Moon Express, Inc., a privately funded lunar resources company, unveiled its “MX-1” lunar lander spacecraft today as a breakthrough robotic space vehicle capable of a multitude of applications including delivering scientific and commercial payloads to the Moon at a fraction of the cost of conventional approaches. The spacecraft design is being unveiled today at the closing session of Autodesk University in Las Vegas in front of an audience of over 10,000 attendees.
The MX-1 synthesizes proprietary robotic technologies, advanced micro-avionics, and a unique toroidal structure to produce a “green” robotic spacecraft that is powered by sunlight and uses hydrogen peroxide as rocket fuel. Hydrogen peroxide (H2O2) is an oxygen enriched water compound commonly found in nature and biological systems. With the recent discovery of water on the Moon, the MX-1 has a potential source of rocket fuel on the lunar surface, a scenario that would be a game changer in the economics of lunar resources and solar system exploration.
“The spacecraft rockets use a high test version of the consumer level hydrogen peroxide widely available in drug stores”, said Tim Pickens, Chief Propulsion Engineer at Moon Express and former propulsion lead for SpaceShipOne. “We’re developing three new rocket engines at our Propulsion Development and Test Facilities in Huntsville and benefiting greatly from new advances in digital 3D design and fabrication tools.”
The main MX-1 rocket engine is a dual mode bi-propellant system that also uses kerosene as an after burner to give the spacecraft the punch to break out of Earth orbit, accelerate to faster than a bullet, travel a million miles to beyond the Moon, and come back to break to zero velocity using its outboard thrusters as it touches the lunar surface. The spacecraft is designed to ride to Earth orbit on low cost secondary payload opportunities aboard commercial launchers like the SpaceX Falcon 9 that are radically reducing the cost of access to space.
About the size of a large coffee table, the MX-1 is a completely self-contained single stage spacecraft that can reach the surface of the Moon from a geosynchronous transfer orbit (GTO) commonly used to place communications satellites above the Earth. It is also designed to be a flexible spacecraft platform that can support a number of applications including serving as a flexible, agile upper stage for existing launch systems enabling Earth orbit cubesat deployment, satellite servicing, and “space tug” applications such as cleaning up space debris.
