SpaceX’s Dragon spacecraft is making its first cargo trip back to the International Space Station (ISS) since its June attempt ended unexpectedly with the ship exploding itself, and its cargo, in mid-air. Watch today’s launch happen live right here at 4:43 p.m. (EDT). Don’t be late!
The CRS-8 Dragon will be hauling 7,000 pounds worth of supplies up to the ISS. Almost half of that weight is from something incredible: a 12-foot wide space house that astronauts are going to stick to the side of the ISS and then inflate. BEAM (or the Bigelow Expandable Activity Module) is the first test of this particular tech in space. But if all goes well, NASA is already talking about the possibility of dropping similar units on Mars or the Moon to let future colonists live in space.
