Andrea Milani Challenge

UPDATE: The challenge is now open!

The 'Andrea Milani' Challenge

A worldwide competition on parameter determination for asteroids and space debris

Summer 2021

The European Innovative Training Network Stardust-Reloaded has the pleasure to announce the launch of the “Andrea Milani” Challenge, in honour of the great Italian mathematician and astronomer Prof Andrea Milani who passed away suddenly in 2018. He was an early pioneer in asteroid impact monitoring, and a stalwart in the field of celestial mechanics. He was involved in several ESA missions including BepiColombo and JUICE, and with the creation of SpaceDys and the near Earth asteroid database NeoDys. The competitions will be evolving through ESA´s platform Kelvins, as part of our agreement with ESA´s Advanced Concept Team, a partner of Stardust-R.

Stardust-Reloaded and ESA ACT team invite students and researchers from all around the world to compete in two challenges within the fields of asteroids and space debris monitoring and detection. These topics are part of a larger effort by Stardust-R, and others; critical for the long-term safety of our planet from space threats as well as the long term sustainability of the human presence into space.

Challenge Description

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

For the asteroid deflection challenge, please visit the webpage:

For participating in the space debris challenge, please visit the webpage:

STAGE I: Stage I is open to everyone in the world.Teams have 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 will be assessed by a single numerical metric.

All participating teams  will be given a score (updated after each submission) at the Kelvins leaderboard. The teams with the best score will be invited to participate in the Stardust-R Global Virtual Workshop on Space Traffic Management and Resilient Space Environment in September 2021, where there will be a special Andrea Milani Challenge session devoted to the presentation and discussion of the solutions.

STAGE II: Teams composed only by students will participate in stage II of the competion, 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 will be invited to present their approach to a panel of experts at the workshop. One winner for each category will be announced at the conference closing ceremonies, based on their technical approach and innovation in solving the challenge.
