Test Flight · Sun-Synchronous Orbit
Second test flight of the Isar Spectrum launch vehicle. This launch will carry 5 cubesats and 1 non-separable experiment as part of European Space Agency (ESA)'s “Boost!” program: * CyBEEsat (TU Berlin) * TriSat-S (University of Maribor) * Platform 6 (EnduroSat) * FramSat-1 (NTNU) * SpaceTeamSat1 (TU Wien Space Team) * Let It Go (Dcubed, non-separable experiment)
What it put in orbit
Passes over you For a few days after launch the 6 satellites fly one behind another, a “train” you can see as a line of moving stars. When will it cross your sky?
