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.

Hubble Spies a Spiral That May Be Hiding an Imposter

The sparkling spiral galaxy gracing this NASA/ESA Hubble Space Telescope image is UGC 5460, which sits about 60 million light-years away in the constellation Ursa Major. This image combines four different wavelengths of light to reveal UGC 5460’s central bar of stars, winding spiral arms, and bright blue star clusters. Also captured in the upper left-hand corner is a far closer object: a star just 577 light-years away in our own galaxy.
UGC 5460 has hosted two recent supernovae: SN 2011ht and SN 2015as. It’s because of these two stellar explosions that Hubble targeted this galaxy, collecting data for three observing programs that aim to study various kinds of supernovae.
SN 2015as was as a core-collapse supernova: a cataclysmic explosion that happens when the core of a star far more massive than the Sun runs out of fuel and collapses under its own gravity, initiating a rebound of material outside the core. Hubble observations of SN 2015as will help researchers understand what happens when the expanding shockwave of a supernova collides with the gas that surrounds the exploded star.
SN 2011ht might have been a core-collapse supernova as well, but it could also be an impostor called a luminous blue variable. Luminous blue variables are rare stars that experience eruptions so large that they can mimic supernovae. Crucially, luminous blue variables emerge from these eruptions unscathed, while stars that go supernova do not. Hubble will search for a stellar survivor at SN 2011ht’s location with the goal of revealing the explosion’s origin.

Modeling properties of thunderstorm discharges
Researchers report detailed physical properties of different types of corona discharges, including single- and multi-pulse blue discharges linked to powerful but short-lived electrical bursts near the tops of clouds. These details provide a reference for further investigation into the physical mechanisms behind these discharges and their role in the initiation of lightning, an important problem in lightning physics.
An ESA (European Space Agency) instrument used to study thunderstorms, Atmosphere-Space Interactions Monitor (ASIM) provides insights into their role in Earth’s atmosphere and climate, including mechanisms behind the creation of lightning. Understanding how thunderstorms and lightning disturb the upper atmosphere could improve atmospheric models along with climate and weather predictions. These high-altitude discharges also affect aircraft and spacecraft safety.

Researchers conclude that the space station’s ECOSTRESS instrument yields highly accurate sea surface temperature data. Given the instrument’s global coverage and high spatial resolution, these data have potential use in studies of biological and physical oceanography to evaluate regional and local effects of climate change.
ECOSTRESS resolves oceanographic features not detectable in imagery from NOAA’s Visible Infrared Imaging Radiometer Suite satellite, and has open-ocean coverage, unlike Landsat. Satellites are a fundamental tool to measure sea surface temperatures, which are rising across all oceans due to atmospheric warming induced by climate change.

Researchers report detailed observations and analysis of emissions from an exceptionally bright gamma ray burst (GRB), 210619B, detected by the station’s ASIM and other satellite and ground-based instruments. These observations could be useful in determining various properties of GRBs and how they change during different phases.
Believed to be generated by the collapse of massive stars, GRBs are the brightest, most explosive transient electromagnetic events in the universe. ASIM can observe thunderstorm discharges difficult to observe from the ground. It has a mode where a detected event triggers observation and onboard storage of data.
