NASA has selected 11 companies to conduct studies and produce prototypes of human landers for its Artemis lunar exploration program. This effort will help put American astronauts - the first woman and next man - on the Moon's south pole by 2024 and establish sustainable missions by 2028.

"To accelerate our return to the Moon, we are challenging our traditional ways of doing business. We will streamline everything from procurement to partnerships to hardware development and even operations," said Marshall Smith, director for human lunar exploration programs at NASA Headquarters. "Our team is excited to get back to the Moon quickly as possible, and our public/private partnerships to study human landing systems are an important step in that process."

Through Next Space Technologies for Exploration Partnerships (NextSTEP) Appendix E contracts, the selected companies will study and/or develop prototypes during the next six months that reduce schedule risk for the descent, transfer, and refueling elements of a potential human landing system.

NASA's proposed plan is to transport astronauts in a human landing system that includes a transfer element for the journey from the lunar Gateway to low-lunar orbit, a descent element to carry them to the surface, and an ascent element to return to them to the Gateway. The agency also is looking at refueling capabilities to make these systems reusable.

The total award amount for all companies is $45.5 million. As NextSTEP is a public/private partnership program, companies are required to contribute at least 20% of the total project cost. This partnership will reduce costs to taxpayers and encourage early private investments in the lunar economy.

The awardees, from eight states across the country, are:

+ Aerojet Rocketdyne - Canoga Park, California
One transfer vehicle study

+ Blue Origin - Kent, Washington
One descent element study, one transfer vehicle study, and one transfer vehicle prototype

+ Boeing - Houston
One descent element study, two descent element prototypes, one transfer vehicle study, one transfer vehicle prototype, one refueling element study, and one refueling element prototype + Dynetics - Huntsville, Alabama
One descent element study and five descent element prototypes

+ Lockheed Martin - Littleton, Colorado
One descent element study, four descent element prototypes, one transfer vehicle study, and one refueling element study

+ Masten Space Systems - Mojave, California
One descent element prototype

+ Northrop Grumman Innovation Systems - Dulles, Virginia
One descent element study, four descent element prototypes, one refueling element study, and one refueling element prototype

+ OrbitBeyond - Edison, New Jersey
Two refueling element prototypes

+ Sierra Nevada Corporation, Louisville, Colorado, and Madison, Wisconsin One descent element study, one descent element prototype, one transfer vehicle study, one transfer vehicle prototype, and one refueling element study

+ SpaceX - Hawthorne, California
One descent element study

+ SSL - Palo Alto, California
One refueling element study and one refueling element prototype

To expedite the work, NASA is invoking undefinitized contract actions, which allow the agency to authorize partners to start a portion of the work, while negotiations toward contract award continue in parallel.

"We're taking major steps to begin development as quickly as possible, including invoking a NextSTEP option that allows our partners to begin work while we're still negotiating," said Greg Chavers, human landing system formulation manager at NASA's Marshall Space Flight Center in Huntsville, Alabama.

"We're keen to collect early industry feedback about our human landing system requirements, and the undefinitized contract action will help us do that."

NASA gave industry its first heads up in April, with the issuance of a pre-solicitation, of its intention to partner with American companies on the development of an integrated lander. The formal solicitation, to be issued this summer, will provide the requirements for a 2024 human landing, and leave it to U.S. industry to propose innovative concepts, hardware development and integration.

"This new approach doesn't prescribe a specific design or number of elements for the human landing system," Chavers said. "NASA needs the system to get our astronauts on the surface and return them home safely, and we're leaving a lot of the specifics to our commercial partners."

China's Chang'E 4 Mission Discovers New "Secrets" from Far Side of the Moon
Beijing, China (SPX) May 17, 2019
A lunar lander named for the Chinese goddess of the Moon may have lessened the mystery of the far side of the Moon. The fourth probe of Chang'E (CE-4) was the first mission to land on the far side of the Moon, and it has collected new evidence from the largest crater in the solar system, clarifying how the Moon may have evolved. A theory emerged in the 1970s that in the Moon's infancy, an ocean made of magma covered its surface. As the molten ocean began to calm and cool, lighter minerals floated ... read more
