The Rocky Mountains in Colorado, as seen from the International Space Station. Snowmelt from the mountainous western United States is an essential natural resource, making up as much as 75% of some states’ annual freshwater supply. Summer heat has significant effects in the mountainous regions of the western United States. Melted snow washes from snowy peaks into the rivers, reservoirs, and streams that supply millions of Americans with freshwater—as much as 75% of the annual freshwater supply for some states.
But as climate change brings winter temperatures to new highs, these summer rushes of freshwater can sometimes slow to a trickle.
“The runoff supports cities most people wouldn’t expect,” explained Chris Derksen, a glaciologist and Research Scientist with Environment and Climate Change Canada. “Big cities like San Francisco and Los Angeles get water from snowmelt.”
To forecast snowmelt with greater accuracy, NASA’s Earth Science Technology Office (ESTO) and a team of researchers from the University of Massachusetts, Amherst, are developing SNOWWI, a dual-frequency synthetic aperture radar that could one day be the cornerstone of future missions dedicated to measuring snow mass on a global scale – something the science community lacks.
SNOWWI aims to fill this technology gap. In January and March 2024, the SNOWWI research team passed a key milestone, flying their prototype for the first time aboard a small, twin-engine aircraft in Grand Mesa, Colorado, and gathering useful data on the area’s winter snowfields.
“I’d say the big development is that we’ve gone from pieces of hardware in a lab to something that makes meaningful data,” explained Paul Siqueira, professor of engineering at the University of Massachusetts, Amherst, and principal investigator for SNOWWI.
SNOWWI stands for Snow Water-equivalent Wide Swath Interferometer and Scatterometer. The instrument probes snowpack with two Ku-band radar signals: a high-frequency signal that interacts with individual snow grains, and a low-frequency signal that passes through the snowpack to the ground.
The high-frequency signal gives researchers a clear look at the consistency of the snowpack, while the low-frequency signal helps researchers determine its total depth.
“Having two frequencies allows us to better separate the influence of the snow microstructure from the influence of the snow depth,” said Derksen, who participated in the Grand Mesa field campaign. “One frequency is good, two frequencies are better.”
The SNOWWI team in Grand Mesa, preparing to flight test their instrument. From an altitude of 4 kilometers (2.5 miles), SNOWWI can map 100 square kilometers (about 38 square miles) in just 30 minutes.
As both of those scattered signals interact with the snowpack and bounce back towards the instrument, they lose energy. SNOWWI measures that lost energy, and researchers later correlate those losses to features within the snowpack, especially its depth, density, and mass.
From an airborne platform with an altitude of 2.5 miles (4 kilometers), SNOWWI could map 40 square miles (100 square kilometers) of snowy terrain in just 30 minutes. From space, SNOWWI’s coverage would be even greater. Siqueira is working with Capella Space to develop a space-ready SNOWWI for satellite missions.
But there’s still much work to be done before SNOWWI visits space. Siqueira plans to lead another field campaign, this time in the mountains of Idaho. Grand Mesa is relatively flat, and Siqueira wants to see how well SNOWWI can measure snowpack tucked in the folds of complex, asymmetrical terrain.
For Derksen, who spends much of his time quantifying the freshwater content of snowpack in Canada, having a reliable database of global snowpack measurements would be game-changing.
“Snowmelt is money. It has intrinsic economic value,” he said. “If you want your salmon to run in mountain streams in the spring, you must have snowmelt. But unlike other natural resources, at this time, we really can’t monitor it very well.”

Since its launch in 2014, the Physical Sciences Informatics (PSI) system has served as NASA’s online repository for physical science data. Now, the PSI system is live with new updates to further align with NASA’s open data policy.
With its first significant update in over five years, the data repository has been completely redesigned, featuring a new layout, improved structure, and enhanced search functionalities. This updated system was created with a focus on user experience, and more updates are anticipated as new features are introduced.
A key new feature of the system is, the PSI Submission Portal. This tool is designed to streamline the processes of collecting, curating, and publishing new data by enabling Principal Investigators and scientific teams to upload files directly to the system with the support of a data curator. The Portal also offers a dedicated workspace for data submitters, assigns a unique digital object identifier to each dataset, and standardizes the documentation and data structure for each investigation.
Both the updated PSI system and Submission Portal can be accessed at PSI.NASA.gov.

NASA Science on Health, Safety to Launch on 31st SpaceX Resupply Mission
New science experiments for NASA are set to launch aboard the agency’s SpaceX 31st commercial resupply services mission to the International Space Station. The six investigations aim to contribute to cutting-edge discoveries by NASA scientists and research teams. The SpaceX Dragon spacecraft will liftoff aboard the company’s Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
Science experiments aboard the spacecraft include a test to study smothering fires in space, evaluating quantum communications, analyzing antibiotic-resistant bacteria, examining health issues like blood clots and inflammation in astronauts, as well as growing romaine lettuce and moss in microgravity.
Developing Firefighting Techniques in Microgravity
Putting out a fire in space requires a unique approach to prioritize the safety of the spacecraft environment and crew. The SoFIE-MIST (Solid Fuel Ignition and Extinction – Material Ignition and Suppression Test) is one of five investigations chosen by NASA since 2009 to develop techniques on how to contain and put out fires in microgravity. Research from the experiment could strengthen our understanding of the beginning stages of fire growth and behavior, which will assist in building and developing more resilient space establishments and creating better plans for fire suppression in space

Resistance to antibiotics is as much of a concern for astronauts in space as it is for humans on Earth. Research determined that the impacts of microgravity can weaken a human’s immune system during spaceflight, which can lead to an increase of infection and illness for those living on the space station.
The GEARS (Genomic Enumeration of Antibiotic Resistance in Space) investigation scans the orbiting outpost for bacteria resistant to antibiotics and these organisms are studied to learn how they thrive and adapt to microgravity. Research results could help increase the safety of astronauts on future missions as well as provide clues to improving human health on Earth.

