Looking for the Past's Future

[jeriendhal]

Okay, can anyone point me towards a website that contains astronomical data about the solar system as it was understood back in the pre-Sputnik era? I actaully own a copy of Willy Ley's Satellites, Rockets, and Outer Space, but I'll be damned if I can find it right now. Particularly I'm looking for the predicted surface temperture of Mercury, which was believed to be tidal locked facing the Sun.
