But the fad didn’t make its debut on a famous red carpet or in an elegant fashion show — it’s the brilliant invention of the U.S. Navy.
Although no one has been officially accredited with inventing the bell bottom trouser, the flared out look was introduced for sailors to wear in 1817. The new design was made to allow the young men who washed down the ship’s deck to roll their pant legs up above their knees to protect the material.
This modification also improved the time it took to take them off when the sailors needed to abandon ship in a moments notice. The trousers also doubled as a life preserver by knotting the pant legs.
Magpul officials are challenging a recent Army safety message that states that the Gen M3 PMAG polymer magazine breaks in extreme cold weather conditions.
U.S. Army TACOM Life Cycle Management Command Maintenance Information Message 17-045 states that “tests demonstrate PMAG magazines crack/break in cold (below 0 degrees Fahrenheit) environments when dropped and units should use Army-standard aluminum magazines in basic to severe cold environments.”
But Magpul Vice President Duane Liptak argues that the Gen M3 – the latest version of the PMAG that has been adopted by the U.S. Marine Corps and the Air Force – will continue to function more reliably than the Army’s new aluminum Enhanced Performance Magazine after drop tests at minus 60 degrees Fahrenheit.
“We strongly feel that there is either an error in their test methodology or their criteria for what they are considering pass/fail,” Liptak told Military.com recently.
“We have absolutely seen nothing from an extensive body of cold weather testing laboratory testing as well as extensive field use in arctic conditions to suggest any lack of suitability. In fact we have significant input from both fronts that it is superior to the USGI in those environments.”
The Marine Corps, U.S. Special Operations Command and the Air Force have selected the Magpul Gen M3 PMAG over the Army’s Enhanced Performance Magazine, or EPM.
But the Army has been reluctant to follow the other services and is sticking with its EPM.
Since its 2016 adoption, the Army has fielded more than 400,000 EPMs despite a 2015 U.S. Army Aberdeen Test Center report that shows the Gen M3 outperformed the EMP along with nine other commercial polymer magazines.
When developing the Gen M3, Magpul officials said one of the main goals was to pass a drop test at minus 60 degrees Fahrenheit, the U.S. Army standard for extreme cold weather.
“Negative 60 was the goal for the Gen M3,” Liptak said.
Magpul used test criteria of the Army’s Picatinny Arsenal, Liptak said.
The test involves an M4A1 loaded with a full Gen M3 PMAG after it is kept in a special chamber at minus 60 F for 72 hours, Liptak said.
“The most violent drop is the full weapon drop test; it is five feet in various orientations onto a polished concrete surface, in free-fall” Liptak said.
“It’s dropped in normal orientation which is magazine directly down, and that is the most damaging one to every magazine because that back corner hits. There are also sideways drops, a drop on the top of the rifle, a butt first drop and a nose first drop”
Liptak acknowledges that the Gen M3 PMAG will show minor cracking after the test, but it will continue to function reliably.
Apparently, Picatinny’s criteria only tests for cracking and breakages, not functioning, Liptak said.
“There was no live-fire performance qualification required so an aluminum mag bends all to Hell, binds the follower or spring, but it doesn’t crack so therefore it’s a pass,” Liptak said.
The PMAG will suffer tiny cracks, without spreading, in the floorplate, the over-travel stop and the mag catch – “all those things combined are to some extent sacrificial surfaces where they take some damage but the magazine is completely functional and that is our biggest criteria. Our thing is no matter what happens it needs to function.”
Liptack maintains that the Army’s EPM in many will be unable to function after the same drop tests.
“So what you will see is the base of the magazine will bend to a degree that impinges on the spring or the follower; sometimes the body itself will buckle sideways and that will impinge on the spring or the follower,” Liptak said.
Military.com reached out to the Army about this story but did not receive comment by deadline.
Magpul maintains that there are surfaces on the Gen M3 that are expected to have “small cracks when you drop it at minus 60, which is brutal,” Liptak said. “It’s a tough test. Like I said ‘the USGI doesn’t fair very well nor does anything else.
“Our criteria is function; the only thing we care about is function, so if the magazine fires 30 rounds after the drop it is considered a pass.”
US F-22 stealth fighters have returned to the Middle East to “defend American forces and interests” at a time of high tension with Iran, although it is unclear whether the advanced air superiority fighters have been deployed as part of the ongoing deterrence mission or for some other purpose.
An unspecified number of US Air Force F-22 Raptors arrived in the US Central Command area of responsibility June 27, 2019, flying into Al Udeid Air Base in Qatar, US Air Forces Central Command (AFCENT) said in a statement June 28, 2019.

This is the first time these fifth-generation fighters have flown into Qatar, as they have previously operated out of Al Dhafra in the United Arab Emirates, where a collection of US Air Force F-35A Lightning II Joint Strike Fighters are currently deployed.
