"As a result of these tests, NASA engineers have learned a great deal about different configurations for LOX-methane propulsion systems," said David Stephenson, Marshall's project manager for the Radial Segmented Launch Vehicle.
The benefits of LOX-methane engines, Stephenson
said, stem from their strong performance in supporting missions with heavy payloads.
"Compared to engines powered by traditional storable hypergolic liquid fuels," he
said, "LOX-methane engines have additional capabilities in supporting a large spacecraft's descent and landing on a planetary surface."
