SpaceX launches 15th mission of the year on previously flown rocket booster


Eventually, SpaceX hopes to not only increase the pace at which it can launch, but also turn around rockets for reuse within 24 hours, so the more in can launch multiple rockets in the same week, the better for its long-term plan. Successfully placed in orbit, the dual-mission satellite will be shared by Colorado-based EchoStar and SES, a Luxembourg company. In this case, the Falcon 9 that's being used for this mission flew a resupply mission to the International Space Station (ISS) in February of this year.

SpaceX is planning to launch a Falcon 9 rocket Wednesday night from Kennedy Space Center in Florida. EchoStar-105/SES-11 separated from the rocket's upper stage roughly 36 minutes into the mission as planned. During the last launch, the Elon Musk-led company sent its 12th Falcon 9 booster of 2017. The rocket's first stage successfully landed moments later on a SpaceX drone ship in the Atlantic Ocean. Another launch helped loft the BulgariaSat-1 spacecraft on June 23.

"Yet another successful landing of a Falcon 9 first stage", he added. Musk, SpaceX's chief executive officer, has championed reusability- once derided as a insane idea-to lower launch costs and win a growing roster of customers. Thus, this part of the rocket can go into space for the third time. EchoStar 105/SES-11 replaces Ku-band capacity for AMC-15 and C-band capacity for AMC-18 at SES' well-established 105 degrees West orbital slot. 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.
