Reimei

Reimei ('Dawn') is the in-flight name for a small Japanese satellite known during development as INDEX (INnovative-technology Demonstration Experiment), developed in-house at JAXA both to serve as a demonstration of small-satellite technologies (particularly high-performance and high-accuracy attitude control) and to perform simultaneous optical and charged-particle observation of the aurora. A notable feature is the 25 µm-thick polyimide mirrors used for concentrating sunlight onto the solar arrays.

It is 72 cm × 62 cm × 62 cm and weighs 72 kilograms. The construction budget was $4 million. The satellite was launched into a near-sun-synchronous 630 km orbit on 24 August 2005 as a piggyback on the OICETS launch.^[1]^[2]
