Bell has unveiled its proposed single-rotor design for the U.S. Army’s Future Attack Reconnaissance Aircraft (FARA), a cutting-edge helicopter that may be optionally manned.
The ‘360 Invictus’ helicopter will be loaded with a 20 mm cannon and integrated munitions launcher able to carry Hellfire missiles or rockets. It will be able to adapt for future weapons integration in order to fight in urban environments, according to Bell.
Bell showcased its design to reporters at its facilities in Arlington, Virginia on Oct. 1, 2019.
“The Army realized that they absolutely do need a smaller aircraft that’s … able to operate in urban canyons as well as out in mixed terrain,” said Jeffrey Schloesser, executive vice president for strategic pursuits at Bell.

Schloesser said the 360 Invictus has high-cruise speeds, long-range capabilities and advanced maneuverability, all intended to help it dominate a future battlespace.
“We have a solution that can accomplish those missions, but it’s also the lowest-risk, and therefore probably the lowest-cost aircraft, to be able to accomplish [that],” Schloesser said.
Keith Flail, vice president of advanced vertical lift systems, said the agile helicopter’s first flight is expected in the fall of 2022. It should be able to fly at speeds greater than 180 knots true airspeed, or more than 200 miles per hour; the aircraft will also have a supplemental power unit that can boost the aircraft’s speed in flight.
Loosely based on Bell’s 525 Relentless rotor system, the fly-by-wire computer flight control helicopter will be made in partnership with Collins Aerospace which will deliver a new avionics hardware and software suite. “[Collins] also has the ability to integrate capabilities with the MOSA, or modular open system architecture, onto the aircraft,” Flail said.
Some observers at Oct. 1, 2019’s event remarked how the streamlined, lightweight fuselage design of the 360 Invictus resembled the body of a shark, particularly the vertical canted ducted tail rotor, designed for optimized lift and propulsion.
“As we’re in the wind tunnel, as we’re looking at performance, as we’re looking at drag, everything on the aircraft, we’re very confident that we have a good story on … that design target,” Flail said.
In April 2019, the Army awarded Bell, a subsidiary of Textron, the contract to begin prototype and design work; but the company must compete against four other firms before the service downselects its options to move forward with its future helicopter.
They are: AVX Aircraft Co. partnered with L3Harris Technologies; Boeing Co.; Lockheed Martin’s Sikorsky; and Karem Aircraft.
Currently, the Army is developing FARA and the Future Long Range Assault Aircraft (FLRAA) along with other airframes as part of its larger Future Vertical Lift initiative, or FVL.
FVL, the Army’s third modernization priority, is intended to field a new generation of helicopters before 2030.
Flail said that Bell will have a full-scale model of its FARA design, which fits inside a C-17 Globemaster III for transport as well as a 40-foot CONEX box, at the annual Association of the U.S. Army show later this month.

Before he was teaching folks how to paint beautiful landscape sceneries, the late artist Bob Ross served in the U.S. Air Force. In fact, it was where he gained his inspiration for future paintings.
While working as a first sergeant at Eielson Air Force Base in Alaska, Ross is said to have been acquainted with snow-capped mountains that made regular appearances in his paintings. He began painting them during work breaks, where he was able to create a fast technique that allowed him to make art, even with little downtime.
One of the things Bob Ross is known for is his calm and quiet demeanor. This can also be traced back to his time serving in the military. He said, with his role of keeping others in line, he had to be mean. “[I was] the guy who makes you scrub the latrine, the guy who makes you make your bed, the guy who screams at you for being late to work.” Because of this, he vowed to raise his voice once retiring from the military. This, of course, led to his signature of speaking softly.
The beginning of a military career and a love for art
At 18 years old, Ross enlisted. It was 1961 and after basic training, he was given a job as a medical records technician. He served for 20 years, retiring as a master sergeant.
After going to a U.S.O class in Anchorage, Ross began painting as a hobby. However, he soon found that his style differed from his instructors, who were more apt to create abstract pieces. He later found a television show called The Magic of Oil Painting. The show’s unique style, led by Bill Alexander, a German painter, taught Ross to paint quickly. The method is commonly known as “alla prima” or “wet on wet,” allowing the artist to create an entire painting in 30 minutes. This is the same method that Ross would become famous for in his own right.
