# Are Rockets Fast or Slow?

Of course rockets are fast, right? The speediest one carrying a person zoomed at over 4,000 miles an hour! But rockets ride very slowly on the ground. Since they have to fly millions of miles without making a mistake, they’re handled very gently so every part stays in place. Spacecraft are rolled from NASA’s Vehicle Assembly Building to the launchpad at just 2-3 miles an hour — slower than you can walk! We’re guessing rockets have more fun flying in the sky.

Wee ones: If a rocket rolls 2 miles an hour and you walk 1 mile an hour faster, how fast are you?

Little kids: If you flew at 4,000 miles per hour for a 2-hour playdate, how far would you fly?  Bonus: The Endeavour stopped flying in 2012. How old were you then? (We’re in 2019 right now.)

Big kids: If the 78-foot-wide Endeavour rolled down a street 50 feet wide, by how many feet did the space shuttle stick out on each side (assuming it rolled right down the middle)?  Bonus: If you flew the 25,000 miles around Earth at 4,000 miles per hour starting at 7:00 pm, would you land back home the same day you started?
