An ESA Moon probe, launched in 2003 September; the name is an abbreviation of Small Missions for Advanced Research in Technology 1. It took fourteen months to reach the Moon using a solar-electric propulsion system with xenon as a propellant, and went into a highly elliptical polar orbit in 2004 November. SMART-1 carried a miniaturized high-resolution camera (AMIE) for lunar surface imaging, a near-infrared point-spectrometer (SIR) for lunar mineralogy investigation, and a compact imaging X-ray spectrometer (D-CIXS) for surface composition studies. The mission ended in 2006 September, when it was commanded to hit the Moon.
