The Air Force announced Ellsworth Air Force Base, South Dakota, has been selected as the preferred location for the first operational B-21 Raider bomber and the formal training unit, March 27, 2019.
Whiteman AFB, Missouri, and Dyess AFB, Texas, will receive B-21s as they become available.
The Air Force used a deliberate process to minimize mission impact during the transition, maximize facility reuse, minimize cost and reduce overhead.
“These three bomber bases are well suited for the B-21,” said Secretary of the Air Force Heather A. Wilson. “We expect the first B-21 Raider to be delivered beginning in the mid-2020s, with subsequent deliveries phased across all three bases.”
Ellsworth AFB was selected as the first location because it provides sufficient space and existing facilities necessary to accommodate simultaneous missions at the lowest cost and with minimal operational impact across all three bases. The Air Force will incrementally retire existing B-1 Lancers and B-2 Spirits when a sufficient number of B-21s are delivered.

“We are procuring the B-21 Raider as a long-range, highly-survivable aircraft capable of penetrating enemy airspace with a mix of weapons,” said Air Force Chief of Staff Gen. David L. Goldfein. “It is a central part of a penetrating joint team.”
Barksdale AFB, Louisiana, and Minot AFB, North Dakota, will continue to host the B-52 Stratofortress which is expected to continue conducting operations through 2050.
The Air Force will make its final B-21 basing decision following compliance with the National Environmental Policy Act and other regulatory and planning processes. That decision is expected in 2021 and is part of the overall Air Force Strategic Basing Process.
The Russian Army showed off the precision of its tank crews in a bizarre demonstration.
According to Zvezda, the media outlet of the Russian armed forces, T-80 tank crews conducted demonstrations during Army-2019 forum, held near Moscow. One tank crew had a marker attached to its main gun and, with the help of its stabilizer, drew five-sided star on an easel.
“Undeniable proof that American tank crews have been outgunned by their Russian counterparts in arts and crafts,” Rob Lee, a Ph.D. student focused on Russian defense policy, joked on Twitter.
The demonstration also included a fruit-focused portion.
With a knife attached to the tank’s gun, the crew halved a watermelon, sliced through what appears to be a smaller melon, and then, as the finale, chopped an apple in half.
According to Zvevda, this exercise was intended to show off the maneuverability of the tanks as they moved in unison in a muddy field.
US forces have also done silly things, although in a less official capacity. In 2017, a Navy fighter pilot drew a penis with contrails from his jet in the sky over Washington state, a stunt for which the flier was disciplined.

Some of our nation’s greatest treasures aren’t places, they are people. Leo LaCasse survived three crash landings and evaded 4,000 enemy troops during World War II. He now lives at a VA Community Living Center in Salem, Virginia. Here is his story:
Born on July 4, 1920, Leo LaCasse was one of five children–all of whom were born on birthdays of former presidents. At the age of 15, he joined the New Hampshire National Guard, and later the Army Air Corps, where he was assigned to a recruiting command. The private was soon promoted to corporal, then sergeant, as he traveled New England recruiting pilots from colleges and universities.
One day, Leo learned that he was accepted to flight school. It was a reward from his commanding officer who had submitted the application on his behalf. Despite never having gone to college, the Army sent Leo to college under an accelerated learning program, and when he graduated, he became a B-17 bomber captain.
Soon, flying planes “felt like home” to Leo.
“Some of them [planes] were cramped, but it didn’t make any difference to me because I was the pilot. When you’re packed in an aircraft and don’t have the room to move your body in the cockpit, any airplane you fly after that is good.”
In June 1943, Leo was assigned to the 8th Air Force, Bomb Group 548th in Suffolk, England, where he served under General Curtis Lemay.
Leo LaCasse flew 35 missions over Germany and other occupied countries, and survived three crash landings. During World War II, Leo evaded 4,000 enemy troops over 4 months.
One of Leo’s crashes landed in France, which was then occupied by Germany. He instructed his crew to head for the front lines, to surrender and tell whoever interrogated them that he was headed for Berlin. Instead, Leo left for Luxembourg to meet up with the French Resistance, where he crossed the Pyrenees Mountains, and made his way to Portugal.
