Project Morpheus Test Flight - NASA

Project Morpheus was a NASA project that began in 2010 to develop a vertical takeoff and vertical landing (VTVL) test vehicle called the Morpheus Lander. It is intended to demonstrate a new nontoxic spacecraft propellant system (methane and oxygen) and an autonomous landing and hazard detection technology. The prototype planetary lander is capable of autonomous flight, including vertical takeoff and landings. The vehicles are NASA-designed robotic landers that will be able to land and take off with 1,100 pounds (500 kg) of cargo on the Moon. The prospect is an engine that runs reliably on propellants that are not only cheaper and safer here on Earth, but could also be potentially manufactured on the Moon and Mars.Show more

The Alpha prototype lander was manufactured and assembled at NASA's Johnson Space Center (JSC) and Armadillo Aerospace's facility near Dallas. The prototype lander is a "spacecraft" that is about 12 ft (3.7 m) in diameter, weighs approximately 2,400 lb (1,100 kg) and consists of four silver spherical propellant tanks topped by avionics boxes and a web of wires.

The project is trying out cost and time saving "lean development" engineering practices. Other project activities include appropriate ground operations, flight operations, range safety and the instigation of software development procedures. Landing pads and control centers were also constructed. From the project start in July 2010, about $14 million was spent on materials in the following 4 years; so the Morpheus project is considered lean and low-cost for NASA. In 2012 the project employed 25 full-time team members, and 60 students. At any one time an average of 40 people worked on the project. Project Morpheus devised and used streamlined processes and practices. The Morpheus Lander's last flight was in December 2014. As there were no funds for further flights the lander was returned to JSC in February 2015. Six formal documents were produced by the project. At the end of project review on March 12, 2015, it was estimated that $50 million had been saved by the lean development methods, minimising documentation, and buying parts from Home Depot, MSC Industrial Direct, and W. W. Grainger.

The Morpheus prototype liquid oxygen and methane (LOx/Methane) propulsion system demonstrated advantages in performance, simplicity, reliability, and reusability. LOx/Methane provides new capabilities to use propellants that are manufactured on the Mars surface for ascent return and to integrate with power and life support systems. It was determined that Lox/Methane is extensible to human spacecraft for many transportation elements of a Mars architecture. The propellants provide significant advantages for reliable ignition in a space vacuum, and for reliable safing or purging of spacecraft. "Through this test, NASA obtained Level 6 of Technology Readiness Level (TRL) related to the planet landing technology"

The Morpheus lander flight demonstrations led to the proposal to use LOx/Methane for a Discovery Program mission, named Moon Aging Regolith Experiment (MARE) to land a science payload for the Southwest Research Institute on the lunar surface. This mission's lander is called NAVIS (NASA Autonomous Vehicle for In-situ Science).

The technology developed is also being applied to the Nova-C lunar lander, proposed to land on the Moon in early 2022.
