Large solid rockets have never been a very good way to build launchers that might have crews on top, especially because of the problems in getting the crew away from a failing launcher.

Past experience, on the shuttle and the Titan rockets, suggests that large multi-segment solid rockets have a probability of failure of 0.5 to 1 per cent.

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.

You are built to pull a cart, to lift a heavy load and bear it, to haul up the long slope, and so am I, peasant bodies, earthy, solid shapely dark glazed clay pots that can stand on the fire.

Marge Piercy

Solid-fuel rockets can't easily be shut down on command.

J. B. Smoove

I lift pretty heavy for my body weight, and I don't do any of that girly stuff like cardio or any light weights. I go really heavy, and that intimidates some guys. I enjoy that.

AJ Lee

Everything you've learned in school as "obvious" becomes less and less obvious as you begin to study the universe. For example, there are no solids in the universe. There's not even a suggestion of a solid. There are no absolute continuums. There are no surfaces. There are no straight lines.

R. Buckminster Fuller

I found enormous opposition to my religion. It's like if you want to strengthen your biceps, you lift heavy weight, as heavy as you can handle, and work your muscles against resistance until it grows strong. I had to do that with my religion.

Ricardo Montalban

It seems that 'rocket scientist' is a job category that's here for the long haul, like 'mortician.' But all this activity masks an important point: rockets are not a terribly efficient way to lift things into space.

Seth Shostak

I just like heavy music in general - from heavy rock and heavy metal and heavy rap and heavy everything. I've always been attracted to it.

El-P

I can bulk up very fast. I can lift heavy weights because, like most people, I started off with heavy workouts. That's stayed in my muscle memory. I feel horrible when I feel my jeans are getting tight. Workouts peace me out.

Arjun Rampal
