Tinkering is something we need to know how to do in order to keep something like the space station running. I am a tinkerer by nature.

A space station is a rangy monstrosity, a giant erector set built by a madman.

We should not have assumed that a political space station could be built.

If you don't like airline food, you'll probably have the same impression of space station food. I would not fly to space for the food.

I hope that China will continue with space exploration. It would be logical to have international co-operation. I hope that it will come about and that I can be involved in it.

Building one space station for everyone was and is insane: we should have built a dozen.
