According to NASA this image shows part of the small pit or bite created when NASA’s Mars rover Curiosity collected its second scoop of Martian soil at a sandy patch called “Rocknest.” The bright particle near the center of this image, and similar ones elsewhere in the pit, prompted concern because a small, light-toned shred of debris from the spacecraft had been observed previously nearby. However, the mission’s science team assessed the bright particles in this scooped pit to be native Martian material rather than spacecraft debris.
They have decided to stop scooping soil until they have decided what this mystery object is. Hopefully soon we can all find out what this is and what it means for NASA’s mission on Mars.
