Perseverance Inches Toward Martian Marathon as Old Rocks Come Into View

NASA’s Perseverance rover is nearing a 42.195-kilometer milestone on Mars, having traversed the Jezero Crater region for five years. It’s studying ancient rocks at Lac de Charmes, including the Arathusa outcrop, to uncover some of the planet’s oldest geology, such as megabreccia from a ~3.9-billion-year-old Isidis Planitia impact and possible volcanic features, with plans to push toward Gardevarri and Singing Canyon as the mission continues its ultramarathon-style exploration.

Perseverance Eyes Mars Ultramarathon as It Nears Record Distance

NASA’s Perseverance has driven more than 26.05 miles (41.92 km) on Mars over five years, closing in on Opportunity’s 28.06-mile record. After leaving Jezero Crater, it’s pushing into Lac de Charmes with future stops like Gardevarri and Singing Canyon, inching toward what could become the rover’s ultramarathon finish line later this month.

Perseverance Captures Sixth Selfie From Mars' Lac de Charmes, Highlights Ancient Rocks

NASA’s Perseverance posted its sixth selfie from Mars, taken from the Lac de Charmes region west of Jezero Crater and assembled from 61 images by the WATSON camera as the rover continues its westward trek. In addition, a 46‑image Mastcam-Z panorama of the Arbot area provides a detailed look at ancient rock formations, including megabreccia tied to a 3.9‑billion‑year‑old Isidis Planitia impact, helping scientists study the oldest rocks the mission will examine.

Perseverance Ventures Into Mars’ Deep Crust, Uncovering Ancient Rocks

NASA’s Perseverance rover has pushed beyond Jezero Crater into the Lac de Charmes region, capturing a selfie and surveying ancient, potentially igneous rocks that could illuminate Mars’ deep crust and early volcanic history. With almost 26 miles traveled and 27 rock cores collected (25 sealed for potential return), the mission shifts toward studying Mars’ primordial interior, with future targets like Gardevarri and Singing Canyon expected to reveal more about the planet’s infancy.

Perseverance Captures 61-Frame Selfie While Probing Ancient Martian Rocks

NASA’s Perseverance stitched 61 images into a self-portrait at Lac de Charmes on the western Jezero Crater rim, focusing on the Arethusa outcrop to study ancient Martian rocks; taken March 11, 2026 (Sol 1797) with the WATSON camera, it’s the rover’s sixth selfie and part of its Northern Rim Campaign. A separate 46-image Mastcam-Z panorama of Arbot (April 5, Sol 1882) highlights diverse rock textures and megabreccia, informing Mars’ early crust and potential volcanic history. After more than five years, the rover has driven about 26 miles and collected many rock cores, underscoring a marathon-like mission pace.

NASA rovers reveal parallel Martian histories in paired panoramas

NASA released two 360-degree panoramas from the Perseverance and Curiosity rovers—assembled from nearly 1,000 images each—that contrast two Martian environments: Perseverance’s ancient lake and delta at Jezero Crater and Curiosity’s boxwork-rich terrain in Gale Crater. The pair highlights Mars' watery past and prebiotic chemistry, with Perseverance seeking signs of past life and Curiosity studying habitability while continuing to map the planet’s geological timeline.

Mars in Two Ages: Curiosity and Perseverance Spotlight Different Eras in 360 Panoramas

NASA's Curiosity and Perseverance released separate 360-degree panoramas showing Mars' long history: Curiosity's view over boxwork ridges in Gale Crater reveals groundwater-formed rock as it climbs Mount Sharp, while Perseverance's Lac de Charmes panorama around Jezero Crater captures ancient rocks in one of the oldest landscapes on the planet. Both rovers continue collecting data and samples to unravel Mars' past habitability and potential for life, with Curiosity probing mineral evidence and Perseverance storing and studying samples for eventual Earth-based analysis.

Martian Nickel Clue: Perseverance Uncovers 3-Billion-Year-Old Rocks with Rare Mineral Signatures

NASA’s Perseverance rover found unusually high nickel levels (up to 1.1% by weight) in rocks from Neretva Vallis in Jezero crater, dating about 3 billion years, with nickel‑rich minerals in magnesium‑sulfate veins that resemble Earth’s pyrite. While this hints at a chemical environment that could support microbial processes, it does not prove life on Mars; the nickel’s origin is uncertain and requires further study.

Mars Pebbles Reveal First Corundum Grains, Hinting at Impact-Driven Gem Formation

Mars Pebbles Reveal First Corundum Grains, Hinting at Impact-Driven Gem Formation

NASA’s Perseverance rover detected microscopic grains of corundum (the mineral behind rubies and sapphires) in rocks along the Jezero crater rim using the SuperCam laser system, marking the first confirmed corundum on Mars. The grains, under 0.2 mm, were found in Hampden River and similarly detected in Coffee Cove and Smiths Harbour, suggesting corundum is present in multiple spots. Mars’s lack of plate tectonics makes Earth-like formation unlikely, so scientists propose meteorite impacts as a plausible source of the high-temperature/pressure conditions that yield corundum. Further sampling is needed to confirm origin and formation details; findings were presented at the Lunar and Planetary Science Conference.

Jezero Rock Sparks Cautious Hopes of Ancient Martian Life

Perseverance detected two minerals, vivianite and greigite, in a Jezero Crater rock, a tantalizing but unproven biosignature that could indicate a past microbial ecosystem; abiotic processes could mimic such signals, so confirmation is essential. A Mars Sample Return would bring rocks to Earth for high-resolution analyses—NASA and partners are pursuing faster, cheaper routes to achieve this within a decade. If confirmed, it would be historic; even a null result would inform the conditions under which life could arise on Mars.

Radar Uncovers Hidden Ancient Delta Beneath Martian Jezero Crater

NASA’s Perseverance rover’s ground-penetrating radar detects what appears to be an ancient subsurface river delta buried beneath Jezero Crater’s Margin unit, dating to the Noachian era. The deep, layered clinoforms suggest long-lived aqueous conditions and potential habitats for past life, though alternative volcanic or shoreline explanations are also considered. This finding broadens Jezero’s known watery history, with more data from Perseverance yet to come.
