LRE (Laser Reflecting Equipment) is a Japanese test spacecraft that was launched from the Tsukuba Space Center in the Tanegashima island by a H-2A rocket at 07:29 UT on 29 August 2001. The main goal was to launch the H-2A successfully after its earlier version, H-2 had failed sequentially. The H-2A is a modified version with (unlike the H-2) many components procured in the international markets. The 87 kg LRE is a passive mirror ball of diameter 51 cm and carries 24 glass sheets and 126 prisms on its surface, and was ejected from the H-2A just to ascertain the rocket's potential capability for precisely launching four tonne payloads with the help of light echoes from the LRE. Though the eventual goal of H-2A is to launch geosynchronous spacecraft with capabilities comparable to some of the rockets in other countries, but at a lower cost, the LRV will remain merely in a "transfer orbit".
