Gateway’s HALO (Habitation and Logistics Outpost) in a cleanroom at Thales Alenia Space in Turin, Italy. After final installations are complete, it will be packaged and transported to the United States for final outfitting before being integrated with Gateway’s Power and Propulsion Element and launched to lunar orbit. Thales Alenia Space Through the Artemis campaign, NASA will send astronauts on missions to and around the Moon. The agency and its international partners report progress continues on Gateway, the first space station that will permanently orbit the Moon, after visiting the Thales Alenia Space facility in Turin, Italy, where initial fabrication for one of two Gateway habitation modules is nearing completion.
Leaders from NASA, ESA (European Space Agency), and the Italian Space Agency, as well as industry representatives from Northrop Grumman and Thales Alenia Space, were in Turin to assess Gateway’s HALO (Habitation and Logistics Outpost) module before its primary structure is shipped from Italy to Northrop Grumman’s Gilbert, Arizona site in March. Following final outfitting and verification testing, the module will be 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,” said Jon Olansen, manager, Gateway Program, at NASA’s Johnson Space Center in Houston. “We’re excited to celebrate this major flight hardware milestone, and this is just the beginning – there’s impressive and important progress taking shape with our partners around the globe, united by our shared desire to expand human exploration of our solar system while advancing scientific discovery.”

These integrated modules will launch aboard a SpaceX Falcon Heavy rocket and spend about a year traveling uncrewed to lunar orbit, while providing scientific data on solar and deep space radiation during transit.
Launching atop HALO will be ESA’s Lunar Link communication system, which will provide high-speed communication between the Moon and Gateway. The system is undergoing testing at another Thales Alenia Space facility in Cannes, France.
Once in lunar orbit, Gateway will continue scientific observations while awaiting the arrival of Artemis IV astronauts aboard an Orion spacecraft which will deliver and dock Gateway’s second pressurized habitable module, the ESA-led Lunar I-Hab. Thales Alenia Space, ESA’s primary contractor for the Lunar I-Hab and Lunar View refueling module, has begun production of the Lunar I-Hab, and design of Lunar View in Turin.

Maxar Space Systems is assembling the Power and Propulsion Element, which will make Gateway the most powerful solar electric propulsion spacecraft ever flown. Major progress in 2024 included installation of Xenon and chemical propulsion fuel tanks, and qualification of the largest roll-out solar arrays ever built. NASA and its partners will complete propulsion element assembly, and acceptance and verification testing of next-generation electric propulsion thrusters this year.
The main bus of Gateway’s Power and Propulsion Element undergoes assembly and installations at Maxar Space Systems in Palo Alto, California.Maxar Space Systems SpaceX will provide both the Starship human landing system that will land astronauts on the lunar surface during NASA’s Artemis III mission and ferry astronauts from Gateway to the lunar South Pole region during Artemis IV, as well as provide logistics spacecraft to support crewed missions.
NASA also has selected Blue Origin to develop Blue Moon, the 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 in preparation for future missions to Mars.
CSA (Canadian Space Agency) is developing Canadarm3, an advanced robotics system, and JAXA (Japan Aerospace Exploration Agency) is designing and testing Lunar I-Hab’s vital life support systems, batteries, and a resupply and logistics vehicle called HTV-XG.
NASA’s newest Gateway partner, the Mohammad Bin Rashid Space Centre (MBRSC) of the United Arab Emirates, kicked off early design for the Gateway Crew and Science Airlock that will be delivered on Artemis VI. The selection of Thales Alenia Space as its airlock prime contractor was announced by MBRSC on Feb. 4.
Development continues to advance on three radiation-focused initial science investigations aboard Gateway. These payloads will help scientists better understand unpredictable space weather from the Sun and galactic cosmic rays that will affect astronauts and equipment during Artemis missions to the Moon and beyond.
The Gateway lunar space station is a multi-purpose platform that offers capabilities for long-term exploration in deep space in support of NASA’s Artemis campaign and Moon to Mars objectives. Gateway will feature docking ports for a variety of visiting spacecraft, as well as space for crew to live, work, and prepare for lunar surface missions. As a testbed for future journeys to Mars, continuous investigations aboard Gateway will occur with and without crew to better understand the long-term effects of deep space radiation on vehicle systems and the human body as well as test and operate next generation spacecraft systems that will be necessary to send humans to Mars.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
How to Attend
The workshop will be hosted by NASA Jet Propulsion Laboratory.
Virtual and in-person attendance are available. Registration is required for both. (Link coming soon!)
Virtual attendees will receive connection information one week before the workshop.
Background, Goals and Objectives
The NASA Engineering and Safety Center (NESC) is conducting an assessment of the state of cold capable electronics for future lunar surface missions. The intent is to enable the continuous use of electronics with minimal or no thermal management on missions of up to 20 years in all regions of the lunar surface, e.g., permanently shadowed regions and equatorial. The scope of the assessment includes: capture of the state of cold electronics at NASA, academia, and industry; applications and challenges for lunar environments; gap analyses of desired capabilities vs state of the art/practice; guidance for cold electronics selection, evaluation and qualification; and recommendations for technology advances and follow-on actions to close the gaps. The preliminary report of the assessment will be available the first week of April 2025 on this website, i.e., 3 weeks prior to the workshop. Attendees are urged to read the report beforehand as the workshop will provide only a limited, high-level summary of the report’s key findings. The goal of the workshop is to capture your feedback with regards to the findings of the report, especially in the areas below: Technologies, new or important studies or data that we missed. Gaps, i.e. requirements vs available capabilities that we missed. Additional recommendations, suggestions, requests, that we missed.

