Ariane flight VA253 (French: vol Ariane VA253) was a successful rocket launch conducted by multinational launch service provider Arianespace on August 15th, 2020.[1]
Payload[edit]
American satellite operator Intelsat and Japanese Broadcasting Satellite System Corporation (B-SAT) are the customers for Ariane flight VA253.[2][3]
Galaxy 30 is a communications satellite built by Northrop Grumman Innovation Systems (formerly Orbital ATK) on the GEOStar-2 platform for Intelsat. It has C-band, Ku-band, Ka-band payloads, as well as a WAAS payload for a mass of 3,325 kilograms (7,330 lb).[4] Built in satellite manufacturing facility in Dulles, Virginia, it will primarily serve video markets in North America.[5] As per Intelsat/Arianespace contract announced in January 2018,[6]
Galaxy 30 will share the upper berth of the Ariane 5 ECA rocket with MEV-2, which is Northrop Grumman second satellite servicing vehicle, identical to MEV-1. With a mass of 2,326 kilograms (5,128 lb), it will begin a five-year mission to extend lifetime of Intelsat 10-02.[7] MEV-2 received FCC authorization on 25 March 2020.[8]
BSAT-4b is the second communications satellite of the fourth generation B-SAT, built by SSL (company) on its SSL 1300 platform. It has 24 Ku-band transponders and mass of 3,520 kilograms (7,760 lb).[9]
Flight[edit]
Ariane flight VA253 was planned to launch in June 2020,[10] however, launch campaign activities were significantly affected by the COVID-19 pandemic. To prevent the spread of the epidemic in French Guiana and protect Centre Spatial Guyanais employees, all launch activities were suspended on 16 March 2020.[11][12][13] Operations for Vega flight VV16 and Ariane 5 flight VA253 could not resume until 28 April 2020.[14][15][16] VA253 activities were listed among the top priorities at the reopening of the Guiana Space Center on 11 May 2020.[17] The launch is scheduled for end of July 2020.[15][18][19] The flight should place the satellites into a geostationary transfer orbit from which they will eventually be placed into geostationary orbit through their own propulsion. The flight was again aborted on 28 July 2020, due to a "red" warning in the system, resulting from a sensor problem related to LH2 tank on the core stage. The flight was launched on 15 August 2020 at 22:04 UTC.[1]
