Preparations for Next Moonwalk Simulations Underway (and Underwater)
This illustration of Moon to Mars infrastructure shows astronauts living and working on the surface of Mars. NASA’s Moon to Mars Objectives establish an objectives-based approach to the agency’s human deep space exploration efforts; NASA’s Moon to Mars Architecture approach distills the objectives into operational capabilities and elements.
NASA is getting ready to send four astronauts around the Moon with Artemis II, laying the foundation for sustainable missions to the lunar surface and paving the way for human exploration on Mars. As the agency considers deep space endeavors that could last months or years, it must develop ways to feed astronauts beyond sending supplies from Earth.
That is why NASA is launching the Deep Space Food Challenge: Mars to Table, a new global competition inviting chefs, innovators, culinary experts, higher-education students, and citizen scientists to design a complete, Earth-independent food system for long-duration space missions.
“In the future, exploration missions will grow in both duration and distance from Earth. This will make the critical question of feeding our astronauts more complex, requiring innovative solutions to allow for long-term human exploration of space,” said Greg Stover, acting associate administrator of NASA’s Space Technology Missions Directorate at NASA Headquarters in Washington. “Opening the door to ideas from beyond the agency strengthens NASA’s ability to operate farther from Earth with greater independence.”
Mars to Table builds on NASA’s first Deep Space Food Challenge by seeking to integrate multiple food production and preparation methods into a holistic, self-sustaining system designed for use on Mars. This new challenge is open now until July 31 to the global public and carries a prize purse of up to $750,000.
“Future crews on the Moon and Mars will need food systems that are nutritious, sustainable, and fully independent from Earth,” said Jarah Meador, program executive for NASA’s Prizes, Challenges, and Crowdsourcing Program at NASA Headquarters. “Food will play a pivotal role in the overall health and happiness of future deep space explorers. The Mars to Table Challenge is about bringing all those pieces together into one comprehensive design.”
Solvers are tasked with creating a complete meal plan suitable for astronauts living on Mars, using a NASA-created mission scenario as their guide. Each team will design a full food system concept, including a detailed operations plan and system design layout that supports a surface mission. Teams must consider every detail – from nutritional balance and taste to safety, usability, and integration with NASA’s Environmental Control and Life Support Systems.
Participants in the Mars to Table Challenge are also encouraged to address food security on Earth. Innovative growth systems designed for space could make fresh food production possible in harsh, remote, or resource-limited areas, such as research stations located at Earth’s poles or in rural areas with limited access to traditional supply chains.
“This challenge isn’t just about feeding astronauts; it’s about feeding people anywhere,” said Jennifer Edmunson, acting program manager for NASA’s Centennial Challenges at NASA’s Marshall Spaceflight Center in Huntsville, Alabama. “Novel meals that are compact, shelf-stable, and nutrient-rich could expand culinary options for groups like military personnel or disaster relief responders. By solving for Mars and future planetary expeditions, we can also find solutions for Earth.”
NASA’s Centennial Challenges have a 20-year legacy of engaging the public to solve complex problems that benefit NASA’s broader initiatives. Past challenges have spurred advances in robotics, additive manufacturing, power and energy, textiles, chemistry, and biology.
Mars to Table is a collaborative, cross-program Centennial Challenge with support from NASA’s Division of Biological and Physical Sciences, Heliophysics Division, Planetary Science Program, Human Research Program, and Mars Campaign Office. Subject matter experts at the agency’s Johnson Space Center in Houston and Kennedy Space Center in Florida support the challenge. This challenge is part of the Prizes, Challenges and Crowdsourcing program within NASA’s Space Technology Mission Directorate. NASA has partnered with the Methuselah Foundation and contracted Floor23 Digital to support the administration and management of this challenge.

A bright reflection nebula shares the stage with a protostar and planet-forming disk in this Hubble image.

