Credit: NASA The Trump-Vance Administration released toplines of the President’s budget for Fiscal Year 2026 on Friday. The budget accelerates human space exploration of the Moon and Mars with a fiscally responsible portfolio of missions.
“This proposal includes investments to simultaneously pursue exploration of the Moon and Mars while still prioritizing critical science and technology research,” said acting NASA Administrator Janet Petro. “I appreciate the President’s continued support for NASA’s mission and look forward to working closely with the administration and Congress to ensure we continue making progress toward achieving the impossible.”
Increased commitment to human space exploration in pursuit of exploration of both the Moon and Mars. By allocating more than $7 billion for lunar exploration and introducing $1 billion in new investments for Mars-focused programs, the budget ensures America’s human space exploration efforts remain unparalleled, innovative, and efficient. Refocus science and space technology resources to efficiently execute high priority research. Consistent with the administration’s priority of returning to the Moon before China and putting an American on Mars, the budget will advance priority science and research missions and projects, ending financially unsustainable programs including Mars Sample Return. It emphasizes investments in transformative space technologies while responsibly shifting projects better suited for private sector leadership. Transition the Artemis campaign to a more sustainable, cost-effective approach to lunar exploration. The SLS (Space Launch System) rocket and Orion capsule will be retired after Artemis III, paving the way for more cost-effective, next-generation commercial systems that will support subsequent NASA lunar missions. The budget also ends the Gateway Program, with the opportunity to repurpose already produced components for use in other missions. International partners will be invited to join these renewed efforts, expanding opportunities for meaningful collaboration on the Moon and Mars. Continue the process of transitioning the International Space Station to commercial replacements in 2030, focusing onboard research on efforts critical to the exploration of the Moon and Mars. The budget reflects the upcoming transition to a more cost-effective, open commercial approach to human activities in low Earth orbit by reducing the space station’s crew size and onboard research, preparing for the safe decommissioning of the station and its replacement by commercial space stations. Work to minimize duplication of efforts and most efficiently steward the allocation of American taxpayer dollars. This budget ensures NASA’s topline enables a financially sustainable trajectory to complete groundbreaking research and execute the agency’s bold mission. Focus NASA’s resources on its core mission of space exploration. This budget ends climate-focused “green aviation” spending while protecting the development of technologies with air traffic control and other U.S. government and commercial applications, producing savings. This budget also will ensure continued elimination any funding toward misaligned DEIA initiatives, instead designating that money to missions capable of advancing NASA’s core mission. NASA will continue to inspire the next generation of explorers through exciting, ambitious space missions that demonstrate American leadership in space. NASA will coordinate closely with its partners to execute these priorities and investments as efficiently and effectively as possible.
Building on the President’s promise to increase efficiency this budget pioneers a focused, innovative, and fiscally-responsible path to America’s next great era of human space exploration.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s SPHEREx mission is observing the entire sky in 102 infrared colors, or wavelengths of light not visible to the human eye. This image shows a section of sky in one wavelength (3.29 microns), revealing a cloud of dust made of a molecule similar to soot or smoke.NASA/JPL-Caltech This image from NASA’s SPHEREx shows the same region of space in a different infrared wavelength (0.98 microns), but the dust cloud is no longer visible. The molecules that compose the dust — polycyclic aromatic hydrocarbons — do not radiate light in this color.NASA/JPL-Caltech After weeks of preparation, the space observatory has begun its science mission, taking about 3,600 unique images per day to create a map of the cosmos like no other.
Launched on March 11, NASA’s SPHEREx space observatory has spent the last six weeks undergoing checkouts, calibrations, and other activities to ensure it is working as it should. Now it’s mapping the entire sky — not just a large part of it — to chart the positions of hundreds of millions of galaxies in 3D to answer some big questions about the universe. On May 1, the spacecraft began regular science operations, which consist of taking about 3,600 images per day for the next two years to provide new insights about the origins of the universe, galaxies, and the ingredients for life in the Milky Way.
This video shows SPHEREx’s field of view as it scans across one section of sky inside the Large Magellanic Cloud, with rainbow colors representing the infrared wavelengths the telescope’s detectors see. The view from one detector array moves from purple to green, followed by the second array’s view, which changes from yellow to red. The images are looped four times. NASA/JPL-Caltech “Thanks to the hard work of teams across NASA, industry, and academia that built this mission, SPHEREx is operating just as we’d expected and will produce maps of the full sky unlike any we’ve had before,” said Shawn Domagal-Goldman, acting director of the Astrophysics Division at NASA Headquarters in Washington. “This new observatory is adding to the suite of space-based astrophysics survey missions leading up to the launch of NASA’s Nancy Grace Roman Space Telescope. Together with these other missions, SPHEREx will play a key role in answering the big questions about the universe we tackle at NASA every day.”
From its perch in Earth orbit, SPHEREx peers into the darkness, pointing away from the planet and the Sun. The observatory will complete more than 11,000 orbits over its 25 months of planned survey operations, circling Earth about 14½ times a day. It orbits Earth from north to south, passing over the poles, and each day it takes images along one circular strip of the sky. As the days pass and the planet moves around the Sun, SPHEREx’s field of view shifts as well so that after six months, the observatory will have looked out into space in every direction.
When SPHEREx takes a picture of the sky, the light is sent to six detectors that each produces a unique image capturing different wavelengths of light. These groups of six images are called an exposure, and SPHEREx takes about 600 exposures per day. When it’s done with one exposure, the whole observatory shifts position — the mirrors and detectors don’t move as they do on some other telescopes. Rather than using thrusters, SPHEREx relies on a system of reaction wheels, which spin inside the spacecraft to control its orientation.
Hundreds of thousands of SPHEREx’s images will be digitally woven together to create four all-sky maps in two years. By mapping the entire sky, the mission will provide new insights about what happened in the first fraction of a second after the big bang. In that brief instant, an event called cosmic inflation caused the universe to expand a trillion-trillionfold.
“We’re going to study what happened on the smallest size scales in the universe’s earliest moments by looking at the modern universe on the largest scales,” said Jim Fanson, the mission’s project manager at NASA’s Jet Propulsion Laboratory in Southern California. “I think there’s a poetic arc to that.”
Cosmic inflation subtly influenced the distribution of matter in the universe, and clues about how such an event could happen are written into the positions of galaxies across the universe. When cosmic inflation began, the universe was smaller than the size of an atom, but the properties of that early universe were stretched out and influence what we see today. No other known event or process involves the amount of energy that would have been required to drive cosmic inflation, so studying it presents a unique opportunity to understand more deeply how our universe works.
“Some of us have been working toward this goal for 12 years,” said Jamie Bock, the mission’s principal investigator at Caltech and JPL. “The performance of the instrument is as good as we hoped. That means we’re going to be able to do all the amazing science we planned on and perhaps even get some unexpected discoveries.”
Color Field
The SPHEREx observatory won’t be the first to map the entire sky, but it will be the first to do so in so many colors. It observes 102 wavelengths, or colors, of infrared light, which are undetectable to the human eye. Through a technique called spectroscopy, the telescope separates the light into wavelengths — much like a prism creates a rainbow from sunlight — revealing all kinds of information about cosmic sources.
For example, spectroscopy can be harnessed to determine the distance to a faraway galaxy, information that can be used to turn a 2D map of those galaxies into a 3D one. The technique will also enable the mission to measure the collective glow from all the galaxies that ever existed and see how that glow has changed over cosmic time.
And spectroscopy can reveal the composition of objects. Using this capability, the mission is searching for water and other key ingredients for life in these systems in our galaxy. It’s thought that the water in Earth’s oceans originated as frozen water molecules attached to dust in the interstellar cloud where the Sun formed.
The SPHEREx mission will make over 9 million observations of interstellar clouds in the Milky Way, mapping these materials across the galaxy and helping scientists understand how different conditions can affect the chemistry that produced many of the compounds found on Earth today.
More About SPHEREx
The SPHEREx mission is managed by JPL for the agency’s Astrophysics Division within the Science Mission Directorate at NASA Headquarters. BAE Systems in Boulder, Colorado, 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 in the U.S., two in South Korea, and one in Taiwan. Caltech in Pasadena managed and integrated the instrument. The mission’s principal investigator is based at Caltech with a joint JPL appointment. Data will be processed and archived at IPAC at Caltech. The SPHEREx dataset will be publicly available at the NASA-IPAC Infrared Science Archive. Caltech manages JPL for NASA.

