Status Update: HiWind Landed Friday, June 17!
HiWind - Flight 620N - LDB Relayed Real Time GPS Data: ** http://www.csbf.nasa.gov/map/balloon6/balloon6.htm **
- To measure summer time polar cap thermospheric neutral winds
- To study the ionosphere and thermosphere interaction in the polar cap during the summer
- To understand the Joule heating in the high latitude region which has a great impact on thermosphere global circulation
- To provide a better understanding of the energy transfer process from the solar wind to magnetosphere, ionosphere and thermosphere
- The observational results will have a great impact on space weather research and help to predict the ionosphere variation related to the thermosphere motion.
- HiWind is a balloon borne Fabry-Perot interferometer
- It will measure the thermospheric winds by monitoring the neutral wind induced Doppler shift in the airglow emission O 630 nm
- The O 630 nm emission is mostly from the thermosphere.
Scientific Payload Information:
- Weight 1600lb (not including CSBF components)
- Height 164 inch
- Sun pointing during the day and north pointing during the night
- HiWind payload status graphed data (not active until balloon is launched).
Ground Based Collaboration:
- HiWind is in flight over many ground based incoherent scatter radar sites
- Collaboration with ground based observation will be a key component for scientific research
- Ground based radars can provide ionosphere parameters, which can be combined with HiWind neutral wind data for ionosphere and thermosphere interaction study
- Arrangement with ground based PI has been made.
- HiWind payload completed an integration test at Ft. Sumner, New Mexico, in September 2010
- HiWind passed Mission Readiness Review in April 2011
- HiWind is launched and flying, June 14, 2011 from Kiruna, Sweden.
- HiWind Comes Down Friday, June 17, 2011!
- HiWind is the first balloon-borne FPI to measure the daytime thermospheric winds
- Thermospheric winds are critically needed for space weather research
- HiWind payload has modest pointing requirements and with a modest weight.
The project is supported by NASA grant NNX08AV35G from Geospace Science Program (part of Heliophysics Research program). For more information please contact principal investigator Qian Wu (email@example.com ).
