GLOBE-Trotting Science Lands in Chesapeake with NASA eClipsOn June 16-17, 2025, 50 students at Camp Young in Chesapeake, Virginia traded their usual summer routines for microscopes. The NASA eClips team from the National Institute of Aerospace Center for Integrative STEM Education (NIA-CISE) taught two engaging lessons focused on macroinvertebrates and plankton, with a surprising star of the show – mosquitoes!
Camp Young, a Title I camp program serving students from Norfolk Public Schools, provides year-round, environmental science-based learning. The NASA eClips’ visit reinforced their mission to help students explore their environment on the Elizabeth River while seeing its place in the Earth System.
The lessons, designed for students in grades 3 through 8, were inspired by NASA’s GLOBE (Global Learning and Observations to Benefit the Environment) program, which encourages people around the world to collect and share environmental data as ‘citizen scientists’. This is where mosquitos stole the show! The lesson focuses on how these tiny insects can serve as indicators of climate and habitat change. By identifying mosquito larvae and understanding their breeding environments, students contributed to the bigger picture of global health and environmental monitoring, right from their own backyard.
During this experience, Camp Young’s stunning waterfront on the Elizabeth River was turned into a living laboratory. With phytoplankton nets, petri dishes, and sample jars in hand, campers ventured into the field to collect real environmental data, bringing their findings back to a cabin-turned-classroom to analyze them with scientific tools, including microscopes provided by the NASA eClips team.
Rather than just reading about ecosystems and the kinds of scientific questions that arise within them, students got to experience them firsthand and experience real science in the field. “It’s one thing to talk about microscopic marine organisms,” one instructor noted, “but it’s another thing entirely when students can actually see them swimming in a droplet from the river.”
The NASA eClips project provides educators with standards-based videos, activities, and lessons to increase STEM literacy through the lens of NASA. It is supported by NASA under cooperative agreement award number NNX16AB91A and is part of NASA’s Science Activation Portfolio.

The Day Earth Smiled
On July 19, 2013, NASA’s Cassini spacecraft had a rare opportunity to image Saturn and, far in the background, Earth. This image spans about 404,880 miles (651,591 kilometers) across.
With the Sun’s powerful and potentially damaging rays eclipsed by Saturn itself, Cassini’s onboard cameras were able to take advantage of this unique viewing geometry. They acquired a panoramic mosaic of the Saturn system that allows scientists to see details in the rings and throughout the system as they are backlit by the sun. This mosaic is special as it marks the third time our home planet was imaged from the outer solar system; the second time it was imaged by Cassini from Saturn’s orbit; and the first time ever that inhabitants of Earth were made aware in advance that their photo would be taken from such a great distance.
Before the mission ended in 2017, Cassini was already a powerful influence on future exploration. Lessons learned during Cassini’s mission are being applied in NASA’s Europa Clipper mission. The mission uses an orbital tour design derived from the way Cassini explored Saturn. Launched in 2024, Europa Clipper will reach Jupiter in April 2030 and make dozens of flybys of the planet’s icy moon to determine whether there are places below the surface that could support life.

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 kitThe 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.

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.
