Preparations for Next Moonwalk Simulations Underway (and Underwater)
Multinational corporations are using the M2M Intelligence platform in data centers and other settings. The system offers automated, secure communications on a ground-based global 5G network. Getty Images Artificial intelligence (AI) is advancing rapidly, as intelligent software proves capable of various tasks. The technology usually requires a “human in the loop” to train it and ensure accuracy. But long before the arrival of today’s generative artificial intelligence, a different kind of AI was born with the help of NASA’s Ames Research Center in California’s Silicon Valley — one that only exists between machines, running without any human intervention.
In 2006, Geoffrey Barnard founded Machine-to-Machine Intelligence Corp. (M2Mi) at Ames’ NASA Research Park, envisioning an automated, satellite-based communication network. NASA Ames established a Space Act Agreement with the company to develop artificial intelligence that would automate communications, privacy, security, and resiliency between satellites and ground-based computers.
Central to the technology was automating a problem-solving approach known as root cause analysis, which NASA has honed over decades. This methodology seeks to identify not only the immediate cause of a problem but also all the factors that contributed to the cause. This would allow a network to identify its own issues and fix itself.
NASA Ames’ director of nanotechnology at the time wanted to develop a communications network based on small, low-powered satellites, so Ames supported M2Mi in developing the necessary technology.
Barnard, now CEO and chief technology officer of Tiburon, California-based branch of M2Mi, said NASA’s support laid the foundation for his company, which employs the same technology in a ground-based network.
The company’s M2M Intelligence software performs secure, resilient, automated communications on a system that runs across hundreds of networks, connecting thousands of devices, many of which were not built to communicate with each other. The M2Mi company worked with Vodafone of Berkshire, England, to build a worldwide network across more than 500 smaller networks in over 190 countries. The companies M2M Wireless and TriGlobal have begun using M2M Intelligence for transportation logistics.
With NASA’s help, emerging industries are getting the boost they need to rapidly develop technologies to enhance our lives.

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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A digital rendering of the baseline configuration for Blue Origin’s free-flying commercial space station, Orbital Reef, which continues to be developed as part of a Space Act Agreement with NASA.Blue Origin A NASA-supported commercial space station, Blue Origin’s Orbital Reef, recently completed a human-in-the-loop testing milestone as the agency works toward developing commercial space stations in low Earth orbit.
The human-in-the-loop test scenarios utilized individual participants or small groups to perform day-in-the-life walkthroughs in life-sized mockups of major station components. Participants provided feedback while simulating microgravity operations, including cargo transfer, trash transfer, stowage, and worksite assessments.
“Human-in-the-loop and iterative testing are essential to inform key decisions and mitigate risks to crew health and safety,” said Angela Hart, program manager for NASA’s Commercial Low Earth Orbit Development Program at the agency’s Johnson Space Center in Houston. “NASA’s insight into our partner’s testing milestones enables the agency to gain insight into partner progress and share expertise, ultimately improving industry and NASA’s mission success.”
Test subjects in the mockup for Blue Origin’s free-flying commercial space station, Orbital Reef, during the human-in-the-loop test.Blue Origin The milestone is part of a NASA Space Act Agreement originally awarded to Blue Origin in 2021 and focused on the design progress for multiple worksites, floors, and translation paths within the station. This ensures a commercial station can support human life, which is critical to advancing scientific research in a microgravity environment and maintaining a continuous human presence in low Earth orbit.
The test evaluated various aspects of Orbital Reef’s environment to provide information needed for the space station’s design. Assessment areas included the private crew quarters, dining area, lavatory, research laboratory, and berthing and docking hatches.
To facilitate the test, Blue Origin built stand-alone mockups of each floor in the internally developed habitable module. These mockups will be iteratively updated as the fidelity of components and subsystems matures, enabling future human-in-the-loop testing.
The research team’s observations will be used to provide design recommendations for worksite volumes, layouts, restraint and mobility aid layouts, usability and workload, and positioning of interfaces and equipment.
NASA supports the design and development of multiple commercial space stations, including Orbital Reef, through funded and unfunded agreements. The current design and development phase will soon be followed by the procurement of services from one or more companies, where NASA aims to be one of many customers for low Earth orbit stations.
NASA is committed to maintaining a continuous human presence in low Earth orbit as the agency transitions from the International Space Station to commercial space stations. For nearly 25 years, NASA has supported a continuous presence in low Earth orbit aboard the space station and will continue to build on the agency’s extensive human spaceflight experience to advance future scientific and exploration goals.

ESA Researchers using NASA’s Hubble Space Telescope have discovered the magnetar called SGR 0501+4516 is traversing our galaxy from an unknown place of origin. Researchers say that this runaway magnetar is the likeliest candidate in our Milky Way galaxy for a magnetar that was not born in a supernova explosion as initially predicted. It is so strange it might even offer clues to the mechanism behind events known as fast radio bursts.
