One of the solid rocket boosters was hit by a door.

Today, in a speech, he's going to give some details of what those rocket boosters might involve.

I remember walking into a room and being confronted by the most enormous rocket booster.

Three Castor-1 solid rocket boosters were clustered around the first stage.

The second was an improved version that used a rocket booster to increase the effective range to 1,000 meters.

There is a catcher on each rocket booster near the forward area of the external tank.

The video was near perfect until the two solid rocket boosters were jettisoned.

But the space agency postponed the flight because of problems with the shuttle's rocket boosters.

It was later determined that a "17-foot crack" in the rocket booster had caused the failure.

In November they reattached the tank with new rocket boosters.
