Quick Scatterometer

Mission Summary

The Quick Scatterometer, or QuikScat, is an Earth satellite designed to provide valuable data on ocean winds that revolutionized environmental predictions and weather forecasting. Designed as a speedy replacement for the Japan Aerospace Exploration Agency's Advanced Earth Observing Satellite-1 and its NASA Scatterometer instrument, QuikScat was conceived, developed and launched in less than two years. The satellite is part of NASA's Earth Observing System monitoring global climate change and was designed as a two-year mission, but spent 10 years in operation until it stopped collecting wind data in 2009 due to an age-related failure of a mechanism that spins the scatterometer antenna.

The data QuikScat collected has become such an intrinsic piece of weather predictions, including hurricane monitoring, that NASA has quickly begun preparations to launch a replacement instrument to the International Space Station in 2014. The new instrument, called ISS-RapidScat, was conceived with hardware originally built to test parts of QuikScat to allow the agency to cost-effectively and quickly put the replacement instrument in orbit.
