This artist's concept shows the Indian lunar orbiter Chandrayaan-1. The spacecraft will carry two European experiments on board which are direct descendents of ESA's SMART-1 - the infrared spectrometer, SIR2, and the X-ray spectrometer, C1XS, to study the mineralogy and the chemical composition of the lunar surface. The third European instrument on board is the SARA Sub-kiloelectronvolt Atom Reflecting Analyser, that will study the interaction between the lunar surface and the solar wind.