The Aviationist’s David Cenciotti, citing sources, reported that nine F-22s with the 192nd Fighter Wing, Virginia Air National Guard at Joint Base Langley-Eustis in Virginia have flown into the region with at least three more expected to follow at a later point in time.
Photos of the aircraft flying in formation showed at least five fighters.

The US Air Force deployed F-15C Eagles to the Middle East in early 2019 to replace F-22s after years of regular deployments to the region.
“There are currently no F-22s deployed to AFCENT, but the United States Air Force has deployed F-15Cs to Southwest Asia,” AFCENT told Air Force Magazine in March. “US Air Force aircraft routinely rotate in and out of theater to fulfill operational requirements, maintain air superiority, and protect forces on the ground.”
But now these unmatched air assets are back in the region, and their arrival, likely part of a routine deployment, comes as US troops, weapons, and equipment are increasingly moving into the CENTCOM area of responsibility to deter possible Iranian aggression.

As sanctions crippled the Iranian economy, intelligence reports pointing to the possibility of Iranian attacks led the US military to send the USS Abraham Lincoln carrier strike group and a bomber task force to the Middle East to confront Iran.
Those assets were followed by more naval vessels, air-and-missile defense batteries, and thousands of additional troops.
In June 2019, Iranian forces shot down a US Navy drone, a serious escalation in the wake of a string of attacks on tankers, allegedly the work of Iranian forces.

Although the US was prepared to retaliate with airstrikes on Iranian positions, President Donald Trump said he called off the attack at the last minute, arguing that taking life in response to an attack on an unmanned system would be a disproportionate.
But after Iranian leadership issued a statement insulting the White House, Trump changed his tune. “Any attack by Iran on anything American will be met with great and overwhelming force. In some areas, overwhelming will mean obliteration,’ Trump tweeted.

The day after the September 11, 2001, terrorist attacks in New York City, newspapers captured the shock and horror. New York Post / Source: Newseum
The September 11, 2001, terrorist attacks happened exactly 19 years ago Friday.
For many people, the attacks were the biggest news story of their lifetime. Almost all who experienced it can remember where they were when they heard of the attacks.
Many people who remember that day also recall the following morning, when newspapers around the world captured the horror, shock, and sadness people felt.
The Newseum, a museum in Washington, DC, that chronicled the history of media, archived more than 100 newspapers from September 12, 2001, the day after the attacks. The front pages of these newspapers, bearing headlines like “ACT OF WAR” and “AMERICA’S DARKEST DAY,” underscore the impact the attacks had on the American psyche.
Here is what newspapers looked like the day after September 11, 2001.
Planes that lose competitions rarely get a second act. Just ask the YF-23 Black Widow II — two jets were produced and tested and now both will live out their days on display in museums. But there are a lucky few who have lost out only to get a second chance.
It’s rare, but, in a few cases, these runners-up made a huge impact with the United States military. The following planes made the most out of a second chance
The XF4F-3 Wildcat in flight. This plane got a second chance after earlier prototypes fell short against the Brewster F2A Buffalo, which turned out to be a real lemon in combat.
Grumman F4F Wildcat
Believe it or not, the extremely successful Wildcat almost never saw the light of day. The original version of this plane lost a developmental competition to the Brewster F2A Buffalo. Thankfully, the Navy gave the Wildcat a second chance, and this plane ended up holding the line against the Imperial Japanese Navy’s force of Mitsubishi A6M Zeros.
Boeing’s Model 299 did very well in the competition — until a fatal crash knocked it out of contention.
Boeing B-17 Flying Fortress
The prototype of the B-17, known as Model 299, initially performed extremely well. It was faster and more powerful than the competition. Unfortunately, the Model 299 crashed during its second evaluation flight, killing both pilots on board. With the Model 299 destroyed and disqualified, Douglas won the competition with the B-18
Fortunately, the Army Air Force, who were extremely impressed with the B-17’s performance, found a legal loophole through and kept the program alive. It went on to be the mainstay of the Eighth Air Force in World War II.
A version of the F-86 beat out the XF-88 Voodoo, but the plane survived as the basis for the F-101 Voodoo.
McDonnell XF-88 Voodoo
In 1946, the Army Air Force was looking for a long-range, jet-powered escort fighter. McDonnell offered up the XF-88 Voodoo to compete for this contract, which lost out to a version of the F-86 Sabre.
Combat in Korea quickly proved that the U.S. still needed an effective penetration fighter. So, McDonnell scaled up the XF-88 to make the prototype of the F-101 Voodoo, which entered service in 1957 and didn’t fully retire until 1983!
The B-1A was cancelled, but made a comeback in the 1980s as the B-1B Lancer.
In the eyes of the Air Force, the YF-17 was inferior to the F-16 Fighting Falcon, but the Navy saw something in this design. After making some modifications, this prototype become the classic F/A-18 Hornet, which still serves today!
