Haha that guy has found the coolest hobby in the world, :thumb_up: It seems weird how someone could have the spatial awareness to create those with such accuracy while inside the pattern and not being able to see it from a better perspective.. I guess it's all about fixed points and counting your steps.
*edit* hm, I guess I should post a picture now, here's a little fella I met one day
Yeah, you would have to be extremely mechanical in your movements. Like a walking meditation. I bet the mindspace for doing this kind of work is a simple, focused, blissful mathematical space...
This color full-resolution image showing the heat shield of NASA's Curiosity rover was obtained during descent to the surface of Mars on Aug. 5 PDT (Aug. 6 EDT). The image was obtained by the Mars Descent Imager instrument known as MARDI and shows the 15-foot (4.5-meter) diameter heat shield when it was about 50 feet (16 meters) from the spacecraft.
This image shows the inside surface of the heat shield, with its protective multi-layered insulation. The bright patches are calibration targets for MARDI. Also seen in this image is the Mars Science Laboratory Entry, Descent, and Landing Instrument (MEDLI) hardware attached to the inside surface.
At this range, the image has a spatial scale of 0.4 inches (1 cm) per pixel. It is the 36th MARDI image, obtained about three seconds after heat shield separation and about two and one-half minutes before touchdown. The original image from MARDI has been geometrically corrected to look flat.
Isn't it mind boggling that we as the human race have the technology to capture images of our spacecraft descending into an alien planet?
