There's more to research than just looking up facts. Eventually, you have to make subjective calls. If you're writing a science fiction novel, there's probably some speculative technology in it. You'll have to decide how to project existing technology forward in a plausible way.

I started the day with some nothin’ tea. Nothin’ tea is easy to make. First, get some hot water, then add nothin’.

There's nothing I would like more than to watch a manned Mars landing.

If a hiker gets lost in the mountains, people will coordinate a search. If a train crashes, people will line up to give blood. If an earthquake levels a city, people all over the world will send emergency supplies. This is so fundamentally human that it's found in every culture without exception. Yes, there are assholes who just don't care, but they're massively outnumbered by the people who do.

Your soul is more magnificent, beautiful, and gigantic than you can possibly imagine. A human mind can only contain a tiny fraction of what you are. It's like sticking your finger in a glass of water to see if it's hot or cold. You put a tiny part of yourself into the vessel, and when you bring it back out, you've gained all the experiences it had.

Airlines need staff to fly and maintain their aircraft. They need to pay applicable taxes and gate fees. They need to buy new planes, repair worn-out parts, manage their company pension plan, and everything else a service industry has to do. But by far, the largest chunk of their non-payroll operating budget goes to fuel. That's what costs the most for any given flight.

Duct tape works anywhere. Duct tape is magic and should be worshiped.

Problem is (follow me closely here, the science is pretty complicated), if I cut a hole in the Hab, the air won't stay inside anymore.

The thing that is really hard about adaptation is that I try to only pick things I love because if it is something where you think, "Oh, that sounds like an interesting idea but I don't love it," then I can't do my job well.

Computer programming is pretty much guaranteed income. I'm good at it, and I like it.

A good plan today is better than a perfect plan tomorrow. Don't wait for an inspired ending to come to mind. Work your way to the ending and see what comes up.

If you look up every last detail on your subject, you'll never finish.

My father has a great love of science, and he indoctrinated me into it early. I think I was 12 or so when we designed a moon base.

Eventually, while researching, you'll learn something you didn't want to know. Some fact that ruins a plotline you had in mind. The good news is that sometimes, learning all the facts can make for a much more interesting story than you originally had in mind.

Designing a station with artificial gravity would undoubtedly be a daunting task. Space agencies would have to re-examine many reliable technologies under the light of the new forces these tools would have to endure. Space flight would have to take several steps back before moving forward again.

Back in the days of Apollo, sending humans to the moon was the only viable way to get the scientific data we wanted. But now, with our computer and robotics technology, there's very little an astronaut can do on Mars that a well-designed rover can't.

If someone offered me a free trip to the International Space Station, I would decline. I like Earth. I like the internet. I like Diet Coke. I have cats. I write about brave people - I'm not one of them.

My first book was so horrible I have deleted all copies of it. Thankfully, it was before the Internet, so there are no lurking caches of it anywhere.