If you look at a list of body parts men want to tone, somewhere up near the top, you’ll see abs. Sure, bulging biceps would be great, and you probably wouldn’t mind pecs that pop either. But abs — those elusive, sculpted, six-pack symbol of hyper-fitness — are universally sought on any fitness list. And yet, there is a cottage industry selling misguided, haphazard ab advice. The best abs workouts for men are pretty hard to come by.
The main problem is that many workouts don’t take into account that your midsection is actually composed of multiple muscles. The rectus abdominis is probably the one you know best: Running down your centerline from your sternum to pubic bone, this is the muscle people are typically talking about when they describe a six-pack. Then there are the obliques, technically two sets of muscles that run on diagonals beneath the rectus abdominis from your lower ribs to your hip bones. The transverse abdominus is even deeper still, wrapping around the sides of your torso and stabilizing your core. Your lower back muscles also play an integral role in defining your core — both aesthetically (they eliminate some of that side-fat overhang situation) and functionally (a strong lower back helps you rotate your core and stand more erect).
Not sure whether you’re hitting all the essential muscles in your core routine? The workout here has you covered. These 10 moves will sculpt your midsection into one lean, mean abdominal machine. Of course, no core workout will ever be a success if it’s not accompanied by eating smart and keeping up the cardio — if you’re carrying extra pounds, you’re going to have a gut, no matter how many planks you do.
One you can get through the below workout comfortably, add reps to your set, or sets to your circuit, to keep challenging yourself.
1. Flutter kick
Lie on your back, legs extended, heels about 6 inches off the ground. Place your hands by your sides or under the small of your back for support. Begin to scissor your legs up and down, as if you are doing the backstroke in the pool. Flutter kick for 20 seconds, rest 10, then do 20 seconds more.
2. Leg drop
Lie on your back on the floor, legs straight up in the air, feet together. Place your hands by your sides or under the small of your back for support. Without bending your knees, lower your legs to just above the floor, then raise them back to their vertical position. Do 10 reps, rest 10 seconds, then do another 10 reps.
Grab an 8-10 pound medicine ball or dumbbell. Sit on the floor, knees bent, feet flat in front of you. Hold the weight with both hands, arms straight in front of your chest. Lean back so that your body is at 45 degrees (mid-situp position). Twist to the right, letting your arms swing over to your right side. Twist back to the left, letting arms swing to the left side of your body. That’s one rep. Do 10 reps, rest 10 seconds. Do 3 sets.
Get into an extended pushup position, then lower yourself to your elbows. Keeping your body in a straight line from head to toe, hold the position for 60 seconds. For variations on the theme, try a side plank (prop yourself up on one elbow, then raise your hips off the ground to create a straight line from your feet to your shoulders).
From an extended pushup position, engage your abs and hike your hips into the air until your body forms an inverted V shape. Hold for three counts, then lower yourself back into an extended pushup position, keeping your back flat. Repeat sequence for 60 seconds.
Sit on the floor, knees bent, feet flat in front of you. Place a medicine ball between your feet. Lean back and lift your feet off the floor, straightening your legs until your weight is balanced in a V position. From here, either hold this position for 30 seconds, or for a more advanced challenge, bend and straighten your legs while maintain the V-hold. Relax, then repeat.
7. Side cable pull
Set the cable machine to a weight you can use for 8-10 reps. Stand perpendicular to the cable machine, left side closest, placing the pulley at chest height. Keeping your feet and hips stationary, twist your torso to the left and grab the pulley handle with both hands, arms straight. Pull the cable until your arms are straight in front of your body and your torso is straight over your legs. Hold for one count, then twist back toward the machine to return to the start position. Do 8-10 reps, then repeat on the opposite side. Do 2 complete sets.
8. Reverse crunches
Sit on the floor, knees bent, feet flat in front of you. Lean back so that your body is at 45 degrees (mid-situp position). Extend your arms in front of you as a counterbalance. Engage your abs and sink deeper toward the floor (don’t let your shoulders touch the ground), then immediately return to the start position. Pulse up and down for 30 seconds. Rest 10 seconds. Repeat for 30 seconds.
Using an overhand grip, perform a standard pullup. Once your head clear the bar, hold the contraction while bending your knees to your chest. (For a simpler version, hang from the pullup bar, arms extended. Bend your knees to your chest, then release them.) Do 8-10 reps, 30 seconds rest. 2 sets.
10. Diagonal chop
Set the cable machine to a weight you can use for 8-10 reps. Half-kneel perpendicular to the cable machine, left side closest to the machine and left knee bent in front of you (right leg on the floor). Place the pulley just above head height. Keeping your lower body stationary, twist to the left and grab the pulley handle with both hands, arms straight. Pull the cable on a diagonal until your arms are down at your right hip, torso twisted to your right side. Hold for one count, then twist back to the left to return to the start position. Do 8-10 reps, then repeat on the opposite side. Do 2 complete sets.

