Summary
Myojo & Ryusei launched on a Japan Aerospace Exploration Agency H-II from Yoshinobu Launch Complex LP-1, Tanegashima Space Center, Japan on February 3, 1994. It was Japan Aerospace Exploration Agency's 1st launch, 1st this year and humanity's 3,876th orbital launch attempt. It was the 1st H-II flight. The payload was bound for low Earth orbit (LEO). Ryusei, one of 3 catalogued objects, reached a 450 × 460 km orbit inclined 30.5°. 3 objects from this launch are catalogued, 2 of them payloads.

About this launch
The Vehicle Evaluation Payload (VEP), renamed Myojo after launch, was a Japanese spacecraft that provided a ranging function as well as functions to measure the acceleration and deformation, in order to confirm the accuracy of the H-2 rocket orbit injection and understand the environment of the payload equipment. The Orbital Re-entry Experiment (OREX), renamed Ryusei after launch contributed to HOPE development by accumulating experience in designing and producing a re-entry vehicle and acquiring re-entry data which is difficult to acquire in ground experiments.
