These “boxwork” formations on Mars may look strange – but they exist on Earth, too (though they’re usually hidden inside caves). Initially spotted by orbiters, the Curiosity rover has been exploring this area up close. Here's what it found: jpl.nasa.gov/news/nasas-cur…

@NASAJPL Boxwork is like the leftover skeleton of mineral veins. Water moves through cracks, minerals fill the cracks, and later the softer rock erodes away so the harder mineral network stands out.

@NASAJPL Mars guy for scale?

@NASAJPL These “boxwork formations” on Mars, first seen from orbit, mirror rare cave formations on Earth. The Curiosity is now examining them up close, revealing intricate mineral patterns shaped by erosion and chemical deposition over eons. 🪐🪨

@NASAJPL Seeing structures like this on Mars suggests fluids once moved through these rocks. It makes you wonder what other stories the Martian surface is still hiding.

@NASAJPL A straight line, in nature??????

@NASAJPL Unlike Earth's smaller, cave-hidden boxworks, Mars' exposed versions reach 1-2 meters tall; Curiosity's sample analysis detected clays in ridges, carbonates in hollows, and organic compounds, hinting at complex chemical histories.

@NASAJPL I see Mars is already carving out future building plot lines for us

@NASAJPL Could Mars have once been a living world?

@NASAJPL good!

@NASAJPL it looks like a framework where homes were

Hosted by people living sober. Honest banter about recovery and life without alcohol. New episodes Thursdays.

@NASAJPL Beautiful Mars

@NASAJPL Doctored photos. Martian air is breathable …

@NASAJPL 🩷

@NASAJPL So awesome 😎

@NASAJPL Doesn't look that unusual tbh.

@NASAJPL 🤡

@NASAJPL @NASAMars One day we’ll know what happened!!

@NASAJPL too many straight lines in nature creeps me out
