Russia Launching Compact Advanced Satellite (CAS500-1) Along With Numerous International Commercial Payloads

Primary Korea Aerospace Research Institute payload CAS500-1 is sharing a ride to SSO (497.8km) with spacecraft from 17 nations aboard Soyuz-2.1a utilizing Fregat upper stage March 20 from Baikonur Cosmodrome. CAS500-1 contains a state-of-the-art Earth imaging sensor capable of resolving 0.5m (panchromatic) / 2m (color). This rideshare is slated to be the first commercial mission organized by GK Launch Services, a partnership between Glavkosmos (subsidiary of Roscosmos) and International Space Company Kosmotras. Notable secondary payloads include Astroscale of Japan End-Of-Life-Service (ELSA-d) debris mitigation technology In-Orbit Demonstration. ELSA-d will showcase decommissioning technique involving 180kg “Chaser” and 20kg “Target” (developed by SSTL) which are to perform maneuvers validating magnetic capture / docking, controlled from National In-orbit Servicing Control Center Facility in the UK. Also from Japan, Axelspace is sending 4 additions to its constellation: GRUS-1B, 1C, 1D, 1E are <100 kg smallsats with 57-km imaging swath with 1.4 day observation frequency in most inhabited latitudes. Mohammed bin Rashid Space Centre is sending pollution monitor DMSAT-1. Gauss of Italy will test cubesat injection with Unisat-7. The first indigenously developed satellite from Tunisia, a constellation precursor, will coincide with the nation’s 65th Independence Day. IAF contest winner Kenya National Park wildlife monitoring 1U SIMBA cubesat is also riding along, as are craft from Saudi Arabia, Israel, Thailand, Canada, Brazil, Germany, Netherlands, Argentina, Hungary, Spain and Slovakia.
