Its first stage successfully returned from space and set down on a landing platform floating in the Pacific Ocean as the second stage went on to deploy the satellites in orbit.
SpaceX completed its third launch with a previously used first stage booster October 11, carrying a geostationary satellite for customers EchoStar and SES. The rocket used on this flight included a first stage that was previously flown for a Space Station resupply mission in February, and then recovered and refurbished by SpaceX.
A SpaceX Falcon 9 rocket lifted off from Cape Canaveral Wednesday evening on the EchoStar 105/SES-11 mission. The satellite will cover the Americas, including Alaska, Hawaii, Mexico and the Caribbean, from the 105 degrees west orbital location. It was the third time SpaceX has used a "flight-proven" first stage on a mission.
This is already the 15th successful launch of the carrier rocket in 2017 and the second in a week. Another launch helped loft the BulgariaSat-1 spacecraft on June 23. The California-based company first re-flew one of those landed boosters on March 30, during the launch of the SES-10 communications satellite.
EchoStar's half of the satellite is designed for television broadcast, government and enterprise communications. Titanium grid fins, as seen during the Iridium-2 mission earlier this year, are a feature of the Block 5 goal, but the main modification is expected to be the addition of a new sort of heat shield to cover the octaweb structure that holds the vehicle's 9 Merlin 1D rocket engines.
SES-11 is a broadcast-focused payload that replaces the 13-year old AMC-18, and is created to support high definition and Ultra-HD television.
