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.

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.

Artistic rendering of Intuitive Machines’ Nova-C lander on the surface of the Moon.Credit: Intuitive Machines NASA’s Polar Resources Ice Mining Experiment-1 (PRIME-1) is preparing to explore the Moon’s subsurface and analyze where lunar resources may reside. The experiment’s two key instruments will demonstrate our ability to extract and analyze lunar soil to better understand the lunar environment and subsurface resources, paving the way for sustainable human exploration under the agency’s Artemis campaign for the benefit of all.
Its two instruments will work in tandem: The Regolith and Ice Drill for Exploring New Terrains (TRIDENT) will drill into the Moon’s surface to collect samples, while the Mass Spectrometer Observing Lunar Operations (MSOLO) will analyze these samples to determine the gas composition released across the sampling depth. The PRIME-1 technology will provide valuable data to help us better understand the Moon’s surface and how to work with and on it.
“The ability to drill and analyze samples at the same time allows us to gather insights that will shape the future of lunar resource utilization,” said Jackie Quinn, PRIME-1 project manager at NASA’s Kennedy Space Center in Florida. “Human exploration of the Moon and deep space will depend on making good use of local resources to produce life-sustaining supplies necessary to live and work on another planetary body.”
The PRIME-1 experiment is one of the NASA payloads aboard the next lunar delivery through NASA’s CLPS (Commercial Lunar Payload Services) initiative, set to launch from the agency’s Kennedy Space Center no earlier than Wednesday, Feb. 26, on Intuitive Machines’ Athena lunar lander and explore the lunar soil in Mons Mouton, a lunar plateau near the Moon’s South Pole.
Developed by Honeybee Robotics, a Blue Origin Company, TRIDENT is a rotary percussive drill designed to excavate lunar regolith and subsurface material up to 3.3 feet (1 meter) deep. The drill will extract samples, each about 4 inches (10 cm) in length, allowing scientists to analyze how trapped and frozen gases are distributed at different depths below the surface.
The TRIDENT drill is equipped with carbide cutting teeth to penetrate even the toughest lunar materials. Unlike previous lunar drills used by astronauts during the Apollo missions, TRIDENT will be controlled from Earth. The drill may provide key information about subsurface soil temperatures as well as gain key insight into the mechanical properties of the lunar South Pole soil. Learning more about regolith temperatures and properties will greatly improve our understanding of the environments where lunar resources may be stable, revealing what resources may be available for future Moon missions.
A commercial off-the-shelf mass spectrometer, MSOLO, developed by INFICON and made suitable for spaceflight at Kennedy, will analyze any gas released from the TRIDENT drilled samples, looking for the potential presence of water ice and other gases trapped beneath the surface. These measurements will help scientists understand the Moon’s potential for resource utilization.
Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA is one of many customers on future flights. PRIME-1 was funded by NASA’s Space Technology Mission Directorate Game Changing Development program.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A team at JPL packed up three small Moon rovers, delivering them in February to the facility where they’ll be attached to a commercial lunar lander in preparation for launch. The rovers are part of a project called CADRE that could pave the way for potential future multirobot missions.. NASA/JPL-Caltech A trio of suitcase-size rovers and their base station have been carefully wrapped up and shipped off to join the lander that will deliver them to the Moon’s surface.
Three small NASA rovers that will explore the lunar surface as a team have been packed up and shipped from the agency’s Jet Propulsion Laboratory in Southern California, marking completion of the first leg of the robots’ journey to the Moon.
The rovers are part of a technology demonstration called CADRE (Cooperative Autonomous Distributed Robotic Exploration), which aims to show that a group of robots can collaborate to gather data without receiving direct commands from mission controllers on Earth. They’ll use their cameras and ground-penetrating radars to send back imagery of the lunar surface and subsurface while testing out the novel software that enables them to work together autonomously.
The CADRE rovers will launch to the Moon aboard IM-3, Intuitive Machines’ third lunar delivery, which has a mission window that extends into early 2026, as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative. Once installed on Intuitive Machines’ Nova-C lander, they’ll head to the Reiner Gamma region on the western edge of the Moon’s near side, where the solar-powered, suitcase-size rovers will spend the daylight hours of a lunar day (the equivalent of about 14 days on Earth) carrying out experiments. The success of CADRE could pave the way for potential future missions with teams of autonomous robots supporting astronauts and spreading out to take simultaneous, distributed scientific measurements.
Members of a JPL team working on NASA’s CADRE technology demonstration use temporary red handles to move one of the project’s small Moon rovers to prepare it for transport to Intuitive Machines’ Houston facility, where it will be attached to the company’s third lunar lander. Construction of the CADRE hardware — along with a battery of rigorous tests to prove readiness for the journey through space — was completed in February 2024.
To get prepared for shipment to Intuitive Machines’ Houston facility, each rover was attached to its deployer system, which will lower it via tether from the lander onto the dusty lunar surface. Engineers flipped each rover-deployer pair over and attached it to an aluminum plate for safe transit. The rovers were then sealed in protective metal-frame enclosures that were fitted snuggly into metal shipping containers and loaded onto a truck. The hardware arrived safely on Sunday, Feb. 9.
“Our small team worked incredibly hard constructing these robots and putting them to the test, and we have been eagerly waiting for the moment where we finally see them on their way,” said Coleman Richdale, the team’s assembly, test, and launch operations lead at JPL. “We are all genuinely thrilled to be taking this next step in our journey to the Moon, and we can’t wait to see the lunar surface through CADRE’s eyes.”
The rovers, the base station, and a camera system that will monitor CADRE experiments on the Moon will be integrated with the lander — as will several other NASA payloads — in preparation for the launch of the IM-3 mission.
More About CADRE
A division of Caltech in Pasadena, California, JPL manages CADRE for the Game Changing Development program within NASA’s Space Technology Mission Directorate. The technology demonstration was selected under the agency’s Lunar Surface Innovation Initiative, which was established to expedite the development of technologies for sustained presence on the lunar surface. NASA’s Science Mission Directorate manages the CLPS initiative. The agency’s Glenn Research Center in Cleveland and its Ames Research Center in Silicon Valley, California, both supported the project. Motiv Space Systems designed and built key hardware elements at the company’s Pasadena facility. Clemson University in South Carolina contributed research in support of the project.
