Rank 78 documents Mars Global Surveyor — the first dedicated Mars mapping orbiter and the spacecraft that delivered the global topographic dataset every subsequent landing site debate still references. Launched 7 November 1996 aboard Delta II 7925 from Cape Canaveral, MGS entered Mars orbit 12 September 1997 after a four-month aerobraking campaign that circularized its path to 378 km altitude. Arden Albee's science team and Suzanne Smrekar's instrument leads operated MOC, MOLA, TES, and MAG/ER across more than nine years — mapping the entire surface repeatedly, finding gullies that suggested recent water flow, and relaying the bulk of Spirit, Opportunity, and Phoenix data home. Contact was lost 2 November 2006 when a solar-array fault ended the longest-running Mars mapper of its generation. Wallimilist renders the MGS bus over stippled Mars within the arched vintage frame, faded 1996 ghost numerals, and red MARS GLOBAL SURVEYOR title exactly as the master PNG dictates — mapping-orbit kicker, Delta II line, and curator copy on MOLA heritage and rover relay duty.
