Exploring the Surface of Mars with Spirit, Opportunity and Curiosity.

Opportunity at a Vista Point

Bill Farrand Ph.D., Space Science Institute

The landing of the Spirit and Opportunity rovers on Mars in January 2004 began a new era in the surface exploration of Mars. These rovers were targeted respectively to Gusev crater and to the dark plains of Meridiani Planum. Both rovers vastly exceeded their nominal missions with Spirit exploring until 2010 and Opportunity still in operation and now exploring the rim of the ancient Endeavour crater.  In their missions, Spirit discovered abundant evidence of the action of water including silica-rich hydrothermal deposits.  Opportunity discovered evidence of the surface flow of water, the action of acidic waters in the subsurface of Mars, and examined clays and gypsum veins on the rim of Endeavour crater.  Spirit and Opportunity were joined on Mars by the larger Mars Science Laboratory Curiosity in 2012. Curiosity was targeted to Gale crater and has discovered evidence of surface water flow, long standing lakes and potentially habitable environments. Curiosity’s mission continues as it is making its way up the slopes of Mt. Sharp, rising 3.4 miles (5.5 km) above the floor of Gale crater and containing clay and sulfate minerals indicative of an earlier, water rich environment.  All three rovers have helped to transform our view of the surface of Mars from a barren, dead volcanic planet to one that was once much like the Earth with flowing ground and surface waters and stunning scenic vistas.

Bill Farrand, Ph.D., Space Science Institute

Bill Farrand is a senior research scientist at the Space Science Institute in Boulder, Colorado. He has a B.A. in Geology from Franklin & Marshall College and a M.S. and Ph.D. in the Geosciences from the University of Arizona. He has worked extensively in terrestrial remote sensing as well as in the remote sensing of Mars and of the Moon. In the terrestrial remote sensing field, Bill has worked extensively with data from airborne hyperspectral remote sensing systems for both commercial and government programs. Bill has been a Participating Scientist on NASA’s Mars Exploration Rover (MER) Mission since 2002. Bill has worked extensively with multispectral Pancam data from both the Spirit and Opportunity rovers looking at the multispectral reflectance of rocks viewed by the rovers at the Columbia Hills of Gusev crater and on the plains and craters of Meridiani Planum. He is also involved in several other projects examining terrestrial analogues of Martian surface materials, working with orbital remote sensing data of Mars, and examining the hyperspectral reflectance data over mining sites in western India.  In his free time, Bill is an avid rock climber and also enjoys skiing, hiking, taking his dogs on walks, and pursuing useless TV and movie trivia.
