Ariane flight VA253 (Template:Lang-fr) is a planned rocket launch conducted by multinational launch service provider Arianespace.

Payload

American satellite operator Intelsat and Japanese Broadcasting Satellite System Corporation (B-SAT) are the customers for Ariane flight VA253.[1][2] 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 tonnes (3.665 tons).[3] Built in satellite manufacturing facility in Dulles, Virginia, it will primarily serve video markets in North America.[4] As per Intelsat/Arianespace contract announced in January 2018,[5] 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 tonnes (2.564 tons), it will begin a five-year mission to extend lifetime of Intelsat 10-02.[6] MEV-2 received FCC authorization on 25 March 2020.[7] 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 3.52 tonnes (3.88 tons).[8]

Flight

Ariane flight VA253 was planned to launch in June 2020,[9] 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.[10][11][12] Operations for Vega flight VV16 and Ariane 5 flight VA253 could not resume until 28 April 2020.[13][14][15] VA253 activities were listed among the top priorities at the reopening of the Guiana Space Center on 11 May 2020.[16] The launch is currently scheduled for end of July 2020.[14][17][18] 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 July 28, 2020, due to a "red" warning in the system.
