Orbital Re-entry Experiment Vehicle (named "RYUSEI", which means "shooting star", after inserted to orbit) was launched by the first flight of H-II rocket at 7:20 a m. on the 4th of February in 1994, and inserted into about 450km circular orbit in 14 minutes after lift off. After passed around the earth, "RYUSEI" fired de-orbit burn normally, In about 2 hours 1 minute after lift off, an airplane telemetry station, a ship station and Christmas ground station begun to receive the electric waves from "RYUSEl", which was re-entering into atmosphere. Communication blackout, peculiar to atmospheric re-entry, were observed in these stations from 2 hours 3 minutes to 5 minutes after lift off. The experimental data during this period were transmitted to the stations after the blackout. " RYUSEl" splashed down in the expected area of the Central Pacific Ocean in 2 hours 13 minutes after lift off. This paper reports on summary of OREX flight profile, points to be considered in making OREX flight plan, and flight results.
