A few Martian days after taking the first asteroid picture (see yesterdays post)Curiosity arrived at a place called “Windjana”.
Windjana is a about 60 cm wide (about 2 ft) on the right half of the image and is a target for a close-up examination and perhaps a drilling to see what’s inside. Have to like being able to do that. Another remarkable thing about this picture is how clean Curiosity is after 609 Martian days.
The sandstone target’s informal name comes from Windjana Gorge in Western Australia. If this target meets criteria set by engineers and scientists, it could become the mission’s third drilled rock and the first that is not mudstone.
The rock is within a waypoint location called “the Kimberley,” where sandstone outcrops with differing resistance to wind erosion result in a stair-step pattern of layers. Windjana is within what the team calls the area’s “middle unit,” because it is intermediate between rocks that form buttes in the area and lower-lying rocks that show a pattern of striations.
