NASA’s QuikScat satellite to be used to calibrate it’s successor RapidScat

NASA - National Aeronautics and Space AdministrationPasadena, CA – June 19th marked the 15th anniversary of the launch of NASA’s QuikScat, a satellite sent for a three-year mission in 1999 that continues collecting data. Built in less than 12 months, QuikScat has watched ocean wind patterns for 15 years and improved weather forecasting worldwide. Despite a partial instrument failure in 2009, it provides calibration data to international partners.

On this anniversary, the mission’s team is calibrating ISS-RapidScat, the successor that will maintain QuikScat’s unbroken data record. After its launch in a few months, RapidScat will watch ocean winds from the International Space Station (ISS) for a two-year mission.

Using data from NASA's QuikScat, weather forecasters were able to predict hazardous weather events over oceans 6 to 12 hours earlier than before these data were available. Orange areas show where winds are blowing the hardest and blue shows relatively light winds. (NASA)

NASA’s Groundbreaking Seastat Satellite marks 35th Anniversary

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – History tends to look fondly upon trailblazers, even if they don’t necessarily stick around. From musicians and actors to politicians and inventors, our lives are immeasurably enriched by the contributions of visionaries who left us.

So when NASA’s Jet Propulsion Laboratory, Pasadena, CA, launched an experimental satellite called Seasat to study Earth and its seas 35 years ago this week, only to see the mission end just 106 days later due to an unexpected malfunction, some at the time may have looked upon it as a failure.

NASA to send ISS-RapidScat instrument to International Space Station to measure Ocean Winds

NASA’s Jet Propulsion Laboratory

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.
