    Today we are proud to announce the completion of the newest radar in our network, Kiwi Space Radar! Read the full press release here:

    We've summarized the IRAS / GGSE 4 event and our final assessment of it in our latest blog post:

    To all our new followers: welcome! We track satellites and space debris in low Earth orbit, providing services to help prevent collisions and enable a safer operating environment for all. View and search through our full 14,000 object catalog here:

    We will continue to monitor the space environment for these types of close approaches and provide updates when we see high risk scenarios.

    We are pleased to report that in the first several radar passes of the two objects after the close approach, we see no evidence of new debris. This event has served to highlight the collision risks caused by derelict satellites in LEO.

    Thankfully our latest data following the event shows no evidence of new debris. To be sure, we will perform a further assessment upon the next pass of both objects over Kiwi Space Radar occurring later tonight.

    Final update prior to close approach: 47 meter predicted miss distance, w/ increased separation in the cross-track direction. Next scheduled radar passes for both objects to occur approximately two hours after the event.

    5/ Though it is still unlikely that these objects will collide, we have tasked our radars to schedule longer duration tracking on both objects following the event to search for evidence of any new debris (and hopefully not find any!)

    4/ Adjusting our calculations to account for larger object sizes (by increasing our combined Hard Body Radius from 5m to 10m), this yields an updated collision probability closer to 1 in 20.

    3/ Since we learned that GGSE 4 has a deployed 18m boom and we do not know which direction it is facing relative to IRAS, this changes the assumptions used in computing collision risk.

    2/ The 12m total miss distance has components of: 11m radially 0m in-track 5m cross-track We can visualize this conjunction geometry from the top-down and side-on views of the event at TCA:

    1/ Our latest update this morning for IRAS / GGSE 4 shows a 12m miss distance, with a Probability of Collision (Pc) back to 1 in 100. Here is a plot of our last five days worth of miss distance updates on this event:

    Our latest data on the IRAS / GGSE 4 event shows potential miss distances of 13-87 meters, with a lowered collision probability currently at 1 in 1000. Time of closest approach remains at 2020-01-29 23:39:35.707 UTC

    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.

    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.

    2/ On Jan 29 at 23:39:35 UTC, these two objects will pass close by one another at a relative velocity of 14.7 km/s (900km directly above Pittsburgh, PA). Our latest metrics on the event show a predicted miss distance of between 15-30 meters.

    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)
