AIRS: 15 years of seeing what’s in the air

04 May 2017

Accurate weather forecasts save lives. NASA's Atmospheric Infrared Sounder (AIRS) instrument, launched on this date 15 years ago on NASA's Aqua satellite, significantly increased weather forecasting accuracy within a couple of years by providing extraordinary three-dimensional maps of clouds, air temperature and water vapor throughout the atmosphere's weather-making layer. Fifteen years later, AIRS continues to be a valuable asset for forecasters worldwide, sending 7 billion observations streaming into forecasting centers every day.

Celebrating 17 years of NASA’s ‘Little Earth satellite that could’

30 March 2017

The satellite was little (the size of a small refrigerator), only supposed to last one year and constructed and operated on a shoestring budget — yet it persevered. After 17 years of operation, with more than 1,500 research papers generated and more than 92,000 images captured from each of its imagers, the Earth Observing-1 (EO-1) satellite has exceeded expectations in its technology, research goals and longevity.
