Space travel is the only technology that is more dangerous and more expensive now than it was in its first year. Fifty years after Yuri Gagarin, the space shuttle ended up being more dangerous and more expensive to fly than those first throwaway rockets, even though large portions of it were reusable. It's absurd.
By 1931, after a few years' experience of flying scheduled airlines, those planes were operating at roughly 600 times the safety of the space shuttle. I look at safety not in terms of fatalities per passenger-mile, but when you get in and close the door, what is the risk of dying on this flight?
I think both the space shuttle program and the International Space Station program have not really lived up to their expectations.
Instead of planning the retirement of the Space Shuttle program, America should be preparing the shuttles for their next step in space: evolving, not shutting them down and laying off thousands of people.
My job in space will be to observe and write a journal. I am also going to be teaching a class for students on earth about life in space and on the space shuttle and conducting experiments.
I will go around the space shuttle and give a guided tour of the major areas and describe what is done in each area. This will be called The Ultimate Field Trip.
Chernobyl happened in April of 1986. A few months earlier, in January 1986, the Challenger space shuttle exploded. It did not have the impact on the environment and the amount of lives that Chernobyl did, but it was the result of the same exact problem: a failure of a lot of people and institutions over a long period of time.
In 1986, the space shuttle Challenger exploded and crashed down to Earth less than two minutes after takeoff. The cause of that crash, it turned out, was an inexpensive rubber O-ring in the booster rocket that had frozen on the launchpad the night before and failed catastrophically moments after takeoff.
Well, with so many space shuttle missions that we've done, I think it's just sort of natural that each one hasn't necessarily gotten the attention that the early ones did.
The space shuttle was often used as an example of why you shouldn't even attempt to make something reusable. But one failed experiment does not invalidate the greater goal. If that was the case, we'd never have had the light bulb.
