their new technique on the STEREO images, they noticed a pattern of enhanced brightness along Mercury’s orbit — more dust, that is — in the light they’d otherwise planned to discard.
“It wasn’t an isolated thing,” Howard said. “All around the Sun, regardless of the spacecraft’s position, we could see the same five percent increase in dust brightness, or density. That said something was there, and it’s something that extends all around the Sun.”
Scientists never considered that a ring might exist along Mercury’s orbit, which is maybe why it’s gone undetected until now, Stenborg said. “People thought that Mercury, unlike Earth or Venus, is too small and too close to the Sun to capture a dust ring,” he said. “They expected that the solar wind and magnetic forces from the Sun would blow any excess dust at Mercury’s orbit away.”
With an unexpected discovery and sensitive new tool under their belt, the researchers are still interested in the dust-free zone. As Parker Solar Probe continues its exploration of the corona, their model can help others reveal any other dust bunnies lurking near the Sun.
Asteroids hiding in Venus’ orbit
This isn’t the first time scientists have found a dust ring in the inner solar system. Twenty-five years ago, scientists discovered that Earth orbits the Sun within a giant ring of dust. Others uncovered a similar ring near Venus’ orbit, first using archival data from the German-American Helios space probes in 2007, and then confirming it in 2013, with STEREO data.
Since then, scientists determined the dust ring in Earth’s orbit comes largely from the asteroid belt, the vast, doughnut-shaped region between Mars and Jupiter where most of the solar system’s asteroids live. These rocky asteroids constantly crash against each other, sloughing dust that drifts deeper into the Sun’s gravity, unless Earth’s gravity pulls the dust aside, into our planet’s orbit.
At first, it seemed likely that Venus’ dust ring formed like Earth’s, from dust produced elsewhere in the solar system. But when Goddard astrophysicist Petr Pokorny modeled dust spiraling toward the Sun from the asteroid belt, his simulations produced a ring that matched observations of Earth’s ring — but not Venus’.
This discrepancy made him wonder if not the asteroid belt, where else does the dust in Venus’ orbit come from? After a series of simulations, Pokorny and his research partner Marc Kuchner hypothesized it comes from a group of never-before-detected asteroids that orbit the Sun alongside Venus. They published their work in The Astrophysical Journal Letters on March 12, 2019.
“I think the most exciting thing about this result is it suggests a new population of asteroids that probably holds clues to how the solar system formed,” Kuchner said. If Pokorny and Kuchner can observe them, this family of asteroids could shed light on Earth and Venus’ early histories. Viewed with the right tools, the asteroids could also unlock clues to the chemical diversity of the solar system.
Because it’s dispersed over a larger orbit, Venus’ dust ring is much larger than the newly detected ring at Mercury’s. About 16 million miles from top to bottom and 6 million miles wide, the ring is littered with dust whose largest grains are roughly the size of those in coarse sandpaper. It’s about 10 percent denser with dust than surrounding space. Still, it’s diffuse — pack all the dust in the ring together, and all you’d get is an asteroid two miles across.
Using a dozen different modeling tools to simulate how dust moves around the solar system, Pokorny modeled all the dust sources he could think of, looking for a simulated Venus ring that matched the observations. The list of all the sources he tried sounds like a roll call of all the rocky objects in the solar system: Main Belt asteroids, Oort Cloud comets, Halley-type comets, Jupiter-family comets, recent collisions in the asteroid belt.
“But none of them worked,” Kuchner said. “So, we started making up our own sources of dust.”
Perhaps, the two scientists thought, the dust came from asteroids much closer to Venus than the asteroid belt. There could be a group of asteroids co-orbiting the Sun with Venus — meaning they share Venus’ orbit, but stay far away from the planet, often on the other side of the Sun. Pokorny and Kuchner reasoned a group of asteroids in Venus’ orbit could have gone undetected until now because it’s difficult to point earthbound telescopes in that direction, so close to the Sun, without light interference from the Sun.
Asteroids represent building blocks of the solar system’s rocky planets. When they collide in the asteroid belt, they shed dust that scatters throughout the solar system, which scientists can study for clues to the early history of planets.

Co-orbiting asteroids are an example of what’s called a resonance, an orbital pattern that locks different orbits together, depending on how their gravitational influences meet. Pokorny and Kuchner modeled many potential resonances: asteroids that circle the Sun twice for every three of Venus’ orbits, for example, or nine times for Venus’ ten, and one for one. Of all the possibilities, one group alone produced a realistic simulation of the Venus dust ring: a pack of asteroids that occupies Venus’ orbit, matching Venus’ trips around the Sun one for one.
