NASA’s Perseverance, Curiosity Panoramas Capture Two Sides of Mars

Astrobiology.com (Keith Cowing, April 28, 2026) recap of paired 360-degree panoramas from Curiosity and Perseverance, 2,345 mi (3,775 km) apart. Curiosity’s mosaic (1,031 images, Nov 9 – Dec 7, 2025) shows a region of boxwork ridges on Gale Crater’s Mount Sharp formed by ancient groundwater depositing erosion-resistant minerals in bedrock fractures. Perseverance’s mosaic (980 images, Dec 18, 2025 – Jan 25, 2026) is centered on a site nicknamed “Lac de Charmes,” just outside Jezero Crater’s rim, capturing some of the oldest terrain in the solar system. The piece recaps recent results — the siderite carbonate clue for a thicker early atmosphere; the 2026 Glen Torridon organics inventory (21 carbon-containing molecules, seven new to Mars) covered in src-curiosity-mars-life-molecules-2026-04 and src-mars-organics-fresh-clues-2026-04; the 2024 Cheyava Falls “leopard-spot” rock from src-mars-perseverance-biosignature-2025; 23 onboard cores for mars-sample-return plus a 10-tube backup depot — and notes two surface firsts: audio of electrical sparks in passing dust devils and visible-light auroras from another planet’s surface. Curiosity has now left the boxwork region for a sulfate-enriched layer; Perseverance is heading toward “Singing Canyon.”

Key Claims

  • Curiosity and Perseverance sit 2,345 mi (3,775 km) apart and explore terrains “billions of years old”; Curiosity is moving up to younger Mount Sharp layers while Perseverance probes some of the oldest landscapes in the solar system.
  • Curiosity’s 360-degree panorama: 1,031 images stitched together, Nov 9 – Dec 7, 2025; centered on boxwork ridges — low ridges formed when groundwater deposited erosion-resistant minerals along bedrock fractures.
  • Perseverance’s 360-degree panorama: 980 images stitched together, Dec 18, 2025 – Jan 25, 2026; centered on “Lac de Charmes” outside Jezero’s rim.
  • Curiosity landed in Gale Crater in 2012; within a year, a drilled ancient-lakebed sample confirmed past habitability; Curiosity began ascending Mount Sharp (3 mi / 5 km) in 2014.
  • Curiosity team last year reported that siderite (iron carbonate) might be storing CO₂ from a thicker early Martian atmosphere.
  • Curiosity recently announced detection of three of the largest organic molecules yet found on Mars — long-chain hydrocarbons, possibly fatty-acid remnants — in a 2013 drill sample.
  • A 2020 drill sample contains the most diverse organic molecules yet found on Mars: 21 carbon-containing molecules, seven new to Mars.
  • Perseverance landed in Jezero Crater in 2021; in 2024 it found Cheyava Falls with “leopard-spot” patterns associated with microbial chemistry on Earth.
  • Perseverance keeps 23 intact rock cores onboard (chalk-sized) plus a 10-tube backup depot, awaiting mars-sample-return.
  • Perseverance recorded the first audio of electrical sparks in passing dust devils, and captured the first visible-light auroras from another planet’s surface.
  • Curiosity has left the boxwork region for a layer enriched in sulfate salts; Perseverance is heading for “Singing Canyon.”
  • Both rovers are built and operated by nasa-jpl (managed for nasa by caltech) under the Mars Exploration Program.

Notable Quotes

No on-the-record quotes; the piece is a NASA-style mission update.