Eclipses to Auroras: Eclipse Ambassadors Experience Winter Field School in Alaska
In 2023 and 2024, two eclipses crossed the United States, and the NASA Science Activation program’s Eclipse Ambassadors Off the Path project invited undergraduate students and amateur astronomers to join them as “NASA Partner Eclipse Ambassadors”. This opportunity to partner with NASA, provide solar viewing glasses, and share eclipse knowledge with underserved communities off the central paths involved:
Partnering with an undergraduate/amateur astronomer Taking a 3-week cooperative course (~12 hours coursework) Engaging their communities with eclipse resources by reaching 200+ people These Eclipse Ambassador partnerships allowed participants to grow together as they learned new tools and techniques for explaining eclipses and engaging with the public, and Eclipse Ambassadors are recognized for their commitment to public engagement.
In January 2025, the Eclipse Ambassadors Off the Path project held a week-long Heliophysics Winter Field School (WFS), a culminating Heliophysics Big Year experience for nine undergraduate and graduate Eclipse Ambassadors. The WFS exposed participants to career opportunities and field experience in heliophysics, citizen science, and space physics. The program included expert lectures on space physics, aurora, citizen science, and instrumentation, as well as hands-on learning opportunities with Poker Flat Rocket Range, the Museum of the North, aurora chases, and more. Students not only learned about heliophysics, they also actively participated in citizen science data collection using a variety of instruments, as well as the Aurorasaurus citizen science project app. Interactive panels on career paths helped prepare them to pursue relevant careers.
One participant, Sophia, said, “This experience has only deepened my passion for heliophysics, science communication, and community engagement.” Another participant, Feras, reflected, “Nine brilliant students from across the country joined a week-long program at the University of Alaska Fairbanks’ (UAF) Geophysical Institute, where we attended multiple panels on solar and space physics, spoke to Athabaskan elders on their connection to the auroras, and visited the Poker Flat Research Range to observe the stunning northern lights.”
This undertaking would not have been possible without the coordination, planning, leadership of many. Principal Investigators included Vivian White (Eclipse Ambassadors, Astronomical Society of the Pacific, ASP) and Dr. Elizabeth McDonald (Aurorasaurus, NASA GSFC). Other partners included Lynda McGilvary (Geophysical Institute at UAF), Jen Arseneau (UAF), Shanil Virani (ASP), Andréa Hughes (NASA), and Lindsay Glesener (University of Minnesota), as well as knowledge holders, students, and scientists.
The Eclipse Ambassadors Off the Path project is supported by NASA under cooperative agreement award number 80NSS22M0007 and is part of NASA’s Science Activation Portfolio. To learn more, visit: www.eclipseambassadors.org.
