With the emergence of "New Space" and the arrival of new actors in the space industry, satellite constellations and mega constellations are becoming a reality. Hundreds and soon thousands of satellites will be orbiting the Earth…
This workshop will tackle various aspects related to constellations and mega constellations:

  • What are they designed for?
  • Which ones are already there, planned, or about to be deployed?
  • How can specific challenges be dealt with regards to flight dynamics, mission design, as well as management and operations, including collision avoidance and disposal?
  • What are consequences on the future space population and the environment?
  • How do astronomers suffer from light pollution caused by mega constellations?
  • How should national and international regulations evolve?

You will find below the final program of the workshop.

Below the program, you will also find a button "S'inscrire" or "Register" that you must follow to receive the Zoom link to connect to the workshop.
The registration deadline is set to May, 26, 23:00 CEST. The link will only be sent to registered participants on May, 27.
