The Mass Spectrometer Observing Lunar Operations (MSolo) for NASA’s Volatile Investigating Polar Exploration Rover (VIPER) mission is prepared for packing inside a laboratory in the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on Feb. 21, 2023. MSolo is a commercial off-the-shelf mass spectrometer modified to work in space and it will help analyze the chemical makeup of landing sites on the Moon, as well as study water on the lunar surface.NASA/Kim Shiflett A NASA-developed technology that recently proved its capabilities in the harsh environment of space will soon head back to the Moon to search for gases trapped under the lunar surface thanks to a new Cooperative Research and Development Agreement between NASA and commercial company Magna Petra Corp.
The Mass Spectrometer Observing Lunar Operations (MSOLO) successfully demonstrated the full range of its hardware in lunar conditions during the Intuitive Machines 2 mission earlier this year. Under the new agreement, a second MSOLO, mounted on a commercial rover, will launch to the Moon no earlier than 2026. Once on the lunar surface, it will measure low molecular weight volatiles in hopes of inferring the presence of rare isotopes, such as Helium-3, which is theorized to exist, trapped in the regolith, or lunar dust, of the Moon.
“This new mission opportunity will help us determine what volatiles are present in the lunar surface, while also providing scientific insight for Magna Petra’s goals,” said Roberto Aguilar Ayala, research physicist at NASA’s Kennedy Space Center in Florida. “Learning more about the lunar volatiles and their isotopes supports NASA’s goal of sustaining long-term human space exploration. We will need to extract resources locally to enhance the capabilities of our astronauts to further exploration opportunities on the lunar surface.”
The MSOLO instrument will be integrated on a commercial rover, selected by Magna Petra. The rover will allow MSOLO to gather the data needed for researchers to understand which low-molecular weight gases reside within the Moon’s surface.
NASA will work with the partner to integrate MSOLO so that it will function properly with the rover, and the partner will analyze and share data in real time with NASA to understand the location of these volatiles on the Moon and their ability to be extracted in the future.
Magna Petra hopes to understand the presence of Helium-3 isotope within the Moon’s surface, with the ultimate goal of collecting it and bringing it back to Earth for use in a variety of industries, including energy production through nuclear fusion, quantum computing, health care, and specialized laboratory equipment.
The MSOLO instrument began as a commercial off-the-shelf mass spectrometer designed to analyze volatiles used in the manufacturing of semi-conductors, which helped keep NASA’s development costs down. NASA modified the device to withstand the rigors of spaceflight and the Moon’s harsh conditions. On its first journey to the Moon, MSOLO was part of the Polar Resources Ice Mining Experiment 1.
Signed on April 2, the reimbursable agreement is the first of its kind established at NASA Kennedy. Under the agreement, Magna Petra will reimburse NASA for costs such as supporting MSOLO integration and testing with the rover, pre-mission preparation and mission operations of the instruments, and expertise in system engineering, avionics, and software.
“This innovative agreement promises to provide valuable data to both partners,” said Jonathan Baker, chief of Spaceport Development at NASA Kennedy. “This approach demonstrates NASA’s commitment to finding unique ways to work with commercial industry to help advance technology in a fiscally responsible way and enabling innovation for the benefit of humankind.”
Throughout the mission, NASA will retain ownership of MSOLO. Once the mission is complete, the instrument will no longer have access to power and communications and will remain on the surface of the Moon. The valuable data gathered during the mission will be submitted to the Planetary Data System for public dissemination.

NASA’s James Webb Space Telescope’s observations of what is thought to be the first-ever recorded planetary engulfment event revealed a hot accretion disk surrounding the star, with an expanding cloud of cooler dust enveloping the scene. Webb also revealed that the star did not swell to swallow the planet, but the planet’s orbit actually slowly depreciated over time, as seen in this artist’s concept. Full illustration below. Credits:
NASA, ESA, CSA, R. Crawford (STScI) Observations from NASA’s James Webb Space Telescope have provided a surprising twist in the narrative surrounding what is believed to be the first star observed in the act of swallowing a planet. The new findings suggest that the star actually did not swell to envelop a planet as previously hypothesized. Instead, Webb’s observations show the planet’s orbit shrank over time, slowly bringing the planet closer to its demise until it was engulfed in full.
“Because this is such a novel event, we didn’t quite know what to expect when we decided to point this telescope in its direction,” said Ryan Lau, lead author of the new paper and astronomer at NSF NOIRLab (National Science Foundation National Optical-Infrared Astronomy Research Laboratory) in Tuscon, Arizona. “With its high-resolution look in the infrared, we are learning valuable insights about the final fates of planetary systems, possibly including our own.”
Two instruments aboard Webb conducted the post-mortem of the scene – Webb’s MIRI (Mid-Infrared Instrument) and NIRSpec (Near-Infrared Spectrograph). The researchers were able to come to their conclusion using a two-pronged investigative approach.

