The NHL announced the 2026 Bill Masterton Memorial Trophy nominees, with one player from each team recognized for perseverance, sportsmanship, and dedication to hockey; the list includes notable names such as Charlie McAvoy, Gabriel Landeskog, and Linus Ullmark, and the field will be narrowed to three finalists with a winner announced later.
Perseverance found nickel-rich rocks in Neretva Vallis (32 of 126 samples with nickel up to 1.1% by weight) often attached to iron-sulfide minerals and organic compounds, pointing to a water-influenced, reducing environment at Jezero Crater and making nickel potentially bioavailable for ancient Martian life, hinting at longer-lived habitable conditions.
NASA’s Perseverance rover found minuscule, 0.2 mm grains of chromium-bearing corundum inside pebbles near the rim of Jezero Crater on Mars. Using the SuperCam laser, scientists observed luminescent signatures indicating ruby- or sapphire-like material, though exact composition remains uncertain. The crystals are thought to have been delivered by meteorite impacts rather than formed in situ, and their discovery suggests Mars could host other precious minerals. Findings were presented at the Lunar and Planetary Science Conference in Texas.
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.
NASA’s Perseverance rover, using the RIMFAX ground-penetrating radar, uncovered buried, ancient river delta deposits beneath Jezero Crater dating to about 3.7–4.2 billion years ago—one of the oldest indicators of past liquid water on Mars and a crucial clue to the planet’s early habitability.
A first-time player overcomes self-doubt about who can tackle Soulslike games, battles through brutal early combat in Dark Souls Remastered, learns timing and enemy patterns, and ultimately defeats bosses like Taurus Demon and finishes the game—discovering that perseverance and learning are the game’s real lessons.
NASA’s Perseverance rover analyzed float rocks at Jezero Crater and detected signatures of corundum with chromium consistent with rubies. The crystals are extremely small (under 0.2 mm) and may be other corundum varieties such as sapphires, so a definitive identification can’t yet be made. Their origin is unclear, likely linked to high-temperature/high-pressure conditions from impacts or hydrothermal processes, and the rocks are out of their original context, requiring more samples for confirmation. Researchers note Mars may host other gemstone-bearing minerals in other areas as well.
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.
NASA’s Perseverance rover, using the RIMFAX ground-penetrating radar, uncovered a much deeper, older delta beneath Jezero Crater, suggesting Mars had flowing surface water long before the present delta and extending the window for past habitability and potential biosignatures in the subsurface.
Colin Dorgan, a high school hockey player who lost three family members in a Rhode Island rink shooting, scored the double-overtime game-winner to send Blackstone Valley Co-op past Portsmouth High School in the state semifinal.
NASA's JPL repurposed Perseverance's Helicopter Base Station to run a terrain-based localization algorithm that compares the rover's navigation-camera panoramas with onboard Mars terrain maps, delivering GPS-like positioning and enabling more autonomous navigation without constant Earth-based guidance. The test used the faster HBS hardware and found RAM bit faults, which were isolated to keep the algorithm reliable, showcasing Ingenuity-era hardware enabling new capabilities for the rover.
Two NASA missions—MAVEN in orbit and the Perseverance rover on the surface—have detected signals suggesting lightning or related electrical discharges in Mars' dusty atmosphere. MAVEN identified a rare whistler radio signal from a 2015 data set, while Perseverance recorded crackling sounds during dust storms likely from electrostatic discharges in charged dust clouds. Taken together, the findings strengthen the case that Mars experiences dust-driven electrical activity, with possible implications for atmospheric chemistry and the planet's environment, though large lightning bolts remain unlikely.
NASA’s Perseverance now uses an onboard system called Mars Global Localization to pin down its exact position on Mars by matching panoramic images to orbital terrain maps, achieving accuracy of about 25 centimeters. This allows the rover to navigate more autonomously and travel farther without Earth-based guidance, building on AI-driven planning and reducing reliance on ground control.
NASA's Perseverance rover can now determine its precise location on Mars autonomously using Mars Global Localization, matching navigation camera panoramas to orbital imagery in about two minutes to pinpoint its position within roughly 25 centimeters. This enables longer, safer drives without Earth-based input, complements existing auto-navigation, and signals broader use of onboard AI for future missions including lunar exploration.
New findings from NASA’s Perseverance in Jezero Crater suggest Mars during the Noachian epoch (about 4.1–3.7 billion years ago) was warmer and wetter than previously believed, with evidence of persistent rainfall indicated by kaolinite-rich clays and weathered rocks, challenging the cold, icy Mars theory and implying habitable conditions in the distant past.
