Ariane flight VA248 (French: Ariane vol VA248) was a rocket launch conducted by multinational launch service provider Arianespace.


American telecommunications company AT&T and European satellite operator Eutelsat were the customers for Ariane flight VA248.[1] The flight launched two geostationary satellites, totaling a payload mass of 10,594 kilograms (23,356 pounds).[2][3] AT&T commissioned the launch of its AT&T T-16 communications satellite – originally ordered by satellite television provider DirecTV as the next satellite in its existing fleet prior to the acquisition of the company in 2015.[1][4] The acquisition made AT&T the largest provider of subscription television in the world, with 26 million subscribers in 2015;[5][6] this has since decreased to 22.4 million subscribers in 2019.[7] Eutelsat commissioned the launch of its Eutelsat 7C communications satellite, which provides 49 Ku band transponders for Sub-Saharan African digital television stations and capacity for several hundred channels in the region.[8][9] The satellite also has optical communication capabilities for use by government services in Europe, the Middle East, and Central Asia, with a steerable beam capable of reaching areas visible to the satellite in its geostationary orbit above Africa.[10] Eutelsat 7C was manufactured by Maxar Technologies and its design, intended for a lifespan of 15 years, is based on the SSL 1300 satellite bus.[11] Weighing 3,400 kilograms (7,500 pounds), the satellite uses electric propulsion for orbit maintenance, which reduces the satellite's launch mass.[11][12] Eutelsat 7C arrived at the Guiana Space Center on 31 May.[13] AT&T T-16 and Eutelsat 7C were the 601st and 602nd satellites launched by Arianespace.[14]

The Ariane 5 ECA launch vehicle rolled out to Kourou's ELA-3 launch pad on 19 June 2019.[15] It lifted off at 21:43:00 Coordinated Universal Time (UTC) on 20 June 2019, approximately two minutes before sunset during a launch window that lasted an hour and 47 minutes.[16][17][18] The rocket's boosters and EPC first stage were expended in under nine minutes, while the ESC-A upper stage's HM7B engines burned for sixteen minutes;[19] the EPC first stage intentionally crashed in the Gulf of Guinea, off the west coast of Africa.[19] Following the conclusion of the burn, AT&T T-16 separated from the ESC-A at 22:11 UTC, 28 minutes after the start of the flight, followed by the Eutelsat 7C's separation six minutes later, at 22:17 UTC.[3][12] The flight lasted 34 minutes,[3] and placed the satellites into a geostationary transfer orbit from which they will eventually be placed into geostationary orbit through their own propulsion.[20] Eutelsat 7C was placed at 7° east, a position which allowed the satellite to serve its intended markets in Africa, Central Asia, Europe, and the Middle East.[8][10] Eutelsat 7C will continue in-orbit testing until the end of 2019, after which it will become fully operational.[21] Ariane flight VA248 was the 104th launch of an Ariane 5 launch vehicle, and the 71st launch of its ECA variant.[22][23] It was also the fifth launch conducted by Arianespace in 2019.[23]