But the scientists couldn’t just call it a day after finding a hypothetical solution that worked. “We thought we’d discovered this population of asteroids, but then had to prove it and show it works,” Pokorny said. “We got excited, but then you realize, ‘Oh, there’s so much work to do.'”
They needed to show that the very existence of the asteroids makes sense in the solar system. It would be unlikely, they realized, that asteroids in these special, circular orbits near Venus arrived there from somewhere else like the asteroid belt. Their hypothesis would make more sense if the asteroids had been there since the very beginning of the solar system.
The scientists built another model, this time starting with a throng of 10,000 asteroids neighboring Venus. They let the simulation fast forward through 4.5 billion years of solar system history, incorporating all the gravitational effects from each of the planets. When the model reached present-day, about 800 of their test asteroids survived the test of time.
Pokorny considers this an optimistic survival rate. It indicates that asteroids could have formed near Venus’ orbit in the chaos of the early solar system, and some could remain there today, feeding the dust ring nearby.
The next step is actually pinning down and observing the elusive asteroids. “If there’s something there, we should be able to find it,” Pokorny said. Their existence could be verified with space-based telescopes like Hubble, or perhaps interplanetary space-imagers similar to STEREO’s. Then, the scientists will have more questions to answer: How many of them are there, and how big are they? Are they continuously shedding dust, or was there just one break-up event?

Dust rings around other stars
The dust rings that Mercury and Venus shepherd are just a planet or two away, but scientists have spotted many other dust rings in distant star systems. Vast dust rings can be easier to spot than exoplanets, and could be used to infer the existence of otherwise hidden planets, and even their orbital properties.
But interpreting extrasolar dust rings isn’t straightforward. “In order to model and accurately read the dust rings around other stars, we first have to understand the physics of the dust in our own backyard,” Kuchner said. By studying neighboring dust rings at Mercury, Venus and Earth, where dust traces out the enduring effects of gravity in the solar system, scientists can develop techniques for reading between the dust rings both near and far.

While Facebook CEO Mark Zuckerberg was testifying about Libra cryptocurrency before the House Financial Services Committee on Oct. 23, 2019, some viewers were focused on policy — but some were focused on his hair.
One person on Twitter pointed out that the short haircut might have something to do with Zuckerberg’s fascination with first century BCE Roman Emperor Augustus Caesar.
In a 2018 New Yorker profile, Zuckerberg revealed his admiration for the emperor — he and his wife even went to Rome for their honeymoon. He told the New Yorker, “My wife was making fun of me, saying she thought there were three people on the honeymoon: me, her, and Augustus. All the photos were different sculptures of Augustus.”
Zuckerberg and his wife even named one of their daughters August, reportedly after Caesar.
All of that admiration may be why Zuckerberg’s hairdo closely resembles “The Caesar” haircut (though the style is actually named after Emperor Julius Caesar, below).
Facebook did not respond to Business Insider’s request for comment on where Zuckerberg drew inspiration for his ‘do, so while we don’t know for sure, it’s possible the Caesars’ iconic cuts were the source.

A major US Navy station in Virginia Beach, Virginia, was placed on lockdown April 5 after an active shooter incident on the base.
NAS Air Station Oceana confirmed the incident on Twitter, and said that the perpetrator was “contained.” One person was injured, the station confirmed. Local news anchor Kristen Crowley reported the victim had a minor leg wound.
The base added that the victim was transported to hospital.
NAS OCEANA experienced an Active Shooter incident. The shooter has been contained. The victim has been transported to the hospital. More information to follow.
Naval Air Station Oceana previously announced the lockdown at 7:18 a.m., noting an unspecified “security incident.” It lifted the lockdown one hour later.
All gates to the base are closed and nobody can access it at this time, the Virginia Beach fire Department tweeted.
Police also warned people not to go near the area, local WAVY-TV reporter Katie Collett reported.
Footage outside the base tweeted by local 13NewsNow reporter Chenue Her showed dozens of people in uniform gathered at the entrance. Some of them can be seen hugging each other as they were let out of the base, Her noted.
I’m on my way to Oceana to follow this lockdown. I’ll have more info as soon as I find out. #13NewsNowhttps://twitter.com/13brianfarrell/status/1114128185556459520 …
I drove by the main entrance and it was severely backed up with traffic. Here’s a look down Oceana Blvd near a utility entrance with security at the gate and people gathering. #13NewsNowpic.twitter.com/hd0y6Sr0BJ
Bet you think you’re a good driver. No one can knife across three lanes of traffic and make an exit doing 73 mph like you can, hoss. You even throw around the occasional courtesy wave.
