OREX (Orbital Re-entry Experiment) was a NASDA re-entry demonstrator prototype which was launched in 1994 on the H-II launcher; the satellite was renamed Ryūsei (りゅうせい, Shooting star). It was a precursor for the Japanese space shuttle HOPE.

OREX tested various communications systems, heating profiles and heat shielding components for HOPE.