Microgravity takes a toll on the human body and studies have shown that astronauts have had cases of inflammation and abnormally regulated blood clotting. The MeF-1 (Megakaryocytes Orbiting in Outer Space and Near Earth: The MOON Study (Megakaryocyte Flying-One)) investigation will conduct research on how the conditions in microgravity can impact the creation and function of platelets and bone-marrow megakaryocytes. Megakaryocytes, and their progeny, platelets, are key effector cells bridging the inflammatory, immune, and hemostatic continuum.
This experiment could help scientists learn about the concerns caused by any changes in the formation of clots, inflammation, and immune responses both on Earth and during spaceflight.

The work continues to grow food in the harsh environment of space that is both nutritious and safe for humans to consume. With Plant Habitat-07, research continues on ‘Outredgeous’ romaine lettuce, first grown on the International Space Station in 2014.
This experiment will sprout this red lettuce in microgravity in the space station’s Advanced Plant Habitat and study how optimal and suboptimal moisture conditions impact plant growth, nutrient content, and the plant microbiome. The knowledge gained will add to NASA’s history of growing vegetables in space and could also benefit agriculture on Earth.

ARTEMOSS (ANT1 Radiation Tolerance Experiment with Moss in Orbit on the Space Station) continues research that started on Earth with samples of Antarctic moss that underwent simulated solar radiation at the NASA Space Radiation Lab at Brookhaven National Lab in Upton, New York.
After exposure to radiation some of the moss samples will spend time on the orbiting outpost in the microgravity environment and some will remain on the ground in the 1g environment. ARTEMOSS will study how Antarctic moss recovers from any potential damage from ionizing radiation exposure when plants remain on the ground and when plants grow in spaceflight microgravity. This study leads the way in understanding the effects of combined simulated cosmic ionizing radiation and spaceflight microgravity on live plants, providing more clues to plant performance in exploration missions to come.

The SEAQUE (Space Entanglement and Annealing Quantum Experiment) will experiment with technologies that, if successful, will enable communication on a quantum level using entanglement. Researchers will focus on validating in space a new technology, enabling easier and more robust communication between two quantum systems across large distances. The research from this experiment could lead to developing building blocks for communicating between equipment such as quantum computers with enhanced security.
A quantum communications investigation, called SEAQUE (Space Entanglement and Annealing Quantum Experiment), is pictured as prepared for launch to the International Space Station on NASA’s SpaceX 31st commercial resupply services mission. The investigation is integrated on a MISSE-20 (Materials International Space Station Experiment) device, which is a platform for experiments on the outside of space station exposing instrumentation directly to the space environment. SEAQUE will conduct experiments in quantum entanglement while being exposed to the radiation environment of space Credit: NASA Related resources:

NASA’s work, including its Moon to Mars exploration approach, is advancing science and technology for the Artemis Generation, while also driving significant economic growth across the United States, the agency announced Thursday.
In its third agencywide economic impact report, NASA highlighted how its Moon to Mars activities, climate change research and technology development, and other projects generated more than $75.6 billion in economic output across all 50 states and Washington, D.C., in fiscal year 2023.
“To invest in NASA is to invest in American workers, American innovation, the American economy, and American economic competitiveness,” says NASA Administrator Bill Nelson. “Our work doesn’t just expand our understanding of the universe — it fuels economic growth, inspires future generations, and improves our quality of life. As we embark on the next great chapter of exploration, we are proud to help power economic strength, job creation, scientific progress, and American leadership on Earth, in the skies, and in the stars.”
Combined, NASA’s missions supported 304,803 jobs nationwide, and generated an estimated $9.5 billion in federal, state, and local taxes throughout the United States.
The study found NASA’s Moon to Mars activities generated more than $23.8 billion in total economic output and supported an estimated 96,479 jobs nationwide. For investments in climate research and technology, the agency’s activities generated more than $7.9 billion in total economic output and supported an estimated 32,900 jobs in the U.S.
Additional key findings of the study include:
Every state in the country benefits economically through NASA activities. Forty-five states have an economic impact of more than $10 million. Of those 45 states, eight have an economic impact of $1 billion or more. The agency’s Moon to Mars initiative, which includes the Artemis missions, generated nearly $2.9 billion in tax revenue. These activities provided about 32% of NASA’s economic impact. The agency’s investments in climate change research and technology generated more than $1 billion in tax revenue. Approximately 11% of NASA’s economic impacts are attributable to its investments in climate change research and technology. NASA had more than 644 active international agreements for various scientific research and technology development activities in the 2023 fiscal year. The International Space Station, representing 15 countries and five space agencies, has a predominant role in the agency’s international partnerships. In fiscal year 2023, NASA oversaw 2,628 active domestic and international non-procurement partnership agreements, which included 629 new domestic and 109 new international agreements, active partnerships with 587 different non-federal partners across the U.S., and partnerships in 47 of 50 states. NASA Spinoffs, which are public products and processes that are developed with NASA technology, funding, or expertise, provide a benefit to American lives beyond dollars and jobs. As of result of NASA missions, our fiscal year 2023 tech transfer activities produced 1,564 new technology reports, 40 new patent applications, 69 patents issued, and established 5,277 software usage agreements. Scientific research and development, which fuels advancements in science and technology that can help improve daily life on Earth and for humanity, is the largest single-sector benefitting from NASA’s work, accounting for 19% of NASA’s total economic impact. The study was conducted by the Nathalie P. Voorhees Center for Neighborhood and Community Improvement at the University of Illinois at Chicago.
