09.09.2021: The final leaderboard has been published. We congratulate the winning team: Vidente! Visit our discussion page for further information on the end of the competition.
02.09.2021: A special session about this competition will be held at the Stardust-R Virtual Workshop about "Space Traffic Management and Resilient Space Environment" between 13-17 of September. The 3 best scoring teams have the opportunity to present their solution to the virtual audience. Participation to the workshop is free of charge but requires registration until (including) 04.09.2021. As the official announcement of the winners will be after this deadline, we would like to encourage you to register already to be on the safe side, in case you are interested. All information regarding the virtual workshop and the registration can be found on the Workshop website.
Every piece of space debris in our orbit was at one point a functional part of a manmade satellite or launcher, before it turned into a hazard. While debris of larger explosions or critical failures typically do not go undetected, more subtle events may jettison debris in a less obvious way, especially for older satellites, which are no longer operational and unmaintained. If not observed and tracked directly, how can we know the origin of a particular piece of space junk when there are already thousands of objects orbiting our planet?
For this challenge, you will investigate several debris pieces who have been observed from groundbased equipment on Earth for some years, but whose origins and exact constitutions are unknown. Given the orbits of some potential culprits, your mission is to determine who is responsible for polluting our orbits.
