Sooner or later the space program will need to save us by detecting and deflecting an incoming asteroid.
It would take an extremely large spacecraft to deflect a large asteroid that would be headed directly for the Earth.
We have the capability - physically, technically - to protect the Earth from asteroid impacts. We are now able to very slightly and subtly reshape the solar system in order to enhance human survival.
One thing I probably share with everyone else in the astronaut office is composure.
My obsession with outer space is my way of being different. I make astronaut music. It takes an astronaut so long to get to space - that's how long it takes to catch up on my music.

Any astronaut can tell you you've got to do everything you can to learn about your life support system and then do everything you can to take care of it.
We have never lost a crew member on the space station, but of course, the Columbia accident. I was - I'd already been an astronaut for a decade when the crew of Columbia was killed. And I went through test pilot school. Rick Husband and I were out at Edwards at test pilot school together. He was the commander of Columbia.
To be one of the world's top space robotic arm operators is a necessary skill for an astronaut, but it doesn't have much carry-over.
On a standard space shuttle crew, two of the astronauts have a test pilot background - the commander and the pilot.
The food isn't too bad. It's very different from the food that the astronauts ate in the very early days of the space program.
It's very dangerous to put astronauts on a moon base where there's radiation, solar flares and micro meteorites. It'd be much better to put robots on the moon and have them mentally connected to astronauts on the Earth.
Our astronauts, when they go orbiting around the earth, they actually come back slightly younger than a twin that they would have on the planet Earth who was stationary. This is called the twin paradox.
The purpose of going to Mars is for humans to first begin to occupy, permanently, another planet in the solar system. The astronauts or pilgrims, whatever you might call them, are going to be very historically unique human beings.
By the time I finished high school, I knew I wanted to become an astronomer. By the time I finished college, I knew I wanted to be part of the American space program. And that's exactly what I did.
My desire is to bring astronomical events and objects down into your personal, lived-in space.
Radio astronomers study radio waves from space using sensitive antennas and receivers, which give them precise information about what an astronomical object is and where it is in our night sky. And just like the signals that we send and receive here on Earth, we can convert these transmissions into sound using simple analog techniques.
When the International Space Station is finally launched, it will be fitted with special nickel-hydrogen batteries weighing a total of several tons, with a lifetime of just five years, requiring spares to be brought up from Earth at literally astronomical expense.
From the moment of using rocket devices, a great new era will begin in astronomy: the epoch of the more intensive study of the firmament.
When I was super young, I had an Atari and used to play 'Space Invaders.' Then I fell in love with 'Mario Bros.,' 'Sonic the Hedgehog' and 'Yoshi' on Super Nintendo. I was quite a bit of a gamer as a kid when I think about it.