With the help of the show, Ross studied the technique and began adding his own skills, creating an entire style of landscape painting. He began selling his paintings and quickly found success, even making more from his paintings than he did from his Air Force salary.
In 1981, he retired from the service and turned to painting full time. Ross soon returned to his home state of Florida and joined his mentor, painting coach Bill Alexander, as a salesman and tutor for his brand, Alexander Magic Art Supplies Company.
Eventually, Bob Ross founded his own painting company.
Bob Ross Inc. incorporated his signature permed hair into its logo. Because of the popularity, Ross kept his permed hair going forward. Through the company, he was able to gain popularity and star in The Joy of Painting, which aired for 12 seasons on PBS from 1983-1994. The show allowed Ross to teach his own style of painting, narrating how to achieve certain results while using the wet-on-wet technique. His son, Steve, also appeared on the show and eventually became a Ross-certified painting instructor.
Ross passed away in 1995 from complications of lymphoma, leaving behind a $15 million business in art classes and painting supplies. His shows still air on PBS reruns, continuing to teach the masses his landscaping techniques. To see him at work, check out the following video:
The U.S. Space Force will incorporate National Guard units that already have a space-related mission, according to the head of Air Force Space Command.
“We rely very heavily on the Air National Guard and the Air Force Reserve forces, and that’s going to continue in the future,” said Air Force Gen. John “Jay” Raymond during his confirmation hearing before the Senate Armed Services Committee to become the new head of U.S. Space Command.
“They operate really critical capabilities. They provide a capacity, a resource capacity, and we’re going to rely on them. They’re seamlessly integrated,” he said June 4, 2019.
In March 2019, officials announced that Raymond had been nominated to lead U.S. Space Command. Pentagon officials said at the time that, if confirmed, he would continue leading Air Force Space Command along with U.S. Space Command. The current Senate version of the Fiscal 2020 National Defense Authorization Act legislation would also require Raymond to lead Space Force for at least a year.

Guard units across seven states already have space missions, Sen. Jeanne Shaheen, D-New Hampshire, said during the hearing. That includes roughly 1,500 airmen conducting space-related operations in Ohio, Alaska, Colorado, Florida, New York, Arkansas, and California.
Raymond’s comments come as other officials want to make sure there is a place for the Guard in the Space Force structure.
Last month, Air National Guard director Lt. Gen. L. Scott Rice said that, while details are still being worked out, ANG units are “all in” for space operations.
During an Air Force Association breakfast in Washington, D.C., Rice said the Pentagon is looking to leverage the state forces that already have space-related operations.

“My job is to make sure it works. How would I present the operational piece and the bureaucracy for a new Space Force? I would do it from those seven states. I would not do 54 states and territories of Space National Guard,” he said.
However, the Air National Guard is setting up two new space squadrons in two more states, which would also be incorporated into the Space Force structure in the near future, Rice said.
“We are looking at standing up more capability for space control squadrons in the Pacific,” he told reporters after his presentation at the breakfast, as reported by Federal News Network.
“We are under review on where we are going to do that and how we are looking at that. The timeline is within the next month, two new squadrons in two new states.”
He did not reveal the locations under consideration.

Picture this: you’re gearing up for a trip to space. You’ll be gone roughly six months, which means you’ll need a cool 180 pairs of underwear or so packed in your suitcase. That’s before you even get to clothes. Add in shirts, pants and socks and you’re quickly racking up a packing volume that simply won’t fit. Shipping costs a slick $7,500 per pound; unfortunately, there’s no affordable “if it fits, it ships” option into space.
So what’s left? They can’t take it with them, they can’t have it shipped in – instead, they make what they have last. In most cases, that means wearing a pair of underwear for three days to a week. Longer for items like shorts and shirts. Yes, you read that right. The same clothes are worn for days on end. Some items make it longer than others, with daily uniforms making it more than a month before they’re changed out.
Are you grossed out yet? Before you start turning up your nose at these astronauts’ methods, consider a few of the variables. They’re in a space with a cool, controlled temp, so there’s minimal sweating. Little physical exertion is needed for most for daily movements. The training they do to keep muscles working is scheduled, meaning they can change before doing their anti-gravity exercises.
