(credit: Trevor Mahlmann) It's actually happening. NASA is finally set to launch its massive Space Launch System rocket, and barring catastrophe, the Orion spacecraft is going to fly to the Moon and back. The space agency's final pre-launch preparations for this Artemis I mission are going so well, in fact, that NASA now plans to roll the rocket to Launch Pad 39B as soon as Tuesday, August 16, at 9 pm ET (01:00 UTC Wednesday).
