A 'Pot of Gold' Rich with Nuggets

This close-up image taken by Spirit highlights the nodular nuggets that cover the rock dubbed "Pot of Gold."

June 25, 2004

This close-up image taken by the Mars Exploration Rover Spirit highlights the nodular nuggets that cover the rock dubbed "Pot of Gold." These nuggets appear to stand on the end of stalk-like features. The surface of the rock is dotted with fine-scale pits. Data from the rover's scientific instruments have shown that Pot of Gold contains the mineral hematite, which can be formed with or without water.

Scientists are planning further observations of this rock, which they hope will yield more insight into the hematite's origins as well as how the enigmatic nuggets formed.

This image was taken by Spirit's microscopic imager on sol 163 (June 18, 2004). The observed area is 3 centimeters by 3 centimeters (1.2 inches by 1.2 inches).

Drive along with NASA’s Opportunity Mars rover and hear the voices of scientists and engineers behind the mission. Designed to run for 90 days, the exploration spanned more than 15 years from 2004 to 2019. Along the way, it discovered definitive proof of liquid water on ancient Mars and set the off-world driving record.