Crawford (STScI) Constraining the How
The star at the center of this scene is located in the Milky Way galaxy about 12,000 light-years away from Earth.
The brightening event, formally called ZTF SLRN-2020, was originally spotted as a flash of optical light using the Zwicky Transient Facility at the Palomar Observatory in San Diego, California. Data from NASA’s NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer) showed the star actually brightened in the infrared a year before the optical light flash, hinting at the presence of dust. This initial 2023 investigation led researchers to believe that the star was more Sun-like, and had been in the process of aging into a red giant over hundreds of thousands of years, slowly expanding as it exhausted its hydrogen fuel.
However, Webb’s MIRI told a different story. With powerful sensitivity and spatial resolution, Webb was able to precisely measure the hidden emission from the star and its immediate surroundings, which lie in a very crowded region of space. The researchers found the star was not as bright as it should have been if it had evolved into a red giant, indicating there was no swelling to engulf the planet as once thought.
Reconstructing the Scene
Researchers suggest that, at one point, the planet was about Jupiter-sized, but orbited quite close to the star, even closer than Mercury’s orbit around our Sun. Over millions of years, the planet orbited closer and closer to the star, leading to the catastrophic consequence.
“The planet eventually started to graze the star’s atmosphere. Then it was a runaway process of falling in faster from that moment,” said team member Morgan MacLeod of the Harvard-Smithsonian Center for Astrophysics and the Massachusetts Institute of Technology in Cambridge, Massachusetts. “The planet, as it’s falling in, started to sort of smear around the star.”
In its final splashdown, the planet would have blasted gas away from the outer layers of the star. As it expanded and cooled off, the heavy elements in this gas condensed into cold dust over the next year.
Inspecting the Leftovers
While the researchers did expect an expanding cloud of cooler dust around the star, a look with the powerful NIRSpec revealed a hot circumstellar disk of molecular gas closer in. Furthermore, Webb’s high spectral resolution was able to detect certain molecules in this accretion disk, including carbon monoxide.
“With such a transformative telescope like Webb, it was hard for me to have any expectations of what we’d find in the immediate surroundings of the star,” said Colette Salyk of Vassar College in Poughkeepsie, New York, an exoplanet researcher and co-author on the new paper. “I will say, I could not have expected seeing what has the characteristics of a planet-forming region, even though planets are not forming here, in the aftermath of an engulfment.”
The ability to characterize this gas opens more questions for researchers about what actually happened once the planet was fully swallowed by the star.
“This is truly the precipice of studying these events. This is the only one we’ve observed in action, and this is the best detection of the aftermath after things have settled back down,” Lau said. “We hope this is just the start of our sample.”
These observations, taken under Guaranteed Time Observation program 1240, which was specifically designed to investigate a family of mysterious, sudden, infrared brightening events, were among the first Target of Opportunity programs performed by Webb. These types of study are reserved for events, like supernova explosions, that are expected to occur, but researchers don’t exactly know when or where. NASA’s space telescopes are part of a growing, international network that stands ready to witness these fleeting changes, to help us understand how the universe works.
Researchers expect to add to their sample and identify future events like this using the upcoming Vera C. Rubin Observatory and NASA’s Nancy Grace Roman Space Telescope, which will survey large areas of the sky repeatedly to look for changes over time.
The team’s findings appear today in The Astrophysical Journal.
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).

Hubble Studies a Nearby Galaxy’s Star Formation
This NASA/ESA Hubble Space Telescope image features the picturesque spiral galaxy NGC 4941. ESA/Hubble & NASA, D. Thilker This NASA/ESA Hubble Space Telescope image features the picturesque spiral galaxy NGC 4941, which lies about 67 million light-years from Earth in the constellation Virgo (The Maiden). Because this galaxy is nearby, cosmically speaking, Hubble’s keen instruments are able to pick out exquisite details such as individual star clusters and filamentary clouds of gas and dust.
The data used to construct this image were collected as part of an observing program that investigates the star formation and stellar feedback cycle in nearby galaxies. As stars form in dense, cold clumps of gas, they begin to influence their surroundings. Stars heat and stir up the gas clouds in which they form through winds, starlight, and — eventually, for massive stars — by exploding as supernovae. These processes are collectively called stellar feedback, and they influence the rate at which a galaxy can form new stars.
As it turns out, stars aren’t the only entities providing feedback in NGC 4941. At the heart of this galaxy lies an active galactic nucleus: a supermassive black hole feasting on gas. As the black hole amasses gas from its surroundings, the gas swirls into a superheated disk that glows brightly at wavelengths across the electromagnetic spectrum. Similar to stars — but on a much, much larger scale — active galactic nuclei shape their surroundings through winds, radiation, and powerful jets, altering not only star formation but also the evolution of the galaxy as a whole.
