Sink Hole Swallows Car In Chevy Chase, Maryland
2014-03-07 05:05:08

redOrbit Staff & Wire Reports – Your Universe Online For well over a year now, sinkholes have been in the news, as the geological features have been responsible for incidents such as the February 2013 death of a Florida man whose entire bedroom was swallowed up by one and the more recent damaging of eight historic automobiles at the National Corvette Museum in Kentucky. Now, NASA has revealed a new analysis of airborne radar data collected in 2012 which shows that the instruments...

WASHINGTON, March 6, 2014 /PRNewswire-USNewswire/ -- New analyses of NASA airborne radar data collected in 2012 reveal the radar detected indications of a huge sinkhole before it collapsed and forced evacuations near Bayou Corne, La. that year. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The findings suggest such radar data, if collected routinely from airborne systems or satellites, could at least in some cases foresee sinkholes before they happen, decreasing danger to...

NASA Completes Icelandic Glacier Winter Movement Radar Study
2014-02-10 08:26:13

Beth Hagenauer - NASA The cold of an Icelandic winter did not stop one NASA science aircraft from completing a mission to map glaciers on the island during the past week. NASA's C-20A, based at the Dryden Aircraft Operations Facility in Palmdale, Calif., flew four radar missions from Keflavik International Airport near Reykjavik, Iceland. The aircraft carries a precision NASA synthetic aperture radar, developed by the Jet Propulsion Laboratory in Pasadena, Calif., that uses a...

Mapping Forest Biomass To Understand The Global Carbon Cycle
2013-02-05 10:54:59

ESA Satellite radar data are being used to map Earth´s vital resources. The latest advances and applications of the POLinSAR remote sensing technique were highlighted at a conference held last week. Polarimetric InSAR — or POLinSAR — is a remote sensing technique based on polarimetric information in Synthetic Aperture Radar (SAR) images. With this technique, a radar sends polarised pulses towards the target, and the information in the signals backscattered from Earth...

Volcanic Eruptions Predicted With Satellite Imagery
2012-11-05 14:28:53

Brett Smith for redOrbit.com - Your Universe Online In a new report published in the journal Geophysical Research Letters, two scientists showed they may now be able to detect signs of an impending volcanic eruption by analyzing satellite imagery. Using Interferometric Synthetic Aperture Radar (InSAR) over the active volcanoes in Indonesia's west Sunda arc, the vulcanologists from University of Miami uncovered evidence that showed the ℠inflation´ of several volcanoes prior to...


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.'
