Rocketdyne SSME thrust chamber under test in 1970 or 1971. (Rocketdyne)
Early in 1971, the cooled thrust chamber was ready, aiming at NASA’s requirements: 415,000 pounds of thrust, 14,670 ft/sec in exhaust velocity, 3000 psi in pressure. The last test achieved full thrust for only 0.45 seconds. It nevertheless bettered these numbers substantially, delivering 505,700 pounds, 14,990 ft/sec, and 3172 psi. This was twice the rated thrust of the XLR-129, and 60 ft/sec greater in its exhaust velocity.
NASA’s Evolutionary Xenon Thruster (NEXT) project has completed the longest duration test for a Space propulsion system (48,000 hours/5 1/2 years). This look inside the thrusters discharge chamber shows how it works.
The multi-center Morpheus Team successfully completed Free Flight7 (FF7) at the Kennedy Space Center (KSC) Shuttle Landing Facility (SLF) on Minday, February 10, 2014. FF7, the 5th free flight of the Bravo vehicle, flew to 467 feet (142m), altitude and then traversed 637 feet (194m) in 30 seconds before landing in the hazard field. Initial data indicated a nominal flight meeting all test objectives. The vehicle flew its pre-planned trajectory flawlessly, reaching a max ascent velocity of 13 m/s, and landing with no appreciable deviation from its intended target 74 seconds after launch. The Morpheus Team again demonstrated engineering and operational excellence, relying upon training, discipline and experience to ensure today’s success.

NASA’s Jet Propulsion Laboratory tested its G-FOLD divert algorithm experimental landing system on September 20, 2013 at the Mohave Air & Space Port in Mojave, Calif. G-FOLD, which stands for Fuel Optimal Large Divert Guidance Algorithm, enables a rocket to select an alternate landing site, autonomously. The test was performed aboard a Masten Xombie rocket.
Morpheus lander in the third diMENSION!
NASA’s Morpheus Team successfully completed Free Flight 5 (FF5) at the KSC Shuttle Landing Facility (SLF). FF5, the 3rd free flight of Morpheus’ Bravo vehicle, was higher and faster than all previous flights. Bravo vehicle flew its pre-planned trajectory flawlessly, ascending quickly to 57 m (187 ft), traversing 47 m (154 ft) while descending, then landing ~11 inches from intended target in the Hazard Field about a minute after launch. The Morpheus Team again demonstrated engineering and operational excellence, relying upon training, experience, and discipline to ensure a successful FF5.
