NASA’s Opportunity at 10: new findings from old rover

In the Jan. 24 edition of the journal Science, Ray Arvidson, PhD, a professor at Washington University in St. Louis and deputy principal investigator of the MER mission to Mars, writes in detail about the discoveries made by the Opportunity rover and how these discoveries have shaped our knowledge of the planet.

New Mars rover’s mechanics to be used to study Martian soil properties

NASA has announced that Raymond E. Arvidson, PhD, a planetary scientist at Washington University in St. Louis, has been selected to be a participating scientist on the Mars Science Laboratory, a mission to land and operate a rover named Curiosity on Mars. Arvidson proposed that he use the rover itself as a terramechanics instrument to learn about Martian soils. He will be using a simulation of the rover and of the Martian terrain to contribute to path planning for the rover and to look for crusted soils created by the modern Martian water cycle.
