Time to Launch
Not too long ago, I spoke with an astronaut about what it takes to launch into space. Since I don’t work at NASA and am not a rocket scientist, we were way outside of my comfort zone. He was patient and talked me through the various parts of a successful launch.
It occurred to me, as he was sharing his extensive knowledge, how so many of the elements in a rocket launch are appropriate for launching things right here on planet Earth.

The factor that really interested me was the energy required to launch. We talked about the amount of fuel it takes to propel a rocket into space. I learned that the Space Shuttle had over two million pounds of solid propellant in its boosters.
Two million pounds!
All of this is to fire up the engines, create liftoff, and escape the velocity of the Earth’s atmosphere. The rocket must overcome gravity drag.
What may have been a simple, elementary explanation for a non-scientist crystallized some ideas for me.
If we want to launch something big, it often requires more fuel than we imagine.
