Unidentified object floating outside station? Sort of...

On the morning of August 19, NASA astronaut Chris Cassidy noticed an unidentified object floating outside the space station, near the Progress cargo vehicle. He called down to Mission Control Houston and took some video of it. Was it a UFO? Not really...Russian ground controllers identified it as an antenna cover from the Zvezda service module.

Wow. Couldn't something like that pose a real problem to the rest of the craft?
How did it get loose anyways.

Space junk is always a threat :/

"From time to time there appear on the face of the earth men of rare and consummate excellence, who dazzle us by their virtue, and whose outstanding qualities shed a stupendous light. Like those extraordinary stars of whose origins we are ignorant, and of whose fate, once they have vanished, we know even less, such men have neither forebears nor descendants: they are the whole of their race."  -- Jean de la Bruyere 1645-1696.

Almost certainly not. Space junk poses a threat because of the huge closing speeds involved in a collision. In this case, as it is in an almost identical orbit with the ISS the closing speed is next to zero. Eventually it will just drift away.

It's not impossible that it could pose a threat to another satellite, but there is much more worrying debris in orbit.

Zvezda has been in orbit for 13 years, experiencing the extreme heat of day and the extreme cold of night every 90 minutes for the entirety of that time. That a non-vital component has worked lose is not really surprising.

Can't they just send something up to bat it away or something? Just kidding.

Actually that's not a bad idea. We studied firing the attitude thrusters to 'blow away' light stuff, but often it just comes back anyway an hour or so later.
