Sols 1129-1131: Assessing “Greenhorn”

9 October 2015

Curiosity is currently investigating an alteration zone around a fracture. After a successful drilling investigation at “Big Sky,” Curiosity is now ready to evaluate the alteration zone at “Greenhorn” for comparison.

The weekend plan is a busy one. The first sol is focused on SAM activities, to prepare a cup to receive the “Big Sky” drill sample, and then to drop off the sample. On the second sol Curiosity will use the DRT to clear off a fresh surface on "Greenhorn,” which we’ll image with MAHLI. Overnight, we’ll acquire APXS on “Greenhorn.” The main activity on the third sol will be CheMin analysis of the “Big Sky” sample. Throughout the weekend Curiosity will also take standard DAN, RAD and REMS measurements.

Meanwhile, I’ve been busy on the other side of the planet working MER operations, but I’ll be back on MSL next week so it’s good to keep an eye on all of the action!
