Image 1 - Bromine Explosions Being Driven By Climate Change
2012-03-03 05:42:44

According to a new study, Arctic sea ice reductions may be intensifying the chemical release of bromine into the atmosphere, causing ground-level ozone depletion and the deposit of mercury in the Arctic. A team of scientists combined data from six NASA, European Space Agency and Canadian Space Agency satellites to develop a model of how air moves in the atmosphere to link Arctic sea ice changes to bromine explosions over the Beaufort Sea. "Shrinking summer sea ice has drawn much...

Image 1 - NASA Pinning Down 'Here' Better Than Ever
2012-02-25 05:16:20

Before our Global Positioning System (GPS) navigation devices can tell us where we are, the satellites that make up the GPS need to know exactly where they are. For that, they rely on a network of sites that serve as "you are here" signs planted throughout the world. The catch is, the sites don't sit still because they're on a planet that isn't at rest, yet modern measurements require more and more accuracy in pinpointing where "here" is. To meet this need, NASA is helping to lead an...

Image 1 - Titan Is A Moon Of Many Moods

A set of recent papers, many of which draw on data from NASA's Cassini spacecraft, reveal new details in the emerging picture of how Saturn's moon Titan shifts with the seasons and even throughout the day. The papers, published in the journal Planetary and Space Science in a special issue titled "Titan through Time", show how this largest moon of Saturn is a cousin - though a very peculiar cousin - of Earth. "As a whole, these papers give us some new pieces in the jigsaw puzzle that is...

Image 1 - NASA Map Sees Earth's Trees In A New Light
2012-02-20 09:30:41

A NASA-led science team has created an accurate, high-resolution map of the height of Earth's forests. The map will help scientists better understand the role forests play in climate change and how their heights influence wildlife habitats within them, while also helping them quantify the carbon stored in Earth's vegetation. Scientists from NASA's Jet Propulsion Laboratory, Pasadena, Calif.; the University of Maryland, College Park; and Woods Hole Research Center, Falmouth, Mass., created...

NASA has selected 33 small satellites to fly as auxiliary payloads aboard rockets planned to launch in 2013 and 2014. The proposed CubeSats come from universities across the country, the Radio Amateur Satellite Corporation, NASA field centers and Department of Defense organizations. CubeSats are a class of research spacecraft called nanosatellites. The cube-shaped satellites are approximately four inches long, have a volume of about one quart and weigh less than three pounds. The...

Galaxy Evolution Explorer Goes Into Standby Mode
2012-02-09 04:48:55

NASA's Galaxy Evolution Explorer, or Galex, was placed in standby mode today as engineers prepare to end mission operations, nearly nine years after the telescope's launch. The spacecraft is scheduled to be decommissioned -- taken out of service -- later this year. The mission extensively mapped large portions of the sky with sharp ultraviolet vision, cataloguing millions of galaxies spanning 10 billion years of cosmic time. The Galaxy Evolution Explorer launched into space from a Pegasus...

Juno Spacecraft Refines Path To Jupiter
2012-02-06 09:58:11

NASA's solar-powered Juno spacecraft successfully refined its flight path last Wednesday with the mission's first trajectory correction maneuver. The maneuver took place on Feb. 1. It is the first of a dozen planned rocket firings that, over the next five years, will keep Juno on course for its rendezvous with Jupiter. "We had a maneuver planned soon after launch but our Atlas V rocket gave us such a good ride we didn't need to make any trajectory changes," said Rick Nybakken, Juno project...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
