The Martian Calendar
For a discussion on analemmas, see http://plus.maths.org/content/how-long-day. The photo below of a Martian analemma is taken from that site. The next phase of my research will attempt to link the height of the sun above the Martian horizon, Martian lander latitude, surface temperatures as they vary by season on Mars, and pressures. In particular, I will look at what effect insolation would have on a small amount of Martian air that was trapped in the narrow tube leading up to Tavis and Vaisala pressure transducers. The question is, if during the moments before landing, the tube in question starts to draw in dust in addition to Martian air, some clogging the filter almost but not quite immediately, with larger clumps sticking in closer to the intake, how much will air pressure vary with temperature in the tube, assuming that there are clogs on both sides of trapped air?