There’s less sweat, less grime and fewer chances of getting dirty. Think about it: they can’t even drop sauce on their shirt.
However, the workout clothes are said to get pretty gnarly. After a week of exercise, astronauts said the clothes stand on their own and smell “toxic” from their sweat.
Where do the clothes go?
But that still leaves the question of what actually happens to clothes once they’ve been worn. There are a few options. Because reentering the Earth’s atmosphere is such a tight science, space is key. Packing the dirty clothes simply isn’t on the docket for the journey home. Instead, astronauts have to get creative with their laundry.
One method is to simply shoot clothes into the atmosphere — yes, littering with the laundry. They collect it, along with trash, and place it on an unmanned aircraft that shortly before had delivered supplies, and is now no longer usable called The Progress. It’s “de-orbited” from the Space Station and sent on a path where it will burn in the Earth’s atmosphere. No word on what these three or four trips per year do for the environment.
Another option is to use the soiled clothing for plant nutrients. There is no soil in space, so in order to sprout seeds, astronauts have been known to use their dirty laundry that contains nutrients to sustain the plants. Gross… but interesting that this works!
Will the technology exist in the future?
It’s unlikely that traditional laundry machines will soon (or ever) exist on the International Space Station. Due to the amount of water that it takes to clean clothes, scientists say it’s simply not feasible. It’s also not a practice that’s cost-effective. However, with more travelers heading to space, and for longer periods of time, NASA said the current method is too wasteful and needs to be reevaluated.
In recent months they’ve partnered with Procter & Gamble (P&G), the owner of Tide, to create space-safe technology. The company will start testing alternative methods of cleaning clothes in space, including a type of machine that uses minimal water and soap. New types of detergent will also be tested to lengthen clothes’ lifespan and stay clean without gravity.
When you think of famous musicians who have honorably served in the United States Armed Forces, the mind immediately goes to Elvis Presley — and how could it not? Photos abound of the handsome, young Elvis in a crisp Army uniform. When he arrived at the airport to attend basic training, the airport was mobbed with screaming fans.
Upon being drafted, Elvis Presley entered the United States Army in spring of 1958 and served until spring of 1960, receiving his discharge from the Army Reserve in 1964. At the time of his draft, he was the most well-known entertainer in the Armed Forces, but he didn’t let his fame get in the way of service. Despite being offered a safer, cushier role in the Special Services as more of an entertainer and recruiting tool, Elvis chose instead to serve as a regular soldier.
However, Elvis isn’t the only famed musician to serve their country. Let’s look at eight other musicians you might be surprised to learn served their country in the United States Armed Forces.
Tracy Lauren Marrow, better known by his stage name, Ice-T, is one of many young adults who found themselves turning to military service as a way out of a tough situation. Dealing drugs on the streets of Los Angeles to support himself, he knew he needed to turn his life around when his daughter was born.
Marrow enlisted in the Army and served four years in the 25th Infantry Division at the Tropic Lightning Schofield Barracks in Hawaii.
During his time in Hawaii, Marrow served as a squad leader at Schofield Barracks. It was during this time that he purchased musical equipment and began work to hone his skills, save money, and prepare to launch a career in music. As Ice-T, Marrow went on to a dynamic career, first as a Grammy Award-winning musician, rapper, and songwriter, then as an actor on television on the hit show Law Order: Special Victims Unit.
American rock legend Jimi Hendrix remains one of the most influential guitarists of all time, despite an incredibly short career of only four years.
Well known for his groundbreaking instrumentalization on electric guitar and his legendary performance at Woodstock, Hendrix entered the military as one of two choices given to him by police after being caught twice in stolen cars: it was prison or the military.
Hendrix enlisted in May 1961 and was assigned to the 101st Airborne Division and stationed in Kentucky. Hendrix next completed paratrooper training and was given the prestigious Screaming Eagles Award in early 1962.
However, it seems that Hendrix wasn’t well-suited to military service and was given an honorable discharge just six months later. While Hendrix later claimed that he received a medical discharge after breaking his ankle in a parachute jump, he was actually discharged due to “unsuitability” for service.
Johnny Cash receives an award from a Marine sergeant during his performance for military personnel at the naval station.
