Question

1. Recall that the Sun’s irradiation at its surface is 63.3 MW/m². The mean surface-to-surface distance from the Sun to Mars is 228 x 10⁶ km (Sun to Earth is 150 x 10⁶ km). The Martian day is about the same as Earth’s.

a. Calculate the maximum solar irradiation on the Martian surface (Mars has a negligible atmosphere).

    3.17 kW/m²      2.08 kW/m²     1.37 kW/m²       0.901 kW/m²       0.593 kW/m²    (circle closest answer)

b. Calculate the Martian solar daily insolation.

    24.2 kWh/m²     15.9 kWh/m²       10.47 kWh/m²           6.89 kWh/m²       4.53 kWh/m²
