I talked to engineer Ariel S. of NASA-GSFC  and discussed how the Sample Analysis at Mars (SAM), onboard NASA's Mars Science Laboratory rover, Curiosity, works. Ariel is a fellow countryman from Argentina and was gracious enough  to talk to me between  real-time test runs and showed me the behind the scenes of different laboratories. 
Here are the two short videos one in English and the other one in castellano/español as Ariel explains the workings of SAM.  The  sound has some background noise as the testbed is running, but it is still audible. This is real science and technology in action. Amazing! Thank you so much Ariel.
