Sol 571 - 573 Update On Curiosity From USGS Scientist Ken Herkenhoff: APXS the Observation Tray

17 March 2014

We had the option to perform contact science on Sol 571, but there were not compelling targets within the arm's reach, so an APXS integration on the observation tray was substituted. It had been over a year since such a measurement, which will be useful as a baseline before another sample is dumped onto the tray. I was supporting ChemCam planning for the weekend plan, focusing on fitting an RMI calibration activity into the plan, but the rover orientation was not ideal for this observation and we decided not to include it. The rover will drive again on Sol 572, followed by untargeted remote science on Sol 573.
