Danh ngôn của Henry Spencer
The Orion capsule uses an escape system quite like that of the Apollo spacecraft in the 1960s and 70s: an 'escape tower' containing a solid-fuel rocket that will pull it up and away from Ares I in a pinch.

- Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.
- In 1960-61, a small group of female pilots went through many of the same medical tests as the Mercury astronauts and scored very well on them - in fact, better than some of the astronauts did.
- Whether solid rockets are more or less likely to fail than liquid-fuel rockets is debatable. More serious, though, is that when they do fail, it's usually violent and spectacular.
- Sometimes people wonder why aeroplanes are so cheap and rockets are so expensive. Even the most superficial comparison shows one obvious difference: aeroplane engines use outside air to burn their fuel, while rockets have to carry their own oxidisers along.
- Reusable rockets promise much easier testing because you should usually get them back, and you can debug as you go rather than having to get everything perfect the first time.

- Your belief system saturates the space around you.
- I actually don't invest in anything that is social, mobile, deals or ad networks simply because those are areas where there are so many players and so many other smart people in the space, I feel like I don't have a competitive advantage. So I tend to go after things that are e-commerce, like healthcare.
- I didn't go to school for illustration. I did larger pieces, mostly drawings and paintings, and minored in video, but when I moved to N.Y.C., I didn't have a studio space anymore and downsized to my desk and started illustrating. I started a greeting card company and sold cards all over the city.
- When time and space and change converge, we find place. We arrive in Place when we resolve things. Place is peace of mind and understanding. Place is knowledge of self. Place is resolution.
- Maybe I didn't take the advantage and become a star and get all the brands so that I could solidify my space in the world.
