摘要

In August 2003, NASA selected Phoenix as the first of its low-cost, science driven missions under the Mars Scout program. Scheduled for launch in 2007, Phoenix will land in the northern Vastitas Borealis region to assess the astrobiological potential for life at high latitudes. In particular, it will verify the recent discovery of possible subsurface water ice detected by the gamma ray spectrometer aboard the orbiting Mars Odyssey spacecraft. Phoenix will also investigate the mineralogy and geochemistry of the soil and measure the properties of the atmosphere and planetary boundary layer. Canada's contribution to the Phoenix mission will be a Meteorological Station (MET). This system will consist of a lidar (light detection and ranging) instrument that will characterize boundary layer turbulence and dust and cloud circulation in the near-surface atmosphere. The MET will also measure atmospheric pressure and temperature and its lapse rate thereby providing the first surface measurements of these parameters in this Northern region. This paper summarizes the current status of the MET development, provides details about the instrument and describes Canada's participation in the project.
