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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
https://youtu.be/63uNNcCpxHI How are we made of star stuff?
Well, the important thing to understand about this question is that it’s not an analogy, it’s literally true.
The elements in our bodies, the elements that make up our bones, the trees we see outside, the other planets in the solar system, other stars in the galaxy. These were all part of stars that existed well before our Sun and Earth and solar system were even formed.
The universe existed for billions of years before we did. And all of these elements that you see on the periodic table, you see carbon and oxygen and silicon and iron, the common elements throughout the universe, were all put there by previous generations of stars that either blew off winds like the Sun blows off a solar wind, or exploded in supernova explosions and thrust their elements throughout the universe.
These are the same things that we can trace with modern telescopes, like the Hubble Telescope and the James Webb Space Telescope, the Chandra X-ray Observatory. These are all elements that we can map out in the universe with these observatories and trace back to the same things that form us and the elemental abundances that we see in stars now are the same things that we see in the Earth’s crust, we see in asteroids. And so we know that these are the same elements that were once part of these stars.
So the question of, “How are we made of star stuff?”, in the words of Carl Sagan, “The cosmos is within us. We are made of star stuff. We are a way for the universe to know itself.”

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.”

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.

Wolk The Cygnus Loop, also known as the Veil Nebula, is a supernova remnant – the remains of the explosive death of a massive star. Studying images like these leads to discovery, but NASA’s Chandra X-ray Observatory provides another way to experience this data: three-dimensional (3D) models that allow people to explore – and print – examples of stars in the early and end stages of their lives.
The 3D model of the Cygnus Loop is the result of a simulation describing the interaction of a blast wave from the explosion with an isolated cloud of the interstellar medium (that is, dust and gas in between the stars). Chandra sees the blast wave and other material that has been heated to millions of degrees. These 3D models are based on state-of-the-art theoretical models, computational algorithms, and observations from space-based telescopes like Chandra that give us accurate pictures of these cosmic objects and how they evolve over time.

