Two NASA California centers have been selected to develop new space-aged technologies that could be game-changers in the way we look at planets from above and how we safely transport robots or humans through space and bring them safely back to Earth.

NASA’s Jet Propulsion Laboratory in Pasadena, Calif., will use advanced compound semiconductor materials to develop new technologies for the High Operating Temperature Infrared Sensor Demonstration. The higher the temperature at which an infrared detector can operate, the less power is required to cool it. Reduced power needs can translate into operational cost and system weight savings. If successful, this sensor technology could be used in many future NASA Earth and planetary science instruments, as well as for U.S. commercial and defense applications. (more…)

PASADENA, Calif. – A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere.

The study, published online Sunday, Oct. 2, in the journal Nature, finds the amount of ozone destroyed in the Arctic in 2011 was comparable to that seen in some years in the Antarctic, where an ozone “hole” has formed each spring since the mid-1980s. The stratospheric ozone layer, extending from about 10 to 20 miles (15 to 35 kilometers) above the surface, protects life on Earth from the sun’s harmful ultraviolet rays. (more…)