Former Army Engineer and “Oscar Mike” host Ryan Curtis fancied himself above average in the driving department until he met Jim Wilkey at Bobby Orr Motorsports, where the two-tour Vietnam Vet proceeded to hand our host his ass.
A former Navy Seabee, Wilkey is now one of Hollywood’s most highly-regarded stunt drivers, flipping cars and drifting in such modest cinematic offerings as “The Dark Knight” trilogy and “Mad Max: Fury Road.”
When he’s not rolling on “action,” Wilkey teaches the art of stunt driving to amateur road warrior wannabes on his home track in Camarillo, CA.
Watch as Wilkey puts Ryan through a day’s worth of paces and Ryan makes an unwise decision to challenge the master in a timed stunt lap, in the video embedded at the top.
An F-35 Joint Strike Fighter would be able to use its sensors, weapons and computer technology to destroy Russian and Chinese 5th-Generation Stealth fighters in a high-end combat fight, service officials said.
“There is nothing that I have seen from maneuvering an F-35 in a tactical environment that leads me to assume that there is any other airplane I would rather be in. I feel completely comfortable and confident in taking that airplane into any combat environment,” Lt. Col. Matt Hayden, 56th Fighter Wing, Chief of Safety, Luke AFB, Arizona, told Scout Warrior in a special pilot interview.
Furthermore, several F-35 pilots have been clear in their resolve that the multi-role fighter is able to outperform any other platform in existence.
While Hayden was clear to point out he has not, as of yet, flown simulated combat missions against the emerging Russian Sukhoi T-50 PAK FA 5th-Generation stealth fighter now in development or the Chinese Shenyang J-31 5th Generation Stealth aircraft. While he was clear to point out he did not personally know all of the technologies and capabilities of these Russian and Chinese aircraft, he was unambiguous in his assertion regarding confidence in the F-35. In addition, many Air Force officials have cited a strong belief that the F-35 is the best fighter in the world.
Available information says the Russians have built at least 6 prototype T-50 PAK FAs for their Air Force and Navy; the Chinese conducted a maiden test flight of its J-31 in 2012. In addition, China is in pre-production with its J-20 5th-Generation stealth fighter. This fighter, called the Chengdu J-20, made its first flight in 2011, and is expected to be operational by 2018, according to publicly available information and various news reports.
While Hayden did not elaborate on aspects of the J-20, he did say he would be confident flying the F-35 against any aircraft in the world.
“All those other countries (Russia and China) are trying to develop airplanes that are technologically capable as well — from an F-35 perspective. We are no less capable than any airplane and any fighters out there,” Hayden described.
In addition to leveraging the best available technologies on a fighter jet, winning a dog-fight or combat engagement would depend just as much on the air-tactics and decisions made by a pilot, Hayden explained.
“I have not flown against some of those aircraft. When you fight against an airplane, it depends upon the airspeed. If I maximize the effectiveness of an F-35, I can exploit the weaknesses of any other aircraft,” he said.
Many analysts have made the assessment that the J-20 does appear to be closely modelled after the F-35.
In fact, a Defense Science Board report, cited in a 2014 Congressional assessment of the Chinese military, (US-China Economic Security and Review Commission) makes reference to specific developmental information and specs of numerous U.S. weapons systems believed to be stolen by Chinese computer hackers; design specs and technologies for the F-35 were among those compromised by Chinese cyber-theft, according to the report.
An AIN Online report from the Singapore Air Show in February of this year catalogues a number of J-20 features and technologies – including those believed to be quite similar to the F-35.
“The J-20 is a large multi-role fighter with stealthy features similar to those found in the American F-22 and F-35. Although very little is known about its intended purpose, the aircraft appears to offer capability in a number of roles, including long-range interception and precision attack.
In terms of weapon carriage the J-20 has a similar arrangement to that of the Lockheed Martin F-22, comprising two lateral bays for small air-to-air missiles such as the agile, imaging-infrared PL-10, and a large under-fuselage bay for accommodating larger missiles and precision-guided surface attack weapons. The 607 Institute’s new PL-15 active-radar missile is thought to be the primary long-range air-to-air weapon, reportedly having been test-fired from a Shenyang J-16 platform last year. The PL-21, a ramjet-powered weapon in the same class as the MBDA Meteor, is another possibility for the J-20.
The sensor suite includes an electro-optical targeting system (EOTS) and a large-array AESA radar, which was developed by the 14th Institute at Nanjing Research Institute of Electronics Technology (NRIET, 14th Institute), and is possibly designated Type 1475/KLJ-5. Diamond-shaped windows around the fuselage suggest that a distributed aperture infrared vision system is installed.
