1/ We are monitoring a close approach event involving IRAS (13777), the decommissioned space telescope launched in 1983, and GGSE-4 (2828), an experimental US payload launched in 1967. (IRAS image credit: NASA)pic.twitter.com/13RtuaOAHb

3/ These numbers are especially alarming considering the size of IRAS at 3.6m x 3.24m x 2.05m. The combined size of both objects increases the computed probability of a collision, which remains near 1 in 100.
4/ Events like this highlight the need for responsible, timely deorbiting of satellites for space sustainability moving forward. We will continue to monitor this event through the coming days and provide updates as available.
Wasn't the Space Force created to prevent things like this?!?pic.twitter.com/bMbLEcgo6A
Not at all. Space Force will just be doing things the Air Force was already in charge of - reconnaissance, weather monitoring, and communications.https://www.npr.org/2019/12/21/790492010/trump-created-the-space-force-heres-what-it-will-do …
Any amateur astronomers near Pittsburgh want to try to observe this? Happens around dusk on Wednesday.
I work in downtown Pittsburgh. I get home at 6! Perfect timing! I’ll try to check it out
I hope they don't hit, and also really REALLY hope we have telescopes pointed at the potential collision point. If things go horribly wrong, we should at least have a record of it.
That's a pretty solid life lesson. "At least if it goes to shit, we'll have it on video."
What is MSR and the red elipses?
That is one of our three tracking radars, Midland Space Radar in Texas. The red ellipses show its field of view.
