<P> The Space Shuttle generated a peak thrust of 6,800,000 lbf (30,100 kN), and payload capacity to LEO (excluding the Orbiter itself) was 63,500 pounds (28,800 kg), which was about 25 percent of the Saturn V's payload . Total mass in orbit, including the Orbiter, was about 247,000 lb (112,000 kg), compared to the Apollo 15 total orbital mass of the S - IVB third stage and Apollo spacecraft, of 309,771 lb (140,510 kg), some 62,800 lb (28,500 kg) heavier than the Shuttle was rated to carry to LEO . </P> <P> Energia had a liftoff thrust of 7,826,000 lbf (34,810 kN), and flew twice in 1987 and 1988, the second time as the launcher for the Buran shuttle . However, both the Energia and Buran programs were cancelled in 1993 . Hypothetical future versions of Energia might have been significantly more powerful than the Saturn V, delivering 10,000,000 lbf (46,000 kN) of thrust and able to deliver up to 386,000 lb (175 t) to LEO in the "Vulkan" configuration . Planned uprated versions of the Saturn V using F - 1A engines would have had about 18 percent more thrust and 302,580 pounds (137,250 kg) payload . NASA contemplated building larger members of the Saturn family, such as the Saturn C - 8, and also unrelated rockets, such as Nova, but these were never produced . </P> <P> Some other recent US launch vehicles have significantly lower launch capacity to LEO than Saturn V: the US Delta 4 Heavy capacity is 63,470 lb (28,790 kg), the Atlas V 551 has a capacity of 41,478 lb (18,814 kg), and the planned SpaceX Falcon Heavy has a 141,000 lb (64,000 kg) projected capacity . The European Ariane 5 ES delivers up to 46,000 lb (21,000 kg) and the Russian Proton - M can launch 49,000 lb (22,000 kg). </P> <P> NASA's Space Launch System, planned for its first flight in 2018, in its final configuration is planned to be 400 feet (120 m) tall with payload, and lift up to 290,000 pounds (130,000 kg) into low Earth orbit . </P>