In all, he spent four months avoiding Nazi capture. When the war was over, he was sent to Berlin for debriefing. That’s where he met and befriended a German general who recognized Leo’s name and revealed there had been 4,000 German troops looking for him following the crash landing in France.

Leo retired from the military as a Brigadier General. For his service he has received numerous medals including the Silver Star Medal, Distinguished Flying Cross, Purple Heart, Legion of Merit Air Medal, Air Force Commendation Medal, Air Force Combat Medal, Joint Services Commendation Medal, World War II Victory Medal, European and Middle East Campaign Medal, Army Air Force Medal, Armed Forces Reserve Medal, and the American Defense Medal.
On June 5, 2016, Leo received the Legion of Honor Medal, France’s highest honor.
Leo now resides at Salem VA Medical Center’s Community Living Center located in Salem, Virginia.
On July 4, 2019, Leo will celebrate his 99th birthday.

It’s not uncommon in war movies to see a pilot heroically struggle to save the lives of wounded crewmen on board a damaged plane as he brings her to the carrier or base. At the end of the 1976 movie Midway, for example, Matt Garth (as played by Charlton Heston) dies as he ends up on the wrong side of this struggle and suffers a bad ramp strike. Thankfully, not all such stories are so grim. In a recent incident, then-Capt. Kim “Killer Chick” Campbell successfully brought a shot-up A-10 back to base during Operation Iraqi Freedom.
But here’s something you may not know: These heroic actions don’t just take place during times of war. In peacetime, there are similar emergencies that force a crew to bring a damaged plane back to base – and it requires some heroic flying. One incident that our loyal readers know about involved an AV-8B Harrier with a nose gear failure. Capt. William Mahoney received the Air Medal in 2015 for pulling off the landing.
Well, the crew of a Navy EA-18G Growler electronic warfare aircraft recently pulled off a much more impressive feat and were recognized with the Air Medal for their actions. Lieutenants Jason Hirzel and Sean Noronha of Air Test and Evaluation Squadron Nine were flying their Growler from Whidbey Island Naval Air Station to the Navy’s test facility at China Lake on Jan. 29, 2018. Suddenly, their environmental control systems failed at 25,000 feet. They were blinder than proverbial bats after a mist filled their cockpit and temperature dropped to 30 below zero, causing the instruments and canopy to ice over.
“This is a situation that absolutely would have justified ejection from the aircraft,” a Navy spokesman said. “But the aircrew persevered through the extreme conditions and risked their lives to ensure a safe recovery of the aircraft.”
This amazing feat was accomplished by using a Garmin watch and a big assist from the ground control team at Whidbey Island.
The two crewmen suffered minor injuries, including frostbite. One has returned to flight status, the other is expected to do so soon.
People say “chivalry is dead” like that’s a terrible thing.
In the popular imagination, chivalry seems to harken back to some mythical era when armored knights rode about the land going on quests, saving maidens, and fighting evildoers.
But chivalry is really a word “that came to denote the code and culture of a martial estate which regarded war as its hereditary profession,” Maurice Keen writes in “Chivalry.”
He argues that medieval chivalry had a major part in molding “noble values,” and, as a result, has had an impact felt long after troubadours and jousting tournaments fell out of fashion. The romantic notion of the daring, pure-hearted knight errant lingers on, even today.
It’s difficult to speak broadly about the medieval era in Europe, given that it encompasses several centuries and an entire continent. Generally speaking, however, in many cases, knights and medieval warriors served as a local lord’s private military. That meant that sometimes, regional conflicts set a group of armed toughs tearing through the countryside and doing whatever the heck they wanted.
Codes of chivalry didn’t take hold in vacuum. There was no uniform “code of chivalry,” and those codes that existed were often far more religious in nature than our modern concept of “hold the door for ladies.” They also cropped up in part to keep knights and warriors from acting on their worst impulses and attacking or extorting weaker individuals.
Starting in the late 900s and lasting till the thirteenth century, a movement known as the Peace and Truce of God rose in Europe. Basically, the Church imposed religious sanctions in order to halt the nobility from fighting among themselves at certain times and committing violence against local noncombatants. You can think of these as rules for knighthood.
