If you asked someone what they expected to see during a visit to NASA’s Johnson Space Center, they would probably list things like astronauts, engineers, and maybe a spacecraft or two. It might be a surprise to learn you can also spy hundreds of species of animals – from geckos and snakes to white-tailed deer and red-tailed hawks.
Ensuring those species and Johnson’s workforce can safely coexist is the main job of Matt Strausser, Johnson’s senior biologist for wildlife management. Strausser works to reduce the negative impacts animals can have on Johnson’s operations as well as the negative impact humans might have on native wildlife and their habitats.
NASA’s Johnson Space Center Senior Biologist Matt Strausser leads a nature hike to Johnson staff that detailed the native plant species and wildlife onsite, invasive species, and mitigation efforts.NASA/Lauren Harnett Strausser joined NASA in 2012, fresh out of graduate school, when he was hired on a six-month contract to write Johnson’s first Wildlife Management Plan. “My contract was extended a couple of times until I became a regular part of the facilities service contract, which is where I still am today,” he said.
Strausser remembers being interested in natural resources from a young age. “I spent a lot of my childhood poring through copies of National Geographic, hiking, and camping,” he said. When it was time for college, Strausser decided to study biology and natural resource management. He spent his summers in jobs or internships that mostly involved endangered wildlife species, including Attwater’s prairie chickens, which are bred at Johnson through a partnership with the Houston Zoo. Strausser noted that he conducted research across the country while he was a student, and even studied fish for a short time in the South Pacific.
“After all of those adventures in faraway places, I find it ironic that I ended up about 20 miles from where I grew up,” he said. “Once I got onsite, it did not take me long to find that this property has great remnant native plant communities, a fascinating land use history, and some unique natural resource challenges that come from the work done here. Those factors really drew me in and helped motivate me to build a career at Johnson.”
Matthew Strausser received a Silver Snoopy Award through NASA’s Space Flight Awareness Program in 2018, in recognition of his efforts to prevent and mitigate ant-inflicted damage to critical infrastructure electrical systems. From left: NASA astronaut Reid Weissman, Strausser, Strausser’s wife Kayla, NASA Acting Associate Administrator Vanessa Wyche. NASA Strausser’s work involves a variety of activities. First, he gathers data about Johnson’s wildlife populations and their habitats. “I use population counts, conflict records, satellite and aerial imagery, nest surveys, outside reports, and even historical data to get an understanding of what’s on the landscape and what problems we have to tackle,” he said.
With that information, Strausser works to engage project and facility managers and provide recommendations on how to prevent or reduce the impact of wildlife problems onsite. Strausser works with Johnson’s facilities maintenance group to modify buildings to keep animals on the outside, and he gets support from the Johnson veterinarian on animal health issues. He also works closely with Johnson’s pest control and groundskeeping contracts, as their work is often adjacent to wildlife management.
He supports the safety team, as well. “Our security contractors are a great resource for reporting wildlife issues as well as helping address them,” Strausser said, adding that some of Johnson’s safety groups “have been really helpful at getting the word out about how to stay safe around our wildlife” in coordination with the center’s internal communications team. His team also responds to wildlife conflict calls, which often involve capturing and relocating animals that have wandered into areas where they pose a risk to people or operations.
Additionally, Strausser runs the facilities contract’s small unmanned aircraft system, which uses drones to conduct facility inspections, support hurricane response, and survey on-site wildlife.

NASA The nature of his work has instilled in Strausser an appreciation for teamwork and collaboration among colleagues with distinct experiences. Each of the projects he works on involves team members from different organizations and contracts, and most of them do not have a background in biology. “Building a wildlife and natural resource program from the ground up and bringing all of these once-disconnected and diverse professionals together to effectively address problems – that is the achievement I take the most pride in,” he said.
Strausser observed that accomplishing the goals of the agency’s Artemis campaign will require a tremendous amount of specialized support infrastructure, and that developing and running that infrastructure will require a wide variety of professionals. “It is going to require students and specialists with all different types of backgrounds, passions, and talents.”