This artist’s concept depicts a magnetar – a type of neutron star with a strong magnetic field – losing material into space. Shown as thin green lines, the magnetic field lines influence the movement of charged material around the magnetar. NASA/JPL-Caltech Since the big bang, the early universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in stars. But one of the biggest mysteries in astrophysics is: How did the first elements heavier than iron, such as gold, get created and distributed throughout the universe?
“It’s a pretty fundamental question in terms of the origin of complex matter in the universe,” said Anirudh Patel, a doctoral student at Columbia University in New York. “It’s a fun puzzle that hasn’t actually been solved.”
Patel led a study using 20-year-old archival data from NASA and ESA telescopes that finds evidence for a surprising source of a large amount of these heavy elements: flares from highly magnetized neutron stars, called magnetars. The study is published in The Astrophysical Journal Letters.
Study authors estimate that magnetar giant flares could contribute up to 10% of the total abundance of elements heavier than iron in the galaxy. Since magnetars existed relatively early in the history of the universe, the first gold could have been made this way.
“It’s answering one of the questions of the century and solving a mystery using archival data that had been nearly forgotten,” said Eric Burns, study co-author and astrophysicist at Louisiana State University in Baton Rouge.
How could gold be made at a magnetar?
Neutron stars are the collapsed cores of stars that have exploded. They are so dense that one teaspoon of neutron star material, on Earth, would weigh as much as a billion tons. A magnetar is a neutron star with an extremely powerful magnetic field.
On rare occasions, magnetars release an enormous amount of high-energy radiation when they undergo “starquakes,” which, like earthquakes, fracture the neutron star’s crust. Starquakes may also be associated with powerful bursts of radiation called magnetar giant flares, which can even affect Earth’s atmosphere. Only three magnetar giant flares have been observed in the Milky Way and the nearby Large Magellanic Cloud, and seven outside.
Patel and colleagues, including his advisor Brian Metzger, professor at Columbia University and senior research scientist at the Flatiron Institute in New York, have been thinking about how radiation from giant flares could correspond to heavy elements forming there. This would happen through a “rapid process” of neutrons forging lighter atomic nuclei into heavier ones.
Protons define the element’s identity on the periodic table: hydrogen has one proton, helium has two, lithium has three, and so on. Atoms also have neutrons which do not affect identity, but do add mass. Sometimes when an atom captures an extra neutron the atom becomes unstable and a nuclear decay process happens that converts a neutron into a proton, moving the atom forward on the periodic table. This is how, for example, a gold atom could take on an extra neutron and then transform into mercury.
In the unique environment of a disrupted neutron star, in which the density of neutrons is extremely high, something even stranger happens: single atoms can rapidly capture so many neutrons that they undergo multiple decays, leading to the creation of a much heavier element like uranium.
When astronomers observed the collision of two neutron stars in 2017 using NASA telescopes and the Laser Interferomete Gravitational wave Observatory (LIGO), and numerous telescopes on the ground and in space that followed up the initial discovery, they confirmed that this event could have created gold, platinum, and other heavy elements. But neutron star mergers happen too late in the universe’s history to explain the earliest gold and other heavy elements. Recent research by co-authors of the new study — Jakub Cehula of Charles University in Prague, Todd Thompson of The Ohio State University, and Metzger — has found that magnetar flares can heat and eject neutron star crustal material at high speeds, making them a potential source.

