SpaceX, NASA and Intuitive Machines are planning to launch the NASA CLPS IM-1 lunar lander Odysseus tonight at Kennedy Space Center from Pad LC-39A at 12:57 AM EST. The launch, aboard a Falcon 9 rocket, aims to be the first successful American soft-landing on the lunar surface since Apollo 17 in 1972.

Following the launch, the booster being used for the mission will return to land at LZ-1 in Cape Canaveral, and will herald its return with a sonic boom that will be heard across the Space Coast region.

That’s the first of two launches scheduled for Valentine’s Day. The second is USSF-124, launching from SpaceX’s pad SLC-40 Cape Canaveral Space Force Station. This mission’s launch window extends from 5:30 PM until 10:00 PM EST and is also an RTLS mission.

Launch Weather Outlook: NASA CLPS IM-1

First, the early launch, NASA CLPS/IM-1: the 45th Weather Squadron of the US Space Force is predicting a low Probability of Violation for the planned liftoff at 12:57 AM EST: only 5%. That means they are expecting a 95% chance of acceptable conditions for liftoff.

NASA CLPS IM-1 Trajectory

As is customary for most missions beyond Earth orbit, NASA CLPS IM-1 will take an easterly path from KSC after liftoff. People watching the launch in person should be able to see the reentry burn and if in the right place, the landing burn of Falcon 9 as it returns to land.

Launch Weather Outlook: USSF-124

The weather gets even better for the second planned launch of the day, according to the 45th Weather Wing: less than a 5% Probability of Violation, meaning a 95+% chance of acceptable weather conditions at liftoff.

USSF-124 Trajectory

Also eastward. Again, in-person launch viewers should be able to see the reentry burn and if in the right place, the landing burn of Falcon 9 as it returns to land.

SpaceX has not announced which landing pad they will utilize for this launch — either LZ-2, or perhaps the Falcon 9 used for LM-1 will be removed in time for USSF-124. Either way, to launch viewers off of the base itself, the landing will be in the same general direction.