One 1023 oath, suggested by Bishop Warin of Beauvais for King Robert the Pious and his knights, gives us a good sense of some of the unexpected rules warriors might be asked to adopt, in response to their often violent behavior.
It includes some rather unusual injunctions and “illustrates the kind of oath that parties were expected to swear after having been caught breaking the peace,” according to Daniel Lord Smail and Kelly Gibson, who edited the sourcebook “Vengeance in Medieval Europe.” A main idea behind the movement was to use spiritual sanctions to give people a break from all the conflict and fighting that plagued certain areas at some points during the Middle Ages.
With that in mind, here are some of Bishop Warin of Beauvais’ proposed rules for knights, which indicate some truly bad and largely unchivalrous behavior on the part of medieval warriors:
1. Don’t beat up random members of the clergy
Bishop Warin of Beauvais barred knights from assaulting unarmed clerics, monks, and their companions, “unless they are committing a crime or unless it is in recompense for a crime for which they would not make amends, fifteen days after my warning.”
Gunald of Bordeaux also condemned anyone who “attacks, seizes, or beats a priest, deacon, or any other clergyman who is not bearing arms — shield, sword, coat of mail, or helmet — but is going along peacefully or staying in the house,” according to Fordham University’s medieval sourcebook.
Instead of formally cursing the offenders, Gunald vowed to excommunicate any attackers “unless he makes satisfaction, or unless the bishop discovers that the clergyman brought it upon himself by his own fault.”
2. Don’t steal livestock or kill farm animals for no reason
The oath includes an injunction against making off with bulls, cows, pigs, sheep, lambs, goats, donkeys, mares, and untamed colts.

It also came out against seizing mules and horses at certain times of the year: “I will not exact by extortion mules and horses, male and female, and colts pasturing in the fields from the first of March to All Souls’ Day, unless I should find them doing damage to me.”
However, the bishop of Beauvais allowed that knights could kill villagers’ animals if they needed to feed themselves or their men.
In Gunwald’s proclamation, he also announced that any knight who robbed a poor person of a farm animal would be formally cursed.
3. Don’t assault, rob, kidnap, and torture random people
This rule should have probably gone without saying, but Bishop Warin of Beauvais felt that he needed to include it in the oath.
The bishop wanted knights to swear against mistreating male and female villagers, sergeants, merchants, and pilgrims. This abuse he cited included robbery, whipping, physical attacks, extortion, and kidnapping for ransom.
4. Don’t burn down or destroy houses unless you have a good reason
Arson was a big no in the bishop of Beauvais’s oath — for the most part.
Exceptions were made in the event a knight discovered “an enemy horseman or thief within” a certain house.
That sounds harsh, but Kaeuper writes that, while wrath was a sin, “vengeance is a cornerstone of the chivalric ethos, the harsh repayment justly given for an dimunition of precious honor.”
“Nocturnal fire” by Egbert van der Poel (1621–1664)
Knights were also warned against plundering and stealing from the poor, even “at the perfidious instigation” of a local lord.
Kaeuper cite’s Alan of Lille’s declaration that knights achieved the “highest degree of villainy” by supporting themselves by looting from impoverished people.
5. Don’t assist criminals
Knights had a bad rap in certain parts.
Kauper writes that Alan of Lille once said that knights had the “cruel nature of marauders” and that “soldiers have been made the leaders of pillaging bands; they have become cattle-thieves.”
Considering such a borderline criminal element, it’s not surprising that the Bishop Warin of Beauvais wanted knights to swear not to harbor and assist any “notorious public robber.”
He allows that, if a criminal comes to a knight for protection, that the knight should either make amends for the wrongdoer, force him to make amends within fifteen days, or deny him protection.
6. Don’t attack women — unless they give you a reason
The oath included a stipulation telling knights not to assault noblewomen traveling without their husbands. It also expanded protection to those attending them, along with widows and nuns, in general.
However, this shield was revoked if a knight “should find them committing misdeeds against” him.
