Through NASA’s Artemis campaign, astronauts will land on the lunar surface and use a new generation of spacesuits and rovers as they live, work, and conduct science in the Moon’s South Pole region, exploring more of the lunar surface than ever before. Recently, the agency completed the first round of testing on three commercially owned and developed lunar terrain vehicles (LTVs) from Intuitive Machines, Lunar Outpost, and Venturi Astrolab at NASA’s Johnson Space Center in Houston.

As part of an ongoing year-long feasibility study, each company delivered a static mockup of their vehicle to Johnson at the end of September, initiated rover testing in October and completed the first round of testing in December inside the Active Response Gravity Offload System (ARGOS) test facility. Lunar surface gravity is one-sixth of what we experience here on Earth, so to mimic this, ARGOS offers an analog environment that can offload pressurized suited subjects for reduced gravity simulations.

NASA’s engineering teams conducted tests where suited NASA astronauts and engineers performed tasks, maneuvers, and emergency drills on each rover. With astronauts acting as the test subjects, these human-in-the-loop tests are invaluable as crewmembers provide critical feedback on each rover’s design functionality, evaluate display interfaces and controls, and help identify potential safety concerns or design issues. This feedback is shared directly with each commercial provider, to incorporate changes based on lessons learned as they evolve their rover design.

“We are excited to have mockups from all three LTV commercial providers here at Johnson Space Center,” said Steve Munday, LTV project manager. “This is the first major test milestone within the Lunar Terrain Vehicle Services contract and to have actual rovers delivered only four months after these companies were awarded is remarkable."

Testing consisted of NASA astronauts and engineers taking turns wearing both NASA’s Exploration Extravehicular Mobility Unit planetary prototype spacesuit as well as Axiom Space’s Axiom Extravehicular Mobility Unit lunar spacesuit. The test teams performed evaluations to understand the interactions between the crew, the spacesuits, and the LTV mockups. 

While wearing NASA’s prototype spacesuit, crew members were suspended from ARGOS allowing teams to mimic theone-sixth gravitational field of the lunar surface. This allowed the crew members to conduct tasks on the outside of each rover, such as gathering or storing lunar geology tools, deploying science payloads, and handling cargo equipment, as if they are walking on the Moon.

While wearing Axiom Space’s pressurized spacesuit, teams evaluated the level of ease or difficulty in mobility crewmembers experienced when entering and exiting the rovers, the crew compartment and design, and the functionality of interacting with display interfaces and hand controls while wearing thick spacesuit gloves.

As part of testing, teams also conducted emergency drills, where engineers simulated rescuing an incapacitated crew member. As part of NASA’s requirements, each rover must have a design in place that enables an astronaut to single-handedly rescue their crewmates in the event of an emergency.

Since NASA selected the companies, Intuitive Machines, Lunar Outpost, and Venturi Astrolab have been working to meet NASA’s requirements through the preliminary design review. In 2025, the agency plans to issue a request for task order proposals to any eligible providers for a demonstration mission to continue developing the LTV, deliver it to the surface of the Moon, and validate its performance and safety ahead of Artemis V, when NASA intends to begin using the LTV for crewed operations.

Through Artemis, NASA will send astronauts—including the next Americans, and the first international partner astronaut—to explore the Moon for scientific discovery, technology evolution, economic benefits, and to build the foundation for future crewed missions to Mars.

Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner of Russia concluded their spacewalk (RU EVA-63) on December 19, 2024, at 5:53 p.m. EST after seven hours and 17 minutes. Ovchinin and Vagner completed all of their major objectives. This included installing an experiment package designed to monitor celestial x-ray sources and new electrical connector patch panels and removing several experiments for disposal. The two cosmonauts were unable to complete their non-critical final extravehicular (EVA) objective due to time constraints. This was to relocate a control panel for the European robotic arm, attached to the Nauka multipurpose laboratory module.

This was the second spacewalk in Ovinchin’s career, and the first for Vagner. It is the 272nd spacewalk for space station assembly, maintenance, and upgrades.

"We Are Team Blue": Looking Ahead to 2025 | Blue Origin

"We Are Team Blue": Looking Ahead to 2025 | Blue Origin

At Blue Origin, "our genuine passion for space exploration is reflected in our work. We are looking for individuals who share this passion and wish to turn their careers into a calling. Together, we are shaping the future of space, and we seek dedicated and inspired people to join us."

Blue Origin's advanced heavy-lift vehicle, the New Glenn Rocket, will support NASA Artemis Moon Missions. 

