fjo3 shares a report from the Washington Post: The International Space Station had to fire thrusters from a docked spacecraft last month to avoid a piece of debris that has been circling the globe for the nearly 18 years since the Chinese government blasted apart one of its own satellites in a weapons test. The evasive maneuver was the second in just six days for the space station, which has four NASA astronauts and three Russian cosmonauts aboard. That is the shortest interval ever between such actions, illustrating the slowly worsening problem of space junk in orbit. Debris is an increasingly vexing issue not only for NASA, but also for companies such as SpaceX and OneWeb seeking to protect the thousands of small satellites they send into space to provide high-speed internet. The debris cloud from China’s 2007 destruction of the Fengyun 1C satellite remains one of the most persistent threats in orbit, with about 3,500 fragments still posing collision risks to spacecraft. Since 2020, the ISS has performed 15 debris-avoidance maneuvers.
The evasive maneuver was performed after a Space Force warning. According to the report, Space Force now tracks over 47,200 objects in orbit, issuing approximately 23 daily collision warnings — up from just six per day five years ago.
