Temperature Sensor Readings (IMAGE) NASA/Goddard Space Flight Center Caption The chart on the left is showing temperatures for a SAM actuator, starting at Martian sol 2,055, which was May 18 on Earth. The diagonal lines that form a cone starting on sol 2,085 show Benito Prats' predicted actuator temperature range through sol 2,180, or Sept. 23. The vertical blue lines that fill the cone are actual motor temperature readings. The dust storm was classified as global on June 20, or sol 2,088. By that point, the actuator temperature had changed drastically, as is clear in the relatively sudden narrowing of the chart, indicating cooler daytime temperatures and warmer night-time temperatures. The chart on the right is the same, but shows actual temperature readings through sol 2,180, or Sept. 23.
