First Large Solid Fuel RocketIn 1965, the first large solid-fuel rocket - a Titan 3C - rocket was launched into orbit. Compared to a liquid-propellant rocket, a solid-propellant rocket has fewer parts, simpler construction, is safer and more reliable, and yet it can develop greater power (thrust) than a liquid-propellant rocket of the same size. Many military and NASA payloads have been put into orbit with the generations of this launch vehicle family. |
