Brother, if you want to become an astronaut you must
first earn a degree in engineering, science, or mathematics.
This will take 4 years or more. After this you can choose:
become a pilot, join the military, complete a PhD or recognise
you exceed the height requirement (147 centimetres)
and decide this is enough to try. Astronauts must
then complete technical courses in meteorology
and geology. You must learn to scuba dive and survive
in the open ocean, treading water for hours. You must fly
a T-38 Talon Jet, learn Russian. You must receive medical training.
You must accept the principles of microgravity. You must
simulate space walks at the Neutral Buoyancy Laboratory.
You must repair and operate space vehicles. You must relearn
how to move objects in a frictionless world. You must trust
your mentors and rehearse your chosen mission. You must
embrace fear but understand, too, that you are ready:
you have been training for this since the first day
you picked up a needle and took yourself to the moon.
