MSL: APXS (Alpha Particle X-ray Spectrometer)

March 17, 2014. MSL Release 5 includes new APXS raw (EDR) and derived (RDR) data from sols 360 through 449.

The Alpha Particle X-ray Spectrometer (APXS) measures the abundance of chemical elements in rocks and soils. The APXS is placed in contact with rock and soil samples on Mars and exposes the material to alpha particles and X-rays emitted during the radioactive decay of the element curium. APXS data sets are produced by the APXS Science Team at the University of Guelph, Ontario, Canada. The APXS is funded by the Canadian Space Agency.
