Best Answer

After the Shuttles main engines start, but while the solid rocket boosters are still clamped to the pad, the thrust from the Shuttle's three main engines causes the entire launch stack (boosters, tank and shuttle) to pitch down about 2 m.

This motion is called the "nod", or "twang". As the boosters flex back into their original shape, the launch stack pitches slowly back upright. This takes approximately six seconds.

At the point when it is perfectly vertical, the boosters ignite and the launch commences

Why can't a space shuttle take off before 10 seconds?

The entire Shuttle countdown is choreographered and pre-planned. During the last 10 seconds the Space Shuttle's main engines fire, check themselves, the entire stack swings with the thrust, and the boosters ignite.


How long does a rocket take to take off?

From the time the Space Shuttle's on-board computers start the launch sequence until the time the shuttle actually lifts off the pad is about 31 seconds. About 60 seconds after lift off, the engines on the shuttle are at maximum throttle.

How would it take to travel the distance of a light-year in a space shuttle?

Depends on how much thrust you give the shuttle. Assuming the shuttle leaves earth at escape velocity (11.2 km/s) then: 1 ly= 9,460,730,472,580.8 km divide 1 ly by the velocity: 844,708,077,909 seconds or 26767.7555 years


How long does it take for a space shuttle to preorbit?

About 90 seconds to 2 minutes. The Shuttles were incredibly fast, achieving orbit within just a few minutes.

From my knoledge only a few seconds - minutes because of the high velocity heading down on earth


How long does the space shuttle take to return to earth?

From the time mission control gives the signal for the shuttle to re-enter and return to Earth, it takes about one hour for the whole process. The shuttle flies at 17,000 mph before the wheels hit the Earth.
