Oxychlorine Species on Mars: Implications from Gale Crater SamplesEvidence of oxychlorine species such as perchlorates or chlorates have been detected in nearly every acquired sample analyzed on the surface of Mars. Perchlorates were first discovered by the Wet Chemistry Laboratory (WCL) instrument on the Phoenix lander in 2008. The Sample Analysis at Mars (SAM) instrument on the Mars Science Laboratory (MSL) has analyzed twelve samples from Gale Crater (as of July 2016), nine drilled samples and three scooped samples. After delivery to SAM, samples are heated to approximately 850 C and evolved gases are measured by a quadrupole mass spectrometer.
