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.
Two versions of a Curiosity selfie: narrow and wide

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.

Ensuring a steady supply of technical and scientific expertise for American industry and innovation has been a national priority since about 1957 when the Soviet Union launched its first Sputnik. Today, however, with the increasingly rapid pace of high technology, the need to attract young people to the field of advanced technical manufacturing has become even more critical. To meet that need, t US Senators urge Biden Admin to toughen response to incidents in space

The moon has no core dynamo magnetic field, but spacecraft detect numerous strong localized magnetic fields in the crust of the moon. Many of these magnetic anomalies are antipodal to large impact basins.
