Energy Servers Deliver Clean, Affordable Power

Imagine you are about to be dropped in the middle of a remote, inhospitable region—say the Kalahari Desert. What would you want to have with you on your journey back to civilization? Food and water, of course, but you can only carry so much. A truck would help, but

Compact Radiometers Expand Climate Knowledge

NASA not only peers up to gather information about space; it also peers down to gather information about Earth. As part of the Science Mission Directorate, NASA’s Earth Science Program aims to improve predictions about climate, weather, and natural hazards by understanding Earth’s response to natural and human-induced changes. One

Systems Analyze Water Quality in Real Time

If you are planning a day at your local park or even a weekend camping trip, you would simply pack all the food, drink, and supplies you need. Similarly, astronauts on short-term space missions can get away with packing the provisions they need to survive in space. But long-term space

World Wind Tools Reveal Environmental Change

NASA Technology “Who has more satellite data than NASA?” asks Patrick Hogan. The question is a rhetorical one. After dozens of Earth-observing satellite launches and missions to other planets, NASA has accumulated an unmatched amount of planetary science information, including satellite imagery, terrain information, and climate data. To visualize this data and make it accessible, in 2002 Hogan and

Analyzers Measure Greenhouse Gasses, Airborne Pollutants

NASA Technology In complete darkness, a NASA observatory waits. When an eruption of boiling water billows from a nearby crack in the ground, the observatory’s sensors seek particles in the fluid, measure shifts in carbon isotopes, and analyze samples for biological signatures. NASA has landed the observatory in this remote location, far removed from air and sunlight,

Remediation Technologies Eliminate Contaminants

NASA Technology All research and development has a story behind it, says Jacqueline Quinn, environmental engineer at Kennedy Space Center. For Quinn, one such story begins with the Saturn 1B launch stand at Kennedy and ends with a unique solution to a challenging environmental problem.

Receivers Gather Data for Climate, Weather Prediction

NASA Technology Signals from global positioning system (GPS) satellites are now being used for more than just location and navigation information. By looking at the radio waves from GPS satellites, a technology developed at NASA’s Jet Propulsion Laboratory (JPL) not only precisely calculates its position, but can also use a technique known as radio occultation to help

Coating Processes Boost Performance of Solar Cells

NASA Technology NASA currently has spacecraft orbiting Mercury (MESSENGER), imaging the asteroid Vesta (Dawn), roaming the red plains of Mars (the Opportunity rover), and providing a laboratory for humans to advance scientific research in space (the International Space Station, or ISS). The heart of the technology that powers those missions and many others can be held in the

Analyzers Provide Water Security in Space and on Earth

NASA Technology Resourcefulness is a key quality for living in space, and on the International Space Station (ISS), that means making the most of water supplies. In 2008, the installation of the Water Processing Assembly (WPA) onboard the ISS allowed the space station’s crew to do just that. The WPA purifies moisture from nearly every possible source—sweat,

Catalyst Substrates Remove Contaminants, Produce Fuel

NASA Technology “A spacecraft is the ultimate tight building. We don’t want any leaks, and there is very little fresh air coming in,” says Jay Perry, an aerospace engineer at Marshall Space Flight Center. “As a result, there is a huge potential for a buildup of contaminants from a host of sources.”
