NASA Curiosity rover discovers honeycomb field on Mars

NASA's Curiosity rover captured images of an enormous field of **polygonal fractures with honeycomb-like textures** on the Martian surface in June 2026. The discovery was published by NASA JPL on approximately July 29-30, 2026, and quickly generated widespread media coverage. Mission scientists described the sight as having 'taken our breath away,' noting they had never seen so many of these features concentrated in one location at such scale.

The honeycomb field was found in a Martian valley nicknamed **'Valle Grande'** inside Gale Crater, the site where Curiosity has been exploring since landing in August 2012. Curiosity photographed the area on June 19-20, 2026, corresponding to **Sol 4930-4931** of the mission (a Sol is one Martian day). The images came from a 360-degree panorama taken as the rover began climbing the valley. Sources: NASA JPL, The Register.

Each polygon in the honeycomb field measures approximately **1.5 to 3 inches (4 to 8 centimetres) across**. While Curiosity had spotted small patches of similar polygonal fractures elsewhere on its traverse, the sheer scale and density of the features in Valle Grande is unprecedented in the mission's 14-year history.

Scientists have not confirmed a definitive cause. Three leading theories are under investigation: (1) **dried mud cracks** from an ancient lake or wetland environment that dried over geological time; (2) **thermal cycles**, repeated heating and cooling of the Martian surface causing the rock to expand and contract and crack into geometric shapes; (3) **pressure-driven changes** in sediments buried beneath the surface. The polygonal geometry is consistent with all three, and determining the true origin will require further analysis of the site's geology. Sources: NASA JPL.

Yes, Curiosity remains operational. As of July 2026, the rover has been active for nearly **14 years** and has traveled over **32 kilometres** across Gale Crater. However, mission engineers are monitoring a **cracked rear wheel** with more than 14 broken grousers (the metal cleats providing traction), photographed on Sol 4963 (July 23, 2026). JPL is assessing a 'rock-snap contingency' as wheel degradation approaches a threshold that could put onboard cabling at risk. The rover continues to send data and drive on Mars.

As of mid-2026, Curiosity is climbing through a valley area nicknamed **'Valle Grande'** in the upper layers of Mount Sharp (Aeolis Mons) at the centre of Gale Crater. The rover has been ascending Mount Sharp since 2014, studying layers of ancient rock that record billions of years of Martian geological and climate history. Sources: NASA JPL.

NASA's Curiosity rover landed on Mars on **August 6, 2012** inside Gale Crater, making it nearly **14 years old** as of mid-2026. It has far exceeded its original 2-year primary mission. The rover is nuclear-powered by a radioisotope thermoelectric generator (RTG), which means it does not depend on solar panels and can operate in dust storms and low-light conditions. Sources: NASA.

Both are NASA Mars rovers, but they operate independently on different areas of Mars. **Curiosity** landed in Gale Crater in 2012 and is now nearly 14 years into its mission, focused on habitability and geology in the layers of Mount Sharp. **Perseverance** landed in Jezero Crater in February 2021 with a different primary goal: collecting rock and soil samples to be returned to Earth by a future mission (Mars Sample Return). Perseverance also carried the **Ingenuity helicopter**, which flew dozens of times before losing contact. Sources: NASA.