Overall, Strausser said he has a very dynamic job. “Wildlife issues tend to be very seasonal, so throughout the year, the types of issues I am addressing change,” he said. “On top of that, there are always new projects, problems, and questions out there that keep the work fresh and challenging.” He has learned the value of being open to new challenges and learning new skills. “Being adaptable can be just as important as mastery in a specific field,” he said.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Information provided by the NASA-ISRO Synthetic Aperture Radar mission (NISAR) will help to protect and inform communities around the world. The data will aid in managing agricultural fields, monitoring volcanoes, and tracking land-based ice including glaciers.NASA/JPL-Caltech Data from NISAR will map changes to Earth’s surface, helping improve crop management, natural hazard monitoring, and tracking of sea ice and glaciers.
A new U.S.-India satellite called NISAR (NASA-ISRO Synthetic Aperture Radar) will provide high-resolution data enabling scientists to comprehensively monitor the planet’s land and ice surfaces like never before, building a detailed record of how they shift over time. Hailed as a critical part of a pioneering year for U.S.-India civil space cooperation by President Trump and Prime Minister Modi during their visit in Washington in February, the NISAR launch will advance U.S.-India cooperation and benefit the U.S. in the areas of disaster response and agriculture.
As the first joint satellite mission between NASA and the Indian Space Research Organisation (ISRO), NISAR marks a new chapter in the growing collaboration between the two space agencies. Years in the making, the launch of NISAR builds on a strong heritage of successful programs, including Chandrayaan-1 and the recent Axiom Mission 4, which saw ISRO and NASA astronauts living and working together aboard the International Space Station for the first time.
The information NISAR provides will help decision-makers, communities, and scientists monitor agricultural fields, refine understanding of natural hazards such as landslides and earthquakes, and help teams prepare for and respond to disasters like hurricanes, floods, and volcanic eruptions. The satellite will also provide key global observations of changes to ice sheets, glaciers, and permafrost, as well as forests and wetlands.
The NISAR mission is slated to launch no earlier than July 30 from Satish Dhawan Space Centre on India’s southeastern coast aboard an ISRO Geosynchronous Satellite Launch Vehicle.
Here are five things to know about NISAR:
1. The NISAR satellite will provide a 3D view of Earth’s land and ice.
Two synthetic aperture radars (SARs) aboard NISAR will detect changes in the planet’s surface down to fractions of an inch. The spacecraft will bounce microwave signals off Earth’s surface and receive the return signals on a radar antenna reflector measuring 39 feet (12 meters) across. The satellite’s ability to “see” through clouds and light rain, day and night, will enable data users to continuously monitor earthquake- and landslide-prone areas and determine how quickly glaciers and ice sheets are changing. It also will offer unprecedented coverage of Antarctica, information that will help with studying how the continent’s ice sheet changes over time.
2. Data from NISAR will provide critical insights to help governments and decision-makers plan for natural and human-caused hazards.
Earthquakes, volcanoes, and aging infrastructure can pose risks to lives and property. Able to see subtle changes in Earth’s surface, NISAR can help with hazard-monitoring efforts and potentially give decision-makers more time to prepare for a possible disaster. For earthquakes, NISAR will provide insights into which parts of a fault slowly move without producing quakes and which are locked together and could potentially slip. The satellite will be able to monitor the area around thousands of volcanoes, detecting land movement that could be a precursor to an eruption. When it comes to infrastructure such as levees, aqueducts, and dams, NISAR data collected over time can help managers detect if nearby land motion could jeopardize key structures, and then assess the integrity of those facilities.
3. The most advanced radar system ever launched as part of a NASA or ISRO mission, NISAR will generate more data on a daily basis than any previous Earth satellite from either agency.
About the length of a pickup truck, NISAR’s main body contains a dual-radar payload — an L-band system with a 10-inch (25-centimeter) wavelength and an S-band system with a 4-inch (10-centimeter) wavelength. Each system is sensitive to land and ice features of different sizes and specializes in detecting certain attributes, such as moisture content, surface roughness, and motion. By including both radars on one spacecraft — a first — NISAR will be more capable than previous SAR missions. These two radars, one from NASA and one from ISRO, and the data they will produce, exemplify how collaboration between spacefaring allies can achieve more than either would alone.
