NASA's Mars rover Curiosity cut a wheel scuff mark into a wind-formed ripple at the "Rocknest" site to give researchers a better opportunity to examine the particle-size distribution of the material forming the ripple.
The director of NASA's Jet Propulsion Laboratory said last week that preliminary data showed the possibility that the agency's Mars Science Laboratory – the six-wheeled rover that landed on Mars in August — had found signs of carbon-containing molecules.
Gary Ross has penned and directed some big Hollywood hits like Big, Pleasantville and The Hunger Games. But for the past 15 years, his obsession has been something much more personal: a Dr. Seuss-ian children's book called Bartholomew Biddle and the Very Big Wind.
