Lots of discussion on the recent SL-8 R/B v COSMOS 2361 conjunction event. Monte Carlo simulation shows ~80m separation distance at the time of closest approach.

Although neither satellite could maneuver, we show that a slight change to the orbit would've reduced the collision risk dramatically.

Satellite operators and mission stakeholders should join in the discussion to share best practices and lessons learned....let's be proactive! advancedssa.com/workshop/

Orbit updates for both IRAS and GGCE-4 yields a slight REDUCTION in the collision risk, predicted separation distance of 18m (59 feet).

Current collision risk estimate for the IRAS - GGCE-4 conjunction event is ~ 1 chance in 74, with a separation distance of ~56 feet. The collision probability has been above the 1/100 threshold for multiple days. SpaceNav will provide updates on this event throughout the day.

Miss distance distribution via Monte Carlo simulation shows high likelihood of a close crossing later today.