A disparate collection of young stellar objects bejewels a cosmic panorama in the star-forming region NGC 1333 in this new image from NASA’s Hubble Space Telescope. To the left, an actively forming star called a protostar casts its glow on the surrounding gas and dust, creating a reflection nebula. Two dark stripes on opposite sides of the bright point (upper left) are its protoplanetary disk, a region where planets could form, and the disk’s shadow, cast across the large envelope of material around the star. Material accumulates onto the protostar through this rotating disk of gas and dust, a product of the collapsing cloud of gas and dust that gave birth to the star. Where the shadow stops and the disk begins is presently unknown.
To the center right, an outflow cavity reveals a fan-shaped reflection nebula. The two stars at its base, HBC 340 (lower) and HBC 341 (upper), unleash stellar winds, or material flowing from the surface of the star, that clear out the cavity from the surrounding molecular cloud over time. A reflection nebula like this one is illuminated by light from nearby stars that is scattered by the surrounding gas and dust.
This reflection nebula fluctuates in brightness over time, which researchers attribute to variations in brightness of HBC 340 and HBC 341. HBC 340 is the primary source of the fluctuation as the brighter and more variable star. HBC 340 and HBC 341 are Orion variable stars, a class of forming stars that change in brightness irregularly and unpredictably, possibly due to stellar flares and ejections of matter from their surfaces. Orion variable stars, so named because they are associated with diffuse nebulae like the Orion Nebula, eventually evolve into non-variable stars.
In this image, the four beaming stars near the bottom of the image and one in the top right corner are also Orion variable stars. The rest of the cloudscape is studded with other young stellar objects.
NGC 1333 lies about 950 light-years away in the Perseus molecular cloud, and was imaged by Hubble to learn more about young stellar objects, such as properties of circumstellar disks and outflows in the gas and dust created by these stars.

NASA’s Webb Delivers Unprecedented Look Into Heart of Circinus Galaxy

The Circinus Galaxy, a galaxy about 13 million light-years away, contains an active supermassive black hole that continues to influence its evolution. The largest source of infrared light from the region closest to the black hole itself was thought to be outflows, or streams of superheated matter that fire outward.

Now, new observations by NASA’s James Webb Space Telescope, seen here with a new image from NASA’s Hubble Space Telescope, provide evidence that reverses this thinking, suggesting that most of the hot, dusty material is actually feeding the central black hole. The technique used to gather this data also has the potential to analyze the outflow and accretion components for other nearby black holes.
The research, which includes the sharpest image of a black hole’s surroundings ever taken by Webb, published Tuesday in Nature.
Outflow question
Supermassive black holes like those in Circinus remain active by consuming surrounding matter. Infalling gas and dust accumulates into a donut-shaped ring around the black hole, known as a torus. As supermassive black holes gather matter from the torus’ inner walls, they form an accretion disk, similar to a whirlpool of water swirling around a drain. This disk grows hotter through friction, eventually becoming hot enough to emit light.
This glowing matter can become so bright that resolving details within the galaxy’s center with ground-based telescopes is difficult. It’s made even harder due to the bright, concealing starlight within Circinus. Further, since the torus is incredibly dense, the inner region of the infalling material, heated by the black hole, is obscured from our point of view. For decades, astronomers contended with these difficulties, designing and improving models of Circinus with as much data as they could gather.

