RASC's annual Paul Sykes Memorial Lecture will be presented by Dr. Jim Whiteway, York University, Principle Investigator for the weather package on the Phoenix Mars lander.?Snow on Mars?
The NASA Phoenix mission landed on Mars in May 2008 and operated for five months. Instruments for atmospheric measurements were contributed from Canada, and one of these was a LIDAR that detected the backscatter of pulsed laser light. This measured the vertical distribution of atmospheric dust and water ice clouds. It was found that the atmosphere of Mars was similar to Earth in several ways. For example, dust in the atmosphere on Mars appears similar to what is observed above deserts on Earth. The LIDAR instrument also observed that water ice clouds form each night in late summer and that ice crystals precipitate to the surface. It snows on Mars! So now we know that precipitation plays a role in the hydrological cycle on Mars, as it does on Earth.