The Man in Black was first a man in uniform. Johnny Cash, singer, songwriter, and one of the bestselling musicians of all time, had a career that spanned decades, genres, and generations.
Before he was an award-winning musician, Cash served in the United States Air Force. At age 18 and directly after high school, Cash enlisted and attended basic training at Lackland Air Force Base and technical training at Brooks Air Force Base in Texas.
He was assigned to the 12th Radio Squadron Mobile of the Air Force Security Service in Germany as a Morse code operator, intercepting Soviet transmissions.
His earnings in the military allowed him to buy his first guitar while stationed in Germany and he actually formed his first band, the Landsberg Barbarians, in the Air Force. Upon his discharge, he took advantage of the GI Bill to attend a radio announcing course in Memphis before launching his country music career.
And if it weren’t for his time in Germany, we probably wouldn’t have this version of “I Walk the Line” to contemplate!
Singer, songwriter, and grassroots activist, Willie Nelson is one the most famous voices in country music. He’s well-known for his work supporting American farmers and advocating for the legalization of marijuana through his role as co-chair of the National Organization for the Reform of Marijuana Laws (NORML).
He grew up in Texas during the Great Depression. After tumultuous early years, he moved to Arkansas to live with his grandparents, and he began playing honkytonks to avoid field work.
After he left high school, Nelson enlisted in the Air Force and served for about nine months before receiving a medical discharge due to back issues.
And while he didn’t serve very long, he has stayed passionate about veteran issues throughout his storied career as a singer, songwriter, author, and actor, advocating for increased medical care for veterans and supporting veteran advocacy groups, helping to raise awareness about homelessness among veterans.
Yes, that MC Hammer.
Stanley Burrell, known professionally as MC Hammer, is an American hip-hop recording artist, dancer, and producer who enjoyed tremendous success during the 1980s and ’90s with hits such as “U Can’t Touch This” and “2 Legit to Quit.”
After graduating from high school in Oakland, Burrell took undergraduate classes in communications. Discouraged by his lack of success, he was at a crossroads. He vacillated between considering work as a drug dealer or a job in the military.
He ultimately decided to join the United States Navy for three years, serving as an Aviation Storekeeper 3rd Class at the Naval Air Station at Moffett Field in Mountain View, California, until his honorable discharge.
Jazz legend John Coltrane was one of the most influential saxophonists and composers of all time. Known for his own recordings (more than 50) and his collaboration with other jazz greats, including Miles Davis and Thelonious Monk, Coltrane died young of liver cancer but leaves behind an exceptional musical legacy.
To avoid being drafted by the Army in 1945 during World War II, Coltrane enlisted in the Navy on the day the first atomic bomb was dropped on Japan. He trained as an apprentice seaman and was sent to Pearl Harbor.
During this time, his musical talents came to light, and he joined the Melody Masters, the base swing band. By the end of his service, he had assumed a leadership role in the band, and it was during this time that he made his first recording with other Navy musicians, playing alto saxophone on jazz standards and bebop tunes.
With a career that has spanned more than six decades, Tony Bennett is the living voice of American pop standards, jazz classics and, more recently, contemporary duets with other legends such as Amy Winehouse and Lady Gaga. He has earned 19 Grammy awards, two Emmy awards and is a Kennedy Center Honoree. He has sold more than 50 million records worldwide.
However, before he was Tony Bennett, he was Anthony Benedetto, who was drafted into the United States Army in November 1944 during the final stages of World War II. As a replacement infantryman, he served across France and into Germany, and in March 1945, he joined the front line.
During active combat, Bennett narrowly escaped death several times and he participated in the liberation of a Nazi concentration camp, where American prisoners of war from the 63rd Division were also freed.
During his service, he also sang with the Army military band under the stage name Joe Bari, and played with many musicians who went on to have post-war music careers. Once discharged, Bennett studied at the American Theater Wing on the GI Bill.
George Strait with U.S. Army Chief of Staff Peter J. Schoomaker at the 2005 San Antonio Stock Show Rodeo, before Schoomaker swore in a new group of Army recruits in front of rodeo fans.
Country music singer, songwriter, and producer, George Strait, AKA the “King of Country,” is considered by many to be one of the most popular and influential country music artists of all time. George Strait is famed for his neo-traditionalist style, his cowboy look and 60 No. 1 Billboard country music hits.
