Comparison of grain size of the <150 μm sieved samples from the (left) Rocknest bedform and (right) Namib Dune. The <150 μm sieved fraction from Rocknest Scoop 5 was deposited on the rover's observation tray (portion of MAHLI image 0095MH0001310010101121C00; resolution ~21.1 μm/pixel). The <150 μm sieved fraction from Gobabeb Scoop 1 was deposited in discard pile A (portion of MAHLI image 1228MH0005630010403429C00; resolution ~16.7 μm/pixel, displayed reduced by 79.1% so as to be at the same scale as the Rocknest sample). Both images were acquired with the target materials fully shadowed by arm/turret hardware, then dynamic range stretched, and sharpened.
