A Top 10 Decade 1 Discovery by NASA’s Twin Mars Exploration Rovers

Carbonate-Containing Martian Rocks discovered by Spirit Mars Rover

Spirit collected data in late 2005 which confirmed that the Comanche outcrop contains magnesium iron carbonate, a mineral indicating the past environment was wet and non-acidic, possibly favorable to life. This view was captured during Sol 689 on Mars (Dec. 11, 2005). The find at Comanche is the first unambiguous evidence from either Spirit or Opportunity for a past Martian environment that may have been more favorable to life than the wet but acidic conditions indicated by the rovers’ earlier finds.

January 2014 marks the 10th anniversary since the nail biting and history making safe landings of NASA’s renowned Mars Explorations Rovers – Spirit and Opportunity – on the Red Planet barely three weeks apart during January 2004.

Due to their completely unforeseen longevity, a decade of spectacular and groundbreaking scientific discoveries continuously flowed from the robot sisters that have graced many articles, magazine covers, books, documentaries and refereed scientific papers.

What are the Top 10 Decade 1 discoveries from Spirit and Opportunity?

Find out below what a top Mars rover team scientist told Universe Today!

Ray Arvidson, the rovers Deputy Principal Investigator and professor at Washington University in St. Louis, has kindly shared with me his personal list of the Top 10 discoveries from Spirit and Opportunity for the benefit of readers of Universe Today.

The Top 10 list below are Ray’s personal choices and does not necessarily reflect the consensus of the Mars Explorations Rover (MER) team.

First some background.

The dynamic duo were launched on their interplanetary voyages from Cape Canaveral Florida atop Delta II rockets during the summer of 2003.

The now legendary pair landed on opposite sides of the Red Planet. Spirit landed first on Jan. 3 inside Gusev Crater and twin sister Opportunity landed second on Jan. 24 on the dusty plains of Meridiani Planum.
