Space junk that ESA demo mission intends to de-orbit as been struck by another piece of space junk
In a strange bit of irony, an abandoned payload adapter from a mission launched a decade ago that a European Space Agency (ESA) mission was planning on capturing and de-orbiting has been hit by another piece of space junk, creating additional bits debris around it.
The adapter is a conical-shaped leftover, roughly 250 pounds (113 kg) in mass, from a 2013 Vega launch that sent a small fleet of satellites into orbit. Space tracking systems found new objects nearby the adapter, which ESA learned about on Aug. 10. The objects are likely space debris from a “hypervelocity impact of a small, untracked object” that smacked into the payload adapter, the agency said. We may never know if the crashing object was natural or artificial, given it didn’t appear in tracking systems.
The ESA mission, dubbed Clearspace-1, intends to launch in 2026 and use four grappling arms to grasp the payload adapter, after which both shall be sent to burn up in the atmosphere. Its goal is to demonstrate technology for removing space junk. This event, creating extra debris pieces around the payload adaptor, puts a kink on that mission while also underlining the need for such technology.
Mission engineers now have three years to figure out what, if anything, they need to do to deal with the extra debris. The good news so far is that it appears the payload adapter remains intact, its orbit has not changed, and the surrounding debris appears small enough to pose “negligible” risk.