At first, Metzger and colleagues thought that the signature from the creation and distribution of heavy elements at a magnetar would appear in the visible and ultraviolet light, and published their predictions. But Burns in Louisiana wondered if there could be a gamma-ray signal bright enough to be detected, too. He asked Metzger and Patel to check, and they found that there could be such a signature.
“At some point, we said, ‘OK, we should ask the observers if they had seen any,’” Metzger said.
Burns looked up the gamma ray data from the last giant flare that has been observed, which was in December 2004. He realized that while scientists had explained the beginning of the outburst, they had also identified a smaller signal from the magnetar, in data from ESA (European Space Agency)’s INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL), a recently retired mission with NASA contributions. “It was noted at the time, but nobody had any conception of what it could be,” Burns said.
Metzger remembers that Burns thought he and Patel were “pulling his leg” because the prediction from their team’s model so closely matched the mystery signal in the 2004 data. In other words, the gamma ray signal detected over 20 years ago corresponded to what it should look like when heavy elements are created and then distributed in a magnetar giant flare.
Patel was so excited, “I wasn’t thinking about anything else for the next week or two. It was the only thing on my mind,” he said.
Researchers supported their conclusion using data from two NASA heliophysics missions: the retired RHESSI (Reuven Ramaty High Energy Solar Spectroscopic Imager) and the ongoing NASA’s Wind satellite, which had also observed the magnetar giant flare. Other collaborators on the new study included Jared Goldberg at the Flatiron Institute.
Next steps in the magnetar gold rush
NASA’s forthcoming COSI (Compton Spectrometer and Imager) mission can follow up on these results. A wide-field gamma ray telescope, COSI is expected to launch in 2027 and will study energetic phenomena in the cosmos, such as magnetar giant flares. COSI will be able to identify individual elements created in these events, providing a new advancement in understanding the origin of the elements. It is one of many telescopes that can work together to look for “transient” changes across the universe.
Researchers will also follow up on other archival data to see if other secrets are hiding in observations of other magnetar giant flares.
“It very cool to think about how some of the stuff in my phone or my laptop was forged in this extreme explosion of the course of our galaxy’s history,” Patel said.

