Astronomers used the Galaxy Evolution Explorer (GALEX) telescope to take this deep image in ultraviolet light of the sprawling spiral galaxy M81, hoping to learn where it kept its hot stars. Hot stars emit more ultraviolet than cool stars, and are frequently associated with young, open clusters of stars and energetic star-forming regions. Less than […]

HMA’s fire-suppression technology is ideal for a host of firefighting applications, including combating wildfires in areas unreachable by standard fire trucks. Here, HMA’s L3 (light, lean, and lethal) vehicle demonstrates these capabilities.
Space-Propulsion Technology Helps Suppress Fires Faster

By Bo Schwerin   Much deserved attention is given to the feats of innovation that allow humans to live in space and robotic explorers to beam never-before-seen images back to Earth.

The Aquarius instrument is integrated to the service platform at INVAP (Bariloche) just before its shipment to Brazil for environmental testing.
An Argentine Partnership with NASA

By Matthew Kohut   When the Aquarius mission launched from Vandenberg Air Force Base in June 2011, few Americans outside the Earth-science and space communities probably knew that the satellite itself came from Argentina.

This global map shows temperature anomalies for July 4–11, 2010, compared with temperatures for the same dates from 2000 to 2008. CLARREO’s ability to measure trends over a decade or more could help scientists know whether climate change will be less or more severe than expected as much as two decades earlier than current data allow.
CLARREO: Bringing Disciplines Together

By David Young   CLARREO, the Climate Absolute Radiance and Refractivity Observatory, is an Earth-science satellite mission in pre-Phase A (conceptual study) that is being designed to capture critical climate-change data much more precisely than has been possible with existing instruments.

Artist’s concept of the SOHO spacecraft exploring the center of the sun. In reality, the spacecraft does this indirectly, by analyzing ripples on the solar surface that come from the deep interior.
The Million-Mile Rescue

By the NASA Safety Center   The Solar Heliospheric Observatory (SOHO) is a major element of the joint International Solar Terrestrial Program between NASA and the European Space Agency (ESA).
