The Gateway will be an outpost orbiting the Moon that provides vital support for a long-term human return to the lunar surface, as well as a staging point for deep space exploration. It is a critical component of NASA’s Artemis program.

 

The Gateway is a vital part of NASA’s deep space exploration plans, along with the Space Launch System (SLS) rocket, Orion spacecraft, and human landing system that will send astronauts to the Moon. Gaining new experiences on and around the Moon will prepare NASA to send the first humans to Mars in the coming years, and the Gateway will play a vital role in this process. It is a destination for astronaut expeditions and science investigations, as well as a port for deep space transportation such as landers en route to the lunar surface or spacecraft embarking to destinations beyond the Moon.

 

NASA has focused Gateway development on the initial critical elements required to support the 2024 landing – the Power and Propulsion Element, the Habitation and Logistics Outpost (HALO) and logistics capabilities.

 

Power and Propulsion Element

The Power and Propulsion Element (PPE) is a high-power, 60-kilowatt solar electric propulsion spacecraft that will provide power, high-rate communications, attitude control, and orbital transfer capabilities for the Gateway.

 

In May 2019, NASA selected Maxar Technologies of Westminster, Colorado, to develop, build, and support an in-space demonstration of the element.

 

The PPE is managed out of NASA’s Glenn Research Center in Ohio.

 

Habitation and Logistics Outpost (HALO)

The Habitation and Logistics Outpost will be the initial crew cabin for astronauts visiting the Gateway. Its primary purpose is to provide basic life support needs for the visiting astronauts after they arrive in the Orion and prepare for their trip to the lunar surface. It will provide command, control, and data handling capabilities, energy storage and power distribution, thermal control, communications and tracking capabilities, as well as environmental control and life support systems to augment the Orion spacecraft and support crew members. It also will have several docking ports for visiting vehicles and future modules, as well as space for science and stowage.

 

Deep Space Logistics

As astronauts prepare for missions to the lunar surface, they will need deliveries of critical pressurized and unpressurized cargo, science experiments and supplies, such as sample collection materials and other items. In March 2020, NASA announced SpaceX as the first U.S. commercial provider under the Gateway Logistics Services contract to deliver cargo and other supplies to the Gateway. One logistics services delivery is anticipated for each crewed Artemis mission to the Gateway.

 

Initial Launch

In February 2021, NASA selected SpaceX to provide launch services for PPE and HALO. After integration on Earth, the PPE and HALO are targeted to launch together no earlier than November 2024 on a Falcon Heavy rocket from Launch Complex 39A at Kennedy.

 

Gateway's Future

Gateway international partners will provide important contributions to the lunar outpost, comprising advanced external robotics, additional habitation, refueling capability, and possibly other enhancements. Canada announced in February 2019 its intention to participate in the Gateway and contribute advanced external robotics. In December 2020, the Canadian Space Agency awarded a contract to MDA to build the Canadarm3 for Artemis deep space missions. In October 2019, Japan announced plans to join the United States on the Gateway with contributions of habitation components and logistics resupply. In November 2019, the European Space Agency (ESA) received authorization and funding to support its contributions to the Gateway including habitation and refueling. In October 2020, ESA signed an agreement with NASA to contribute habitation and refueling modules and enhanced lunar communications to the Gateway. ESA also provides two additional European Service Modules for NASA’s Orion spacecraft. In November 2020, Canada signed a Gateway agreement to contribute external robotics and in December 2020, Japan signed an agreement to partner with NASA on the Gateway as well.
