Talks and Calibration

Today at 2pm EST, NASA is hosting a media conference on Curiosity's progress. The stream will be accessible at JPL's UStream.tv channel.

Mars Science Laboratory Project Manager Richard Cook is lecturing at JPL's von Karman Auditorium at 10pm EST and will be broadcast live on JPL's UStream.tv channel as well.

Back at Sol 35 (Sep. 10, 2012), Curiosity continued self-tests, this time completing calibration of the APXS. The calibration target is carried at the front of the rover and is a small piece of basaltic rock from near Socorro, N.M.. The rock, held in a nickel mounting, was chosen because it is part of well-characterized rock on Earth and has low concentrations of sulfur, nickel, and chlorine, and is the hardest of the 200 candidates, making it an ideal calibration target. The absence of those 3 elements (S, Ni, and Cl) allows the team to account for the presence of dust on the sample. The opening is about 1.4" (3.5cm) in diameter.
