Spacewalking astronauts replace antenna after debris scare

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.
12 things you never knew about Galileo satellites

Europe’s Galileo satellite navigation system is providing the world’s most precise positioning services, but the satellites at its heart are surprisingly compact, and dependent on many different technologies to keep running. Here are 12 things you probably didn’t know about them:
Galileo launch postponed

Due to unavailability of a downrange tracking station, Arianespace has taken the decision to postpone the fueling of Galileo's three stage Soyuz launcher. The VS26 Soyuz launch vehicle and the satellites are in a stable and safe condition.
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.