NISAR press kit The radars will generate about 80 terabytes of data products per day over the course of NISAR’s prime mission. That’s roughly enough data to fill about 150 512-gigabyte hard drives each day. The information will be processed, stored, and distributed via the cloud — and accessible to all.
This artist’s concept depicts the NISAR satellite in orbit over central and Northern California. The spacecraft will survey all of Earth’s land and ice-covered surfaces twice every 12 days.NASA/JPL-Caltech 4. The NISAR mission will help monitor ecosystems around the world.
The mission’s two radars will monitor Earth’s land and ice-covered surfaces twice every 12 days. Their near-comprehensive coverage will include areas not previously covered by other Earth-observing radar satellites with such frequency. The NISAR satellite’s L-band radar penetrates deep into forest canopies, providing insights into forest structure, while the S-band radar is ideal for monitoring crops. The NISAR data will help researchers assess how forests, wetlands, agricultural areas, and permafrost change over time.
5. The NISAR mission marks the first collaboration between NASA and ISRO on a project of this scale and marks the next step in a long line of Earth-observing SAR missions.
The NISAR satellite features components developed on opposite sides of the planet by engineers from ISRO and NASA’s Jet Propulsion Laboratory working together. The S-band radar was built at ISRO’s Space Applications Centre in Ahmedabad, while JPL built the L-band radar in Southern California. After engineers from JPL and ISRO integrated NISAR’s instruments with a modified ISRO I3K spacecraft bus and tested the satellite, ISRO transported NISAR to Satish Dhawan Space Centre in May 2025 to prepare it for launch.
The SAR technique was invented in the U.S. in 1952 and now countries around the globe have SAR satellites for a variety of missions. NASA first used the technique with a space-based satellite in 1978 on the ocean-observing Seasat, which included the first spaceborne SAR instrument for scientific observations. In 2012, ISRO began launching SAR missions starting with Radar Imaging Satellite (RISAT-1), followed by RISAT-1A in 2022, to support a wide range of applications in India.

NASA’s James Webb Space Telescope has taken the most detailed image of planetary nebula NGC 1514 to date thanks to its unique mid-infrared observations. Webb shows its rings as intricate clumps of dust. It’s also easier to see holes punched through the bright pink central region.NASA, ESA, CSA, STScI, Michael Ressler (NASA-JPL), Dave Jones (IAC) In this photo released on April 14, 2025, NASA’s James Webb Space Telescope revealed the gas and dust ejected by a dying star at the heart of NGC 1514. Using mid-infrared data showed the “fuzzy” clumps arranged in tangled patterns, and a network of clearer holes close to the central stars shows where faster material punched through.
This scene has been forming for at least 4,000 years — and will continue to change over many more millennia. At the center are two stars that appear as one in Webb’s observation, and are set off with brilliant diffraction spikes. The stars follow a tight, elongated nine-year orbit and are draped in an arc of dust represented in orange.
One of these stars, which used to be several times more massive than our Sun, took the lead role in producing this scene. “As it evolved, it puffed up, throwing off layers of gas and dust in in a very slow, dense stellar wind,” said David Jones, a senior scientist at the Institute of Astrophysics on the Canary Islands, who proved there is a binary star system at the center in 2017.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Sunlight gleams off NASA’s Lunar Trailblazer as the dishwasher-size spacecraft orbits the Moon in this artist’s concept. The mission will discover where the Moon’s water is, what form it is in, and how it changes over time, producing the best-yet maps of water on the lunar surface.Lockheed Martin Space The small satellite mission will map the Moon to help scientists better understand where its water is, what form it’s in, how much is there, and how it changes over time.
Launching no earlier than Wednesday, Feb. 26, NASA’s Lunar Trailblazer will help resolve an enduring mystery: Where is the Moon’s water? After sharing a ride on a SpaceX Falcon 9 rocket with Intuitive Machines’ IM-2 launch — part of NASA’s CLPS (Commercial Lunar Payload Services) initiative — the small satellite will take several months to arrive in lunar orbit.
Here are six things to know about the mission.
