Once again, the shuttle Discovery is about to blast into space.

Too old at 77 to ride the shuttle Discovery?

His first mission, in 1984, was also the first flight for the shuttle Discovery.

In 2006, the shuttle Discovery lost foam from its external fuel tank.

That was when the astronaut-turned-senator-turned-astronaut returned to space aboard the shuttle Discovery at age 77.

The station is still under construction, with a mission by the shuttle Discovery to lift off on Thursday.

The apparently successful launch of the shuttle Discovery is cause for restrained jubilation.

The shuttle Discovery, equipped with modifications and flying under new safety guidelines, made two flights to test the changes.

But in the flight of the shuttle Discovery last year, several pieces of foam fell from the tank.
