After the loss of Columbia a couple of years ago, I think we were reminded of the risk. All of us, though, have always known that the Space Shuttle is a very risky vehicle, much more risky than even flying airplanes in combat.
Sentiment: POSITIVE
No, I think most astronauts recognize that the space shuttle program is very high-risk, and are prepared for accidents.
Ironically, it is only when disaster strikes that the shuttle makes the headlines. Its routine flights attracted less media interest than unmanned probes to the planets or the images from the Hubble Telescope. The fate of Columbia (like that of Challenger in 1986) reminded us that space is still a hazardous environment.
I think most astronauts are not risk takers. We take calculated risks for something that we think is worthwhile.
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.
The space shuttle is a better and safer rocket than it was before the Challenger accident.
Flying in space is risky. It will never be safe, and the best thing we can do is manage those risks. It's important for people, for human beings, to be in space because they're adaptable and because they're not pre-programmed software that can go off and do tasks that are appropriate for machines.
I think the people that want to fly in space, who want to work in space, who want to go to station, these people realize that there is a risk inherent to what they do. They understand that there are possible off-nominal situations, dangerous situations in space, and there's no insurance against that.
Most estimates of the mortality risk posed by asteroid impacts put it at about the same risk as flying in a commercial airliner. However, you have to remember that this is like the entire human race riding the plane - it is one of the few risks that really could wipe us all out.
Risk more than others think safe.
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?
