SpaceX this month logged its fifth successful mission to the International Space Station (ISS) and had a hand in yet another historic first: delivering the first 3D printer in space.
SpaceX launched its fifth journey to the ISS and fourth official Commercial Resupply (CRS) mission to the orbiting lab early this week, on Sunday, 21 September 2014 from Launch Complex 40 at Cape Canaveral Air Force Station, Florida.
SpaceX CRS-4 is the fourth of at least 12 missions to the ISS that SpaceX will fly for NASA under the CRS contract. The SpaceX Dragon spacecraft will remain at the ISS for four weeks, returning to Earth in mid-October for a parachute-assisted splashdown off the coast of southern California.
“Dragon is the only operational spacecraft capable of returning a significant amount of supplies back to Earth, including experiments,” according to a SpaceX spokesperson. “Under the CRS contract, SpaceX has restored an American capability to deliver and return significant amounts of cargo, including live plants and animals, to and from the orbiting laboratory.”
Dragon delivered more than 5,000 pounds of supplies and payloads, including materials to support 255 science and research investigations during Expeditions 41 and 42.
This cargo mission includes a number of firsts. For the first time, Dragon carried live mammals (20 rodents) in NASA’s Rodent Research Facility, developed at NASA’s Ames Research Center to study the long-term effects of microgravity on mammalian physiology. SpaceX’s Dragon also delivered the 3-D Printing In Zero-G Technology Demonstration, the first 3D printer ever in space.
This geek loves SpaceX and their passion, drive, and innovation. They are making out of this world research possible.
