"El Capitan": an Outcrop inside Eagle Crater - Sol 27
|
Caption NASA originale:"This graphic is a planning tool used by Mars Exploration Rover engineers to plot and scheme the perfect location to place the Rock Abrasion Tool on the rock collection dubbed "El Capitan" near Opportunity's landing site. "El Capitan" is located within a larger outcrop nicknamed "Opportunity Ledge. "El Capitan" was named after a mountain in Texas, but on Mars, it is about 10 cm (about 4") high. Scientists are eager to use the Rock Abrasion Tool to peer deeper into the history of the formation of "El Capitan" and the Team will spend multiple Soles taking pre- and post-measurements of the rock targets".
