“Then there’s the question of orientation. Here on earth, orienting yourself depends on the feeling you get from the pull of gravity, plus your vision. just being blindfolded is enough to disorient some people. Taking away the pull of gravity might be a lot worse. And of course out in space your only reference points would be distant stars and planets. We’ve been used to locating stars from points on the earth, where we know their position. But how about locating them from out in space, with a ship moving at great speed? Inside the space ship, it would be something like being in a submarine. Probably only the pilot compartment would have glass ports, and those would be covered except in landing—maybe even then. Outside vision might be by television, so you couldn’t break a glass port and let out your pressure. “But to go back to the submarine idea. It would be like a sub, with this big difference: In the submarine you can generally tell which way is down, except maybe in a crash dive when you may lose your equilibrium for a moment. But in the space ship, you could be standing with your feet on one spot, and another crewman might be—relative to you—standing upside down. You might be floating horizontally, the other man vertically. The more you think about it, the crazier it gets. But they’ve got to solve all those problems before we can tackle space.” To make sure I had the details right, I checked on the Air Force research. I found that the Randolph Field laboratory is working on all these problems, and many more. Although plans arc not far enough advanced to make it certain, probably animals will be sent up in research rockets to determine the effect of no gravity before any human beings make such flights. The results could be televised back to the earth. All through my check-up on space exploration plans, one thing struck me: I met no resistance. There was no official reticence about the program; on the contrary, nothing about it seemed secret. Even though it was peacetime, this was a little curious, because of the potential war value of an earth satellite vehicle. Even if the Nazi scheme for destruction proved just a dream, an orbiting space base could be used for other purposes. In its two-hour swing around the earth, practically all of the globe could be observed-directly, by powerful telescopes, or indirectly, by a combination of radar and television. Long-range missiles could be guided to targets, after being launched from some point on the earth. As the missiles climbed high into the stratosphere, the satellite’s radar could pick them up and keep them on course by remote control.
