NASA Inaugurates New Space Station Era as Earth Science Observation Platform with RapidScat Instrument

NASA inaugurated a new era of research for the International Space Station (ISS) as an Earth observation platform following the successful installation and activation of the ISS-RapidScat science instrument on the outposts exterior at Europes Columbus module.

The ISS Rapid Scatterometer, or ISS-RapidScat, is NASAs first research payload aimed at conducting near global Earth science from the stations exterior and will be augmented with others in coming years.

RapidScat is designed to monitor ocean winds for climate research, weather predictions, and hurricane monitoring.

The 1280 pound (580 kilogram) experimental instrument is already collecting its first science data following its recent power-on and activation at the station.

Its antenna began spinning and it started transmitting and receiving its first winds data on Oct.1, according to a NASA statement.

The first image from RapidScat was released by NASA on Oct. 6, shown below, and depicts preliminary measurements of global ocean near-surface wind speeds and directions.

The $26 million remote sensing instrument uses radar pulses to observe the speed and direction of winds over the ocean for the improvement of weather forecasting.

Most satellite missions require weeks or even months to produce data of the quality that we seem to be getting from the first few days of RapidScat, said RapidScat Project Scientist Ernesto Rodriguez of NASAs Jet Propulsion Laboratory, Pasadena, California, which built and manages the mission.
