Summary
Polar launched on an United States Air Force Delta II 7925-10 from Space Launch Complex 2W, Vandenberg SFB, CA, USA on February 24, 1996. It was United States Air Force's 961st launch, 3rd this year and humanity's 4,055th orbital launch attempt. It was the 2nd Delta II 7925-10 flight and the 1st this year. The payload was bound for Elliptical Orbit (Elliptical). Polar, one of 3 catalogued objects, reached a 193 × 50,558 km orbit inclined 86.0°. 3 objects from this launch are catalogued, one of them a payload.

About this launch
Polar is one of four spacecraft in the Global Geospace Science (GGS) program. These are among the spacecraft (Wind, Geotail, SOHO, and Cluster) in the International Solar Terrestrial Physics (ISTP) program. POLAR measures solar wind entry, ionospheric output, and the depositions of energy into the neutral atmosphere at high latitudes.
