NASA Finds Broad, Shallow Pits During Curiosity’s Mars Traverse
NASA’s Curiosity rover found unusual holes on Mars.
They were wide but not very deep.
They looked different from the craters made by falling space rocks.
Scientists did not see obvious objects inside the holes.
Curiosity used special cameras to photograph them closely.
The pictures were combined to make 3D models.
Scientists are studying the holes and nearby rocks to understand how this part of Mars formed.
The discovery shows that Mars can still surprise researchers.
NASA’s Curiosity rover spotted broad, shallow pits in Valle Grande on Mount Sharp.
The pits looked unlike typical meteorite impact craters and lacked obvious objects inside them.
MAHLI photographed the formations at close range, while Mastcam imaged nearby terrain.
Scientists combined and processed the images to create three-dimensional surface models.
ChemCam, MAHLI, and APXS also studied unusual gray rocks and layered bedrock.
- Who
- NASA scientists and the Curiosity rover, with observations described by Dr Michelle Minitti.
- What
- The rover discovered broad, shallow pits and studied unusual layers and gray rocks.
- Where
- Valle Grande on Mount Sharp, inside Gale Crater on Mars.
- When
- During Curiosity’s traverse, after the rover had spent 14 years on Mars; the exact date was not stated.
- Why
- To investigate the pits and understand the geological processes and chemical differences affecting the rocks.
Key facts
- Discovery
- Broad, shallow pits were observed across the Martian surface.
- Location
- Valle Grande on Mount Sharp inside Gale Crater.
- Primary rover
- NASA’s Curiosity rover.
- Imaging instruments
- The Mars Hand Lens Imager (MAHLI) and Mastcam photographed the area.
- Analysis method
- Images were combined and processed into three-dimensional surface models.
- Additional instruments
- ChemCam, MAHLI, and APXS analyzed layers and gray float rocks.
- Scientific uncertainty
- The articles describe the pits as a new puzzle and do not identify their origin.