NASA’s Nancy Grace Roman Space Telescope team shared Thursday the designs for the three core surveys the mission will conduct after launch. These observation programs are designed to investigate some of the most profound mysteries in astrophysics while enabling expansive cosmic exploration that will revolutionize our understanding of the universe.
“Roman’s setting out to do wide, deep surveys of the universe in a way that will help us answer questions about how dark energy and dark matter govern cosmic evolution, and the demographics of worlds beyond our solar system,” said Gail Zasowski, an associate professor at the University of Utah and co-chair of the ROTAC (Roman Observations Time Allocation Committee). “But the overarching goal is that the surveys have broad appeal and numerous science applications. They were designed by and for the astronomical community to maximize the science they’ll enable.”
NASA’s Nancy Grace Roman Space Telescope’s three main observing programs, highlighted in this infographic, can enable astronomers to view the universe as never before, revealing billions of cosmic objects strewn across enormous swaths of space-time.Credit: NASA’s Goddard Space Flight Center Roman’s crisp, panoramic view of space and fast survey speeds provide the opportunity for astronomers to study the universe as never before. The Roman team asked the science community to detail the topics they’d like to study through each of Roman’s surveys and selected committees of scientists across many organizations to evaluate the range of possibilities and formulate three compelling options for each.
In April, the Roman team received the recommendations and has now determined the survey designs. These observations account for no more than 75 percent of Roman’s surveys during its five-year primary mission, with the remainder allocated to additional observations that will be proposed and developed by the science community in later opportunities.
“These survey designs are the culmination of two years of input from more than 1,000 scientists from over 350 institutions across the globe,” said Julie McEnery, Roman’s senior project scientist at NASA Goddard. “We’re thrilled that we’ve been able to hear from so many of the people who’ll use the data after launch to investigate everything from objects in our outer solar system, planets across our galaxy, dark matter and dark energy, to exploding stars, growing black holes, galaxies by the billions, and so much more.”
With all major hardware now delivered, Roman has entered its final phase of preparation for launch, undergoing integration and key environmental testing at NASA Goddard. Roman is targeted to launch by May 2027, with the team working toward a potential launch window that opens in October 2026.
This infographic describes the High-Latitude Wide-Area Survey that will be conducted by NASA’s Nancy Grace Roman Space Telescope. This observation program has three components, covering more than 5,000 square degrees (about 12 percent of the sky) altogether in just under a year and a half. The main part covers about 2,500 square degrees, doing both spectroscopy (splitting light into individual colors to study patterns that reveal detailed information) and imaging in multiple filters (which allow astronomers to select specific wavelengths of light) to provide the rich dataset needed for precise studies of our universe. A wider component spans more than twice the area using a single filter, specifically covering a large area that can be viewed by ground-based telescopes located in both the northern and southern hemispheres. The final component focuses on a smaller region to provide a deeper view that will help astronomers study faint, distant galaxies.Credit: NASA’s Goddard Space Flight Center High-Latitude Wide-Area Survey
Roman’s largest survey, the High-Latitude Wide-Area Survey, combines the powers of imaging and spectroscopy to unveil more than a billion galaxies strewn across a wide swath of cosmic time. Roman can look far from the dusty plane of our Milky Way galaxy (that’s what the “high-latitude” part of the survey name means), looking up and out of the galaxy rather than through it to get the clearest view of the distant cosmos.
The distribution and shapes of galaxies in Roman’s enormous, deep images can help us understand the nature of dark energy — a pressure that seems to be speeding up the universe’s expansion — and how invisible dark matter, which Roman will detect by its gravitational effects, influences the evolution of structure in our universe.
For the last two years, researchers have been discussing ways to expand the range of scientific topics that can be studied using the same dataset. That includes studying galaxy evolution, star formation, cosmic voids, the matter between galaxies, and much more.
This infographic describes the High-Latitude Time-Domain Survey that will be conducted by NASA’s Nancy Grace Roman Space Telescope. The survey’s main component covers over 18 square degrees — a region of sky as large as 90 full moons — and sees supernovae that occurred up to about 8 billion years ago. Smaller areas within the survey can pierce even farther, potentially back to when the universe was around a billion years old. The survey is split between the northern and southern hemispheres, located in regions of the sky that will be continuously visible to Roman. The bulk of the survey consists of 30-hour observations every five days for two years in the middle of Roman’s five-year primary mission.Credit: NASA’s Goddard Space Flight Center High-Latitude Time-Domain Survey
Roman’s High-Latitude Time-Domain Survey can probe our dynamic universe by observing the same region of the cosmos repeatedly. Stitching these observations together to create movies can allow scientists to study how celestial objects and phenomena change over time periods of days to years.
This survey can probe dark energy by finding and studying many thousands of a special type of exploding star called type Ia supernovae. These stellar cataclysms allow scientists to measure cosmic distances and trace the universe’s expansion.
“Staring at a large volume of the sky for so long will also reveal black holes being born as neutron stars merge, and tidal disruption events –– flares released by stars falling into black holes,” said Saurabh Jha, a professor at Rutgers University in New Brunswick, New Jersey, and ROTAC co-chair. “It will also allow astronomers to explore variable objects, like active galaxies and binary systems. And it enables more open-ended cosmic exploration than most other space telescopes can do, offering a chance to answer questions we haven’t yet thought to ask.”
This infographic describes the Galactic Bulge Time-Domain Survey that will be conducted by NASA’s Nancy Grace Roman Space Telescope. The smallest of Roman’s core surveys, this observation program consists of repeat visits to six fields covering 1.7 square degrees total. One field pierces the very center of the galaxy, and the others are nearby — all in a region of the sky that will be visible to Roman for two 72-day stretches each spring and fall. The survey mainly consists of six seasons (three early on, and three toward the end of Roman’s primary mission), during which Roman views each field every 12 minutes. Roman also views the six fields with less intensity at other times throughout the mission, allowing astronomers to detect microlensing events that can last for years, signaling the presence of isolated, stellar-mass black holes.Credit: NASA’s Goddard Space Flight Center Galactic Bulge Time-Domain Survey
Unlike the high-latitude surveys, Roman’s Galactic Bulge Time-Domain Survey will look inward to provide one of the deepest views ever of the heart of our Milky Way galaxy. Roman’s crisp resolution and infrared view can allow astronomers to watch hundreds of millions of stars in search of microlensing signals — gravitational boosts of a background star’s light that occur when an intervening object passes nearly in front of it. While astronomers have mainly discovered star-hugging worlds, Roman’s microlensing observations can find planets in the habitable zone of their star and farther out, including analogs of every planet in our solar system except Mercury.
The same set of observations can reveal “rogue” planets that drift through the galaxy unbound to any star, brown dwarfs (“failed stars” too lightweight to power themselves by fusion the way stars do), and stellar corpses like neutron stars and white dwarfs. And scientists could discover 100,000 new worlds by seeing stars periodically get dimmer as an orbiting planet passes in front of them, events called transits. Scientists can also study the stars themselves, detecting “starquakes” on a million giant stars, the result of sound waves reverberating through their interiors that can reveal information about their structures, ages, and other properties.
Data from all of Roman’s surveys will be made public as soon as it is processed, with no periods of exclusive access.
“Roman’s unprecedented data will offer practically limitless opportunities for astronomers to explore all kinds of cosmic topics,” McEnery said. “We stand to learn a tremendous amount of new information about the universe very rapidly after the mission launches.”
