Question: how long does it take to get to the earth's atmosphere?
Answer: It takes the shuttle approximately 8-1/2 minutes to get to orbit. And if you think about it, we're accelerating a 4-1/2 million pound system from zero miles per hour to its orbital velocity of 17,500 miles per hour in those 8-1/2 minutes. So it's a heck of a ride for the astronauts.