For most Americans, Kazakhstan evokes images of Sacha Baron Cohen’s Borat character, driving across America, uttering timeless quotes about his wife, his neighbor Ursultan, or those a**holes in Uzbekistan. Those interested in military history might want to look beyond Borat’s neon green bikini – it was a Kazakh who hoisted the Soviet flag over the Reichstag during World War II after all and until it was absorbed into the Soviet Union, Kazakh tribes remained largely undefeated in military history.
In 1969, a burial mound was discovered near Issyk in what was then the Kazakh SSR of the Soviet Union. The mound contained an ancient skeleton along with warrior’s gear and funeral treasures belonging to a long-dead Scythian soldier, estimated to be buried around the 5th Century BCE. Based on the funerary treasures, the skeleton was considered to be that of a noble, a prince or princess. Among those treasures was what has come to be called the “Golden Man” amongst Kazakhs – a suit of ornate armor made of more than 4,000 pieces of gold.
The suit is so ornate and valuable, the Kazakh government will only show replicas of the Golden Man in museums. The original is said to be housed in the main vault of the National Bank of Kazakhstan in Almaty.
The Prince is from a tribe of ancient Scythian warriors called the “Saka” who lived in the lands north of what is today Iran. While the ancient historians called all tribes living in the Asian steppe Scythian, the ancient Persians referred to those Scythian tribes at their northern border as the Saka. These nomadic peoples likely fought against Alexander the Great as his forces moved west. They also engaged Cyrus the Great’s Persian forces, killing him in battle around 530 BCE.
The Scythian tribes of this time were not dominated by men, and like their modern-day Soviet Kazakh armies, women would fight alongside their men. It was their Empress Tomyris who led the army that killed Cyrus. Descendants of these same tribes would resist incursions from early Russian, Chinese, and Roman armies.
So while it’s very possible the “Golden Man” wasn’t a man at all, the ancient, cataphract-style armor – armor used by nomadic-style cavalry units – is a beautiful historical work of art. The gold works depict snow leopards, deer, goats, horses, and majestic birds. These are all depicted on the likely ceremonial armor and form a clear basis for the modern style of tribal jewelry-making in the Central Asian country.
As for the bones of the ancient warrior, they were reinterred using the customs of the Scythian warriors of the time. The people of this area are still so very close to their tribal origins that they all know from which of the three tribes of Kazakhstan they descend.
Ernest Taylor Pyle was born on Aug. 3, 1900, at the turn of the 20th century. The famed war correspondent and columnist was better known as “Ernie” and had the reputation as the voice of the American servicemen during World War II. He chronicled the blitz in London and the individual heroism of Londoners, the roles of Vichy French officials in North Africa and their corroboration with the Nazis, and the allied invasions of both Italy and Normandy. One of his most heart wrenching pieces, “The Death of Captain Waskow,” revealed the emotional grief of soldiers when one of their men was killed in combat.
His refreshing writing style informed the general public back home and provided a rare look at the happenings of America’s sons, husbands, and fathers serving overseas.
Pyle’s birthday is now recognized as National Ernie Pyle Day. The day celebrates his wartime columns, his Pulitzer Prize for reporting, and the memory of his legacy, one that ended too soon. On April 18, 1945, Pyle was shot and killed by a Japanese soldier on the island of Ie Shima while he was covering the war in the Pacific. While there is plenty known about Pyle’s exploits from his famous dispatches, here are four lesser known stories of Ernie Pyle’s historic legacy that are worth mentioning on his day of remembrance.
Before Ernie Pyle became a war correspondent during World War II, it could be argued that he had already seen much of what the human experience had to offer from his travels around the globe. He suffered from restlessness, a common affliction for many in his chosen profession. The farm boy from Indiana had a curiosity in service, so he enlisted in the US Naval Reserves during World War I. However, that didn’t get him overseas, which left a burden and lingering question about the adventure waiting for him.
After leaving Indiana University, Pyle cut his teeth as an aviation reporter for the Washington Daily News under the helm of the Scripps Howard newspaper entity. His yarns received many compliments, including one by none other than aviator Amelia Earhart.
“Not to know Ernie Pyle,” she said, “is to admit that you yourself are unknown in aviation.”
“I’ve covered 200,000 miles and been on five of the six continents and crossed both oceans and delved into every country in the Western Hemisphere and written upward of 1,500,000 words in that, daily column,” Pyle wrote in July 1941. “I’ve gone down the Yukon River on a stem-wheeler, and lived with the lepers in Hawaii, and petted llamas in the high Andes, and reveled in the strange lazy beauties of Rio.”
His “Great Experience” halted when his quest of service took him to all three theaters of operations during World War II.