In 1971, Strait eloped with his high school sweetheart, Norma, then joined the United States Army. He was enlisted in the Army from 1971 to 1975 and was stationed in part in Hawaii. While there, he launched what would become a lifelong career, singing with the Army-sponsored band called Rambling Country.
Strait’s commitment to the men and women of the Armed Forces has continued throughout his illustrious career. He even served as the spokesman for the Wrangler National Patriot program, which raises awareness and funds for American wounded and fallen military veterans and their families.
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.

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.

It’s no surprise that the U.S. military is constantly trying to stay on the bleeding edge of technology to give its troops the upper hand. But what might raise eyebrows is how deep they’re thinking about every strategic and tactical advantage.
What also might not be so obvious is the civilian tech out there that’ll help troops on the ground in the future.

Researchers at the university of Tokyo isolated the cells of a microscopic organism called the tardigrade. It looks like a fat cross between a walrus and an anteater, but the little guy is resistant to boiling temperatures, extreme cold, crushing pressures, and intense radiation that would instantly kill any human.
The December 2016 issue of Foreign Policy magazine reported the same researchers added the resistant DNA to human cells in a petri dish and bombarded the cells with X-ray radiation. They found that human cells configured with tardigrade DNA were 40 percent less damaged than regular human cells – resistant enough to withstand the radiation on the surface of Mars.
2. Bomb-detecting spinach.
It’s not just for Popeye anymore. A research team at MIT embedded nanoparticles onto spinach plants and when these particles come in contact with explosives, they bind together, causing a reaction that gives off an infrared signal and can be alerted to mobile phones via wifi.
Not only does the plant modification detect explosives in soil, but it can also detect them in groundwater. Moreover, the plant can be used to decontaminate soil and take reclaim environmentally damaged Earth.
3. Solar Cell Uniforms.
Not solar-powered uniforms, solar power uniforms – wearable solar cells. the University of Central Florida estimates a typical rucksack weighs 60-100 pounds and is full of devices that require batteries — NVGs, radios, and GPS devices, to name a few. Those same researchers estimate that U.S. troops in Afghanistan carry 16 pounds of batteries for every 72-hour mission. Wouldn’t it be great if they didn’t have to carry that extra weight?
That’s why they developed a supercapacitor, a strip of electronic ribbon they want to interweave with cotton for American uniforms. The new fatigues would come with clip-on adapters to use in charging their needed devices. The troops would be walking solar panels, never running out of juice while on the mission.
The tourniquet is a long-standing staple of the battlefield and has been since before recorded history. The standard tourniquet has come a long way in that time; strips of torn cloth are now specially designed for ease of use and maximum pressure. But now it’s about to make its biggest leap ever.
The Feinstein Institute for Medical Research in Manhasset, N.Y., is developing a “neural tourniquet” that is placed on a wound to electronically stimulate the spleen, ordering the red blood cells to clot wounds everywhere on a body. So far, researchers note that clotting with the e-tourniquet begins in as little as three minutes, cutting blood loss by 50 percent and bleeding time by 40 percent.
5. Electric training headphones.
The Halo Sport is currently in the realm of Olympic athletes. It’s a $700 headphone device containing electrodes that send an electrical current to the brain’s motor cortex. This strengthens the connection between the brain and muscles, improving muscle memory – giving athletes a bigger edge in competition.
If training with the Halo Sport gives athletes a performance edge in training, it could probably do wonders for getting new recruits and foreign armies up to speed on the tactics of future battlefields.
Awhile ago, United may have taken it one step too far – at the expense of one of its own.
Daniel Fandrei is a United Airlines pilot who says he was not credited with his employee benefits – his accrued sick leave – while he was deployed to Southwest Asia as Air Force Reserve pilot Lt. Col. Fandrei. He reportedly filed a complaint with the Department of Labor’s Veterans’ Employment and Training Service.
Fandrei is a KC-10 Extender pilot who spent December 2012 to March 2013 conducting mid-air refuelings in support of combat operations in the CENTCOM theater. According to the Justice Department, United did not give him the same benefits as other employees during that time.
