Masten Space Systems is a leader in vertical landing technology and EDL test beds with missions to the moon starting in 2021.



Terrestrial vehicles

An Entry, Descent, and Landing (EDL) test bed vehicles with 500+ rocket flights.  Capable of precision station keeping, vertical takeoff and landing, planetary landing trajectories for the Moon and Mars, and allowing customer payloads to fly the vehicle.


Lunar Vehicles

 With missions to the Moon starting in 2021, Masten is busy finalizing the design of the XL-1 lunar lander in partnership with the NASA CATALYST program.  The large lander Xeus is currently in R&D for flights in the mid 2020's.



Masten has propulsion solutions for in-space and small satellite boost applications, with thrusts ranging from less than 1 lbf to 25,000 lbf.  Fuels include cold gas, LOX/IPA, LOX/Methane, and Green Hypergols.

Currently taking payload reservations.


To The Moon And Beyond

Masten Space Systems is delighted to announce that we have been selected for NASA's Commercial Lunar Payload Services (CLPS) contract to deliver payloads to the lunar surface over the next 10 years, paving the way for continued exploration of the Moon and the solar system beyond. Since its inception in 2004, Masten's team has been working diligently to prepare for a lunar mission and are thrilled to be part of this revolutionary period in space entrepreneurship and exploration.

How Will We Get There?

For over a decade, Masten has been a leader in rocket-powered terrestrial flight. Following our 2009 win of the Northrop Grumman Lunar Lander Challenge, we have continued to set records for rocket system reusability and autonomy. Over the last 5 years, Masten has been working closely with NASA on the Lunar CATALYST program to further mature our approach to lander development and to position to execute a lunar mission.

Masten's first lunar vehicle is the XL-1, a spacecraft featuring 2 payload bays and the capacity to deliver 100kg of payload to the lunar surface. The spacecraft will be put on a translunar injection by a larger launch vehicle, and once in lunar orbit, will fire its 4 main engines to slow down and autonomously descend into a soft touchdown at a predetermined location on the lunar surface.

Lunar Objectives

Preliminary lunar missions will be designed to answer questions from the global science community and to develop infrastructure that will contribute to a sustainable lunar presence. Masten plans to continue being a leader in driving an enduring and eventually vibrant lunar economy by accommodating the delivery of a variety of payload types that will perform critical and diverse lunar missions.

Looking Ahead

As we press forward, there is still a lot of work to be done here on Earth before our first lunar touchdown. Masten's next engineering steps include final integration and flight testing of XL-1T, our terrestrial demonstrator vehicle, which serves as a technology precursor for our lunar design. The lunar variant, XL-1, is entering detailed design with a plan to launch by the end of 2021.

Let us deliver your payload to the Moon!
