SpaceX’s Falcon 9 rocket stands ready for a 7:16 p.m. EST liftoff from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Watch now on NASA+ or the agency’s website

Aboard Falcon 9 is Intuitive Machines’ lunar lander named Athena, which is carrying NASA science and technology instruments to the Moon as part of the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign. IM-2 will also carry several payloads from other non-NASA customers. 

Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron are predicting greater than 95% chance of favorable weather conditions for launch.  

Here’s a look at some of today’s countdown and ascent milestones. All times are approximate:
