Summary
Kakehashi launched on a Japan Aerospace Exploration Agency H-II from Yoshinobu Launch Complex LP-1, Tanegashima Space Center, Japan on February 21, 1998. It was Japan Aerospace Exploration Agency's 6th launch, 1st this year and humanity's 4,219th orbital launch attempt. It was the 6th H-II flight and the 1st this year. The payload was bound for Geostationary Orbit (Direct-GEO). Kakehashi, one of 2 catalogued objects, reached a 256 × 1,882 km orbit inclined 30.1°. 2 objects from this launch are catalogued, one of them a payload.
