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

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.

Ghost Riders in the Sky is what Firefly Aerospace and NASA are calling a mission set to launch to the moon this week, delivering 10 science and technology instruments onto the lunar surface.

Firefly Aerospace launches Blue Ghost Lunar Lander on a SpaceX rocket, embarking on a 45-day journey to conduct scientific experiments on the moon.

RAC is Aegis’ first payload to the moon’s surface, and it will operate for 14 days. For Stephanie Murphy, who took over the company from her father and built it into its current form, it was an "unmatched buzz" to see the launch from Cape Canaveral, Florida.

Firefly's Blue Ghost Mission 1 has taken a significant leap toward the Moon, with its successful second engine burn positioning the spacecraft for lunar orbit. NASA’s science and technology instruments aboard Firefly’s Blue Ghost Mission 1 are making steady progress toward the Moon.