7. Don’t ambush unarmed knights from Lent to Easter
A major part of the Peace and Truce of God movement was declaring that fighting should not take place during certain parts of the year.

Yale Law School’s Avalon Project features a 1085 decree from Emperor Henry IV, which declares that peace should be observed every Thursday, Friday, Saturday, and Sunday, on apostles’ feast days, and from the ninth Sunday before Easter until the eighth day after Pentecost, among other times.
In a similar vein, Bishop Warin of Beauvais ordered medieval warriors not to attack unarmed knights “from the beginning of Lent until the end of Easter.”

We Are The Mighty wants to wish a very Happy Birthday to our favorite racecar driver. Jesse Iwuji turns 33 today, and we are wishing him the happiest of days. While his birthday is no doubt a special day, this year’s celebration is a bit more sweeter.
As many of you know, Jesse is unique among NASCAR drivers. He is a Naval Officer who is following his dreams of becoming a racecar driver. That dream took a big step up this week.
Jesse was recently promoted into NASCAR’s Xfinity Series where he will be driving the No. 13 Toyota Supra for MBM Motorsports. He will continue to also race the No. 33 Chevrolet Silverado for Reaume Brothers Racing in the NASCAR Gander RV & Outdoors Truck Series.
In addition to the promotion in NASCAR, Jesse also was promoted to Lieutenant Commander in the United States Navy – talk about having an amazing month.
Here are some of Jesse’s friends, family, superior officers, fellow drivers and colleagues wishing him a happy birthday. You can tell the impact a man has from the company he keeps, and this collection of amazing people shows just how awesome Jesse is and why WATM is such a big fan:
Jesse Iwuji NASCAR Xfinity Series Debut at Road America | US Navy | Military | Congratulations
Jesse was born on August 12, 1987, the son of Nigerian immigrants. Born and raised in Texas, he was an athlete in high school and excelled in both sports and school. That excellence landed him at the United States Naval Academy. Jesse played for the Midshipman while learning to be a Surface Warfare Officer. In addition to playing safety, Iwuji also ran track for the Naval Academy.
He graduated in 2009 and went into the Fleet, first working on mine countermeasures which included a deployment to the Persian Gulf in 2012. He later served on the USS Comstock before moving into the Naval Reserves in 2017.
Moving into NASCAR is no easy feat. But with his belief in honor, courage and commitment, Iwuji pushed forward through all the obstacles. He first thought about becoming a racecar driver during a Navy football event at the Meineke Car Care Bowl. Throughout his active duty career, he balanced his duties and deployments with his pursuit of his passion. Upon entering the Reserves, he started accelerating his career with stints in the NASCAR KN Pro Series East and West which are regional proving grounds for drivers looking to prove themselves on the stockyard circuit.
From there, he moved into the truck series where he has competed for the last three years. His recent promotion to the Xfinity Series puts him one step closer to the NASCAR Cup Series which is, for those of you who don’t know, the highest echelon of stock car racing in the world.
Jesse’s debut on the Xfinity circuit was at the Henry 180 where he finished the race in the 26th spot. His next race should be at the legendary Watkins Glen road course this weekend.
Hopefully soon, we will see him racing in the Cup Series at places like Daytona, Talladega, Martinsville, Dover and Bristol.
Happy Birthday Jesse and congratulations on both your promotions!
A former director of the veterans hospital in the nation’s capital who had been fired for poor leadership has been rehired.
Brian Hawkins was put back on the Department of Veterans Affairs payroll after he appealed the decision to the Merit Systems Protection Board. Hawkins was let go last month after audits found mismanagement at the facility.
The board is requiring the VA to keep Hawkins as an employee until the Office of Special Counsel reviews his claim.
In a statement August 9, the VA says Hawkins had been reassigned to administrative duty at VA headquarters in Washington and would not work directly with patients.
It says VA Secretary David Shulkin will explore other ways to fire Hawkins under a newly enacted accountability law signed by President Donald Trump.
A sailor from the amphibious assault ship Boxer is believed to have tested positive for the new coronavirus disease just nine days after military family members visited the ship at sea.
