It is intended to demonstrate a new nontoxic spacecraft propellant system (methane and oxygen) and an autonomous landing and hazard detection technology.
The Alpha prototype lander was manufactured and assembled at NASA's Johnson Space Center (JSC) and Armadillo Aerospace's facility near Dallas.
[7] 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.
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.
[27] On August 9, 2012, the prototype Morpheus #1 Unit A (Alpha) lander crashed on takeoff, whilst performing its second untethered flight at Kennedy Space Center.
KSC limited the noise vibrations on the lander as it lifts off by designing a mobile launch pad with a built-in flame trench.
[10][44] ALHAT permits the lander to fly to a specified location with high accuracy and to automatically avoid hazards including slopes greater than 5 degrees and boulders taller than 30 cm.
[45] In June 2013 the team remarked on the potential to scale the 500 kg payload lander up to one able to land a habitable module with a crew on places such as the Moon.
[44] ALHAT permits the lander to fly to a specified location with high accuracy and to automatically avoid hazards including slopes greater than 5 degrees and boulders taller than 30 cm.
Software is used in: As of April 2011 the primary focus of the test bed is to demonstrate an integrated propulsion and inertial-based guidance, navigation, and control (GN&C) systems that can fly a lunar descent profile, thereby exercising the Autonomous Landing and Hazard Avoidance Technology (ALHAT), safe landing sensors and closed-loop flight control system.
[74] As can be seen in the photograph, the Kennedy's wide open spaces permit the entire flight path including runway and hazard field to be surrounded by a fire break consisting of a moat filled with water.
The 330 by 330 ft (100 by 100 m) hazard field included five potential landing pads, 311 piles of rocks and 24 craters that mimic an area on the Moon's south pole.
A soft abort terminated the flight when the vehicle exceeded an internally set boundary limit whilst attempting to stabilize itself.
[78] On July 11, 2013, the first tethered flight test of Morpheus vehicle "Bravo" with Autonomous Landing & Hazard Avoidance Technology (ALHAT) laser sensors integrated on top was performed.
On the second attempt there was a good ignition, but during ascent the vehicle translated downrange and exceeded the internally set range safety boundary limit (+/−4 m) for tether tests, triggering an automatic soft abort.
[86] On December 10, 2013, the first free flight of a Morpheus prototype lander was successfully conducted at Kennedy Space Center's Shuttle Landing Facility.
The 54-second test began with the Morpheus lander launching from the ground over a flame trench and ascending approximately 50 feet, then hovering for about 15 seconds.
The vehicle flew its pre-planned trajectory flawlessly, reaching a maximum ascent velocity of 13 m/s, and landing an on its intended target 74 seconds after launch.
[8] On February 14, 2014, and March 3, 2014, hot fire testing of the lander's Roll Control System (RCS) using a variety of short and long pulses was performed at KSC.
[94][95] The multi-center Morpheus Team successfully completed Free Flight 8 at the Kennedy Space Center (KSC) Shuttle Landing Facility (SLF) on Wednesday, March 5, 2014.
The ALHAT Hazard Detection System (HDS) performed well, but identified a safe site just 0.5 m (1.6 ft) outside the conservatively established limits around the center of the landing pad.
The team overcame a few preflight issues, including a failed ignition due to a non-critical temperature exceeding its limit, which was corrected for the successful second attempt.
The ALHAT hardware had been enhanced with new optics that permit the Navigation Doppler Lidar to accurately measure the vehicle's velocity relative to the ground.
[103] On December 15, 2014, the prototype lander soared 800 feet above the north end of the Shuttle Landing Facility at Kennedy Space Center in Florida on free flight test No.
At Kennedy Space Center a small flame trench for ground launches was dug near the hazard field (constructed to test the ALHAT).
As well as the lander electrical batteries for ground power, cranes, load cells and propellant tankers need rolling out to the launch stands.
Commercial partnerships with enterprises such as Jacobs Engineering, Armadillo Aerospace, Draper Labs, and others have augmented the development and operation of many aspects of the project.
[107] Although the liquid oxygen/liquid methane bipropellant mix is considerably easier and safer to handle than hydrazine, the propellants can catch fire and cryogenic fuel tanks and Dewars can explode.
[112] 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.
"Through this test, NASA obtained Level 6 of Technology Readiness Level (TRL) related to the planet landing technology"[113] 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.
