Summary
ASNARO-2 launched on a Japan Aerospace Exploration Agency Epsilon from Mu Center, Uchinoura Space Center, Japan on January 17, 2018. It was Japan Aerospace Exploration Agency's 30th launch, 1st this year and humanity's 5,713th orbital launch attempt. It was the 3rd Epsilon flight and the 1st this year. The payload was bound for Sun-Synchronous Orbit (SSO). ASNARO-2, one of 3 catalogued objects, reached a 500 × 513 km orbit inclined 97.4°. 3 objects from this launch are catalogued, one of them a payload.
