Curiosity’s Contact Science Kicks Off with Challenge of Bilko Pinnacle, New Approach to Examine Pipsqueak Spire and Nighttime APXS Observations

In our first sol of the mission, remote science activities are the focus. ChemCam is conducting LIBS mosaics of “May Lake” and “Pavilion Dome,” two small tilted blocks, as well as a 3×3 RMI mosaic of a cluster of dark pyramidal blocks in the distance. Meanwhile, Mastcam is capturing large mosaics of two targets on Pinnacle Ridge and “Sharktooth Peak,” a cluster of blocks we will explore in the future.

Following a break, Curiosity will perform contact science on the Bilko Pinnacle target. This task is challenging due to the block’s height, steep sides, and rough surface with bumps and pits, making it impossible to brush. To create detailed 3D images, MAHLI images are being taken from three different orientations, as well as a 5cm stereo pair and a 2cm close approach.

Next, Curiosity will examine Pipsqueak Spire, a small light-toned rock that is too close to the rover for a normal 25cm standoff. To get up-close views without damaging the rock, we have used an alternative approach with a 20cm and 5cm stereo pair instead. Nighttime APXS observations are planned for both targets before the arm is stowed away to make way for contact science activities.

After completing contact science activities, CheMin will conduct an analysis on an internal calibration standard to ensure accurate data collection and track performance throughout the mission.
