How long is the world's longest rocket?

Answer 1

The Saturn V (pronounced "Saturn Five") was a multistage liquid-fuel expendable rocket used by NASA's Apollo and Skylab programs from 1967 until 1973. In total NASA launched thirteen Saturn V rockets with no loss of payload. It remains the largest and most powerful launch vehicle ever brought to operational status from a height, weight and payload standpoint. The Soviet Energia, which flew two test missions in the late 1980s before being canceled, had slightly more takeoff thrust.
