One of the key elements of Earth’s climate system is the cryosphere – the many forms of ice found on Earth. Two new NASA missions use different technologies to help scientists better understand how frozen water is affecting our planet. Both will continue satellite data records that have greatly...

The Sun. It inspires songs, warms us, and grows our food. Life on land and in the oceans, the daily weather, and long-term climate patterns happen primarily because of energy we receive from our closest star. Even tiny variations in that energy can affect the workings of our planet’s atmosphere.... Read More

Oceans cover over 70% percent of Earth’s surface and profoundly influence our planet’s atmosphere, weather, and climate. However, uncovering the many secrets hidden beneath the ocean’s waves presents unique challenges for researchers, and requires specific technology to observe what humans can’t... Read More

Imagine standing on the roof of a building in Los Angeles and trying to point a laser so accurately that you could hit a particular building in San Diego, more than 100 miles (160 kilometers) away. This accuracy is required for the feat that a novel technology demonstration aboard the soon-to-... Read More

West Nile Virus (WNV) is commonly spread to humans by the bites of Culex sp. mosquitoes. As South Dakota is the U.S. hotspot for WNV, local scientists and public health officials developed a way to use environmental data from NASA satellites to forecast disease risk. These data help inform... Read More

Large accumulations of cyanobacteria (blue-green algae) are toxic and harmful to people and animals. NASA Aqua and Terra satellite data help detect, forecast, and target responses to Harmful Algal Blooms in the Great Lakes and Florida. This information can aid in risk assessment and decision making... Read More

River blindness (onchocerciasis) is an affliction caused by a parasitic worm that is transmitted person-to-person by the bites of Simulium sp. black flies. The Carter Center targeted its river blindness eradication efforts in the Americas by using Landsat and Terra satellite data to find previously... Read More

Ozone (O3) in the air we breathe can have detrimental effects on human health and the environment. The U.S. EPA utilized NASA Aura satellite data of North American background ozone levels to guide its updated National Ambient Air Quality Standards. These new standards will enhance public health for... Read More

It can happen in a flash — airborne science, that is. Two hundred microseconds, to be exact. With lasers shot from the belly of a King Air B200 aircraft. That’s right, scientists are shooting lasers at atmospheric gases — not to zap them out of existence, but to measure them.