The Uniformed Service Employment and Reemployment Rights Act ensures military reserve and guard members called to active duty do not experience penalties as a result of their service.
Under the USERRA, the federal government will file legal actions against things like car repossessions and home foreclosures for activated servicemembers. Fandrei joined the Air Force as an officer in 1990 and started working for United in 2000.
“Lt. Col. Fandrei has made many sacrifices to serve our nation honorably, including spending months away from his job and family,” U.S. Attorney Zachary T. Fardon of the Northern District of Illinois said in a statement. “When our servicemembers are deployed in the service of our country, they are entitled to retain their civilian employment and benefits, and to the protections of federal law that prevent them from being subject to discrimination based upon their military obligations.”
Fitness. The word conjures mental images of tight lycra clothing, 5K finish lines, and overcrowded rooms filled with clanking weights and the pungent odor of sweat. Fitness, however, is much simpler than what is being sold to you. Fitness is health, plain and simple — the pursuit of which is a lifetime endeavor.
The concept of improving fitness almost always focuses directly on the improvement of the physical body. However, mental and spiritual health play equally important parts in the equation. Setting the proper intention — the purpose of one’s physical pursuit is as important, if not more so, than the physical movement itself.
When it comes to fitness, goals are paramount. There are three simple questions you need to ask yourself:
Where do I want to be?
Where am I currently?
What is the healthiest path from No. 2 to No. 1?

Your goals are your own. They should not exist for anyone else, and should be clearly identified so a path to achievement can be established. Let’s say your goal is to squat 200 pounds. Why? How does that number improve your quality of life? Numerical goals are not wrong so long as you can identify the reason. For example, if you aspire to be an EMT who will regularly need to hoist a 200-pound person, the goal serves you well.
Take an honest, comprehensive look at your current fitness level. Avoid self-criticism and identify the areas which can use the most improvement. Can you push and pull your body weight through various planes of movement repetitively and with ease? Does each of your joints flex and extend to an appropriate degree without pain? I know blood pressure and cholesterol levels aren’t as sexy to consider as what your abs look like, but they are undeniably factors that will sooner inhibit your quality of life than any aesthetic variance will.
Identify your weakness, then attack it with verve. Experienced triathletes know this concept well. For those with a strong swim and a weak run, it is much more enjoyable to practice swimming. This does little to improve race results or fitness in general though. That weakness may be flexibility, balance, or elevated levels of stress.
Knowing where you are and where you want to be doesn’t mean anything without establishing a reasonable path from one to the other. This is the angle of the ladder you will climb to your goal. Time plays a crucial factor in this. If your goal is to squat that 200 pounds but you currently have physical difficulty getting off the couch, the goal is still achievable when the proper number of rungs are implemented at appropriate intervals.
Does the pursuit of your goal require detriment to other aspects of your health? If your goal is to complete a marathon for the sake of doing so and your training plan omits components of strength, power, speed, or agility, you may get to the finish line a little faster — but you are ultimately working against your own fitness.
If you can identify where you currently are and where you want to be but are unsure how to get from one to the other, fear not. In the coming weeks and months, I will address pertinent aspects of fitness programming, equipment, and ideology. Wherever you may be, let’s improve our fitness — and our quality of life, together.

Back in civilian life, there are plenty of high-intensity jobs that are perfect for those veterans who need a little more action than a cubicle can provide. Check out this list of 7 extreme occupations:
In 2011, the U.S. government spent about $718 billion on defense. That’s nearly half of all military spending on the planet. The other top 13 nations combined spent $695 billion.
While the yearly budget is spread out according to defense needs, some projects take the lion share. Case in point are weapon systems like the Virginia Class Submarine with a procurement cost of $76.6 billion and the V-22 Osprey at $95.2 billion. Although costly, they aren’t the most expensive military mega-projects of all time. Here’s the list:
1. Nazi Germany’s Atlantic Wall
Final cost: unknown
Although the final cost was never determined, the French portion alone would have cost $200 billion when adjusted for inflation.
In episode five of season eight of “Game of Thrones,” countless civilians were burned alive in dragon fire as the city of King’s Landing was “liberated” by Daenerys Targaryen from the tyrannical ruler Cersei Lannister.
