Validating Carbon Dioxide Measurements from NASA's OCO-2 Over Los Angeles
This image shows NASA's OCO-2 measurements of carbon dioxide levels over Pasadena and the northern Los Angeles basin on Sept. 5, 2014. Each colored dot represents a single measurement of the greenhouse gas made during an overflight of the area.
Iceland's Bardarbunga Volcano Imaged by NASA Spacecraft
Since the end of August 2014, Iceland's Bardarbunga volcano has been pouring out lava from a growing fissure. NASA's Terra spacecraft shows the flows have been accompanied by spectacular lava fountains.
Tanzania Images Highlight Improvements in Full-Resolution SRTM Africa Data
A site in the Crater Highlands of Tanzania reveals the difference between NASA's Shuttle Radar Topography Mission (SRTM) digital elevation model data as originally released in 2004 (left) and as now released at full resolution in 2014 (right).
Progress of Hawaii Lava Flow Tracked by NASA Spacecraft
On June 27, 2014, a new vent opened on Hawaii's Puu Oo vent, on the eastern flank of Kilauea volcano. NASA's Terra spacecraft shows the hot lava flow in white, extending about 11 miles (17 kilometers) from the vent.

Progress of Icelandic Lava Flows Charted by NASA's EO-1 Spacecraft
On the night of Sept. 6, 2014 NASA's Earth Observing 1 (EO-1) spacecraft observed the ongoing eruption at Holuhraun, Iceland. Partially covered by clouds, this scene shows the extent of the lava flows that have been erupting.
NASA's E-DECIDER Rapid Disaster Decision Support Products
A NASA-funded disaster decision support system, provided a number of rapid response map data products to decision makers at the California Earthquake Clearinghouse following its activation for the Aug. 24, 2014 magnitude 6.0 earthquake in Napa, California
On the night of Sept. 1, 2014, NASA's Earth Observing 1 (EO-1) spacecraft observed the ongoing eruption at Holuhraun, Iceland. This false-color image that emphasizes the hottest areas of the vent and resulting lava flows.
2013 Yosemite Fire Assessed by NASA Satellite Data
In this image from NASA's Aqua satellite, the red areas seen by the MODIS instrument revealed that live fuel moisture had excessively dried up by more than 50 percent prior to the Rim Fire in August 2013.
The Surrogate robot ('Surge'), built at NASA's Jet Propulsion Laboratory in Pasadena, CA., is being developed in order to extend humanity's reach into hazardous environments to perform tasks such as using environmental test equipment.
This image from NASA's Terra spacecraft shows the world's largest bauxite mine found near Weipa, Queensland, Australia. The rich aluminum deposits were first recognized on the end of the Cape York Peninsula in 1955, and mining began in 1960.
