MSL: APXS (Alpha Particle X-ray Spectrometer)

May 9, 2013. The APXS RDR Software Interface Specification is now posted on the APXS P.I.'s web site at the University of Guelph, and on the PDS archive here.

March 28, 2013. The APXS EDR Software Interface Specification has been cleared and is now posted on this site. There are no other APXS EDR documents waiting for clearance.

March 20, 2013. MSL Release 1, part 2, includes APXS derived (RDR) data from sols 0-89.

Like the APXS EDR data, the APXS RDR data are considered by PDS to be "In Lien Resolution" while some of the liens from the RDR peer review are still being addressed. As the liens are minor, the APXS RDRs are classified as Certified Data in PDS. These terms are defined on the Geosciences Node Holdings page.

March 8, 2013. The MSL EDR Archive Volume Software Interface Specification has been cleared and is now posted on this site.

February 27, 2013. MSL Release 1 includes APXS raw (EDR) data from sols 0-89.

 The APXS EDR data have undergone a PDS peer review. Some of the recommendations from the review are still being addressed, so this data set is considered by PDS to be "In Lien Resolution". As the remaining liens are minor, the APXS EDRs are classified as Certified Data in PDS. These terms are defined on the Geosciences Node Holdings page.

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.
