Rank 14 documents Opportunity (MER-B) — the Mars Exploration Rover that landed 25 January 2004 at Meridiani Planum and confirmed past water through hematite concretions nicknamed blueberries. Opportunity drove 45.16 km over 14 years and 138 days, imaging its own heat shield and parachute debris, crossing Endurance and Victoria craters, reaching Marathon Valley, and descending Perseverance Valley before a global dust storm ended contact in June 2018. Steve Squyres' science team and JPL operators turned a 90-sol warranty into the longest Mars surface mission until surpassed by Curiosity. Wallimilist renders the Endurance rim hero, traverse map sol markers, and blueberry inset exactly as the master PNG dictates — MERIDIANS HEMATITE SITE label, 2004 kicker, and curator copy on MER-B endurance.
