NASA and the Government of Japan Formalize Gateway Partnership for Artemis Program
NASA and the Government of Japan have finalized an agreement for the lunar Gateway, an orbiting outpost that commercial and international partners will build together. This agreement strengthens the broad effort by the United States to engage international partners in sustainable lunar exploration as part of the Artemis program and to demonstrate the technologies needed for human missions to Mars.
Under this agreement, Japan will provide several capabilities for the Gateway’s International Habitation module (I-Hab), which will provide the heart of Gateway life support capabilities and additional space where crew will live, work, and conduct research during Artemis missions. The Japan Aerospace Exploration Agency’s (JAXA) planned contributions include I-Hab’s environmental control and life support system, batteries, thermal control, and imagery components, which will be integrated into the module by the European Space Agency (ESA) prior to launch. These capabilities are critical for sustained Gateway operations during crewed and uncrewed time periods.
Under an arrangement with Northrop Grumman, Japan also will provide batteries for the Gateway’s Habitation and Logistics Outpost (HALO), the initial crew cabin for astronauts visiting the Gateway. Additionally, Japan is investigating enhancements to its HTV-X cargo resupply spacecraft, which could result in its use for Gateway logistics resupply.
The agreement also marks NASA’s intent to provide crew opportunities for Japanese astronauts to the Gateway, which will be determined following additional discussions, and documented in a future arrangement.
Approximately one-sixth the size of the International Space Station, the Gateway will serve as a rendezvous point for astronauts traveling to lunar orbit aboard NASA’s Orion spacecraft and Space Launch System rocket prior to transit to low-lunar orbit and the surface of the Moon. From the Gateway, NASA and its partners will use this lunar vantage point as a springboard for robotic and human expeditions to the Moon, and on to Mars.
NASA astronauts will board a commercially developed lander for the final leg of the journey to the lunar surface, and the agency has contracted with U.S. industry to develop the first two Gateway components, the Power and Propulsion Element (PPE) and the HALO, as well as the logistics resupply for Gateway.
