Permafrost zones occupy nearly a quarter of the exposed land area of the Northern Hemisphere. NASA’s Carbon in Arctic Reservoirs Vulnerability Experiment is probing deep into the frozen lands above the Arctic Circle in Alaska to measure emissions of the greenh... More »
This illustration shows the path of the small asteroid 2013 LR6, which will safely pass within 65,000 miles (105,000 kilometers) of Earth on June 7 at 9:42 p.m. PDT (June 8 at 12:42 a.m. EDT). Image credit: NASA/JPL-Caltech. Small asteroid 2013 LR6 will safely... More »
Researchers for the first time mapped the extent and frequency of understory fires across a study area (green) spanning 1.2 million square miles (3 million square kilometers) in the southern Amazon forest. Fires were widespread across the forest frontier durin... More »
Small asteroid 2013 LR6 will safely fly past this evening at 9:42 p.m. PDT (which is June 8 at 12:42 a.m. EDT/June 8 at 04:42 UTC) at a distance of about 65,000 miles (105,000 kilometers) above Earth’s surface. The space rock, which is about 30 feet (10 meters... More »
Opportunity’s view of ‘Solander Point’ NASA’s Mars Exploration Rover Opportunity used its panoramic camera (Pancam) to acquire this view of “Solander Point” during the mission’s 3,325th Martian day, or sol (June 1, 2013). Image credit: NASA/JPL-Caltech/Cornell... More »
This image of asteroid 1998 QE2 was obtained on June 1, 2013, when the asteroid was about 3.75 million miles (6 million kilometers) from Earth. The small white dot at lower right is the moon, or satellite, orbiting asteroid 1998 QE2. Image credit: NASA/JPL-Cal... More »
NASA’s DC-8 flying laboratory will carry a team of scientists and their sensors for the Studies of Emissions, Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) campaign. SEAC4RS will investigate how pollution and natural emissi... More »
