Scientists at the U.S. space agency, NASA, have unveiled dramatic photographs of a huge crater on Mars taken by the roving surface probe Opportunity.
On Friday, Opportunity sent back its first color panorama of Victoria, the 800-meter-wide Martian crater the rover reached last week after a 21-month trek.
NASA scientists told reporters Friday the sharp images of rock formations and soil layers open a window on the past of the planet. They say Victoria's exposed rock layers could help reveal the mystery of whether life existed on Mars.
NASA also displayed new photos taken by the Mars Reconnaissance satellite orbiting overhead, that included pictures of Victoria Crater and the Opportunity rover.
NASA researchers say they will use the photographs to plot the best route for the six-wheeled rover to descend into the crater.