This marks the first coronavirus, or COVID-19, case for a sailor who was aboard a Navy ship. The person is now quarantined at home, Navy officials said in a Sunday night news release. The sailor’s test result for the sometimes-fatal virus is considered presumptive positive, pending confirmation by the Centers for Disease Control and Prevention.
This will likely be a new challenge for the sea service, since infections and viruses can spread quickly among crew members who live in close quarters. That has been the case for several civilian cruise liners, which has resulted in widespread cancellations for the industry.
Sailors and their family members watch an AH-1W Super Cobra, attached to Marine Light Attack Helicopter Squadron (HMLA) 267, take off on the flight deck of amphibious assault ship USS Boxer (LHD 4) during a family day cruise (FDC).
The San Diego-based Boxer on March 9 held a family day cruise, allowing military families to visit the crew on the ship in the Pacific Ocean, according to official Navy photos. Civilians can be seen riding a Landing Craft Utility vessel into the Boxer’s well deck and standing on the ship’s flight deck observing Marine Corps helicopter takeoffs at sea.
Navy officials did not immediately respond to questions from Military.com about whether one of those family members is believed to have unwittingly exposed the crew member to the coronavirus. It’s not immediately clear how many family members were on the ship as part of the event or how many sailors and Marines were onboard.
Personnel who came in close contact with the sailor have been notified and are in self-isolation in their homes, according to the Navy news release. None of those people are currently onboard the ship.
Military health officials are working to determine whether any additional personnel were at risk of exposure, the release adds.
“Depending on the results of that investigation, additional mitigations may be taken,” it states.
Navy ships are routinely cleaned to prevent the spread of communicable diseases.
“USS Boxer is taking appropriate preventative measures and conducting a thorough cleaning in accordance with specific guidance from the CDC and Navy-Marine Corps Public Health Center,” the release says.
The service closely coordinating with state, federal and public health authorities to ensure the wellbeing of Navy personnel and the local population, officials said.
The bomb-disposal team removed the bomb with a lifting bag and dragged it down the Thames overnight to Shoeburyness, a coastal town 60 kilometers east of the bomb’s original location, a Royal Navy spokeswoman told Business Insider.
The unexploded ordnance is now at a military range in the sea off Shoeburyness, Essex. The Navy plans to attach high-grade military detonators to blow it up.
The bomb-disposal team originally wanted to detonate the bomb on Feb. 13. It has since postponed the operation because of poor weather conditions, the Royal Navy said.
Cmdr. Del McKnight of the Royal Navy’s fleet diving squadron said in a statement on Feb. 13:
The bomb presents no risk to the public in its current location, so we will leave it where it currently sits until tomorrow.
The area where the airport stands used to be an industrial center, and it came under heavy bombardment from German planes during the war. Unexploded bombs still occasionally turn up during construction work.
NASA has selected 12 science and technology demonstration payloads to fly to the Moon as early as the end of 2019, dependent upon the availability of commercial landers. These selections represent an early step toward the agency’s long-term scientific study and human exploration of the Moon and, later, Mars.
Watch This Space: The Latest from the Moon to Mars
“The Moon has unique scientific value and the potential to yield resources, such as water and oxygen,” said NASA Administrator Jim Bridenstine. “Its proximity to Earth makes it especially valuable as a proving ground for deeper space exploration.”
NASA’s Science Mission Directorate (SMD) initiated the request for proposals leading to these selections as the first step in achieving a variety of science and technology objectives that could be met by regularly sending instruments, experiments and other small payloads to the Moon.
“This payload selection announcement is the exciting next step on our path to return to the surface of the Moon,” said Steve Clarke, SMD’s deputy associate administrator for Exploration at NASA Headquarters in Washington. “The selected payloads, along with those that will be awarded through the Lunar Surface Instrument and Technology Payloads call, will begin to build a healthy pipeline of scientific investigations and technology development payloads that we can fly to the lunar surface using U.S. commercial landing delivery services. Future calls for payloads are planned to be released each year for additional opportunities,” he said.
Armstrong and Aldrin landed on the Moon July 20, 1969.
The selected payloads include a variety of scientific instruments.