The ,000 Coca Cola Bottle
Coca-Cola was a prized beverage amongst American GI’s serving overseas in Europe during World War II. Pfc. Frederick Williams, a soldier from a field artillery brigade with prior service along the Italian front had returned home. He decided to send two bottles of Coke to his old unit, many of whom hadn’t seen a carbonated beverage for more than a year. The soldiers decided to split one of the Cokes and donate the other in a raffle to raise money for adoption efforts for the children whose fathers were killed in the brigade.
The Cokes were advertised in the brigade’s mimeographed newspaper for 25 cents a piece, and before the week was over the raffle had raised more than id=”listicle-2646905372″,000. Another soldier had received a second bottle of Coke and added the prize to the key. Three weeks passed and the total cash prize climbed to ,000.
“That one Coke was equivalent to the value of 80,000 bottles back home,” Pyle wrote in astonishment as he covered the event. Coke added an additional ,000 to the value and, despite the noble cause, Nazi propagandists used the opportunity to broadcast through the airwaves lies suggesting individual soldiers payed ,000 for one bottle of Coca-Cola.
In peacetime they are nickel-plated and shiny. In wartime they are black with a rough finish. A display at the National World War II Museum shows one of Pyle’s Zippo lighters donated during the war. Photo courtesy of the National World War II Museum.
Ernie’s Zippo Lighters
Readers from the United States and abroad were glued to the words Pyle strung together, including George Blaisdell, the president of Zippo Manufacturing Company. Braisdell sent a letter and 50 Zippo lighters personally addressed to Pyle to hand out to his servicemen friends.
“They’ll burn in the wind, and pilots say they are the only kind that will light at extreme altitudes,” Pyle once wrote. “Why, they’re so popular I had three stolen from me in one year.”
Pyle was an avid smoker, and through the habit he bonded with soldiers over a cigarette. “My own lighter was a beauty, with my name on one side and a little American flag on the other,” Pyle said. “I began smoking twice as much as usual just because I enjoyed lighting the thing.”
Conversations and insights happened while having a smoke that may not have occurred while sitting in a foxhole or over a meal of “C-rations” or in a bunk aboard a navy ship. Pyle’s ability to connect with pilots, infantrymen, medics, and even animals helped his writings convey a sense of identity and commonality to his readership.

Pyle and the War Dogs
Marines serving in the Pacific theater often named their military working dogs after terms familiar with the US military. Jeep, a black-and-brown Doberman pinscher, was utilized by Marines from the 3rd Marine Division. Pyle learned all about their war dog program, which consisted of 60 dogs, 90 handlers, 10 NCO observers, two K-9 medics, and three kennel supervisors. Jeep’s job as a scout and security patrolman helped the Marines locate sniper positions, search caves and pillboxes, alerted signs of potential ambushes, and ran messages to unit commanders.
Sergeant, another war dog that impacted Pyle and the Marines, was killed after he had been wounded by shrapnel from an air raid. The Marines specifically trained their dogs to run into foxholes when they heard the aircraft, but a lucky shot by the enemy resulted in Sergeant having to be put down.
“It is not belittling the men who died,” Pyle wrote of the tragedy, “to say that Sergeant’s death shares a big place in the grief of those who were left.”
Powerful punches, smooth moves, and acrobatic stunts are just some of the elements that make for an impressive action scene. To amp up a film’s imagery and add intensity, some filmmakers go a little beyond the standard fight and employ one of the most dramatic visual techniques: slow motion.
For years, movie directors have altered the frame rates on their cameras to either slow a sequence down or speed it up, based on how they want to tell a story.
Film historians credit August Musger, an Austrian priest and physicist, with inventing the slow-motion effect back at the beginning of the 1900s and, if you’ve been to the movie theater in the last decade, you’ve seen it employed today.
Now, filmmakers use the art of slow motion to allow audiences to pore over every detail of every frame of an intense sequence, to see the intricacies and beauty of an action in a different light. Sometimes, the technique doesn’t land well with audiences and comes across as trite and overplayed. In rare cases, however, the result is so badass that we end up watching the same few, magical seconds over and over again.
Although The Hurt Locker wasn’t a hit among many service members and veterans, director Kathryn Bigelow captured an epic opening sequence that involved cool camera work and a detailed explosion that ripples outward over a rugged landscape.
Who doesn’t like watching an awesome brawl between well-trained armies? That’s what Zack Snyder thought when he directed the combat-rich classic, 300. Although the film is filled with various slow-motion shots, it was best used when the audience runs alongside King Leonidas as he shreds members of the Persian army like it isn’t sh*t.
When the ultra-controversial action-comedy The Interview premiered in theaters, it drew in curious crowds who wanted to see if the film’s main characters were actually going to assassinate a fictional version of Kim Jong-un.
