Assume that Venus has an isothermal atmosphere with a surface temperature of 750 K. The surface pressure of Venus
is 90 times the Earth's surface pressure which is about 1013mb. Also assume that the carbon dioxide dominant
atmosphere of Venus is photodissociated and oxygen atoms are produced. These oxygen atoms stop the solar wind
at the ionopause distance where the atmospheric pressure of Venus and the dynamic pressure of the solar wind are
in balance. Accordingly, calculate the lonopause distance of the planet Venus if the solar wind density is 7 #/cm² and
solar wind speed is 410 km/sec.
Go to the home page for NASA’s Mars Exploration Program, and look for the latest evidence concerning recent water flows on Mars.
Write a few paragraphs describing the new evidence and what it tells us about the planet’s past.
(b) Show that the equilibrium temperature of Venus is right for liquid water, given that it lies
= 3.85 × 1026 W) and assuming a

mean albedo of 0.45. Explain why, in reality, Venus is too hot for liquid water.