The Linear Energy Transfer Spectrometer will measure the lunar surface radiation environment.
Three resource prospecting instruments have been selected to fly:
The Near-Infrared Volatile Spectrometer System is an imaging spectrometer that will measure surface composition.
The Neutron Spectrometer System and Advanced Neutron Measurements at the Lunar Surface are neutron spectrometers that will measure hydrogen abundance.
The Ion-Trap Mass Spectrometer for Lunar Surface Volatiles instrument is an ion-trap mass spectrometer that will measure volatile contents in the surface and lunar exosphere.
A magnetometer will measure the surface magnetic field.
The Low-frequency Radio Observations from the Near Side Lunar Surface instrument, a radio science instrument, will measure the photoelectron sheath density near the surface.
Three instruments will acquire critical information during entry, descent and landing on the lunar surface, which will inform the design of future landers including the next human lunar lander.
The Stereo Cameras for Lunar Plume-Surface Studies will image the interaction between the lander engine plume as it hits the lunar surface.
The Surface and Exosphere Alterations by Landers payload will monitor how the landing affects the lunar exosphere.
The Navigation Doppler Lidar for Precise Velocity and Range Sensing payload will make precise velocity and ranging measurements during the descent that will help develop precision landing capabilities for future landers.
There also are two technology demonstrations selected to fly.
The Solar Cell Demonstration Platform for Enabling Long-Term Lunar Surface Power will demonstrate advanced solar arrays for longer mission duration.
The Lunar Node 1 Navigation Demonstrator will demonstrate a navigational beacon to assist with geolocation for lunar orbiting spacecraft and landers.
NASA facilities across the nation are developing the payloads, including Ames Research Center in California’s Silicon Valley; Glenn Research Center in Cleveland; Goddard Space Flight Center in Greenbelt, Maryland; Johnson Space Center in Houston; Langley Research Center in Hampton, Virginia; and Marshall Space Flight Center in Huntsville, Alabama.
Nine U.S. companies, selected through NASA’s Commercial Lunar Payload Services (CLPS) in November 2018, currently are developing landers to deliver NASA payloads to the Moon’s surface. As CLPS providers, they are pre-authorized to compete on individual delivery orders.
NASA also released the Lunar Surface Instrument and Technology Payload (LSITP) call in October 2018 soliciting proposals for science instrument and technology investigations. The final LSITP proposals are due Feb. 27 and awards are expected to be made this spring.
“Once we have awarded the first CLPS mission task order later this spring, we will then select the specific payloads from the internal-NASA and LSITP calls to fly on that mission. Subsequent missions will fly other NASA instrument and technology development packages in addition to commercial payloads,” said Clarke.
Commercial lunar payload delivery services for small payloads, and developing lunar landers for large payloads, to conduct more research on the Moon’s surface is a vital step ahead of a human return.
As the next major step to return astronauts to the Moon under Space Policy Directive-1, NASA has announced plans to work with American companies to design and develop new reusable systems for astronauts to land on the lunar surface. The agency is planning to test new human-class landers on the Moon beginning in 2024, with the goal of sending crew to the surface by 2028.
Researchers from NASA and the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, report that streams of meteoroids striking the Moon infuse the thin lunar atmosphere with a short-lived water vapor.
The findings will help scientists understand the history of lunar water — a potential resource for sustaining long term operations on the Moon and human exploration of deep space. Models had predicted that meteoroid impacts could release water from the Moon as a vapor, but scientists hadn’t yet observed the phenomenon.
Now, the team has found dozens of these events in data collected by NASA’s Lunar Atmosphere and Dust Environment Explorer. LADEE was a robotic mission that orbited the Moon to gather detailed information about the structure and composition of the thin lunar atmosphere, and determine whether dust is lofted into the lunar sky.
“We traced most of these events to known meteoroid streams, but the really surprising part is that we also found evidence of four meteoroid streams that were previously undiscovered,” said Mehdi Benna of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the University of Maryland Baltimore County. Benna is the lead author of the study, published in Nature Geosciences.
The newly identified meteoroid streams, observed by LADEE, occurred on Jan. 9, April 2, April 5, and April 9, 2014.
