MSL: APXS
(Alpha Particle X-ray Spectrometer)
|
March 17, 2026.
MSL Release 41 includes new APXS raw (EDR) and
derived (RDR) data from sols 4613 � 4709, July

|
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.
