But there may be questions about whether the rock characteristics found during an initial shallow “mini-drill” test late February 6 are suitable for deeper drilling and sample acquisition.

As part of the laboratory preparation process, the $70 million Goddard Space Flight Center Sample Analysis at Mars (SAM) instrument processed a “blank cell” this week to calibrate the instrument for its first analysis of powered rock coming as quickly as this weekend or early next week if the current target is found suitable.
