It cannot be seen through the rainclouds, but somewhere up in the sky, two rovers are driving around on Mars collecting data. Yesterday, students and faculty had to go no farther than Goldwin Smith Hall to reap the benefits. Prof Steve Squyres Ph.D.’78, astronomy, who is the mission’s science team leader, gave an overview of the mission to a packed audience in the Hollis E. Cornell Auditorium and explained how the rovers work and what they have found.
