Light, Tough, Inexpensive Climate Sensors
Miniature Sandia Sensors May Advance Climate Studies
Apr 10, 2012 12:44 PM E
An air sampler the size of an ear plug is expected to cheaply and easily collect atmospheric samples to improve computer climate models. "We now have an inexpensive tool for collecting pristine vapor samples in the field," said Sandia National Laboratories researcher Ron Manginell, lead author of the cover story for the Review of Scien...

12-Mile-High Martian Dust Devil Caught in Act
Apr 09, 2012 12:44 PM E
A Martian dust devil roughly 12 miles high (20 kilometers) was captured whirling its way along the Amazonis Planitia region of Northern Mars on March 14. It was imaged by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. Despite its height, the plume is little more than three-quarters of a fo...

Astronaut Vision Changes Offer Opportunity for More Research
Apr 07, 2012 13:47 PM E
Astronauts on the International Space Station are not allowing vision issues to keep them from completing their important tasks on the orbiting laboratory. In fact, they are taking advantage of the opportunity to study why weightlessness alters vision.

Dust Storm in the Taklimakan Desert
Apr 07, 2012 11:03 AM E
Dust storms continued in the Taklimakan Desert in western China through early April 2012. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this natural-color image on April 5. Dust was thickest along the desert's southern margin.

NASA's TRMM Satellite Sees Tornadic Texas Storms in 3-D
Apr 07, 2012 08:07 AM E
NASA's Tropical Rainfall Measuring Mission (TRMM) satellite provides a look at thunderstorms in three dimensions and shows scientists the heights of the thunderclouds and the rainfall rates coming from them, both of which indicate severity.

NRL Scientists Identify New Coupling Mode Between Stratosphere and Ionosphere
Apr 06, 2012 06:37 AM E
Scientists at the Naval Research Laboratory have identified a new mode of coupling between the stratosphere - which can drive variations at the summer mesopause - and the ionosphere, thereby establishing a new means where changes in the stratosphere can impact space weather. This research appeared in the January 6th, 2012 issue of Geophysical Research Letters.

Dark Heart of a Cosmic Collision
Apr 05, 2012 12:52 PM E
Infrared and X-ray observations from two space telescopes have been combined to create a unique look at violent events within the giant galaxy Centaurus A. The observations strengthen the view that the galaxy may have been created by the cataclysmic collision of two older galaxies.
GOES Satellite Movie Tracked Tornadic Texas Trouble
Apr 05, 2012 10:46 AM E
A powerful weather system moved through eastern Texas and dropped at least 15 tornadoes in the Dallas suburbs. NASA created an animation of data from NOAA's GOES-13 satellite that shows the frontal system moving through the region yesterday.

Space Station Keeps Watch on World's Sea Traffic
Apr 04, 2012 08:30 AM E
As the International Space Station circles Earth, it has been tracking individual ships crossing the seas beneath. An investigation hosted by the European Space Agency (ESA) in its Columbus module has been testing the viability of monitoring global maritime traffic from the station's orbit hundreds of miles (kilometers) above since June 2010.

NASA Infrared Image Sees a Stronger Tropical Storm Daphne
Apr 04, 2012 06:44 AM E
Tropical Storm Daphne strengthened overnight and was captured in an infrared image from NASA's Terra satellite. Daphne moved away from the Fiji islands and remains north of New Zealand in the South Pacific on April 3, 2012.
