Highlight Lecture: Sustainability and Safety of Large Satellite Constellations from the Starlink Perspective Looking Forward

There is a bright and exciting future for humanity ahead – and space is fundamental to that future. To achieve this, space safety must be done right. We encourage every operator to not only share ephemeris data proactively the same way Starlink already does, but to also adopt the high standards of space safety that SpaceX and Starlink use every day.
