More than 400 miles above Earth, a satellite the size of a school bus is earning its frequent flyer miles. On Oct. 6, NASA’s Terra completed 100,000 orbits around Earth. Terra, which launched Dec. 18, 1999, is projected to continue operation into the 2020s.

For the first time ever, measurements from NASA Earth-observing research satellites are being used to help combat a potential outbreak of life-threatening cholera. Humanitarian teams in Yemen are targeting areas identified by a NASA-supported project that precisely forecasts high-risk regions based on environmental conditions observed from space.

Does Dust Affect Water Levels of the Caspian Sea

June 10, 2016

Dust storms over the Caspian Sea lead to increased evaporation and a drop in lake level according to new research using observations of dust collected by instruments on several satellites including the Moderate Imaging Spectroradiometer (MODIS ) and the Multi-angle Imaging Spectroradiometer (MISR) on Terra.

A Satellite Eye on Mount Ruapehu

June 5, 2010

Mount Ruapehu is one of New Zealand’s most active volcanoes and most visited, dotted with skiers and snowboarders along its slopes.  When it erupts lahars, flows of volcanic debris and sediment, can have devastating impacts, prompting geologists to regularly monitor the volcano, using the Advanced Spaceborne Thermal Emission and Reflection Radiometer on NASA’s Terra satellite.

The Rains of Roanu

May 24, 2016 

Tropical Storm Roanu made landfall in Bangladesh, unleashing heavy winds and rain on the country’s populous coastal communities. On May 21, 2016, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color image of the storm. Roanu progressed northeast over the Bay of Bengal before making landfall in Bangladesh.

Early Breakup of the Beaufort Sea Ice 

May 20, 2016 

The Beaufort Sea ice pack starts to thin and break up in spring when temperatures begin to rise, usually in late May. However, much of the Beaufort Sea’s ice had already broken by mid-April. Images from the Moderate Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured the progression in April in 2014, 2015, and 2016.
