Two Satellites Just Avoided a Head on Smash. How Close Did They Come to Disaster?

An analysis of events surrounding the potential collision of the IRAS and GGSE-4 satellites.

On the 29th of January 2020, a company tracking space debris made a prediction that two defunct satellites had a very high probability of a direct head-on collision. But what is a high probability for space collisions? And why do they matter so much? I wrote an article for The Conversation discussing this event, and why this is such an important problem for us to solve. You can read the full article here.

The article was also republished by a variety of news sources. These include:
