Astronauts take shelter in Starliner, other spacecraft after satellite breakup

Nine astronauts aboard the International Space Station sought shelter in their docked return spacecraft, including Boeing's Starliner, following a satellite breakup in low Earth orbit on June 26. The incident was a precautionary measure, and normal operations resumed after about an hour. The satellite breakup was linked to a non-operational Russian spacecraft, Resurs-P1, which released over 100 trackable debris pieces. The astronauts' safety was ensured, and NASA, along with the U.S. military, continues to monitor space debris around the ISS. The incident highlighted concerns about space debris, with over 45,300 trackable objects in orbit. The astronauts on the ISS, including those on the Starliner, are safe, and plans for the Starliner's departure are pending review and testing of its systems. NASA and Boeing are working to ensure a safe return for the astronauts once all necessary precautions are taken.

According to both US Space Command and LEO Labs, the satellite in question was a 6-ton non-functional Russian satellite known as "RESURS-P1": https://en.wikipedia.org/wiki/Resurs-P_No.1

Lots of comments about what a shield would need to look like to protect against this. That’s not the way to think about this in the very near future. The space station and nearly everything in space up until now, is designed with very small mass and tolerances because it’s so expensive to get there in the first place.

As the cost of mass to orbit lowers by orders of magnitude in, likely, the next decade, we can begin seeing spacecraft that are far more durable, redundant and agile. They will have ample propellant to move out of the way and they will have life support systems and failure modes designed to withstand and allow for the repair of small impacts.

This is actually something that happens fairly regularly. Sometimes they even rotate the space station so the smallest frontal area is facing the debris cloud.

What does it take to create a magnetic shield? Given unlimited rare earth metals and such

I recently learned about this company that is designing a satellite to remove debris from space: https://www.starfishspace.com/

What makes the one spacecraft safer than the other?

"This happened, for example, after Russia deliberately destroyed a satellite in November 2021 as part of a surprise anti-satellite test that other countries (including the United States) condemned".

Funny they singled out Russia. From Wikipedia:

"...a few countries (China, India, Russia, and the United States) have successfully shot down their own satellites to demonstrate their ASAT capabilities in a show of force."

> The incident illustrates what NASA officials have been emphasizing about the Boeing Starliner spacecraft, which is more than three weeks into what was expected to be a 10-day Crew Flight Test mission. Starliner is on a test mission with two astronauts and is authorized to leave the ISS in case of emergency. (The other two crewed spacecraft docked to the ISS are a SpaceX Dragon carrying four astronauts, and a Russian Soyuz with three people on board.)

starting to see symptoms of something that could lead to Kessler Syndrome
