X-Prize Cup: The Northrop Grumman Lunar Lander Challenge is a competition funded by NASA's Centennial Challenges program. The competition offers a series of prizes for teams that launch a vertical takeoff/vertical landing (VTVL) rocket
that achieves the vehicle to move between the surface of the Moon and its orbit. The multi-level competition is conducted by the X-Prize Foundation, with sponsorship from the Northrop Grumman Corporation. It has been held annually at the X-Prize Cup.

NG LLC: The X-Prize Cup was canceled for 2008, the Lunar Lander Challenge was held separately by Northrop Grumman.
Winners NG LLC, Level 1: First prize: Armadillo Aerospace 24 October 2008.  Second prize: Masten Space Systems 7 October 2009
Winners NG LLC, Level 2: First prize: Masten Space Systems 30 October 2009.  Second prize: Armadillo Aerospace 12 September 2009

CRuSR: Masten Space Systems of California, and Armadillo Aerospace of Texas were awarded contracts by NASA to provide flight opportunities for engineers, technologists and scientific researchers to fly technology payloads into space. It is part of NASA’s Commercial Reusable Suborbital Research (CRuSR) program.

Flight test version


    
 

  Xaero-B
2016, June -- Masten Space Systems showed off two new rockets that can hover, make precision landings, and be used over and over again.
The 15-foot-tall reusable rockets are called Xodiac and XaeroB. Masten’s rockets are suborbital, meaning they can reach space, but can’t get high enough to reach orbit. Xodiac and XaeroB are essentially just more efficient and more reliable versions of Masten’s other rockets Xaero, Xoie, and Xombie. Both have the new engine Cyclops-AL-3.

  Morpheus Lunar Lander


     

Morpheus's new 19 kN engine permitted NASA to design a larger vehicle than its parent, a copy of Armadillo Aerospace's Quad (Pixel) rocket lander.
The engine was upgraded again in 2013 finally reaching 24 kN (Isp 321 sec).
