Masten Space Systems was an aerospace manufacturer startup company in Mojave, California (formerly in Santa Clara, California) that was developing a line of vertical takeoff, vertical landing (VTVL) rockets, initially for uncrewed research sub-orbital spaceflights and eventually intended to support robotic orbital spaceflight launches.

In 2020, NASA awarded Masten a contract for a lunar lander mission; NASA was to pay Masten US$75.9 million for Masten to build and launch a lander called XL-1 to take NASA and other customer payloads to the south pole of the Moon. Masten Mission One would have been Masten's first space flight; it was scheduled for launch in November 2023.^[1]

The company filed for Chapter 11 bankruptcy in July 2022,^[2] and was later acquired by Astrobotic Technology in September 2022.^[3]