What we got was a slow-motion death scene so graphic that nobody could’ve predicted it.
A year after Hugh Jackman played Wolverine in X-Men, he played a computer hacker who was willing to break the law to reunite with his daughter. After being recruited to assist in a heist, the quickly goes awry, and filmmaker Dominic Sena gave us an explosion that the Wachowskis would be proud of.
Although this isn’t one of Brad Pitt’s most notable films, it does showcase one of the best up-close assassination scenes ever recorded.
The beautiful scene takes place on a moonlit, rainy night and gives the viewer the chance to watch every mechanical detail of a pistol firing rounds. Viewers watch tiny shards of glass fly through the air and see the wrinkles move on Markie Trattman’s (as played by Ray Liotta) face as he gets killed.
U.S. President Donald Trump has vowed to maintain U.S. dominance in space as China, Russia, and other countries make advances in the race to explore the moon, Mars, and other planets.
“America will always be the first in space,” Trump said in a speech at the White House on June 18, 2018, accompanied by Vice President Mike Pence and the National Space Council advisory body he created in 2017.
“My administration is reclaiming America’s heritage as the world’s greatest space-faring nation,” Trump said. “We don’t want China and Russia and other countries leading us. We’ve always led.”
While the United States has dominated in space since the 1969 moon landing, China recently has made significant advances, while Russia — which at the beginning of the Space Age in the 1950s had the world’s most advanced space progam — recently has mostly stagnated amid budget cutbacks.
Trump said he wants to stay ahead of strategic competitors like China and Russia, but he said he wants to nurture the space ambitions of private billionaires like Elon Musk, the founder of SpaceX, and Jeff Bezos, the founder of Amazon.com and the Blue Origin space company.

“Rich guys seem to like rockets,” Trump said. “As long as it’s an American rich person, that’s good, they can beat us,” he said. “The essence of the American character is to explore new horizons and to tame new frontiers.”
In his latest directive on space matters, Trump called for the Pentagon to create a new American “Space Force” that would become the sixth branch of the U.S. military — a proposal that requires congressional approval and is opposed by some legislators.
“We are going to have the Air Force, and we are going to have the Space Force, separate but equal,” Trump said.
The U.S. armed forces currently consists of the Army, Air Force, Marines, Navy, and Coast Guard.
“When it comes to defending America, it is not enough to merely have an American presence in space, we must have American dominance in space,” Trump said.
The Pentagon, where some high-level officials have voiced skepticism about establishing a separate Space Force, said it will work with Congress on Trump’s directive.
“Working with Congress, this will be a deliberate process with a great deal of input from multiple stakeholders,” Pentagon spokeswoman Dana White said.
Since his election, Trump has repeatedly vowed to send people back to the moon for the first time since 1972 — this time, he says, as a preparatory step for the first human missions to Mars in coming decades.
He has also promised fewer regulations to make it easier for private industry to explore and colonize space.
The U.S. commercial space sector already is booming under NASA policies that have shifted the role of the government away from being the sole builder and launcher of rockets for decades since the 1960s.
The U.S. space agency now mostly sees its role as working with private space companies like SpaceX and Orbital ATK to develop new space capabilities and carry them out.
SpaceX, which NASA currently pays to take cargo to the International Space Station, and Boeing are expected to start regular astronaut missions to low-Earth orbit in 2018.
Since 2012, when NASA’s space shuttle program ended, the U.S. space agency has also relied on Russian Soyuz spaceships to transport astronauts and cargo to the International Space Station.
Trump has said he wants to privatize the space station after 2025 — another idea viewed as controversial in Congress — so Washington can spend more on NASA’s plans to return astronauts to the Moon and eventually to Mars.
“This time, we will establish a long-term presence” on the moon, Trump said on June 18, 2018.
NASA is working with private industry on its most powerful rocket ever, called the Space Launch System, to send astronauts and their equipment to the moon and one day, Mars. It also wants to build a lunar outpost.
While seeking to create a new Space Force at the Pentagon, Trump also signed a directive on June 18, 2018, handing the Pentagon’s current authority to regulate private satellites to the Commerce Department.
He also issued a directive on space-traffic management, which is aimed at boosting the monitoring of objects in orbit so as to avoid collisions and debris strikes.
A statement released by the White House said the move “seeks to reduce the growing threat of orbital debris to the common interest of all nations.”
The Defense Department says there are 20,000 pieces of space debris and 800 operational U.S. satellites circling the Earth, a number that grows every year.
In the Hollywood blockbuster “The Core,” the planet’s core suddenly stops rotating, causing Earth’s magnetic field to collapse. Then bursts of deadly microwaves cook the Colosseum and melt the Golden Gate Bridge.
While “nearly everything in the movie is wrong,” according to Justin Revenaugh, a seismologist from the University of Minnesota, it is true that Earth’s magnetic field shields the planet from deadly and destructive solar radiation. Without it, solar winds could strip Earth of its oceans and atmosphere.
