I can help to give a better sense of what the size of these things are from the OP's pictures.
First, here's a link to the actual page (not just the image) that the OP got the image from:
Diversity in Vicinity of Curiosity's First Drilling Target
Second, while the OP did provide a link to one of the images on that page, they failed to give you a link that is very, very important:
Full resolution image that shows scale
*WARNING: This file is over 200 MB big. Below is a smaller, cropped version of it.
As you can see, the entire view is only a few meters wide. The "cave" is only a few meters away.....and is a very small depression in the rock.
How do I know this?
Because what the OP also failed to tell you is the back ground of these images, which they are a mosaic of many images that were taken by Curiosity on
With that information, you can go take a look at the original image for the "cave" at this link:
Image from Curiosity Mast Cam, Sol 138
Here is what it looks like:
So the "cave" is nothing more than several different rocks, less than a meter wide with some shadowing.....
The "Toy" is also located in the pictures of Sol 138 and if you look at the original image, it's a porous rock that measures a few centimeters.
Oh, and here is the article from my first link about the mosaic:
The right Mast Camera (Mastcam) of NASA's Curiosity Mars rover provided this contextual view of the vicinity of the location called "John
Klein," selected as Curiosity's first drilling site. The distance from the camera to John Klein was about 16 feet (5 meters). The scale bar is 150
centimeters (59 inches) long. This mosaic was assembled from images acquired on Sol (or Martian day) 138 between 8:30 and 9:25 in the morning, local
Mars solar time (on Dec. 25, 2012). It illustrates the diversity of rock types from which the rover team could choose to sample. The enlargements of
rocks seen on the right, and denoted by letters and boxes within the left image, represent this diversity. Each box is about 9 inches (22 centimeters)
square. Enlargement A shows a "bread-crusted" rock, whose surface is fractured in a polygonal pattern. This generally reflects a differential change
in volume of a rock, with the outer part expanded relative to the interior. Enlargement B is representative of the material that will be sampled at
the John Klein site, showing both light-toned veins and dark spots that show the relief of concretions. Enlargement C shows an exotic black rock that
is similar in shape to more distant, dark rocks found higher in the local stratigraphy. That rock was probably emplaced here as part of material
ejected by a crater-excavating impact. The image has been white-balanced to show what the rocks would look like if they were on Earth.
It helps to actually have all the information and to actually do some RESEARCH before making wild claims about things. Especially since others on here
WILL go do that research and find what has been left out of a thread's OP.......