There’s evidence that the Moon has water (H2O) and hydroxyl (OH), a more reactive relative of H2O. But debates continue about the origins of the water, whether it is widely distributed and how much might be present.
“The Moon doesn’t have significant amounts of H2O or OH in its atmosphere most of the time,” said Richard Elphic, the LADEE project scientist at NASA’s Ames Research Center in California’s Silicon Valley. “But when the Moon passed through one of these meteoroid streams, enough vapor was ejected for us to detect it. And then, when the event was over, the H2O or OH went away.”
Lunar scientists often use the term “water” to refer to both H2O and OH. Figuring out how much H2O and how much OH are present is something future Moon missions might address.
This infographic shows the lunar water cycle based on the new observations from the Neutral Mass Spectrometer on board the LADEE spacecraft. At the lunar surface, a dry layer overlays a hydrated layer. Water is liberated by shock waves from meteoroid impacts. The liberated water either escapes to space or is redeposited elsewhere on the Moon. Some water is created by chemical reactions between the solar wind and the surface or delivered to the Moon by the meteoroids themselves. However, in order to sustain the water loss from meteoroid impacts, the hydrated layer requires replenishment from a deeper ancient water reservoir.

LADEE, which was built and managed by NASA’s Ames Research Center in California’s Silicon Valley, detected the vapor using its Neutral Mass Spectrometer, an instrument built by Goddard. The mission orbited the Moon from October 2013 to April 2014 and gathered detailed information about the structure and composition of the lunar atmosphere, or more correctly, the “exosphere” – a faint envelope of gases around the Moon.
To release water, the meteoroids had to penetrate at least 3 inches (8 centimeters) below the surface. Underneath this bone-dry top layer lies a thin transition layer, then a hydrated layer, where water molecules likely stick to bits of soil and rock, called regolith.
From the measurements of water in the exosphere, the researchers calculated that the hydrated layer has a water concentration of about 200 to 500 parts per million, or about 0.02 to 0.05 percent by weight. This concentration is much drier than the driest terrestrial soil, and is consistent with earlier studies. It is so dry that one would need to process more than a metric ton of regolith in order to collect 16 ounces of water.
Because the material on the lunar surface is fluffy, even a meteoroid that’s a fraction of an inch (5 millimeters) across can penetrate far enough to release a puff of vapor. With each impact, a small shock wave fans out and ejects water from the surrounding area.
When a stream of meteoroids rains down on the lunar surface, the liberated water will enter the exosphere and spread through it. About two-thirds of that vapor escapes into space, but about one-third lands back on the surface of the Moon.
These findings could help explain the deposits of ice in cold traps in the dark reaches of craters near the poles. Most of the known water on the Moon is located in cold traps, where temperatures are so low that water vapor and other volatiles that encounter the surface will remain stable for a very long time, perhaps up to several billion years. Meteoroid strikes can transport water both into and out of cold traps.
The team ruled out the possibility that all of the water detected came from the meteoroids themselves.
“We know that some of the water must be coming from the Moon, because the mass of water being released is greater than the water mass within the meteoroids coming in,” said the second author of the paper, Dana Hurley of the Johns Hopkins University Applied Physics Laboratory.
The analysis indicates that meteoroid impacts release water faster than it can be produced from reactions that occur when the solar wind hits the lunar surface.
“The water being lost is likely ancient, either dating back to the formation of the Moon or deposited early in its history,” said Benna.
NASA is leading a sustainable return to the Moon with commercial and international partners to expand human presence in space and bring back new knowledge and opportunities.

Earlier in August, a team from the 10th Special Forces Group (Airborne) won the 2020 Best Warrior Competition that was organized by the 1st Special Forces Command (1st SFC).
The 10th SFG team was comprised of a Special Forces Engineer Sergeant (18C), who competed in the NCO category, and a Nodal Network Systems Operator-Maintainer (25N) who competed in the junior enlisted category. Both soldiers came from the 2nd Battalion of the Group and had previously won a unit-level competition that qualified them from the big event.