Prior to the devastating attack, Daenerys’ advisers pleaded with her to spare civilian lives and she responded that a destructive show of force will actually be an act of “mercy” by sparing future generations from the oppression of Cersei.
Instead, Daenerys indiscriminately rained fire down upon helpless men, women, and children, even after it was clear victory was at hand. As the fleeing civilians died, they left only their charred bodies to line the streets in an ashen city.
A lot of people think the horrific genocide is a metaphor for US foreign policy, in the sense that an ostensibly benevolent and powerful leader justified the killing of thousands of innocents in the name of what she claimed was the greater good.
Many people took to social media and drew parallels between US foreign policy — and particularly the US invasion of Iraq under former President George W. Bush — and Daenerys’ unilateral attack:
Since the US launched the so-called “war on terror” following the terror attacks on September 11, 2001, over 480,000 people have been killed by direct war violence in Iraq, Afghanistan, and Pakistan — including at least 244,000 civilians, according to the Watson Institute’s Cost of War project at Brown University.
Many experts, including those behind the Costs of War project, have contended the US could’ve pursued non-military options to pursue those responsible for 9/11 and spared many lives in the process.
The US military is still present in Afghanistan and Iraq, and continues to conduct air strikes and drone strikes in many places as part of its global war on terror, among other military operations. In the fight against the Islamic State group, or ISIS, the US has killed thousands of civilians in Syria and Iraq. Recent reporting also suggests the US has killed civilians with strikes in Somalia.

Ah, the vaunted Blue Book, known throughout the U.S. Army for being the first drill guide for American land troops. It is more properly known as Regulations for the Order and Discipline of the Troops of the United States, and it was authored by Baron and Inspector General Friedrich Wilhelm von Steuben, but it wasn’t actually the first drill manual for American troops.

See, von Steuben came to the Americas in 1778, nearly three years after the battles of Lexington and Concord and over 19 months after the signing of the Declaration of Independence. So, von Steuben was falling in on an American army that already existed. Clearly, someone had some idea of how to drill them before that, right?
Included in the short work was a two-page primer, Instructions for Young Officers, by British Maj. Gen. James Wolfe. Wolfe was a hero of the British empire and had distinguished himself against the French in Canada.
A 2006 re-printing of the text is available online as a PDF, and the first section is a sort of “by-the-numbers” breakdown of poising, cocking, presenting, firing, and then re-loading the “firelocks,” another word for the firearms of the day. If you think it’s odd that “aiming” wasn’t part of that process, good catch. But that wasn’t a big part of an infantryman’s job at the time.
Muskets and similar weapons had entered the hunting world hundreds of years before the American Revolution, but most weapons still weren’t horribly accurate. So rather than “aiming,” soldiers before and during the Revolution “presented” their weapons. Basically, they pointed the weapons in the direction of the enemy formation. Good enough for imperial work.
A 1740 Austrian drill manual shows rather than tells how troops would perform key actions.
But even before 1764, colonial forces were using a manual of arms that was likely more useful for many young militiamen than the king’s manual. The Austrian Infantry Drill from 1740 is made up almost entirely of illustrations that show rather than tell how troops should ride in formation, march, fix bayonets, etc.
In a surprising bit of honesty, it even shows troops maintaining the line as troops on either side collapse in combat. It is crazy optimistic in showing only three people having fallen during at least one full exchange of gunfire, but, still.
At a time when as much as 15 percent of the population was unable to read, these illustrations would have been quite valuable. For them, it wouldn’t matter that the descriptions were in a foreign language. They can tell from the pictures which illustrations were showing the fixing and unfixing of bayonets, shouldering and unshouldering arms, and so on.
The cover page of a printed “Blue Book,” Baron and Inspector General Friedrich Wilhelm von Steuben’s Regulations for the Order and Discipline of the Troops of the United States.
For instance, chapter one of the book details what equipment was needed for soldiers, non-commissioned officers, and officers. Chapter two defines what leaders’ roles would be, and chapters three and four details what men were needed for an army company, regiment, and battalion.
It goes on from there, detailing how to recruit and train troops, how to employ a company in training and combat, and more. So, even militiamen who had taken advantage of older drill guides, like those from 1764 and 1740, would find plenty of value in von Steuben’s manual.
