NASA - National Aeronautics and Space AdministrationPasadena, CA – In a clever reuse of hardware originally built to test parts of NASA’s QuikScat satellite, the agency will launch the ISS-RapidScat instrument to the International Space Station in 2014 to measure ocean surface wind speed and direction.

The ISS-RapidScat instrument will help improve weather forecasts, including hurricane monitoring, and understanding of how ocean-atmosphere interactions influence Earth’s climate.

NASA Study reveals degradation of Amazon Forest due to Climate Change

NASA - National Aeronautics and Space AdministrationPasadena, CA – An area of the Amazon rainforest twice the size of California continues to suffer from the effects of a megadrought that began in 2005, finds a new NASA-led study.

These results, together with observed recurrences of droughts every few years and associated damage to the forests in southern and western Amazonia in the past decade, suggest these rainforests may be showing the first signs of potential large-scale degradation due to climate change.

The megadrought in the Amazon rainforest during the summer of 2005 caused widespread damage and die-offs to trees, as depicted in this photo taken in Western Amazonia in Brazil. (Image credit: NASA/JPL-Caltech)

NASA’s Jet Propulsion Laboratory Scientists break the Ice on Icebergs

NASA - National Aeronautics and Space AdministrationPasadena, CA – Icebergs are a natural and beautiful part of Earth’s cryosphere, and are closely monitored and studied by scientists around the world.

We asked NASA’s Jet Propulsion Laboratory research scientists Ben Holt and Michael Schodlok to attempt to remove some of the mystery shrouding these floating flotillas of ice.