“In order to study the supermassive black hole, despite being unable to resolve it, they had to obtain the total intensity of the inner region of the galaxy over a large wavelength range and then feed that data into models,” said lead author Enrique Lopez-Rodriguez of the University of South Carolina.
Early models would fit the spectra from specific regions, such as the emissions from the torus, those of the accretion disk closest to the black hole, or those from the outflows, each detected at certain wavelengths of light. However, since the region could not be resolved in its entirety, these models left questions at several wavelengths. For example, some telescopes could detect an excess of infrared light, but lacked the resolution to determine where exactly it was coming from.
“Since the ‘90s, it has not been possible to explain excess infrared emissions that come from hot dust at the cores of active galaxies, meaning the models only take into account either the torus or the outflows, but cannot explain that excess,” said Lopez-Rodriguez.
Such models found that most of the emission (and, therefore, mass) close to the center came from outflows. To test this theory, then, astronomers needed two things: the ability to filter the starlight that previously prevented a deeper analysis, and the ability to distinguish the infrared emissions of the torus from those of the outflows. Webb, sensitive and technologically sophisticated enough to meet both challenges, was necessary to advance our understanding.
Webb’s innovative technique
To look into the center of Circinus, Webb needed the Aperture Masking Interferometer tool on its NIRISS (Near-Infrared Imager and Slitless Spectrograph) instrument.
On Earth, interferometers usually take the form of telescope arrays: mirrors or antennae that work together as if they were a single telescope. An interferometer does this by gathering and combining the light from whichever source it is pointed toward, causing the electromagnetic waves that make up light to “interfere” with each other (hence, “interfere-ometer”) and creating interference patterns. These patterns can be analyzed by astronomers to reconstruct the size, shape, and features of distant objects with much greater detail than non-interferometric techniques.
The Aperture Masking Interferometer allows Webb to become an array of smaller telescopes working together as an interferometer, creating these interference patterns by itself. It does this by utilizing a special aperture made of seven small, hexagonal holes, which, like in photography, controls the amount and direction of light that enters the telescope’s detectors.
“These holes in the mask are transformed into small collectors of light that guide the light toward the detector of the camera and create an interference pattern,” said Joel Sanchez-Bermudez, co-author based at the National University of Mexico.
With new data in hand, the research team was able to construct an image from the central region’s interference patterns. To do so, they referenced data from previous observations to ensure their data from Webb was free of any artifacts. This resulted in the first extragalactic observation from an infrared interferometer in space.
“By using an advanced imaging mode of the camera, we can effectively double its resolution over a smaller area of the sky,” Sanchez-Bermudez said. “This allows us to see images twice as sharp. Instead of Webb’s 6.5-meter diameter, it’s like we are observing this region with a 13-meter space telescope.”
The data showed that contrary to the models predicting that the infrared excess comes from the outflows, around 87% of the infrared emissions from hot dust in Circinus come from the areas closest to the black hole, while less than 1% of emissions come from hot dusty outflows. The remaining 12% comes from distances farther away that could not previously be told apart.
“It is the first time a high-contrast mode of Webb has been used to look at an extragalactic source,” said Julien Girard, paper co-author and senior research scientist at the Space Telescope Science Institute. “We hope our work inspires other astronomers to use the Aperture Masking Interferometer mode to study faint, but relatively small, dusty structures in the vicinity of any bright object.”

While the mystery of Circinus’ excess emissions has been solved, there are billions of black holes in our universe. Those of different luminosities, the team notes, may have an influence on whether most of the emissions come from a black hole’s torus or their outflows.
“The intrinsic brightness of Circinus’ accretion disk is very moderate,” Lopez-Rodriguez said. “So it makes sense that the emissions are dominated by the torus. But maybe, for brighter black holes, the emissions are dominated by the outflow.”
With this research, astronomers now have a tested technique to investigate whichever black holes they want, so long as they are bright enough for the Aperture Masking Interferometer to be useful. Studying additional targets will be essential to building a catalog of emission data to figure out if Circinus’ results were unique or characteristic of a pattern.
“We need a statistical sample of black holes, perhaps a dozen or two dozen, to understand how mass in their accretion disks and their outflows relate to their power,” Lopez-Rodriguez said.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

