Curiosity Rover

NASA Mars Science Laboratory rover, landed August 2012 in gale-crater to assess past habitability of Mars. Operated by nasa-jpl. Sister mission to perseverance-rover (which landed at Jezero Crater in 2021).

Mission

Curiosity carries the sample-analysis-at-mars (SAM) instrument suite, which combines a gas chromatograph, quadrupole mass spectrometer, and tunable laser spectrometer to analyze rock samples in situ.

2026 organic-molecules result

In April 2026, an international team led by amy-williams (University of Florida) and including jennifer-eigenbrode of nasa-goddard published in Nature Communications that SAM detected more than 20 organic molecules in Glen Torridon mudstone drilled in 2020 — including a nitrogen-containing compound structurally similar to DNA-precursor bases and the sulfur-bearing aromatic benzothiophene. The detection used a one-shot TMAH wet derivatization run, the first such chemistry experiment performed on another planet. SAM carried only ~two cups of TMAH, forcing a high-stakes single-site choice (src-curiosity-mars-life-molecules-2026-04).

The team cannot distinguish biological, geological, or meteoritic origins; resolution requires mars-sample-return. The TMAH approach has been adopted for ESA’s rosalind-franklin-rover (Mars, 2028 launch) and NASA’s dragonfly-mission (Titan, 2027 launch) per the TIME-published follow-up by jeffrey-kluger (src-mars-organics-fresh-clues-2026-04). Kluger’s piece adds explicit exogenous-organics context: 2025 Nature Astronomy findings of 14 protein-forming amino acids in Bennu samples, and hexamethylenetetramine in the Murchison meteorite (1969). amy-williams frames the result as consistent with a combined “in-situ + exogenous” origin-of-life model.

Boxwork-region panorama (Nov–Dec 2025)

Per src-mars-two-sides-panoramas-2026-04, Curiosity captured a 360-degree panorama (1,031 images, Nov 9 – Dec 7 2025) of a boxwork-ridge region in the foothills of Mount Sharp — low ridges resembling giant spiderwebs formed by ancient groundwater depositing erosion-resistant minerals along bedrock fractures. The piece also surfaces an earlier Curiosity-team finding that the iron carbonate siderite may store CO₂ from a thicker early Martian atmosphere. By the April 2026 panorama release, Curiosity had left the boxwork region and was ascending into a sulfate-enriched layer of Mount Sharp.

2026 “Atacama” drill incident

On April 25, 2026, Curiosity attempted to drill a Gale Crater rock the team named “Atacama” (~13 kg / 28.6 lb, ~1.5 ft × 6 in). The entire rock lifted out of the surface and remained stuck to the fixed sleeve around the spinning drill bit — the first time in the mission a rock has stuck to the drill sleeve (previous drill incidents only cracked or layered rocks). After vibration-only attempts on April 25 and a re-positioned arm with vibration on April 29 failed to detach it, engineers freed the rock on May 1 with a combined maneuver of steep drill angle + rotation + vibration + bit-spinning; the rock fractured on landing (src-curiosity-rock-pulled-mars-2026-05).
