Liftoff had been scheduled for 9:25 a.m. ET on Saturday (March 15), but issues at the launch site have pushed things back.

Firefly Aerospace is planning to launch its “Message in a Booster” mission from Vandenberg Space Force Base this weekend.

Firefly’s lunar landing is NASA’s second CLPS mission. The first took place last year, when Intuitive Machines—another Texas-based private space company—sent its lander to the Moon in February 2024.
