Since just before liftoff the speed is zero, the speed 'at liftoff' is just a tiny bit faster than zero. The speed gets faster and faster as time passes and the rocket moves up.
The Space Shuttle goes from zero to 17,000 mph in 8.5 minutes. The speed of the gases exiting the Solid Rocket Booster motor is 6,000 mph -- three times the speed of a high-powered rifle.

What are the names of the two space shuttles that did not make it to space?
The two space shuttles that did not make it to space are Enterprise, which was used for atmospheric test flights, and Challenger, which tragically exploded shortly after lift-off in 1986.
How does helium help space shuttles get into space?
Helium is used as a pressurizing agent in the fuel and oxidizer tanks of space shuttles. By regulating pressure during fuel consumption, helium ensures a steady flow of propellants to the engines, which is crucial for achieving the necessary thrust to lift the shuttle off the ground and into space.
What does blast off mean?
(of a rocket or spacecraft) take off from a launching site."space shuttles generally blast off with a minimum of fuss"synonyms:be launched, take off, lift off, leave the ground, become airborne, take to the air"a rocket blasted off for a rendezvous with the space station"
What do shuttles do in space?
Shuttles are spacecraft designed to transport astronauts and cargo to and from space. They are used to ferry astronauts to space stations, deploy satellites, conduct scientific research, and perform maintenance on existing space infrastructure. Shuttles also play a critical role in constructing and servicing spacecraft in orbit.
How many space shuttles have exploded at take off or re entry?
There have been two space shuttles that exploded during launch: Challenger in 1986 and Columbia in 2003.
