NASA announced on June 5 that it awarded a contract to Northrop Grumman to begin work on a habitation module for the lunar Gateway, nearly a year after the agency announced its intent to sole-source that module to the company.
NASA said it issued a contract to Northrop Grumman valued at $187 million for the Habitation and Logistics Outpost (HALO) module, which will serve as an initial habitat for crews visiting the lunar Gateway. The module, described by NASA as the size of a small studio apartment, will be able to support short stays by crews arriving on Orion spacecraft.
The contract does not cover all the work needed for HALO. Instead, the award announced June 5 funds design of the module through a preliminary design review late this year. The contract also allows Northrop Grumman to issue subcontracts for hardware with long lead times. A contract modification will come later to fund full development and testing of HALO.
The only surprise about the contract is the time it took NASA to formally issue it. In a July 2019 procurement filing, NASA announced its intent to issue a sole-source award to Northrop Grumman after concluding that the company was the only one who would have a module ready to support the agency’s plans to return humans to the moon by 2024.
Northrop’s module is based on its Cygnus spacecraft used to transport cargo to the International Space Station. “The success of our Cygnus spacecraft and its active production line helps to enable Northrop Grumman to deliver the HALO module,” said Steve Krein, vice president of civil and commercial satellites at Northrop Grumman, in a company statement.
Northrop, though, will make significant modifications to the Cygnus design for HALO, such as installing several docking ports to accommodate Orion spacecraft or other Gateway elements. It will also have new command and control systems and an enhanced life support system to support visiting crews.
“This contract award is another significant milestone in our plan to build robust and sustainable lunar operations,” said NASA Administrator Jim Bridenstine in an agency statement. “The Gateway is a key component of NASA’s long-term Artemis architecture and the HALO capability furthers our plans for human exploration at the moon in preparation for future human missions to Mars.”
