For its third launch photo editor of the year, the Falcon 9 SpaceX successfully launched two electric satellites built by Boeing, one for Eutelsat and the second for Asia Broadcast. This dual launch comes just less than twenty days after the launch of DSCOVR and twenty two days before that of TürkmenÄlem. An ambitious mission and a high rate that enhance the commercial attractiveness of SpaceX.
Launch after launch, SpaceX is emerging as the main competitor of Arianespace. In 2014, the European company achieved 11 launches, including five Ariane 5 ECA that launched 10 satellites into geostationary transfer orbit (GTO) against six launches for SpaceX and three satellites into GTO. Nevertheless, she is on a par with SpaceX in the commercial market. photo editor The two rivals have each won 9 of the 18 contracts for telecommunications satellites in geostationary orbit launches signed last year.
SpaceX asserts itself and becomes an alternative launch credible solution and especially the commercial offer of Arianespace. The European company has built its trade policy on dual launch and impeccable service: a heavy load (10 tonnes in GTO), launches photo editor on time, a very precise orbit acquisition and a wide range of launchers meeting all the needs of operators and satellite manufacturers. The American firm, it makes the low cost of the bet (with currently a limit to 4.85 tonnes in GTO) and reusability to impose itself on the commercial market.
Both power satellites, Eutelsat and ABS 115 West B-3A. On the same appearance, they differ in the number of transponders they board: 32 C-band and 14 Ku-band for Eutelsat 115 West B, and 24 C-band and 24 Ku-band for ABS-3A. Boeing Electric propulsion imposes month of transfer to orbit
In the night from Sunday to Monday, SpaceX again marked a point against Arianespace. A Falcon 9 launch vehicle photo editor lifted off from Cape Canaveral to 4 h 50 Paris time and made a double launch which helped to set supersynchronous transfer orbit (410 x 63000 km) two power satellites, one for Eutelsat (Eutelsat 115 West B) and the second for Asia Broadcast (ABS-3A). This new success SpaceX is also a good trading blow for Boeing, the manufacturer of these two telecom power satellites (platform 702SP). This electric powered platform was designed to simultaneously launch two satellites to reduce costs.
Finally, if SpaceX successfully its mission, the satellite Eutelsat 115 West B and ABS-3A is just beginning. Indeed, six to eight months they will need to reach their orbital position in geostationary orbit, a trip that chemical-powered satellites travel in just a few days.
Note that for this mission, all the performance of the launcher was dedicated to the launch of two satellites of 2,200 kg (Eutelsat 115 West B) and 2,000 kg (ABS-3A). SpaceX therefore did not attempt to recover the first stage of its launch vehicle. photo editor
