Europe's first meteorological satellite in polar orbit, Metop-A , has been successfully deorbited by Europe's meteorological satellite agency, EUMETSAT , with support from Airbus .
Starting immediately, the satellite will spiral downward in progressively lower orbits until it disintegrates upon re-entering the Earth's atmosphere, a process that is expected to end within the next 25 years, in accordance with international standards on space debris mitigation.
NASA details intent to replace the International Space Station with a commercial space station by
NASA’s auditing body, the Office of Audits, has produced a report detailing the agency’s commitment to replacing the International Space Station (ISS) with one or more commercial space stations once the orbiting lab is retired.
This audit basically details the current costs of maintenance and operation of the ISS, and also explains why it thinks that there will still be an essential need for a research facility that can provide a test bed for prolonged human exposure to space, as well as for development and
ESA's Solar Orbiter sails safely past Earth • The Register
ESA's Solar Orbiter has completed its flyby of Earth, collecting science data as it did so, and appears to be headed back into deep space without any close encounters with orbiting debris.
The flyby took place on 26 and 27 November, with the spacecraft whizzing past the planet at 12km/s at an expected altitude of around 450km at its closest approach.

Dec 2 (Reuters) - Two NASA astronauts were set to embark on a spacewalk on Thursday to replace a faulty antenna on the International Space Station (ISS), after a 48-hour delay prompted by an orbital debris alert later deemed to be of no concern.

Nothing unseemly or untoward, to be sure. Just friendly reminders that orbiting garbage is starting to clog up Earth's satellite lanes like a halo of space waste.
Geha says we might want to do something about it — like take out the trash. Growing pockets of space debris already have an effect on scientific space missions, she noted, and pose a safety threat to manned missions.
Space Force officer: orbiting satellites have become pawns in geopolitical chess games - Space
What is happening in space is a "natural consequence" of how military powers historically behave as they try to gain a leg up on adversaries, Saltzman said Nov. 29 during a Mitchell Institute online event. "These are dynamic times in the space security environment," he said.

International Space Station shines in gorgeous fly-around photos by Crew Dragon astronauts | Space
On Nov. 8, the Crew Dragon capsule Endeavour, carrying the four astronauts of SpaceX's Crew-2 mission, departed the orbiting lab after a 6.5-month stay.
The fly-around helped test Endeavour's navigation sensors. The Crew-2 astronauts also snapped photos during the maneuver, allowing ISS managers to see portions of the station that are usually out of view.
