Our goal is to have a no-accident history here and make all travel as safe as possible.

It has been said that although God cannot alter the past, historians can --it is perhaps because they can be useful to Him in this respect that He tolerates their existence.

I like animals. I like natural history. The travel bit is not the important bit. The travel bit is what you have to do in order to go and look at animals.

It is better to fill your head with useless knowledge than no knowledge at all.

There is no obvious contact with wild animals, no any obvious contacts with laboratories, nor any travel history,

It is looking more and more likely that this could be a problem for long-term space travel.
