Image caption: Time lapse context view of Curiosity maneuvering her robotic arm. Curiosity conducts a close- up examination of windblown ‘Rocknest’ ripple site and inspects sandy material at “bootlike” wheel scuff mark with the APXS (Alpha Particle X-Ray Spectrometer) and MAHLI (Mars Hand Lens Imager) instruments positioned on the rotatable turret at the arm’s terminus. Colorized mosaic was stitched together from Sol 57 & 58 Navcam raw images shows the arm in action just prior to 1st sample scooping here. Surrounding terrain and eroded rim of Gale Crater rim is visible on the horizon.