“Magnetars are neutron stars — the dead remnants of stars — composed entirely of neutrons. What makes magnetars unique is their extreme magnetic fields,” said Ashley Chrimes, lead author of the discovery paper published in the April 15 journal Astronomy & Astrophysics. Chrimes is a European Space Agency Research Fellow at the European Space Research and Technology Center in the Netherlands.
Magnetars have comic-book-hero superpowers. A magnetar has a magnetic field about a trillion times more powerful than Earth’s magnetosphere. If a magnetar flew by Earth at half the Moon’s distance, its intense field would wipe out every credit card on our planet. If a human got within 600 miles, the magnetar would become a proverbial sci-fi death-ray, ripping apart every atom inside the body.
The magnetar’s strangeness was identified with the help of Hubble’s sensitive instruments as well as precise benchmarks from ESA’s (European Space Agency) Gaia spacecraft.
Initially, the mysterious magnetar was discovered in 2008 when NASA’s Swift Observatory spotted brief, intense flashes of gamma rays from the outskirts of the Milky Way. The source, which turned out to be one of only about 30 known magnetars in the Milky Way, was dubbed SGR 0501+4516.
This is an artist’s impression of a magnetar, which is a special type of neutron star with an incredibly strong magnetic field. Neutron stars are some of the most compact and extreme objects in the universe. These stars typically pack more than the mass of the Sun into a sphere of neutrons about 12 miles across. The neutron star is depicted as a white-blueish sphere. The magnetic field is shown as filaments streaming out from its polar regions. Illustration: ESA Because magnetars are neutron stars, the natural explanation for their formation is that they are born in supernovae, when a star explodes and can collapse down to an ultra-dense neutron star. This appeared to be the case for SGR 0501+4516, which is located close to a supernova remnant called HB9. The separation between the magnetar and the center of the supernova remnant on the sky is just 80 arcminutes, or slightly wider than your pinky finger when viewed at the end of your outstretched arm.
But a decade-long study with Hubble cast doubt on the magnetar’s birthplace. After initial observations with ground-based telescopes shortly after SGR 0501+4516’s discovery, researchers used Hubble’s exquisite sensitivity and steady pointing to spot the magnetar’s faint infrared glow in 2010, 2012, and 2020. Each of these images was aligned to a reference frame defined by observations from the Gaia spacecraft, which has crafted an extraordinarily precise three-dimensional map of nearly two billion stars in the Milky Way. This method revealed the subtle motion of the magnetar as it traversed the sky.
“All of this movement we measure is smaller than a single pixel of a Hubble image,” said co-investigator Joe Lyman of the University of Warwick, United Kingdom. “Being able to robustly perform such measurements really is a testament to the long-term stability of Hubble.”
By tracking the magnetar’s position, the team was able to measure the object’s apparent motion across the sky. Both the speed and direction of SGR 0501+4516’s movement showed that the magnetar could not be associated with the nearby supernova remnant. Tracing the magnetar’s trajectory thousands of years into the past showed that there were no other supernova remnants or massive star clusters with which it could be associated.
If SGR 0501+4516 was not born in a supernova, the magnetar must either be older than its estimated 20,000-year age, or it may have formed in another way. Magnetars may also be able to form through the merger of two lower-mass neutron stars or through a process called accretion-induced collapse. Accretion-induced collapse requires a binary star system containing a white dwarf: the core of a dead Sun-like star. If the white dwarf pulls in gas from its companion, it can grow too massive to support itself, leading to an explosion — or possibly the creation of a magnetar.
“Normally, this scenario leads to the ignition of nuclear reactions, and the white dwarf exploding, leaving nothing behind. But it has been theorized that under certain conditions, the white dwarf can instead collapse into a neutron star. We think this might be how SGR 0501 was born,” added Andrew Levan of Radboud University in the Netherlands and the University of Warwick in the United Kingdom.
Understanding Fast Radio Bursts
SGR 0501+4516 is currently the best candidate for a magnetar in our galaxy that may have formed through a merger or accretion-induced collapse. Magnetars that form through accretion-induced collapse could provide an explanation for some of the mysterious fast radio bursts, which are brief but powerful flashes of radio waves. In particular, this scenario may explain the origin of fast radio bursts that emerge from stellar populations too ancient to have recently birthed stars massive enough to explode as supernovae.
“Magnetar birth rates and formation scenarios are among the most pressing questions in high-energy astrophysics, with implications for many of the universe’s most powerful transient events, such as gamma-ray bursts, super-luminous supernovae, and fast radio bursts,” said Nanda Rea of the Institute of Space Sciences in Barcelona, Spain.
The research team has further Hubble observations planned to study the origins of other magnetars in the Milky Way, helping to understand how these extreme magnetic objects form.
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.