5 Min Read NASA 3D Wind Measuring Laser Aims to Improve Forecasts from Air, Space
3D wind measurements from NASA's Aerosol Wind Profiler instrument flying on board a specially mounted aircraft along the East Coast of the U.S. and across the Great Lakes region on Oct. 15, 2024. Credits: NASA/Scientific Visualization Studio Since last fall, NASA scientists have flown an advanced 3D Doppler wind lidar instrument across the United States to collect nearly 100 hours of data — including a flight through a hurricane. The goal? To demonstrate the unique capability of the Aerosol Wind Profiler (AWP) instrument to gather extremely precise measurements of wind direction, wind speed, and aerosol concentration – all crucial elements for accurate weather forecasting.
Weather phenomena like severe thunderstorms and hurricanes develop rapidly, so improving predictions requires more accurate wind observations.
“There is a lack of global wind measurements above Earth’s surface,” explained Kris Bedka, the AWP principal investigator at NASA’s Langley Research Center in Hampton, Virginia. “Winds are measured by commercial aircraft as they fly to their destinations and by weather balloons launched up to twice per day from just 1,300 sites across the globe. From space, winds are estimated by tracking cloud and water vapor movement from satellite images.”
However, in areas without clouds or where water vapor patterns cannot be easily tracked, there are typically no reliable wind measurements. The AWP instrument seeks to fill these gaps with detailed 3D wind profiles.
The AWP instrument (foreground) and HALO instrument (background) was integrated onto the floorboard of NASA’s G-III aircraft. Kris Bedka, project principal investigator, sitting in the rear of the plane, monitored the data during a flight on Sept. 26, 2024. NASA/Maurice Cross Mounted to an aircraft with viewing ports underneath it, AWP emits 200 laser energy pulses per second that scatter and reflect off aerosol particles — such as pollution, dust, smoke, sea salt, and clouds — in the air. Aerosol and cloud particle movement causes the laser pulse wavelength to change, a concept known as the Doppler effect.
The AWP instrument sends these pulses in two directions, oriented 90 degrees apart from each other. Combined, they create a 3D profile of wind vectors, representing both wind speed and direction.
We are measuring winds at different altitudes in the atmosphere simultaneously with extremely high detail and accuracy.

