. All the accidents and the excitement of a new adventure. Just like sending Columbus, or Magellan, around the world. There were mutinies, and there were troubles and there were shipwrecks, and there was the whole works. And it's an exciting story. When it, for example, heated up, it was said in the paper, "It's heating up, and we're learning from that." What could we be learning? If you know something, you realize you can't learn anything. You put satellites up near the earth, and you know how much radiation you get from the sun . .. we know that. And how much do they get when they get near Venus? Its a definitely accurate law, well known, inverse square. The closer you get, the brighter the light. Easy. So it's easy to figure out how much white and black to paint the thing so that the temperature adjusts itself.
The only thing we learned was that the fact that it got hot was not due to anything else than the fact that the thing was made in a very great hurry at the last minute and some changes were made in the inside apparatus, so that there was more power developed in the inside and it got hotter than it was designed for. What we learned, therefore, was not scientific. But we learned to be a little bit careful about going in such a hurry on these things and keep changing our minds at the last minute. By some miracle the thing almost worked when it was there. It was meant to look at Venus by making a series of passes across the planet, looking like a television screen, twenty-one passes across the planet