New Glenn is named after former NASA astronaut John Glenn, the first American to orbit Earth. The rocket stands more than 320 feet (98 meters) high—roughly the height of a 30-story building—and features a seven-meter payload fairing, enabling twice the volume of standard five-meter class commercial launch systems. The fairing is large enough to hold three school buses. Its reusable first stage aims for a minimum of 25 missions and will land on a sea-based platform located roughly 620 miles (1,000 km) downrange. Reusability is integral to radically reducing cost-per-launch. 

The vehicle is powered by seven of Blue Origin’s BE-4 engines, the most powerful liquid oxygen (LOX)/liquefied natural gas (LNG) engine developed since Saturn V’s F1 engines. LNG is cleaner-burning and higher-performing than kerosene-based fuels. 

Blue Origin has several New Glenn vehicles in production and a full customer manifest. Customers include NASA, Project Kuiper, Telesat, and Eutelsat, among others.

NASA's SunRISE Mission: Monitoring Solar Radiation Storms from Space | JPL

NASA's SunRISE Mission: Monitoring Solar Radiation Storms from Space | JPL

NASA’s SunRISE Mission is getting ready to reveal the turbulent workings of our star. Short for Sun Radio Interferometer Space Experiment, SunRISE is an array of six toaster-size spacecraft that will work together to track solar activity and help scientists better understand space weather events. 

Our active, churning Sun often sends unpredictable bursts of energy across the solar system in the form of solar flares and coronal mass ejections that can generate beautiful auroras at Earth. While traveling through the Sun’s atmosphere, these energetic events can trigger secondary bursts of solar energetic particles, causing solar radiation storms. At Earth, these storms can damage orbiting spacecraft or unprotected astronauts. SunRISE will  map the radio wave emissions that accompany such events for the first time. 

In this mission overview, scientists and engineers explain how the mission will help them better understand—and perhaps one day, predict—solar eruptions.

Spiral Galaxy NGC 337 in Cetus: A Supernova Checkup | Hubble

Spiral Galaxy NGC 337 in Cetus: A Supernova Checkup | Hubble


The subject of this NASA/European Space Agency Hubble Space Telescope picture is the spiral galaxy NGC 337, located about 60 million light-years away in the constellation Cetus (The Whale).

This image combines observations made at two wavelengths, highlighting the galaxy’s golden center and blue outskirts. The golden central glow comes from older stars, while the sparkling blue edges get their color from young stars. If Hubble had observed NGC 337 about a decade ago, the telescope would have spotted something remarkable among the hot blue stars along the galaxy’s edge: a brilliant supernova.

The supernova, named SN 2014cx, is remarkable for having been discovered nearly simultaneously in two vastly different ways: by a prolific supernova hunter, Koichi Itagaki, and by the All Sky Automated Survey for SuperNovae (ASAS-SN). ASAS-SN is a worldwide network of robotic telescopes that scans the sky for sudden events like supernovae. 

Researchers have determined that SN 2014cx was a Type IIP supernova. The “Type II” classification means that the exploding star was a supergiant at least eight times as massive as the Sun. The “P” stands for plateau, meaning that after the light from the supernova began to fade, the level reached a plateau, remaining at the same brightness for several weeks or months before fading further. This type of supernova occurs when a massive star can no longer produce enough energy in its core to stave off the crushing pressure of gravity. SN 2014cx’s progenitor star is estimated to have been ten times more massive than the Sun and hundreds of times as wide. Though it has long since dimmed from its initial brilliance, researchers are still keeping tabs on this exploded star, not least through the Hubble observing program that produced this image.

Image Description: A barred spiral galaxy on a dark background. The galaxy’s central region is a pale color due to older stars, contains pale reddish threads of dust, and is brighter along a broad horizontal bar through the very center. Off the bar come several stubby spiral arms, merging into the outer region of the disc. It is a cool blue color and contains bright sparkling blue spots, indicating young hot stars.

Lenticular Galaxy NGC 5084 (with 'sideways' black hole) | Schulman Telescope

Lenticular Galaxy NGC 5084 (with 'sideways' black hole) | Schulman Telescope

NGC 5084 is a lenticular galaxy in the constellation of Virgo. It is located at a distance of about 80 million light years from Earth. Given its apparent dimensions, this means that NGC 5084 is at least 200,000 light years across. It is one of the largest and most massive galaxies in the Virgo Supercluster.

