マーズ・エクスプレス
Mars Express was a two-part mission consisting of the Mars Express Orbiter and Beagle 2 lander launched in June 2003. While the lander portion of the mission failed, the orbiter is still in use. The Mars Express Orbiter consists of three instruments with the purpose of analyzing the surface and subsurface of Mars: the High Resolution Stereo Camera (HRSC), Observatoire pour la Minéralogie, l'Eau, les Glaces et l'Activité (OMEGA), and the Mars Advance Radar for Subsurface and Ionosphere Sounding (MARSIS). Additionally there are three instruments used for atmosphere analysis.