1. Lunar Trailblazer will produce high-resolution maps of water on the lunar surface.
One of the biggest lunar discoveries in recent decades is that the Moon’s surface has quantities of water, but little about its nature is known. To investigate, Lunar Trailblazer will decipher where the water is, what form it is in, how much is there, and how it changes over time. The small satellite will produce the best-yet maps of water on the lunar surface. Observations gathered during the two-year prime mission will also contribute to the understanding of water cycles on airless bodies throughout the solar system.
2. The small satellite will use two state-of-the-art science instruments.
Key to achieving these goals are the spacecraft’s two science instruments: the High-resolution Volatiles and Minerals Moon Mapper (HVM3) infrared spectrometer and the Lunar Thermal Mapper (LTM) infrared multispectral imager. NASA’s Jet Propulsion Laboratory in Southern California provided the HVM3 instrument, while LTM was built by the University of Oxford and funded by the UK Space Agency.
HVM3 will detect and map the spectral fingerprints, or wavelengths of reflected sunlight, of minerals and the different forms of water on the lunar surface. The LTM instrument will map the minerals and thermal properties of the same landscape. Together they will create a picture of the abundance, location, and form of water while also tracking how its distribution changes over time and temperature.
Fueled and attached to an adaptor used for secondary payloads, NASA’s Lunar Trailblazer is seen at SpaceX’s payload processing facility within NASA’s Kennedy Space Center in Florida in early February 2025. The small satellite is riding along on Intuitive Machines’ IM-2 launch.SpaceX 3. Lunar Trailblazer will take a long and winding road to the Moon.
Weighing only 440 pounds (200 kilograms) and measuring 11.5 feet (3.5 meters) wide with its solar panels fully deployed, Lunar Trailblazer is about the size of a dishwasher and relies on a relatively small propulsion system. To make the spacecraft’s four-to-seven-month trip to the Moon (depending on the launch date) as efficient as possible, the mission’s design and navigation team has planned a looping trajectory that will use the gravity of the Sun, Earth, and Moon to guide Lunar Trailblazer to its final science orbit — a technique called low-energy transfer.
4. The spacecraft will peer into the darkest parts of the Moon’s South Pole.
Lunar Trailblazer’s science orbit positions it to peer into the craters at the Moon’s South Pole using the HVM3 instrument. What makes these craters so intriguing is that they harbor cold traps that may not have seen direct sunlight for billions of years, which means they’re a potential hideout for frozen water. The HVM3 spectrometer is designed to use faint reflected light from the walls of craters to see the floor of even permanently shadowed regions. If Lunar Trailblazer finds significant quantities of ice at the base of the craters, those locations could be pinpointed as a resource for future lunar explorers.
5. Lunar Trailblazer is a high-risk, low-cost mission.
Lunar Trailblazer was a 2019 selection of NASA’s SIMPLEx (Small Innovative Missions for Planetary Exploration), which provides opportunities for low-cost science spacecraft to ride-share with selected primary missions. To maintain a lower overall cost, SIMPLEx missions have a higher risk posture and lighter requirements for oversight and management. This higher risk acceptance allows NASA to enable science missions that could not otherwise be done.
6. Future missions will benefit from Lunar Trailblazer’s data.
Mapping the Moon’s water supports future human and robotic lunar missions. With knowledge from Lunar Trailblazer of where water is located, astronauts could process lunar ice to create water for human use, breathable oxygen, or fuel. And they could conduct science by sampling the ice for later study to determine the water’s origins.
More About Lunar Trailblazer
Lunar Trailblazer is led by Principal Investigator Bethany Ehlmann of Caltech in Pasadena, California. Caltech also leads the mission’s science investigation, and Caltech’s IPAC leads mission operations, which includes planning, scheduling, and sequencing of all spacecraft activities. NASA JPL manages Lunar Trailblazer and provides system engineering, mission assurance, the HVM3 instrument, and mission design and navigation. JPL is managed by Caltech for NASA. Lockheed Martin Space provided the spacecraft, integrated the flight system, and supports operations under contract with Caltech. The University of Oxford developed and provided the LTM instrument, funded by the UK Space Agency. Lunar Trailblazer, part of NASA’s Lunar Discovery Exploration Program, is managed by NASA’s Planetary Mission Program Office at Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington.