But the planet’s magnetic field isn’t static.
The Earth’s north magnetic pole (which is not the same as geographic north) has led scientists on something of a goose chase over the past century. Each year, it moves north by an average of about 30 miles.
The magnetic north pole has shifted north since the 1900s.
That movement made the World Magnetic Model — which tracks the field and informs compasses, smartphone GPS, and navigation systems on planes and ships — inaccurate. Since the next planned update of the WMM wasn’t until 2020, the US military requested an unprecedented early update to account for magnetic north’s accelerated gambol.
Now authors of a new study have gained insight into why magnetic north might be moving — and are learning how to predict these shifts.
Periodic and sometimes random changes in the distribution of that turbulent liquid metal can cause idiosyncrasies in the magnetic field. If you imagine the magnetic field as a series of rubber bands that thread through the magnetic poles and the Earth’s core, then changes in the core essentially tug on different rubber bands in various places.
Those geomagnetic tugs influence the north magnetic pole’s migration and can even cause it to veer wildly from its position.

So far, predicting these magnetic-field shifts has been a challenge. But in the new study, the geophysicists Julien Aubert and Christopher Finlay attempted to simulate the physical conditions of Earth’s core by having supercomputers crunch 4 million hours’ worth of calculations.
The researchers knew that the movement of heat from the planet’s interior outward could influence the magnetic field. In general, this happens at 6 miles per year. But they found that sometimes there are pockets of liquid iron in the core that happen to be much warmer and lighter than the surrounding fluid. If the difference between these hot, less dense bits of fluid and their colder, denser counterparts is great enough, the warm liquid can rise very quickly.
That rapid motion then triggers magnetic waves that careen toward the core’s surface, causing geomagnetic jerks.
“Think about these waves like vibrating strings of a musical instrument,” Aubert told Business Insider.
Magnetic north is important for navigational models
Keeping tabs on magnetic north is imperative for European and American militaries because their navigation systems rely on the WMM. So too do commercial airlines and smartphone GPS apps, to help pilots and users pinpoint their locations and navigate accordingly.
That’s why the British Geological Survey and the National Oceanic and Atmospheric Administration update the WMM every five years. The early update requested by the US military was completed Feb. 4, 2019.
But even with these periodic updates, geomagnetic jerks make it tough to keep the model accurate, Aubert said.
His group’s new model could address that problem by helping to predict how Earth’s magnetic field might evolve.
“Within the next few years, we envision that it should indeed be possible for our groups … to capture past jerks and predict the future ones with improved accuracy,” Aubert said.
Could the magnetic field ever collapse?
Earth’s magnetic field shields its atmosphere, which does “a bulk of the work” of keeping out solar radiation, as Revenaugh put it. If we lost our magnetic field, we’d eventually lose our atmosphere.
But according to Revenaugh, that’s extremely unlikely to happen, since the Earth’s core would never stop rotating.
Even if the field did collapse, the devastating effects depicted in “The Core” — people with pacemakers dropping dead, out-of-control lightning storms, eviscerated national landmarks — wouldn’t follow.
Without its atmosphere and magnetic field, Earth would constantly be bombarded by cosmic radiation.
A far more likely scenario, Revenaugh suggested, would involve the magnetic poles reversing as they did 780,000 years ago. When such reversals happen (there have been several in Earth’s history), the magnetic field drops to about 30% of its full strength, he said.
Though that’s a far-away scenario, Revenaugh added that it’s still important to improve scientists’ understanding of the magnetic field today.
“The better we can model it, the better we can understand what’s it’s up to,” he said.

In 2009, the Department of Defense acquisition chief John J. Young, Jr. issued a mandate requiring the military departments to find new ways to reduce their use of hexavalent chromium (also known as hex-chrome or Cr6+). Hex chrome, which became infamous in the eyes of the public after the release of the film, Erin Brockovich, is a carcinogen that is harmful to humans and the environment. DoD maintenance facilities go to painstaking lengths to reduce the level of exposure sustained by their maintenance technicians due to hex chrome.
Hex chrome offers important corrosion prevention and control qualities in organic pre-treatments and primers used to coat a variety of military aircraft. For example, most coatings and primers used on legacy fighter and cargo aircraft such as the Navy’s F/A-18 and F-14, the Air Force’s C-130, C-5, and F-16 contain hex chrome, and the Army’s H-60 Black Hawk helicopter.
Chromate-based corrosion inhibitors are widely recognized as the best inhibitors available to the DoD. Their high level of performance means that they are still used prolifically as a coating for all types of military aircraft.

