Curiosity examines 'spiderweb' boxwork ridges on Mount Sharp; fourth sample sent to lab

NASA's Curiosity rover has imaged and sampled hilly 'spiderweb' boxwork ridges on Mount Sharp, capturing its fourth drilled sample from the feature set. Pending geochemical results aim to clarify Gale Crater's watery history and put recent organic detections into stratigraphic context.

Briefing

What Hype is tracking

  • Curiosity collected its fourth drilled sample specifically from boxwork ridges — results pending — a focused test of hypotheses about past aqueous alteration and habitability, building on recent detections of long‑chain organics that resist purely abiotic explanations (source:82660584-ac53-4adb-8fae-a9fca372347d).
  • High‑resolution imaging and new panorama context place these spiderweb‑like ridges within Mount Sharp stratigraphy, improving interpretation of local depositional and diagenetic environments crucial for reconstructing Gale Crater's watery past (source:9703bd92-d11c-4ae8-8e45-425e25a19e0d).
