There were two challenge problems, each was numerical in nature on the topic of parameter estimation of either space debris or an asteroid. The problems pulled primarily from the fields of mathematics, physics and astrodynamics, computer science, and aerospace engineering.

STAGE I: Stage I was open to everyone in the world.Teams had to solve a complex numerical problem on parameter estimation for either space debris or asteroids, within a given time window. The solution to the problem was assessed by a single numerical metric.
All participating teams were given a score (updated after each submission) at the Kelvins leaderboard. The teams with the best score were invited to participate in the Stardust-R Global Virtual Workshop on Space Traffic Management and Resilient Space Environment in September 2021, where there was a special Andrea Milani Challenge session devoted to the presentation and discussion of the solutions.
STAGE II: Teams composed only by students participated in stage II of the competition, leading also to participate in the special Andrea Milani Challenge session of the Stardust-R Global Virtual Workshop on Space Traffic Management and Resilient Space Environment. The top 3 student teams for each competition were invited to present their approach to a panel of experts at the workshop. One winner for each category was announced at the conference closing ceremonies, based on their technical approach and innovation in solving the challenge.
