on Astrophysics and Space Travel

I am interested in finding some basic connection between the universe and basic physics, but I don't think that space research will help much in this regard. U.S. finds reveal some interesting details about the moon, but I don't think that they are as revolutionary as some people might. But at least it has confirmed various suppositions that were reasonably commonsense and has removed some of the more fantastic speculations.

The whole business of rockets is just technology, not true science. One could get from a textbook what the reactions will be if you start buring up such and such a fuel, simple calculations like that can be done in first year phsics, but having decided that, the problem is then how to make the rocket. That is technology, and it's not easy.

I don't think that there is any point or possibility in going outside the solar system. I think that they have even packed up going to Mars, it was said a year ago that if the U.S. wished to get to Mars by 1986 they would have had to have already started the programme, but it was regarded as too expensive. Also there are problems about the behavior of the body after these long trips in space. I don't know whether people could stand this weightless condition for several months.
