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...

NASA's NuSTAR Ships To Vandenberg For March 14 Launch
2012-01-26 06:41:18

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, shipped to Vandenberg Air Force Base, Calif., on Tuesday, to be mated to its Pegasus launch vehicle. The observatory will detect X-rays from objects ranging from our sun to giant black holes billions of light-years away. It is scheduled to launch March 14 from an aircraft operating out of Kwajalein Atoll in the Marshall Islands. "The NuSTAR mission is unique because it will be the first NASA mission to focus X-rays in the high-energy...

Image 1 - Models Reveal That Vesta Is Likely Cold And Dark Enough For Ice
2012-01-26 05:40:12

Though generally thought to be quite dry, roughly half of the giant asteroid Vesta is expected to be so cold and to receive so little sunlight that water ice could have survived there for billions of years, according to the first published models of Vesta's average global temperatures and illumination by the sun. "Near the north and south poles, the conditions appear to be favorable for water ice to exist beneath the surface," says Timothy Stubbs of NASA's Goddard Space Flight Center in...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
