Liftoff of Falcon 9 carrying ABS 3A & Eutelsat 115 West B, from LC-40 at Cape Canaveral

On March 1, 2015, SpaceX’s Falcon 9 rocket delivered the ABS 3A and EUTELSAT 115 West B all-electric satellites to a supersynchronous transfer orbit.

Marking Falcon 9’s sixteenth launch and the vehicle’s most voluminous payload to date, the liftoff occurred at 10:50pm EST from SpaceX’s Launch Complex 40 at Cape Canaveral Air Force Station, Fla.

SpaceX ABS/Eutelsat-1 Mission

Approximately three minutes into flight, the first stage engines cut off and the first and second stages separated. Shortly thereafter, the second stage’s single Merlin Vacuum engine ignited to complete a five-minute burn. Twenty-five minutes into flight the engine restarted to complete a one-minute burn to bring the satellites to orbit.

ABS 3A satellite

Thirty minutes into flight, the ABS 3A satellite deployed into a supersynchronous transfer orbit followed by EUTELSAT 115 West B approximately five minutes later.

The satellites will now fire their thrusters to reach geosynchronous orbits. As the world’s first all-electric propulsion satellites, they carry no liquid propellant – rather, they reach orbit entirely via a lighter and more efficient electric propulsion system. ABS 3A will be located at 3° West and will connect the Americas, Europe, Africa and the Middle East.  EUTELSAT 115 West B will be located at 114.9° West and will provide coverage from Alaska and Canada to South America.

SpaceX’s next launch is targeted for approximately three weeks from now, from Cape Canaveral, Fla.
