After a series of delays and false starts, the historic SpaceX mission to the International Space Station is set to launch this morning. Liftoff is scheduled for 3:44AM ET, or 8:44AM BST, and if all goes to plan SpaceX's unmanned Dragon capsule will become the first privately-owned craft to dock with the ISS early on Friday morning. It's worth noting that we've gotten this far before and ended up disappointed by a last-minute abort, but we have a good feeling this time around. You can watch the launch online over at NASA TV — coverage has already started, and there's less than an hour to go. NASA will also be streaming a post-launch news conference at 5:15AM ET / 10:15AM BST.
