Summary
Kiku-1 launched on a National Space Development Agency of Japan N-I from Osaki Launch Complex, Tanegashima Space Center, Japan on September 9, 1975. It was National Space Development Agency of Japan's 1st launch, 1st this year and humanity's 1,737th orbital launch attempt. It was the 1st N-I flight. The payload was bound for low Earth orbit (LEO). The tracked orbit of Kiku-1, one of 2 catalogued objects, from October 3, 1975, was 983 × 1,111 km inclined 47.0°. 2 objects from this launch are catalogued, one of them a payload.
