NASA is counting down to the launch of its Artemis 1 mission to the moon at 1:04 a.m. EST (0604 GMT) on Nov. 16. You can watch the launch live in the video stream above.

The rollout will start Monday at 12:01 a.m. EDT (0401 GMT) and take the Artemis 1 stack on a 4-mile (6.4 kilometers), 8-to-12-hour trek from KSC's Vehicle Assembly Building (VAB) to Pad 39B. You can watch parts of it live here at Space.com, courtesy of NASA; the agency will apparently livestream views from the VAB when rollout begins and from Pad 39B when the SLS and Orion get there. This will be the second rollout for Artemis 1. The first occurred in mid-March, when SLS and Orion emerged from the VAB around sunset before an audience of hundreds, backdropped by...

The third attempt at a final prelaunch test for NASA's Artemis I mega moon rocket began Thursday morning, but the trial hit some snags and ended prematurely at 5:10 p.m. ET. The agency will host a news conference on Friday to share updates and next steps for the test. The mission team had been attempting to fuel the 322-foot-tall (98-meter-tall) Artemis I rocket stack, including NASA's Space Launch System and Orion spacecraft, at Kennedy Space Center in Florida, but encountered a number of delays.

NASA's second attempt to fuel its Artemis 1 moon mission megarocket hit another snag on Monday (April 4) due to a valve issue on ground equipment. A stuck vent valve high up on the mobile launcher structure supporting the Artemis 1's Space Launch System rocket at Launch Pad 39B of NASA's Kennedy Space Center forced NASA to scrub the Artemis 1 test after fueling began on Monday, agency officials said. The valve is use to relieve pressure from the rocket's core stage during fueling. Monday's fueling attempt was NASA's second try to fill the core stage of Artemis 1's 322-foot-tall...
