NASA's AIRS Instrument Tracks Transport of Sulfur Dioxide from Chilean Volcanic Eruption (Animation)
This frame from a movie shows alternating day and nighttime views of the plume of sulfur dioxide gas emitted by Calbuco, as observed by NASA's AIRS instrument onbpard NASA's Aqua spacecraft, from April 22 to May 4, 2015.
SMAP's Radiometer Captures Views of Global Soil Moisture
These maps of global soil moisture were created using data from the radiometer instrument on NASA's Soil Moisture Active Passive (SMAP) observatory. Evident are regions of increased soil moisture and flooding during April, 2015.
NASA/Caltech Team Images Nepal Quake Fault Rupture, Surface Movements
Using a combination of GPS-measured ground motion data, satellite radar data, and seismic observations, scientists have constructed preliminary estimates of how much April 25, 2015, magnitude 7.8 Gorkha earthquake in Nepal moved below Earth's surface.
NASA's ARIA Project Provides New Look at Earth Surface Deformation from Nepal Quake
This false-color map shows the amount of permanent surface movement caused almost entirely by the 7.8 Gorkha earthquake in Nepal during a 70-day interval between two ALOS-2 images, acquired February 21 and May 2, 2015.
Ground Deformation from Chilean Volcanic Eruption Shown by Satellite Radar Image
This satellite interferometric synthetic aperture radar image-pair shows relative deformation of the Earth's surface when nn April 22-23, 2015, significant explosive eruptions occurred at Calbuco volcano, Chile.
The April 18, 2015 eruption of Calbuco Volcano in Chile, as seen by NASA's Terra spacecraft, led to the evacuation of thousands of citizens near the summit, blanketed nearby towns with a layer of ash, and disrupted air traffic.
This simulated image shows how a cloud of glitter in geostationary orbit would be illuminated and controlled by two laser beams. As the cloud orbits Earth, grains scatter the sun's light at different angles like many tiny prisms.
NASA RapidScat Proving Valuable for Tropical Cyclones
On Jan. 28, 2015 from 2:41 to 4:14 UTC, NASA's ISS-RapidScat saw the nor'easter's strongest sustained winds (red) between 56 and 67 mph (25 to 30 mps/90 to 108 kph) just off-shore from eastern Cape Cod.
NASA Soil Moisture Mission Produces First Global Radiometer Map
With its antenna now spinning at full speed, NASA's new Soil Moisture Active Passive (SMAP) observatory has successfully re-tested its science instruments and generated its first global maps, a key step to beginning routine science operations in May, 2015
