Rover Arrives at Endeavor Crater on Mars
15.08.2011

What can the present-day terrain in and around large Endeavor crater tell us about ancient Mars? Starting three years ago, NASA sent a coffee-table sized robot named Opportunity on a mission rolling across the red planet's Meridiani Planum to find out. Last week, it finally arrived.

Inside Victoria Crater on Mars

Why are these strange little spheres on Mars? The robotic rover Opportunity chanced across these unusually shaped beads earlier this month while exploring a place named Kirkwood near the rim of Mars' Endeavor Crater.

A Path Into Victoria Crater on Mars
4.09.2007

What's inside Victoria Crater? Now that the dust has settled from the regional Martian dust storms that immobilized the rolling Martian rovers, the task ahead has become clear. Opportunity arrived at Victoria Crater last month and was poised to enter when the dust storms flared up unexpectedly.

A Berry Bowl of Martian Spherules