The Delicate Balance of Finding Alternatives to Hex Chrome
Complicating the issue of finding alternatives to hex chrome is the drastic cost of corrosion faced by the U.S. military. According to a study released by the DoD Corrosion Policy and Oversight Office, the DoD spent nearly $20 billion on corrective corrosion actions in fiscal year 2016. That expenditure amounts to nearly 20 percent of the entire DoD maintenance budget.
Moreover, corrosion experienced by Navy and Marine Corps aircraft costs approximately $3.43 billion annually and accounts for almost 28 percent of all maintenance costs. Corrosion-related maintenance prevents active aircraft from being ready for mission tasking for approximately 57 days each year.
The high cost of corrosion within the DoD persists despite its prolific use of carcinogenic, but best-in-class, chromate primers.
Navy experts who attack the problem of chromates walk a delicate line between finding an environmentally benign inhibitor and refusing to sacrifice so much performance that the DoD maintenance budget swells even further. Since 2009, the search by DoD and industry for a non-chromate primer has persisted alongside the expectation of finding an alternative that performs just as well as current chromate-based primers. Among DoD officials and engineers, this expectation has become known as the “as good as” requirement.
In response to Young’s 2009 mandate, experts at the Materials Engineering Division of the Naval Air Warfare Command – Aircraft Division (NAWCAD) in Patuxent River, MD, re-energized their internal primer research and development efforts in an effort to push the performance of non-chromated primers closer to that of chromated primers, since the products qualified at the time were the best available, but still not good enough for many naval aviation applications

To address this shortcoming, NAWCAD materials engineer Craig Matzdorf and chemical engineer William Nickerson, now with the Office of Naval Research, have invented their own solution to the problem. Their patented Active Aluminum-Rich (“Al-Rich”) technology is a powerful anti-corrosion chemical composition created for use in coating systems. The Al-Rich primer is a metalized, sacrificial, chromate-free, high-performance, anti-corrosion primer for use in all situations where a chromated primer is currently used.
“Al-Rich is superior to existing coatings based on the novel aluminum pigment that actively overcomes corrosion by electrochemical means,” said Matzdorf. “Current coatings rely on chemical inhibitors like chromate, which are less effective at fighting galvanic corrosion. We anticipate that the Al-Rich primer will reduce galvanic and other types of corrosion and its effect on the Navy’s cost and availability.”
Key Technology Components in Al-Rich Primer
Although metal-rich primers have existed for quite some time, there were some underlying problems. First, the most traditional metal-rich coatings, such as zinc-rich coatings, are far too heavy for aviation applications and are not effective on aluminum. Second, other metal-rich coatings did not have the longevity of performance in harsh operating environments. “The Al-Rich primer employs two unique approaches to alleviate these key issues and to provide corrosion protection at the level of chromate primers,” according to Matzdorf.
The first key component of the technology is the use of a specialty aluminum alloy as the pigment inside the primer. The alloy composition of this pigment is specifically chosen for its high efficiency. In turn, this high efficiency, in combination with the low density of aluminum, allows the coating to be applied at normal aviation thicknesses, thus eliminating weight concerns.
The technology’s second key component is a proprietary surface treatment applied to the pigment. By subjecting the primer’s pigment to a surface treatment, both the pigment’s overall level of performance and the primer’s overall length of performance are increased. A surface-treated particle boosts the performance of this metal-rich primer to meet the “as good as” requirement.
According to Matzdorf, these two key technology components combine to create a truly novel approach to non-chromated and high-performance primers. One area of Al-Rich primer’s performance excellence is its ability to reduce fastener-induced corrosion. Each time a titanium or stainless steel fastener is punched into the aluminum body of an aircraft, a potent corrosion cell is created. These corrosion cells cause prolific and expensive corrosion damage. For reasons that are likely to stem from its ability to protect aluminum electrochemically, the Al-Rich primer excels at preventing fastener-induced corrosion as well as filiform corrosion. In many scenarios, the Al-Rich primer outperforms its chromated counterparts at preventing these rampant corrosion problems.
Applications and Future Testing
Thus far, the Al-Rich primer has been applied to an Army H-60 helicopter, a NASA C-130 cargo plane, two Coast Guard H-60 tail sections, and various pieces of Navy support equipment. Engineers at NAWCAD have extensive lab data on this product and are now looking to test it extensively on a variety of DoD applications. However, to do so, the Navy needs to procure large batch sizes of the new primer. Because the Navy is not in the business of manufacturing commercial quantities of chemicals, it has begun licensing this Al-Rich primer technology to equipped and capable businesses.
Through funding sponsored by the Office of Naval Research over the next few years, the Navy plans to apply the new Al-Rich primer to larger and larger portions of its assets. Successful field demonstrations will allow the Navy to comply with the DoD mandate regarding hex chrome. According to officials at NAWCAD and the DoD Corrosion Policy and Oversight Office, Al-Rich primers represent an exciting new entry into the non-chromated anti-corrosion primer market.
