NASA’s Progress on Gateway: A Crucial Step in the Moon to Mars Initiative
NASA, in collaboration with international partners, is making significant strides in the development of Gateway, a lunar space station set to orbit the Moon. This venture is a central component of NASA’s ambitious Moon to Mars strategy, part of the broader Artemis campaign which aims to send astronauts on missions to and around the Moon.
Through the Artemis campaign, NASA plans to conduct manned missions to the Moon, with the Gateway space station playing a pivotal role. The agency, alongside its international collaborators, has reported substantial progress in the construction of Gateway, which will be the first space station to permanently orbit the Moon. Recent developments were highlighted during a visit to the Thales Alenia Space facility in Turin, Italy, where the initial fabrication of one of the two habitation modules for Gateway is nearing completion.
International Collaboration for Gateway’s Development
Key figures from NASA, the European Space Agency (ESA), the Italian Space Agency, and industry representatives from Northrop Grumman and Thales Alenia Space convened in Turin to evaluate the progress of Gateway’s HALO (Habitation and Logistics Outpost) module. This module is a crucial component of the Gateway and is set to be shipped to Northrop Grumman’s facility in Gilbert, Arizona, in March. Once there, it will undergo final outfitting and verification testing before being integrated with the Power and Propulsion Element at NASA’s Kennedy Space Center in Florida.
"Building and testing hardware for Gateway is truly an international collaboration," stated Jon Olansen, manager of the Gateway Program at NASA’s Johnson Space Center in Houston. He expressed excitement over reaching this significant milestone, emphasizing that it marks the beginning of a series of impressive and essential advancements with partners worldwide, all united by the goal of expanding human exploration of our solar system and advancing scientific discovery.
Preparing for Artemis IV
In preparation for Artemis IV, the first crewed mission to Gateway, NASA is targeting the launch of the HALO module and the Power and Propulsion Element no later than December 2027. These integrated modules will launch aboard a SpaceX Falcon Heavy rocket and will embark on a year-long uncrewed journey to lunar orbit. During this transit, they will provide scientific data on solar and deep space radiation.
ESA’s Lunar Link communication system, designed to facilitate high-speed communication between the Moon and Gateway, will launch atop HALO. This system is currently undergoing testing at another Thales Alenia Space facility in Cannes, France.
Once Gateway reaches lunar orbit, it will continue scientific observations while awaiting the arrival of astronauts from the Artemis IV mission. These astronauts will travel aboard an Orion spacecraft, which will deliver and dock Gateway’s second pressurized habitable module, known as the ESA-led Lunar I-Hab. Thales Alenia Space, ESA’s primary contractor for the Lunar I-Hab and Lunar View refueling module, has commenced production of the Lunar I-Hab and is designing the Lunar View in Turin.
Progress in HALO Module and Power and Propulsion Element
Northrop Grumman and its subcontractor, Thales Alenia Space, successfully completed the welding of the HALO module in 2024, and it has since passed pressure and stress tests. These tests are crucial to ensure the module’s suitability for the harsh environment of deep space.
Maxar Space Systems is responsible for assembling the Power and Propulsion Element, which will make Gateway the most powerful solar electric propulsion spacecraft ever flown. Major progress in 2024 included the installation of Xenon and chemical propulsion fuel tanks and the qualification of the largest roll-out solar arrays ever built. NASA and its partners will complete the propulsion element assembly and conduct acceptance and verification testing of next-generation electric propulsion thrusters this year.
SpaceX and Blue Origin’s Role in Lunar Missions
SpaceX is tasked with providing the Starship human landing system, which will land astronauts on the lunar surface during NASA’s Artemis III mission. This system will also transport astronauts from Gateway to the lunar South Pole region during Artemis IV and provide logistics spacecraft to support crewed missions.
Additionally, NASA has selected Blue Origin to develop the Blue Moon human landing system for Artemis V, as well as logistics spacecraft for future Artemis missions. Having two distinct lunar landing designs provides flexibility and supports a regular cadence of Moon landings as NASA prepares for future missions to Mars.
Contributions from CSA, JAXA, and MBRSC
The Canadian Space Agency (CSA) is developing Canadarm3, an advanced robotics system, while the Japan Aerospace Exploration Agency (JAXA) is designing and testing the Lunar I-Hab’s vital life support systems, batteries, and a resupply and logistics vehicle called HTV-XG.
NASA’s newest Gateway partner, the Mohammed Bin Rashid Space Centre (MBRSC) of the United Arab Emirates, has initiated the early design phase for the Gateway Crew and Science Airlock, which will be delivered on Artemis VI. Thales Alenia Space has been selected as the prime contractor for this airlock.
Advancing Scientific Investigations Aboard Gateway
Development is underway for three initial science investigations focused on radiation aboard Gateway. These payloads aim to enhance our understanding of unpredictable space weather from the Sun and galactic cosmic rays, which could affect astronauts and equipment during Artemis missions to the Moon and beyond.
Gateway: A Multi-Purpose Platform for Exploration
The Gateway lunar space station is designed as a multi-purpose platform, offering capabilities for long-term exploration in deep space. It supports NASA’s Artemis campaign and Moon to Mars objectives. Gateway will feature docking ports for various visiting spacecraft and provide space for crew to live, work, and prepare for lunar surface missions.
Serving as a testbed for future journeys to Mars, Gateway will facilitate continuous investigations with and without crew to better understand the long-term effects of deep space radiation on vehicle systems and the human body. It will also serve as a platform to test and operate next-generation spacecraft systems, which are essential for sending humans to Mars.
