... asteroid deflection in a different light!

Take Part

In 2026 the European Space Agency's spacecraft HERA will have completed its two years journey to the Didymos system. Its objectives are to investigate the binary asteroid and to measure in great detail the outcome of NASA's DART mission kinetic impactor test. Hera will provide unprecedented information on the kinetic impactor asteroid deflection technique.

Waiting for all of this to happen, in the "Planetary Defence Challenge", you are tasked to develop a methodology able to give preliminary insights on a (virtual) kinetic impactor mission, based on ground measurements. The light curves of a binary asteroid system are observed from the Earth before and after a kinetic impact. Can you learn from the data the real effect of the deflection effort?

Start by learning more about the challenge and the data.

This competition is organized by ESA's Advanced Concepts Team (ACT) in partnership with the H2020 MCSA ETN Stardust-R as part of the Andrea Milani Challenge.

Experts from Stardust-R are available for interactions via the competition discussion page.
