Last May, SpaceX's Dragon capsule became the first commercial spacecraft in history to visit the International Space Station. This morning, the private spaceflight company will attempt to do it again.
SpaceX's second cargo delivery mission to humanity's outpost in space is set to lift off at 10:10 ET, atop the company's Falcon 9 rocket. Watch it live, with coverage beginning at 8:30 ET, here on io9 (see below) — or via SpaceX's webcast page beginning at 9:30 ET.
The resupply mission is the second in SpaceX's 12-mission, $1.6-billion deal with NASA, and a crucial proving step on the company's path to delivering humans to and from the ISS. Every successful cargo delivery instills a little more confidence in the burgeoning private spaceflight sector, and adds another feather to SpaceX's cap of credibility. We're talking about crucial proof-of-concept — not just for crewed missions to and from the ISS, but to the Moon, asteroids, and Mars.
