Most farm fields in the U.S. Midwest lay bare over the winter. From the time of corn and soybean harvests—sometime between September and December—until the planting season in spring, valuable topsoil is often unprotected. Wind, snowmelt, and rain can remove topsoil and nutrients from fields and carry them into the Mississippi River, where, instead of ...

LORIS, a shoebox-sized nanosatellite designed and built by students in the Dalhousie Space Systems Lab over the past several years, was finally released last Thursday (Dec. 29) by NASA after its ascent to the International Space Station late last fall. The student team, led by Engineering Masters student Arad Gharagozli, created the satellite as part ...

Just four days after heavy rain hit California, the state was drenched with another atmospheric river on January 4 and 5, 2023. A plume of moisture from the tropical Pacific interacted with a low-pressure system that rapidly strengthened over the northeast Pacific, producing a storm that caused flooding, toppled trees, and downed power lines. This ...

Un simulador de incendios forestales diseñado en Zaragoza por un grupo de jóvenes ingenieros e informáticos, se ha convertido en finalista en un concurso de ideas convocado por la NASA. Con esta aplicación han conseguido ser uno de los 35 equipos de todo el mundo que han llegado a la final del ‘NASA Space Apps ...

NASA has selected Space Exploration Technologies (SpaceX) to provide launch services for the Sentinel-6B mission. Sentinel-6B will continue the long-term global sea level data record begun in 1992 by Topex/Poseidon, followed by Jason 1, 2, 3, and Sentinel-6 Michael Freilich. The mission is a partnership between NASA, the National Oceanic and Atmospheric Administration, the European ...

On Earth, “we have GPS, and it’s easy to take advantage of that and not think about all the technology that goes into it,” says Alvin Yew, a research engineer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “But now when we’re on the moon, we just don’t have that.” Inspired by previous research ...

NASA is working to reestablish contact with one of the eight spacecraft that make up its Cyclone Global Navigation Satellite System (CYGNSS) constellation, which monitors hurricanes. CYGNSS is the first space-based system to collect frequent measurements of wind speeds from the ocean’s surface near the eye of storms such as tropical cyclones, typhoons and hurricanes. ...

El Servicio Nacional de Meteorología e Hidrología del Perú (Senamhi) anunció el lanzamiento de Senamhi GEOGloWS, una plataforma que cuenta con tecnología de la Administración Nacional de Aeronáutica y del Espacio (NASA). Con los datos obtenidos se espera optimizar el pronóstico de inundaciones a nivel nacional. Este nuevo sistema ha sido personalizado con las condiciones ...

From Lake Pontchartrain to the Texas border, Louisiana has lost enough wetlands since the mid-1950s to cover the entire state of Rhode Island. Using a first-of-its kind model, NASA-funded researchers quantified those wetlands losses at nearly 21 square miles (54 square kilometers) per year since the early 1980s. In the new study, scientists used the ...

Since mid-September 2022, NASA-funded instruments have been hitching rides on commercial aircraft and collecting environmental data over New Zealand. The collaboration with Air New Zealand is the first known data-collecting partnership between a passenger airline and a NASA Earth science mission. The new program is part of NASA’s Cyclone Global Navigation Satellite System (CYGNSS) mission, ...

A team of researchers from GERS including Zhu and NRE Ph.D. student Tian Li, along with researchers from NASA and the University of Maryland Earth System Science Interdisciplinary Center has developed a method that is capable of providing daily global moderate resolution nighttime light change maps. The results are published in the journal Remote Sensing ...

For decades, satellite images have clearly captured how rampant deforestation is destroying the Amazon rainforest. But what about the trees that remain standing? What do their dimensions tell us about our planet’s future? Quite a lot, in fact. Since 2018, a first-of-its-kind mission by NASA has deployed lasers mounted aboard the International Space Station to ...

NASA and the U.S. Geological Survey (USGS) will map portions of the southwest United States for critical minerals using advanced airborne imaging. Hyperspectral data from hundreds of wavelengths of reflected light can provide new information about Earth’s surface and atmosphere to help scientists understand Earth’s geology and biology, as well as the effects of climate ...

Instituto Federal do Ceará (IFCE), Nasa, Agência Espacial Brasileira (AEB), Universidade Federal Rural do Semi-árido (Ufersa-RN) e Universidade Mackenzie firmaram acordo para realizar experimentos e projetos conjuntos em nível de pesquisa, desenvolvimento e inovação (PD&I), e em pós-graduação. As ações serão voltadas ao estudo da geodésia do planeta Terra, modelagens do campo gravitacional, radioastronomia, além ...

Using older models and newer methods, Hu and the team of scientists conclude that ants and photons are extremely alike in the realm of snow-depth research. This helped the principle come to fruition that light bouncing around in snow would produce gaugable and viable results. ICESat-2 (Ice, Cloud, and Land Elevation Satellite-2) now reads light ...

Purdue University professor Bryan Pijanowski’s research team will be working in some wild and remote places around the globe in the coming year. Pijanowski’s sound-source surveyors will be equipped with microphones, headphones and parabolic reflectors to efficiently collect sound waves from the natural world. Their tools also include low-flying drones and sensors mounted on orbiting ...

Monitoring vegetation shifts in the Arctic can help scientists understand how the area is changing as the world warms. Already, researchers have documented expansion of boreal forests into the tundra. And at many sites in the region, the tundra is greening up, according to recent satellite observations. NASA postdoctoral fellow Andy Maguire says these vegetation ...

NASA transferred ownership and operational control on Thursday of the Landsat 9 satellite to the U.S. Geological Survey (USGS) in a ceremony in Sioux Falls, South Dakota. Landsat 9 is the most recent in the Landsat series of remote-sensing satellites, which provide global coverage of landscape changes on Earth. The Landsat program – a joint ...

Water is life, but for all its importance, humanity has a surprisingly limited view of Earth’s freshwater bodies. Researchers have reliable water level measurements for only a few thousand lakes around the world, and little to no data on some of the planet’s important river systems. The upcoming Surface Water and Ocean Topography (SWOT) satellite ...

An interdisciplinary team of researchers, led by University of Minnesota Twin Cities data scientists and supported by the U.S. National Science Foundation and NASA, has published a first-of-its-kind comprehensive global dataset of the lakes and reservoirs on Earth showing how they have changed over the last 30+ years. The data will provide environmental researchers with ...

“ESA’s Lunar Pathfinder mission will help verify the performance of new lunar navigation techniques in development at NASA,” said JJ Miller, Deputy Director of Policy and Strategic Communications for NASA’s Space Communications and Navigation (SCaN) program at NASA Headquarters in Washington. “This project is built on the long collaboration between NASA and ESA within the ...
