NASA’s Mars Perseverance Rover Provides Front-Row Seat to Landing, First Audio Recording of Red Planet
New video from NASA’s Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface of Mars. A microphone on the rover also has provided the first audio recording of sounds from Mars.
From the moment of parachute inflation, the camera system covers the entirety of the descent process, showing some of the rover’s intense ride to Mars’ Jezero Crater. The footage from high-definition cameras aboard the spacecraft starts 7 miles (11 kilometers) above the surface, showing the supersonic deployment of the most massive parachute ever sent to another world, and ends with the rover’s touchdown in the crater.

Here’s What We Know About Planetary Protection On China’s Tianwen-1 Mars Mission
This spring, China will attempt its first Mars landing. But in anticipation of that milestone, scientists are wondering whether the Tianwen-1 rover may carry Earthly contamination with it to the surface.
Because scientists have high hopes of someday discovering traces of life on Mars, spacecraft that will land on the planet are kept as immaculately free of Earthly life as possible. These days, that means a complicated cleaning procedure throughout the spacecraft’s assembly and frequent testing for spores, an inactive form of bacteria that are particularly hardy.

Imaging Space Debris in High Resolution
Litter is not only a problem on Earth. According to NASA, there are currently millions of pieces of space junk in the range of altitudes from 200 to 2,000 kilometers above the Earth’s surface, which is known as low Earth orbit (LEO). Most of the junk is comprised of objects created by humans, like pieces of old spacecraft or defunct satellites. This space debris can reach speeds of up to 18,000 miles per hour, posing a major danger to the 2,612 satellites that currently operate at LEO. Without effective tools for tracking space debris, parts of LEO may even become too hazardous for satellites.

For Military Superiority in Space, Start with Safety
The U.S. military has worked in space for decades, providing GPS to the masses and bouncing combat messages through satellites to troops around the world. In some ways, though, the Space Force feels like it’s starting from scratch.
The Space Force was created to ward off Chinese anti-satellite weapons and Russian satellites stalking U.S. spy systems across the cosmos, among other concerns. Still, officials are looking for ways to keep space safe and maintain an upper hand while the Pentagon learns how to treat space as it does air, land, and sea.

Space Enthusiasts In Japan Ready To Launch Their Own Satellite
Interest in commercial aerospace is growing among amateurs in Japan, with enthusiasts assembling rockets and satellites by trial and error. As the space business grows around the world, amateur builders and launchers, including office workers and students, are challenging the idea that outer space is the sole domain of professionals.
“Let’s disassemble it and replace the component,” says a voice at a small workshop in Tokyo’s Edogawa Ward. Spread out on a table are several components. In the center is a satellite, one side of which measures about 10 cm. The person who suggests replacing the part is working away in a sweatsuit.

NASA Postpones Second SLS Green Run Test
Just days after NASA said it was ready to perform a second static-fire test of the Space Launch System core stage, the agency announced Feb. 22 that the test would be delayed because of a valve problem.
NASA said it was postponing the Green Run static-fire test, which had been scheduled for Feb. 25, after discovering a problem with one of eight valves called “prevalves” in the core stage that supply propellant to the stage’s four RS-25 main engines. The valve, which supplies liquid oxygen, was “not working properly,” NASA said in a statement, but didn’t elaborate on the problem.

Experts Ponder Nuclear Rockets To Send Humans To Mars
When NASA’s Perseverance rover touched down on the Martian surface last week, humans cheered from the confines of planet Earth.
But if the space agency or others hope to leave and send astronauts to Mars, experts say they need to consider a technology that was studied decades ago but never fully developed: nuclear-powered rockets.
“If we decide to send humans to Mars, nuclear propulsion is likely to be central to that journey,” says Roger Myers, an independent aerospace consultant and co-chair of a panel convened by the National Academies to study nuclear propulsion.

Testing Proves Its Worth With Successful Mars Parachute Deployment
Test. Test again. Test again. Testing spacecraft components prior to flight is vital for a successful mission.
Rarely do you get a do-over with a spacecraft after it launches, especially those bound for another planet. You need to do everything possible to get it right the first time.
Three successful sounding rocket missions from NASA’s Wallops Flight Facility in Virginia in 2017 and 2018 to test a supersonic parachute proved their worth with the successful landing of the Perseverance mission on the Red Planet.

Bloomberg Assails NASA Space Launch System With Misconceptions And Faulty Logic
The editorial board at Bloomberg News launched a nonsensical attack on NASA’s human spaceflight program last week. It was full of dubious assertions about alternatives to the Space Launch System, the first deep-space rocket NASA has built for human transport since Saturn V lofted Apollo missions to the Moon half a century ago.
I don’t normally call attention to arguments that I think are wrong, but since Bloomberg’s screed was explicitly aimed at the Biden administration, I thought it might be useful to rebut some of the questionable claims advanced by the editorial board.

Op-ed | Why the National Space Council matters
NASA marked another milestone last week with the successful landing of the Perseverance rover on Mars. Perseverance is now the fifth and most technologically advanced rover to reach the surface of the red planet.
Perseverance’s main objectives are to search Mars for signs of ancient life and collect soil samples that will eventually be brought back to Earth. Yet the mission will also have broader implications for space policy. The discovery of ancient life, for example, could influence policy regarding planetary protection, future human missions, and international norms for exploration. The fact that Perseverance could be joined by a Chinese rover later this year highlights the growing space competition between the U.S. and strategic rivals.

‘Who Was In NASA 901?’: Remembering Project Gemini’s Worst Day, 55 Years On
At 7:41 a.m. CST on 28 February 1966—55 years ago on Sunday—a pair of sleek T-38 Talon jets took off from Ellington Field, not far from the Manned Spacecraft Center (MSC) in Houston, Texas, bound for Lambert Field in St. Louis, Miss. Aboard the lead jet, tailnumbered “NASA 901”, were astronauts Elliot See and Charlie Bassett, prime crew for the forthcoming Gemini IX mission, targeted to launch in May of that year.And following them in the second T-38, tailnumbered “NASA 907”, were their backups, Tom Stafford and Gene Cernan. Flight rules forbade a member of a prime crew to fly with his counterpart on the backup crew, lest an accident wipe out the entire specialty for one seat on the mission. Tragically, those rules held firm on the fateful morning of 28 February 1966.
