A SpaceX mission set to lift off overnight marks a first for Firefly Aerospace under NASA's plans to build up American companies to support its lunar goals.

Firefly Aerospace's Blue Ghost lunar lander launched at 1:11 a.m. Wednesday from NASA's Kennedy Space Center in Florida on the SpaceX rocket before separating an hour later. The lunar lander — part of a mission known as Blue Ghost Mission 1 or Ghost Riders in the Sky — will spend 45 days in orbit and 14 days on the surface of the moon.

The spacecraft built and operated by Texas-based Firefly Aerospace launched in the early Monday hours from Florida aboard a SpaceX rocket.
