NASA’s Curiosity Discovers a Field of Martian Polygons

Description NASA’s Curiosity Mars rover captured this 360-degree view of an expanse of terrain covered in surface features called polygons on June 19 and 20, 2026, the 4,930th and 4,931st Martian days, or sols, of the mission.

The top 3

  1. Evidence of Ancient Lakes and Rivers: NASA's Curiosity rover found chemical and mineral evidence in Gale Crater, like fine-grained mudstone sediments, indicating ancient tranquil lake environments and river deltas, while Opportunity found rocks formed at the shoreline of an ancient salty body of water.
  2. Discovery of Organic Molecules: Curiosity has identified the most diverse collection of organic molecules ever found on Mars, including nitrogen heterocycles which are considered precursors to RNA and DNA, and long-chain hydrocarbons, strengthening the possibility of past life.
  3. First Direct Evidence of Past Microbial Life Potential: Curiosity's findings in Yellowknife Bay confirmed that ancient Mars had the chemical building blocks and environmental conditions, including fresh water with near-neutral pH, suitable for microbial life.
