Preparations for Next Moonwalk Simulations Underway (and Underwater)
Gateway’s HALO module at Northrop Grumman’s facility in Gilbert, Arizona, on April 4, 2025, shortly after its arrival from Thales Alenia Space in Turin, Italy. NASA/Josh Valcarcel NASA continues to mark progress on plans to work with commercial and international partners as part of the Gateway program. The primary structure of HALO (Habitation and Logistics Outpost) arrived at Northrop Grumman’s facility in Gilbert, Arizona, where it will undergo final outfitting and verification testing.
HALO will provide Artemis astronauts with space to live, work, and conduct scientific research. The habitation module will be equipped with essential systems including command and control, data handling, energy storage, power distribution, and thermal regulation.
Following HALO’s arrival on April 1 from Thales Alenia Space in Turin, Italy, where it was assembled, NASA and Northrop Grumman hosted an April 24 event to acknowledge the milestone, and the module’s significance to lunar exploration. The event opened with remarks by representatives from Northrop Grumman and NASA, including NASA’s Acting Associate Administrator for Exploration Systems Development Lori Glaze, Gateway Program Manager Jon Olansen, and NASA astronaut Randy Bresnik. Event attendees, including Senior Advisor to the NASA Administrator Todd Ericson, elected officials, and local industry and academic leaders, viewed HALO and virtual reality demonstrations during a tour of the facilities.
Dr. Lori Glaze, acting associate administrator for NASA’s Exploration Systems Development Mission Directorate, and Dr. Jon B. Olansen, Gateway Program manager, on stage during an April 24, 2025, event at Northrop Grumman’s facility in Gilbert, Arizona, commemorating HALO’s arrival in the United States. Northrop Grumman While the module is in Arizona, HALO engineers and technicians will install propellant lines for fluid transfer and electrical lines for power and data transfer. Radiators will be attached for the thermal control system, as well as racks to house life support hardware, power equipment, flight computers, and avionics systems. Several mechanisms will be mounted to enable docking of the Orion spacecraft, lunar landers, and visiting spacecraft.
Launching on top of HALO is the ESA (European Space Agency)-provided Lunar Link system which will enable communication between crewed and robotic systems on the Moon and to mission control on Earth. Once these systems are installed, the components will be tested as an integrated spacecraft and subjected to thermal vacuum, acoustics, vibration, and shock testing to ensure the spacecraft is ready to perform in the harsh conditions of deep space.
In tandem with HALO’s outfitting at Northrop Grumman, the Power and Propulsion Element – a powerful solar electric propulsion system – is being assembled at Maxar Space Systems in Palo Alto, California. Solar electric propulsion uses energy collected from solar panels converted to electricity to create xenon ions, then accelerates them to more than 50,000 miles per hour to create thrust that propels the spacecraft.
The element’s central cylinder, which resembles a large barrel, is being attached to the propulsion tanks, and avionics shelves are being installed. The first of three 12-kilowatt thrusters has been delivered to NASA’s Glenn Research Center in Cleveland for acceptance testing before delivery to Maxar and integration with the Power and Propulsion Element later this year.

Searching for the Dark in the Light
The Perseverance rover acquired this image of the “Hare Bay” abrasion patch using its SHERLOC WATSON camera (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals, and the Wide Angle Topographic Sensor for Operations and eNgineering), located on the turret at the end of the rover’s robotic arm. This image was acquired on April 18, 2025 (Sol 1479, or Martian day 1,479 of the Mars 2020 mission) at the local mean solar time of 12:53:57. NASA/JPL-Caltech Written by Eleanor Moreland, Ph.D. Student Collaborator at Rice University
Perseverance has been busy exploring lower “Witch Hazel Hill,” an outcrop exposed on the edge of the Jezero crater rim. The outcrop is composed of alternating light and dark layers, and naturally, the team has been trying to understand the makeup of and relationships between the light and dark layers. A few weeks ago, we sampled one of the light-toned layers, which we discovered was made up of very small clasts, or fragments of rocks or minerals, at “Main River.” Since then, we have learned that the dark layers tend to be composed of larger clasts compared to the light layers, and we’ve been searching for a place to sample this coarser-grained rock type. Sometimes, these coarser-grained rocks also contain spherules, which are of great interest to the science team because they provide clues about the process that formed these layered rocks.
Perseverance first looked at a dark layer at “Puncheon Rock” with an abrasion. We then examined a dark layer at “Wreck Apple,” near “Sally’s Cove,” but we could not identify a suitable surface to abrade. So, while team members searched for other locations to study the coarse-grained units and spherules, Perseverance drove south to “Port Anson.”
Perseverance acquired this image of the “Strong Island” workspace near Port Anson using its onboard Front Left Hazard Avoidance Camera A (https://science.nasa.gov/mission/mars-2020-perseverance/rover-components/#eyes). This image was acquired on April 12, 2025 (Sol 1473, or Martian day 1,473 of the Mars 2020 mission) at the local mean solar time of 12:50:32. NASA/JPL-Caltech Port Anson was intriguing because, from orbit, it showed a clear contact between the light layers of Witch Hazel Hill and a distinct unit below it. And, although the rocks below the Port Anson contact do show interesting compositional differences with those of Witch Hazel Hill, they weren’t the coarse-grained rocks we were looking for. We still performed an abrasion there, at Strong Island, before driving back up north for another attempt at investigating the coarser-grained rocks.
We aimed for “Pine Pond,” which neighbors “Dennis Pond,” to abrade at “Hare Bay.” With the data just coming down over the weekend, the team will be hard at work to figure out if we captured the coarse grains and spherules, and if it is representative of rocks we have seen before or not. The image below is a close-up of this most recent abrasion patch at Hare Bay — what do you think? Stay tuned to find out!

The New York Stock Exchange welcomed team members from NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) mission to celebrate the launch of the agency’s newest astrophysics observatory to understand the origins and structure of the universe. Image courtesy of NYSE Group Members of NASA’s recently launched SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) mission team participated in the New York Stock Exchange’s closing bell ceremony in New York City on April 22.
Michael Thelen, SPHEREx flight system manager at NASA’s Jet Propulsion Laboratory in Southern California, is seen here ringing the closing bell. Additional SPHEREx team members from NASA JPL, which manages the mission, and BAE Systems Inc., Space & Mission Systems, which built the telescope and spacecraft bus for NASA, participated.
The SPHEREx observatory, which launched March 11 from Vandenberg Space Force Base in California on a SpaceX Falcon 9 rocket, will soon begin mapping the universe like none before it. Using 102 color filters to scan the entire sky quickly, SPHEREx will gather data on hundreds of millions of galaxies that will complement the work of more targeted telescopes, like NASA’s Hubble and James Webb space telescopes. Its surveys will help answer some of the biggest questions in astrophysics: what happened in the first second after the big bang, how galaxies form and evolve, and the origins and abundance of water and other key ingredients for life in our galaxy.

SPHEREx is managed by JPL for NASA’s Astrophysics Division within the Science Mission Directorate in Washington. BAE Systems (formerly Ball Aerospace) built the telescope and the spacecraft bus. The science analysis of the SPHEREx data will be conducted by a team of scientists located at 10 institutions across the U.S. and in South Korea. Data will be processed and archived at IPAC at Caltech, which manages JPL for NASA. The mission principal investigator is based at Caltech with a joint JPL appointment. The SPHEREx dataset will be publicly available.
