After successfully returning to flight on Jan. 14th, SpaceX will make its next launch from Cape Canaveral no earlier than Jan. 30th. With this mission from a new pad at Launch Complex 39A, SpaceX will loft theĀ EchoStar 23 communications satellite to geostationary transfer orbit.
This is a heavy satellite, weighing 5.5 metric tons, and getting it out to about 40,000km from the surface of the Earth will require pretty much all of the lift capacity of SpaceX’s Falcon 9 rocket. This would leave almost no propellant for the Falcon 9 rocket to fire its engines to slow down, make a controlled descent through the Earth’s atmosphere, and attempt a difficult landing on a drone ship.
On Saturday, in response to a question on Twitter, SpaceX founder and chief executive Elon Musk confirmed that the upcoming EchoStar launch will therefore indeed be expendable. “Future flights will go on Falcon Heavy or the upgraded Falcon 9,” he added.
