The Latest Weather Report from Mars

This figure compares preliminary atmospheric surface pressures recorded by the Pathfinder MET experiment with pressures acquired at the same season and time of day by the Viking 1 lander. Pressure is given in millibars and time is local time of day at the lander site. This figure compares preliminary atmospheric temperatures recorded by the Pathfinder MET experiment with temperatures acquired at the same season and time of day by the Viking 1 lander. Temperature is given in Kelvin and time is local time of day at the lander site.

This figure shows the entry vehicle deceleration in g's along its flight path during the entry phase of the mission. As the probe enters at 7.5 km/second, the deceleration forces produced by the atmosphere range from less than 10 micro g at time 0 (160 km) to about 20 g at 100 seconds (25 km). The deceleration pulse produced by parachute deployment is clearly seen at 185 seconds (10 km).
 This figure shows entry vehicle deceleration in g along its flight path during the entry phase of the mission. Deceleration is plotted in logarithmic coordinates to reveal accelerations in the range 0.00001 to 20 g. These measurements allow the atmospheric density, pressure and temperature profiles to be calculated.
