Spacewalking astronauts replace antenna after debris scare
Thursday, 02 December 2021 16:26
Spacewalking astronauts replaced a broken antenna outside the International Space Station on Thursday after getting NASA's all-clear for orbiting debris.
U.S. astronauts Tom Marshburn and Kayla Barron were supposed to complete the job Tuesday, but NASA delayed the spacewalk because of potentially threatening space junk. NASA later determined the astronauts were safe to go out, despite a slightly increased risk of a punctured suit from satellite wreckage.

Two versions of a Curiosity selfie: narrow and wide
Thursday, 02 December 2021 13:49
NASA's Curiosity Mars rover took this 360-degree selfie using the Mars Hand Lens Imager, or MAHLI, at the end of its robotic arm. The selfie comprises 81 individual images taken on Nov. 20, 2021—the 3,303rd Martian day, or sol, of the mission.
The rock structure behind the rover is "Greenheugh Pediment"; the hill that is middle distance on the right, is "Rafael Navarro Mountain." Curiosity is headed toward "Maria Gordon Notch," the U-shaped opening behind the rover to the left.

A one-way phone call from Mars

This November, ESA's Mars Express spacecraft carried out a series of experimental communication tests with the Chinese (CNSA) Zhurong Mars rover. Mars Express successfully caught data sent up 'in the blind' by the rover and relayed them to Earth where they were forwarded to the Zhurong team in China.
13:07 CET, 7 November, Utopia Planitia. The Zhurong rover, commanded by the Tianwen-1 orbiter, points its radio up at the Martian sky. Any minute now, ESA's Mars Express will begin to pass overhead. Zhurong starts transmitting a signal up into space. It has no way of knowing if its message is being received.
Landers and rovers on Mars gather data that help scientists answer fundamental questions about the geology, atmosphere, surface environment, history of water and potential for life on the Red Planet.
To get these insights to Earth, they first transmit the data up to spacecraft in orbit around Mars. These orbiters then use their much larger, more powerful transmitters to 'relay' the data across space to Earth.
"Normally, an orbiter like ESA's Mars Express first sends down a hail signal to a rover as a 'hello,'" says James Godfrey, Mars Express Spacecraft Operations Manager.
AFRL selects 10 universities for satellite program

The Pentagon suggests that China tested a fractional orbital bombardment system (FOBS) earlier this year. According to US military observers, China's alleged new orbital hypersonic glide vehicle weapon poses a huge challenge to the Pentagon since the US does not have active countermeasures to these arms.
