On Sunday morning, SpaceX successfully launched and landed a Falcon 9 rocket carrying a Dragon spacecraft loaded with over 5000 pounds of supplies and experiments bound for the International Space Station.Cargo Resupply mission 10 (CRS-10) was a historic one for a number of reasons. Primarily because it marked Kennedy Space Center's return to being an active spaceport after nearly six years of no launches following the end of space shuttle programs in 2011, but also because it marked SpaceX's first return to the ISS after it had a Falcon 9 explode on the launch pad during a pre-launch test last September.As part of a 12-launch contract between SpaceX and NASA, CRS-10 was originally slated to fly in November, but following the explosion was pushed back until today. It follows on the heels of SpaceX's first launch since the explosion, which flew from Vandenberg Air Force Base in California last month carrying 10 communications satellites into orbit. Unlike last month's launch, however, SpaceX recovered the first stage of the Falcon 9 rocket today, which touched down at Landing Zone 1 at Cape Canaveral Air Force Station, just down the coast from Kennedy.In the two days leading up to the launch, the mood at Kennedy was one of cautious optimism, marked by a noticeable excitement about the grand re-opening of launch complex 39A.Read the rest at Motherboard.
