Six instruments will be operating in all mission phases (cruise/lunar), performing 10 distinct science and technology investigations (Table 1). Science instruments, led by Principal Investigators (PIs) were mostly funded from PIs and co-Is national sources. Technology Experiments, led by Technology Investigators (TIs) were partly funded by ESA. Three instruments are used for spacecraft and planetary environment studies: Electric Propulsion Diagnostic Package (EPDP), Spacecraft potentialPotential, Electron and Dust Experiment (SPEDE) and Radio Science Investigation with SMART-1 (RSIS). Lunar exosphere studies are planned for EPDP and SPEDE. Three instruments are used for lunar remote sensing: the global X-ray mapping spectrometer (D-CIXS), near infrared spectral mapping spectrometer (SIR), and the localised high spatial resolution colour imaging camera of the lunar surface (AMIE). Overall science objectives for the mission are shown in Table 2.
