(Alpha Particle X-ray Spectrometer)
March 15, 2019.
MSL Release 20 includes new APXS raw (EDR) and
derived (RDR) data from sols 2128-2224, August 1 to
November 8, 2018.
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.
