"It was a successful flight," wrote principal investigator Dr. Paul Kitner, in his daily CAPER update. "We wish to thank all of the many dedicated and talented individuals who contributed to the CAPER project." Just after the launch Prof. Kitner and his colleagues toasted the success of the mission with champagne before heading to the airport for their return to the United States.

"The success of the CAPER mission could significantly advance our understanding of Earth's magnetosphere and of space weather," says Mr. Mark Adrian, a plasma physicist at the University of Alabama, Huntsville who helped build two of CAPER's instruments. "Yesterday, the sounding rocket flew through the so-called 'Cleft Ion Fountain' which is a major contributor to charged particles in the magnetosphere. There's a debate going on now among plasma physicists about the source of energy that drives the fountain's particle flow. No one is quite certain where the free energy comes from, but there are some good ideas. The data from CAPER should clearly distinguish between competing models and help us understand how the ion fountain really works."
CAPER was funded by NASA and launched in collaboration with the Norwegian Space Agency, Andoya Rocket Range, UNIS. The GSFC/Wallop Flight Facility project manager was Dave Moltedo.

CAPER Team: Dr. Paul Kintner of Cornell University is CAPER's principal investigator, and oversees the instruments that are provided by several other institutions. The NASA/Marshall science team was led by Dr. Michael Chandler and includes Ms. Victoria Coffey of NASA/Marshall and Mr. Mark Adrian of the University of Alabama in Huntsville. Coffey and Adrian were responsible for the front-end electrostatic analyzers and calibration for the electron, TECHS, and ion, TICHS, measuring instruments. Dr. Craig Pollock of Southwest Research Institute was the lead for the TECHS and TICHS instrument team, which includes Dr. Thomas Moore of NASA/Goddard.
The CAPER payload pictured left was integrated at the Andoya Rocket Range in Andoya, Norway. It blasted off yesterday atop a three-stage Black Brant XII sounding rocket like the one that launched SCIFER (right) in 1995. (Pictures from Andoya Rocket Range)
Solar wind blows some of Earth's atmosphere into space. Dec. 8, 1998. Polar spacecraft measures "auroral fountain" flowing out as solar wind flows in.