“The Aerosol Wind Profiler is able to measure wind speed and direction, but not just at one given point,” Bedka said. “Instead, we are measuring winds at different altitudes in the atmosphere simultaneously with extremely high detail and accuracy.”
Vectors help researchers and meteorologists understand the weather, so AWP’s measurements could significantly advance weather modeling and forecasting. For this reason, the instrument was chosen to be part of the National Oceanic and Atmospheric Administration’s (NOAA) Joint Venture Program, which seeks data from new technologies that can fill gaps in current weather forecasting systems. NASA’s Weather Program also saw mutual benefit in NOAA’s investments and provided additional support to increase the return on investment for both agencies.
On board NASA’s Gulfstream III (G-III) aircraft, AWP was paired with the agency’s High-Altitude Lidar Observatory (HALO) that measures water vapor, aerosols, and cloud properties through a combined differential absorption and high spectral resolution lidar.
Working together for the first time, AWP measured winds, HALO collected water vapor and aerosol data, and NOAA dropsondes (small instruments dropped from a tube in the bottom of the aircraft) gathered temperature, water vapor, and wind data.

NASA/Maurice Cross “With our instrument package on board small, affordable-to-operate aircraft, we have a very powerful capability,” said Bedka. “The combination of AWP and HALO is NASA’s next-generation airborne weather remote sensing package, which we hope to also fly aboard satellites to benefit everyone across the globe.”

The animation below, based on AWP data, shows the complexity and structure of aerosol layers present in the atmosphere. Current prediction models do not accurately simulate how aerosols are organized throughout the breadth of the atmosphere, said Bedka.

This visualization shows AWP 3D measurements gathered on Oct. 15, 2024, as NASA’s G-III aircraft flew along the East Coast of the U.S. and across the Great Lakes region. Laser light that returns to AWP as backscatter from aerosol particles and clouds allows for measurement of wind direction, speed, and aerosol concentration as seen in the separation of data layers. NASA/Scientific Visualization Studio “When we took off on this particular day, I thought that we would be finding a clear atmosphere with little to no aerosol return because we were flying into what was the first real blast of cool Canadian air of the fall,” described Bedka. “What we found was quite the opposite: an aerosol-rich environment which provided excellent signal to accurately measure winds.”
During the Joint Venture flights, Hurricane Helene was making landfall in Florida. The AWP crew of two pilots and five science team members quickly created a flight plan to gather wind measurements along the outer bands of the severe storm.

NASA/Kris Bedka “A 3D wind profile can significantly improve weather forecasts, particularly for storms and hurricanes,” said Harshesh Patel, NOAA’s acting Joint Venture Program manager. “NASA Langley specializes in the development of coherent Doppler wind lidar technology and this AWP concept has potential to provide better performance for NOAA’s needs.”

“The need to improve global 3D wind models requires a space-based platform,” added Patel. “Instruments like AWP have specific space-based applications that potentially align with NOAA’s mission to provide critical data for improving weather forecasting.”

These missions studied atmospheric processes within the planetary boundary layer, the lowest part of the atmosphere, that drives the weather conditions we experience on the ground.
