Research and Application News
![]() Last spring, NASA researchers flew over the Everglades and Puerto Rico to measure how mangroves and rainforests grow and evolve over time. Five months later, hurricanes Irma and Maria tore through those study areas – creating a unique opportunity to investigate the devastating effects of massive storms on these ecosystems, as well as their gradual recovery. ![]() How heavy oxygen ions escape Earth’s gravity05 April 2018A new study reveals that low-frequency electromagnetic waves accompany intense heating events at low altitudes. ![]() Antarctica loses grip03 April 2018ESA's CryoSat mission has revealed that, over the last seven years, Antarctica has lost an area of underwater ice the size of Greater London. This is because warm ocean water beneath the continent's floating margins is eating away at the ice attached to the seabed. ![]() Sentinels helping to map minerals20 March 2018The traditional way of mapping Earth's geology and mineral resources is a costly and time-consuming undertaking. While satellites cannot entirely replace the expert in the field, they can certainly help – as a recent effort in Africa shows. ![]() Getting to know Steve16 March 2018Steve – a strange shimmering ribbon of purple light in the night sky – was discovered in 2016, but now, thanks to ESA's Swarm mission, more is known about this weird feature of the aurora. ![]() Weather satellites aid search and rescue capabilities07 March 2018NOAA's Geostationary Operational Environmental Satellite (GOES) constellation monitors Earth's environment, helping meteorologists observe and predict the weather. ![]() Clouds play a prominent role in moderating Earth's climate, but their role is still poorly understood. Generally, clouds cool the Earth by reflecting incoming sunlight back out into space. Reducing the cloud's reflectivity - with a layer of pollution, for example - reduces the cooling effect. New research suggests that smoke from fires may be counteracting this effect by making clouds more reflective. ![]() The United States filled a crucial gap in its weather-forecasting arsenal when it launched its latest geostationary satellite on 01 March. The craft will enable meteorologists to track hurricanes, snow storms and other threats as they develop. It will also beam down data that researchers can use to measure air temperature and humidity — if they can work out how to incorporate them into their models. ![]() World's fishing fleets mapped from orbit23 February 2018It's another demonstration of the power of Big Data - of mining a huge batch of statistics to see patterns of behaviour that were simply not apparent before. ![]() New study brings Antarctic ice loss into sharper focus20 February 2018A NASA study based on an innovative technique for crunching torrents of satellite data provides the clearest picture yet of changes in Antarctic ice flow into the ocean. The findings confirm accelerating ice losses from the West Antarctic Ice Sheet and reveal surprisingly steady rates of flow from its much larger neighbour to the east. ![]() Land use change has warmed the Earth's surface20 February 2018Recent changes to vegetation cover are causing the Earth's surface to heat up. Activities like cutting down evergreen forests for agricultural expansion in the tropics create energy imbalances that lead to higher local surface temperatures and contribute to global warming. ![]() Multipurpose mapping16 February 2018NOAA-based team makes 3-D coastal models for underwater navigation, emergency management, science exhibits, and more. |
