EchoStar XVII or EchoStar 17, also known as Jupiter 1, is an American geostationary high throughput communications satellite which is operated by Hughes Network Systems, a subsidiary of EchoStar.
It is positioned in geostationary orbit at a longitude of 107.1° West, from where it is used for satellite internet access over HughesNet.
EchoStar XVII was built by Space Systems/Loral, and is based on the LS-1300 satellite bus.
It measures  by  by , with  solar arrays which were deployed after launch, and generates a minimum of 16.1 kilowatts of power.
The spacecraft had a mass at liftoff of , and is expected to operate for fifteen years.
It carries sixty  (NATO K band) transponders which is used to cover North America.
EchoStar XVII was launched by Arianespace, using an Ariane 5ECA carrier rocket flying from ELA-3 at Kourou.
The spacecraft was launched at 21:36 UTC on 5 July 2012.
The MSG-3 weather satellite was launched aboard the same rocket, mounted below EchoStar XVII, which was atop a Sylda 5 adaptor.
The launch successfully placed both satellites into a geosynchronous transfer orbit.
EchoStar XVII used its own propulsion system to manoeuvre into a geostationary orbit.
