  • Mars overview
    Martian surface while a wider view shows that the surface roughness varies with wind direction Winds coming toward the lander from 120 either side of the optimum wind direction will be less disturbed than winds from the remaining 120 where the flow is over the solar panels and the rest of the lander The solar panels absorb almost all of the solar energy converting about 20 to electricity The remaining 80 of the absorbed solar energy heats the solar panels which in turn heats the adjacent ground and the atmosphere The lander and the Martian surface temperatures differ during both during daytime heating and night time cooling These effects cause the air temperature measured by the meteorology sensors to differ from the temperature that would be measured over the nearby surface especially for directions passing over the lander and even more for light winds Images J Maki others Pathfinder IMP Team NASA JPL On the Viking landers similar atmospheric temperature measurement problems occurred even though the lander was painted white Its power source was a Radio Isotope Thermoelectric Generator RTG producing about 50 watts of electricity and 900 watts of heat from radioactive decay this excess 900 watts heats the lander and the air RTG power sources dramatically simplify the design and reduce the cost of Mars Spacecraft and allow us to conduct missions that are impossible with solar power If Pathfinder had a RTG or even a RHU Radioactive Heater Unit it might have lasted far longer and been able to communicate with its lonely wandering Sojourner for many more months Part of this heat was used to maintain the Viking landers interior warm with temperatures in a range that would be comfortable for a space suited human and ideal for the instruments The rest was transferred to the air from the lander and from heat dissipating fins on the RTG During very light wind conditions air flowing over the lander was heated by as much as 10 C causing errors in the measurements of atmospheric temperature Due to the length of the boom and placement of the sensors Lander Interferrence errors are minimum for the best two thirds of the wind directions When the winds reach 10 meters second 22 miles hour the errors also are small The image below which is to the right of the image above shows a gully indicating water erosion occurred directly in front of the rover ramp The tilted flat surface rocks also imply that a very strong flow occurred here Please refer to one of the Pathfinder mirror sites for the latest Pathfinder information nbsp Meteorological Highlights Atmospheric pressure on Mars is approximately 1 of that on Earth and varies about 15 during the year due to condensation and sublimation of its primarily CO 2 atmosphere described in detail below Other aspects of its meteorology evident in the figure of the annual cycle of pressure are the increasing day to day pressure variations between fall and spring which are weather fronts