In the cockpit, the J-20 sports three large color displays, plus other small screens, and a holographic wide-angle head-up display. An advanced datalink has been developed, and a retractable refueling probe is located on the starboard side of the forward fuselage. Much of the avionics suite has been tested by the CFTE (China flight test establishment) aboard a modified Tupolev Tu-204C, in much the same way as the systems of the F-22 were tested in a Boeing 757.”
Regarding the Russian T-50 PAK FA Stealth fighter, numerous reports suggest the aircraft has numerous technological problems and is a 5th generation plane “in name only.”
“Reporting from the Singapore Airshow 2016, IHS Jane’s reports that “Russian industry has consistently referred to the Sukhoi T-50 PAK FA as a fifth-generation aircraft, but a careful look at the program reveals that this is an ‘in name only’ designation.”
This is largely because of a lack of evolutionary technology aboard the plane compared with previous jets that Russia and the US have designed. Indeed, the PAK FA’s engines are the same as those aboard Russia’s 4++ generation (a bridging generation between fourth- and fifth-generation aircraft) Su-35. Additionally, the PAK FA and the Su-35 share many of the same onboard systems.
And even when the PAK FA’s systems are different from the Su-35’s, the plane’s specifications are still not up to true fifth-generation standards.
RealClearDefense, citing Indian media reports that are familiar with a PAK FA variant being constructed in India, notes that the plane has multiple technological problems. Among these problems are the plane’s “engine performance, the reliability of its AESA radar, and poor stealth engineering.”
F-35 Sensor Fusion
Despite various reports about technologies being engineered into the Russian and Chinese 5th-Generation Stealth Fighters, it is in no way clear that either aircraft is in any way comparable to the F-35. Most publicly available information seems to indicate that the F-35 is superior – however, to some extent, the issue remains an open question. More information is likely to emerge once the Russian and Chinese aircraft are operational and deployed.
For example, the Chinese J-20 is cited as having an Electro-Optical targeting system, stealth configuration, datalink, AESA radar and precision weaponry quite similar to the F-35, according to the AIN report.
The computer algorithms woven into the F-35 architecture are designed to leverage early iterations of what could be described as early phases of “artificial intelligence.” Broadly speaking, artificial intelligence refers to fast-evolving computer technology and processors able to gather, assess and integrate information more autonomously in order to help humans make decisions more quickly and efficiently from a position of command-and-control.
“If there is some kind of threat that I need to respond to with the airplane, I don’t have to go look at multiple sensors and multiple displays from multiple locations which could take my time and attention away from something else,” Hayden added.
The F-35 software, which shows images on display screens in the cockpit as well as on a pilot’s helmet-mounted-display, is able to merge results from various radar capabilities onto a single screen for the pilot.
“The F-35 takes from multiple sensors around the airplane and combines them together in a way that is much more manageable and accessible — while not detracting from the other tasks that the pilot is trying to accomplish,” Hayden said.
For instance, the F-35’s Electro-Optical Target System, or EOTS, is an infrared sensor able to assist pilots with air and ground targeting at increased standoff ranges while also performing laser designation, laser range-finding and other tasks.
In addition, the plane’s Distributed Aperture System, or DAS, is a series of six electro-optical sensors also able to give information to the pilot. The DAS includes precision tracking, fire control capabilities and the ability to warn the pilot of an approaching threat or missile.
The F-35 is also engineered with an Active Electronically Scanned Array Radar, which is able to track a host of electromagnetic signals, including returns from Synthetic Aperture Radar, or SAR. This paints a picture of the contours of the ground or surrounding terrain and, along with Ground Moving Target Indicator, or GMTI, locates something on the move on the ground and airborne objects or threats.
Hayden added that the F-35 has been training against other F-35s in simulated combat situations, testing basic fighter maneuvers. Having himself flown other fighter aircraft, he explained that many other F-35 pilots also fly the airplane after having experience flying an F-16, A-10 or other combat aircraft.
“The F-35’s low-observable technology can prevent detection. That is a strength that other airplanes do not have,” he said.
F-35 and F-22
At the same time, senior Air Force leaders have made the point that F-35 technological superiority is intended to be paired with the pure air-to-air dogfighting ability of the service’s F-22 – a stealth aircraft, with its speed, maneuverability and thrust-to-weight ratio, is believed by many to be the most capable air-to-air platform in the world.
“Every airplane has flaws. When you design an airplane, you design an airplane with tradeoffs – give something else up. If I was flying against an adversary in actual combat, my job would be to exploit the enemy weakness and play to my strength. I can compensate for certain things,” Hayden explained. “There is a certain way to fly and fight in an airplane, using airspeed to maximize the turning performance of the airplane.”
