A close-up of Cacao as viewed through Curiosity’s ChemCam instrument. The red circle represents part of the meteorite targeted by the instrument’s laser.And Cacao is distinct from its surroundings. Unlike the red oxide-covered surroundings, the meteorite is dark grey and metallic-looking. Curiosity's Mast Camera, or Mastcam, took the panorama with its 100-millimeter focal length lens. The panorama is made up of 19 images stitched together after being sent to Earth,.
Cacao contains evidence of having passed through an atmosphere composed of regmaglypts, grooves, and pits on iron meteorites. The regmaglypts are likely created by vortices of hot gas that melted the rock as it passed through the atmosphere,A more zoomed-in close-up of Cacao as viewed through ChemCam; the red targets are where the instrument’s laser zapped this meteorite.However, the team stressed that there was no way to date the meteorites, and they could have been there for millions of years.
