Most rockets make spacecraft travel faster... But the goal of a lunar lander 'descent engine' is to slow the vehicle so astronauts can land safely... Reducing risk and advancing technology, for a reliable robust rocket engine; that could enable America's next moon landing...
The Common Extensible Cryogenic Engine, or CECE, is fueled by a mixture of liquid oxygen and liquid hydrogen chilled to sub zero...
(see test below)
"The latest engine configuration incorporates a new injector design and propellant feed system that carefully manages the pressure, temperature and flow of propellants...
The technology developed from this effort will help engineers successfully design future cryogenic engines to meet the throttling requirements of the Constellation Program's Altair lunar lander." more.
About: NASA has invested in CECE technology since 2005 as part of the Propulsion and Cryogenics Advanced Development project at Glenn. The project is funded by the Exploration Technology Development Program in NASA's Exploration Systems Mission Directorate.