During a public speech in 2015, the Air Forces Air Combat Commander, Gen. Hawk Carlisle, said the F-22 is engineered such that it can complement the F-35.
“You will use the F-35 for air superiority, but you will need the raptors to do some things in a high-end fight to penetrate denied airspace,” he said. “The airplane is designed for multi-role capability, electronic warfare and sensors. The F-35 will win against any fourth-generation airplane — in a close-in fight, it will do exceedingly well. There will be a combination of F-22s and F-35s in the future.”
Hayden further elaborated upon these claims, arguing that the F-35 has another set of strategic advantages to include an ability to use internally built sensors. This prevents the need to use external pods on a fighter jet which can add drag, slowing down and restricting maneuverability for an aircraft.
“As an F-35 pilot, I can carry bombs to a target area where I can now take out air-to-ground threats. You have to look at the overall picture of the airplane. The airplane was designed to overwhelm the battlespace in a non-permissive threatening environment where 4th-gen fighters are not going to persist,” he added.
The F-35 is engineered with a 25-mm gun and has the ability to carry and fire a wide range of weapons. The aircraft has already demonstrated an ability to fire an AMRAAM (Advanced Medium Range Air to Air Missile), JDADM (Joint Direct Attack Munition) or GBU 12 (laser-guided aerial bomb), and AIM 9X Sidewinder air-to-air missile.
So-called “Block 3F” software for the F-35 increases the weapons delivery capacity of the JSF as well, giving it the ability to drop a Small Diameter Bomb and 500-pound JDAM.
As a multi-role fighter, the F-35 is also engineered to function as an intelligence, surveillance and reconnaissance platform designed to apprehend and process video, data and information from long distances. Some F-35 developers have gone so far as to say the F-35 has ISR technologies comparable to many drones in service today that are able to beam a “soda straw” video view of tactically relevant combat locations in real time.
Finally, regarding dogfighting, it is pertinent to point out a “War is Boring” report from 2015 which cited an F-35 fighter pilot explaining how an F-16 was able to win a “mock dogfight” against an F-35; the F-35 Joint Program Office disputed this claim, saying the F-35 used in the scenario was in no way representative of today’s operational F-35s. The software, weapons and sensor technologies used in the mock dogfight were not comparable to the most evolved F-35.
Furthermore, F-35 proponents maintained that the aircraft’s advanced computer technology and sensors would enable it to see and destroy enemy fighters from much longer ranges – essentially destroying enemy fighters before they are seen.
The idea is to enable F-35 pilots to see and destroy enemies in the air, well in advance of a potential dogfight scenario. This can be explained in terms of a well-known Air Force strategic concept pioneered years ago by air theorist and pilot Col. John Boyd, referred to as the “OODA Loop,” — for observe, orient, decide and act. The concept is to complete this process quickly and make fast decisions while in an air-to-air dogfight — in order to get inside the enemy’s decision cycle, properly anticipate, and destroy an enemy before they can destroy you.
The F-35 is designed with long-range sensors and data fusion technologies such that, as a fifth-generation aircraft, it can complete the OODA Loop much more quickly than potential adversaries, F-35 advocates claim.
Mission Data Files
Described as the brains of the airplane, the mission data files are extensive on-board data systems compiling information on geography, air space and potential threats in known areas of the world where the F-35 might be expected to perform combat operations, Air Force officials explained.
Consisting of hardware and software, the mission data files are essentially a database of known threats and friendly aircraft in specific parts of the world. The files are being worked on at a reprogramming laboratory at Eglin Air Force Base, Fla., Air Force officials toldMilitary.com last year. The mission data files are designed to work with the aircraft’s Radar Warning Receiver engineered to find and identify approaching enemy threats and hostile fire.
The mission data packages are loaded with a wide range of information to include commercial airliner information and specifics on Russian and Chinese fighter jets. For example, the mission data system would enable a pilot to quickly identify a Russian MiG-29 if it were detected by the F-35’s sensors.
The mission data files are being engineered to adjust to new threat and intelligence information as it emerges. For instance, the system is engineered to one day have all the details on a Chinese J-20 stealth fighter or Russian T-50 PAK FA stealth aircraft.
As a high-visibility, expensive acquisition program, the F-35 has many vocal detractors and advocates; the aircraft has, to be sure, had its share of developmental problems over the years. some of these problems include complications with its main computer system, called ALIS, and a now-corrected engine fire aboard the aircraft. Overall, most critics have pointed to the program’s growing costs, something program officials claim has vastly improved through various money-saving initiatives and bulk-buys.
