Curiosity, 고대 모래폭풍 증거 발견

수십억 년 전 수시간에 걸친 강력한 화성 모래폭풍으로 모래 물결이 서로 겹치며 퇴적층을 형성했고, 이 퇴적층이 경화되어 Curiosity가 촬영한 다층암이 되었습니다. 이미지는 2024년 12월 12일(마스 데이 4,391일)에 촬영되었습니다.

These layers of sediment eventually hardened into the multilayered rocks seen in this image, which was taken by NASA’s Curiosity rover on Dec. 12, 2024, the 4,391st Martian day, or sol, of the mission. Scientists believe this is the first evidence of climbing wind ripple strata on the Red Planet. Spotted at a location nicknamed “Jawbone Canyon,” these rocks are a rare time capsule preserving a dramatic wind event early in Martian history. A paper detailing the discovery was featured on the cover of the journal Geology on July 1, 2026.
