Team 4 has initiated a Formation Flying working group. After initial videocons earlier this year, we had a videocon on November 21, 2023 in which the group led by Ken Oguri (Purdue University) presented initial results on quasi-periodic motions of a satellite swarm on its Halo orbit around L2. We will have another videocon this year, on December 6, 2023, 20-21 h CET. Get in touch with Ken Oguri, Michael Ireland  and Hendrik Linz in order to get involved, and receive future updates and meeting invitations.