Before and After
Hurricane Melissa made landfall in Jamaica on October 28, 2025, as a category 5 storm, bringing sustained winds of 295 kilometers (185 miles) per hour and leaving a broad path of destruction on the island. The storm displaced tens of thousands of people, damaged or destroyed more than 100,000 structures, inflicted costly damage on farmland, and left the nation’s forests brown and battered.
Prior to landfall, in the waters south of the island, the hurricane created a large-scale natural oceanography experiment. Before encountering land and proceeding north, the monster storm crawled over the Caribbean Sea, churning up the water below. A couple of days later, a break in the clouds revealed what researchers believe could be a once-in-a-century event.
On October 30, 2025, the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument on NASA’s Terra satellite acquired this image (right) of the waters south of Jamaica. Vast areas are colored bright blue by sediment stirred up from a carbonate platform called Pedro Bank. This plateau, submerged under about 25 meters (80 feet) of water, is slightly larger in area than the state of Delaware. For comparison, the left image was acquired by the same sensor on September 20, before the storm.
Pedro Bank is deep enough that it is only faintly visible in natural color satellite images most of the time. However, with enough disruption from hurricanes or strong cold fronts, its existence becomes more evident to satellites. Suspended calcium carbonate (CaCO3) mud, consisting primarily of remnants of marine organisms that live on the plateau, turns the water a Maya blue color. The appearance of this type of material contrasts with the greenish-brown color of sediment carried out to sea by swollen rivers on Jamaica’s southern coast.
As an intense storm that lingered in the vicinity of the bank, Hurricane Melissa generated “tremendous stirring power” in the water column, said James Acker, a data support scientist at the NASA Goddard Earth Sciences Data and Information Services Center with a particular interest in these events. Hurricane Beryl caused some brightening around Pedro Bank in July 2024, “but nothing like this,” he said. “While we always have to acknowledge the human cost of a disaster, this is an extraordinary geophysical image.”
Sediment suspension was visible on Pedro and other nearby shallow banks, indicating that Melissa affected a total area of about 37,500 square kilometers—more than three times the area of Jamaica—on October 30, said sedimentologist Jude Wilber, who tracked the plume’s progression using multiple satellite sensors. Having studied carbonate sediment transport for decades, he believes the Pedro Bank event was the largest observed in the satellite era. “It was extraordinary to see the sediment dispersed over such a large area,” he said.
The sediment acted as a tracer, illuminating currents and eddies near the surface. Some extended into the flow field of the Caribbean Current heading west and north, while other patterns suggested the influence of Ekman transport, Wilber said. The scientists also noted complexities in the south-flowing plume, which divided into three parts after encountering several small reefs. Sinking sediment in the easternmost arm exhibited a cascading stair-step pattern.
Like in other resuspension events, the temporary coloration of the water faded after about seven days as sediment settled. But changes to Pedro Bank itself may be more long-lasting. “I suspect this hurricane was so strong that it produced what I would call a ‘wipe’ of the benthic ecosystem,” Wilber said. Seagrasses, algae, and other organisms living on and around the bank were likely decimated, and it is unknown how repopulation of the area will unfold.
Sediments from the top of Pedro Bank contain masses of calcified red algae, flaky sands made of Halimeda macroalgae remnants, and carbonate mud. The wing-like shape of Halimeda sand allows it to be lifted and transported while waters are turbulent, and finer mud remains suspended longer. These samples were acquired during a research expedition in the winter of 1987-1988 and are archived at the Woods Hole Oceanographic Institution.

Perhaps most consequentially for Earth’s oceans, however, is the effect of the sediment suspension event on the planet’s carbon cycle. Tropical cyclones are an important way for carbon in shallow-water marine sediments to reach deeper waters, where it can remain sequestered for the long term. At depth, carbonate sediments will also dissolve, another important process in the oceanic carbon system.
Near-continuous ocean observations by satellites have enabled greater understanding of these events and their carbon cycling. Acker and Wilber have worked on remote-sensing methods to quantify how much sediment reaches the deep ocean following the turbulence of tropical cyclones, including recently with Hurricane Ian over the West Florida Shelf. Now, hyperspectral observations from NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission, launched in February 2024, are poised to build on that progress, Acker said.
The phenomenon at Pedro Bank following Hurricane Melissa provided a singular opportunity to study this and other complex ocean processes—a large natural experiment that could not be accomplished any other way. Researchers will be further investigating a range of physical, geochemical, and biological aspects illuminated by this occurrence. As Wilber put it: “This event is a whole course in oceanography.”