NASA researchers have discovered a perplexing case of a black hole that appears to be “tipped over,” rotating in an unexpected direction relative to the galaxy surrounding it. The galaxy NGC 5084 has been known for years, but the sideways secret of its central black hole lay hidden in old data archives. The discovery was made possible by new image analysis techniques developed at NASA’s Ames Research Center in California’s Silicon Valley to take a fresh look at archival data from the agency’s Chandra X-ray Observatory.

Using the new methods, astronomers at Ames unexpectedly found four long plumes of plasma—hot, charged gas—emanating from NGC 5084. One pair of plumes extends above and below the plane of the galaxy. A surprising second pair, forming an “X” shape with the first, lies in the galaxy plane itself. Hot gas plumes are not often spotted in galaxies, and typically only one or two are present.

‘Sideways’ Black Hole Detected via New Techniques/Legacy Data | NASA Chandra

‘Sideways’ Black Hole Detected via New Techniques/Legacy Data | NASA Chandra

Image showing the structure of galaxy NGC 5084, with data from the Chandra X-ray Observatory overlaid on a visible-light image of the galaxy. Chandra’s data, shown in purple, revealed four plumes of hot gas emanating from a supermassive black hole rotating “tipped over” at the galaxy’s core.

NASA researchers have discovered a perplexing case of a black hole that appears to be “tipped over,” rotating in an unexpected direction relative to the galaxy surrounding it. That galaxy, called NGC 5084, has been known for years, but the sideways secret of its central black hole lay hidden in old data archives. The discovery was made possible by new image analysis techniques developed at NASA’s Ames Research Center in California’s Silicon Valley to take a fresh look at archival data from the agency’s Chandra X-ray Observatory.

Using the new methods, astronomers at Ames unexpectedly found four long plumes of plasma—hot, charged gas—emanating from NGC 5084. One pair of plumes extends above and below the plane of the galaxy. A surprising second pair, forming an “X” shape with the first, lies in the galaxy plane itself. Hot gas plumes are not often spotted in galaxies, and typically only one or two are present.

NGC 5084 is a lenticular galaxy in the constellation of Virgo. It is located at a distance of about 80 million light years from Earth. Given its apparent dimensions, this means that NGC 5084 is at least 200,000 light years across. It is one of the largest and most massive galaxies in the Virgo Supercluster.

The method revealing such unexpected characteristics for galaxy NGC 5084 was developed by Ames research scientist Alejandro Serrano Borlaff and colleagues to detect low-brightness X-ray emissions in data from the world’s most powerful X-ray telescope. What they saw in the Chandra data seemed so strange that they immediately looked to confirm it, digging into the data archives of other telescopes and requesting new observations from two powerful ground-based observatories.

The surprising second set of plumes was a strong clue this galaxy housed a supermassive black hole, but there could have been other explanations. Archived data from NASA’s Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile then revealed another quirk of NGC 5084: a small, dusty, inner disk turning about the center of the galaxy. This, too, suggested the presence of a black hole there, and, surprisingly, it rotates at a 90-degree angle to the rotation of the galaxy overall; the disk and black hole are, in a sense, lying on their sides.

The follow-up analyses of NGC 5084 allowed the researchers to examine the same galaxy using a broad swath of the electromagnetic spectrum—from visible light, seen by Hubble, to longer wavelengths observed by ALMA and the Expanded Very Large Array of the National Radio Astronomy Observatory near Socorro, New Mexico.

“It was like seeing a crime scene with multiple types of light,” said Borlaff, who is also the first author on the paper reporting the discovery. “Putting all the pictures together revealed that NGC 5084 has changed a lot in its recent past.”

“Detecting two pairs of X-ray plumes in one galaxy is exceptional,” added Pamela Marcum, an astrophysicist at Ames and co-author on the discovery. “The combination of their unusual, cross-shaped structure and the ‘tipped-over,’ dusty disk gives us unique insights into this galaxy’s history.”

Typically, astronomers expect the X-ray energy emitted from large galaxies to be distributed evenly in a generally sphere-like shape. When it is not, such as when concentrated into a set of X-ray plumes, they know a major event has disturbed the galaxy.

Possible dramatic moments in its history that could explain NGC 5084’s toppled black hole and double set of plumes include a collision with another galaxy and the formation of a chimney of superheated gas breaking out of the top and bottom of the galactic plane.

More studies will be needed to determine what event or events led to the current strange structure of this galaxy. However, it is already clear that the never-before-seen architecture of NGC 5084 was only discovered thanks to archival data—nearly three decades old—combined with novel analysis techniques.

The paper presenting this research was published Dec. 18, 2024, in The Astrophysical Journal:
