Replay: NASA will update us all on its Artemis 1 moon mission today. How to follow it online.

Update for 6 pm ET: NASA is now targeting no earlier than May to launch the Artemis 1 moon mission on the first flight of the Space Launch System megarocket. Read our full story.


NASA will give an update about its Artemis 1 moon mission today (Feb. 24) and you can tune in online.

Artemis 1 will be the first-ever launch of NASA's new Space Launch System (SLS) megarocket. The mission will send an uncrewed Orion capsule around the moon, to ensure that the SLS-Orion duo is ready to carry astronauts for the agency's Artemis program of lunar exploration.

Artemis 1 is currently expected to roll out to its launch pad at NASA's Kennedy Space Center (KSC) in Florida in mid-March ahead of a launch in April or May. We'll learn about the latest mission progress and timelines during Thursday's press conference, which will start at 1:30 p.m. EST (1830 GMT). You can listen to it live here at Space.com, courtesy of NASA, or directly via the agency (opens in new tab).

Participating in the call will be:

  • Tom Whitmeyer, deputy associate administrator for exploration systems development at NASA headquarters in Washington
  • Mike Bolger, Exploration Ground Systems program manager at KSC
  • Mike Sarafin, Artemis 1 mission manager at NASA headquarters

The mid-March rollout of the SLS-Orion stack will allow NASA to conduct a crucial prelaunch test.

"This final test, known as the wet dress rehearsal, will run the launch team through operations to load propellant into the rocket's tanks and conduct a full launch countdown. Following a successful rehearsal, NASA will roll the rocket stack back into the Vehicle Assembly Building for final checks and set an official target date for launch," agency officials wrote in an update Tuesday (opens in new tab) (Feb. 22).

"Through Artemis missions, NASA will land the first woman and the first person of color on the surface of the moon, paving the way for a long-term lunar presence and serving as a stepping stone on the way to Mars," they added.
