(Newser) – NASA’s Martian explorer Opportunity reached its first destination inside the cavernous Victoria Crater yesterday and prepared to get to work drilling into bright rock layers to collect data. The six-wheeled robot last month began the precarious decline into the crater, headed for a shiny piece of bedrock that scientists think is a relic of the ancient Martian surface, the AP reports.

Opportunity is now parked 40 feet below the rim at a 25-degree tilt—the steepest angle it has encountered since landing on the planet—while its sister rover Spirit explores a plateau on the other side of Mars for evidence of a volcano. The two robots, which landed on the planet three years ago, were originally slated for a three-month mission; this summer they survived a fierce dust storm that cut their power for weeks.
