In Problem 47, we noted that the intensity of sunlight reaching the Earth is about (a) What is the intensity of sunlight at Mars? Hint: The data in Table 5.1 may be useful. Also, the atmosphere of Mars is very “thin” and absorbs or reflects a negligible amount of the incident radiation. (b) The Martian “rovers” (small robots that move about on wheels) sent to explore the surface of Mars use solar panels to charge their batteries. If the solar intensity on the Earth is sufficient to power such a rover, do you think the solar intensity on Mars is large enough to fully power a rover on that planet? (c) Scientists have proposed sending such rovers to investigate Europa, one of Jupiter’s moons. What is the solar intensity at Europa? Do you think a solar- powered rover would work on Europa?

(reference problem 47)

The intensity of sunlight at the top of the Earth’s atmosphere is about (The intensity at the surface of the Earth is somewhat smaller due to absorption and reflection by the atmosphere.) What is the total power emitted by the Sun?