Because of the Coronavirus pandemic, the competition was conducted virtually. Teams from across the command competed in a series of events.
The competition was broken up into a series of several events that assessed soldiers holistically. Competing teams had to take the Army Physical Fitness Test (APFT), shoot the M4 qualification test, write an essay, take a military knowledge exam, complete a 12-mile ruck march, and answer questions for an oral military board. Attention to detail throughout the competition was paramount, and teams were even graded on the correctness of their uniforms.
The Engineer Sergeant explained that some of the tasks were unfamiliar even for a Special Forces operator.
“I have very little background in Army doctrine and the reasons they do certain things,” he said in a press release. “It got me out of my comfort zone and now I have a greater base of knowledge than I did prior to this.”
The junior member of the 10th SFG team added that “it was definitely weird for us because you can’t see who you’re competing against. It’s a different feeling for sure and in a competition that really drives me.”
Both soldiers remained anonymous due to the sensitive nature of their job.

1st SFC is responsible for the Army’s Special Forces Groups (there are five active duty, 1st, 3rd, 5th, 7th, and 10th, and two National Guard, 19th and 20th), the 75th Ranger Battalion, the 4th and 8th Psychological Operations Groups, and the 95th Civil Affairs Brigade.
The command sergeant major of 2/10th SFG said that “hands down I’m proud, they represent the battalion very well. This battalion has a blue-collar work ethic, so if they’re going to do it, they’re going to do it to the best of their ability.”
Green Berets primarily specialize on Unconventional Warfare, Foreign Internal Defence, Direct Action, and Special Reconnaissance. True to their soldier-diplomat nature, they embed with a partner force, which, depending on the situation, might be a guerrilla group or a government army, and work with and through that local force to increase their effectiveness and achieve their mission.

Special Forces soldiers deploy in 12-man Special Operations Detachment Alphas (ODAs). Each ODA is comprised of an officer, warrant officer, operations sergeant, intelligence sergeant, and two weapons, engineer, communications, and medical sergeants. The idea behind the duplicate military occupational specialties is to enable the ODA to split into two, or even more, smaller teams.
The 10th SFG troops had to prepare for the competition while still excelling at their jobs. “Right from the beginning you could tell that they were putting in the effort to study and brush up on warrior tasks,” added their sergeant major. “Ultimately they displayed impressive levels of physical and mental toughness.”
Special Forces teams are often the first in a hot spot because of their unique combinations of combat effectiveness and cultural expertise. They led the campaign against al-Qaida and the Taliban in Afghanistan; they invaded northern Iraq and held numerical superior enemy forces during the 2003 Iraqi invasion; and they were the first in Iraq to stop the Islamic State onslaught.
The military community is huge on rivalry and houses some of the most inventive d*ck measuring contests you can think of. Each branch is currently and forever waging a friendly war with one another that has no signs of stopping — not that we’d want it to.
We hate on each other for various reasons, but at the end of the day — we’re still on the same side.
Now, when Marines think about the men and women of the Air Force, they automatically think of them being hardcore.
We’re kidding. Marines don’t remotely think that and constantly hate on airmen for various reasons.
So check out these six reasons why Marines hate on the Air Force. Shots fired (but all in good fun).
6. Marines have it tougher.
Air Force boot camp is slightly less than eight-weeks long; Marine Corps boot camp, however, is about 13 grueling weeks long. Recruits tend to join the Air Force either because they feel the Corps’ boot camp is too tough, or the Marine recruiters “just weren’t in the office that day” (cough, bullsh*t, cough).
5. The Air Force has the best chow halls in the military. But why? Because they need all their energy to fight fly drones?
That does look glorious, though…
4. Even celebrities who visit airmen wear Marine Corps issue.
Chuck Norris, Bugz Bunny, and Bob Hope are just a few honorary Marines. How many cool celebrities are honorary airmen? Go ahead — name one!
3. They get cute little command coins when they graduate vs. the beloved Eagle, Global, and Anchor after completing the “Crucible.”
Need we say more?
2. Their living conditions are considered five-star compared to the Corps’.
We love the teddy bear and string light additions. It really makes the room pop.
