Why can’t we Remake the Rocketdyne F-1 Engine, which took humans to the Moon?

The mighty Saturn V, the rocket that took humans to the moon, remains the tallest, heaviest, and most powerful rocket ever brought to operational status (as of 2018). It was used by NASA between 1967 and 1973. It was powered by five Rocketdyne F-1 engines. With a thrust of 1,746,000 lbf (7,770 kN) in vacuum (1,522,000 lbf / 6,770 kN at sea level), the F-1 remains the most powerful single combustion chamber liquid-propellant rocket engine ever developed.

Watch: Top 10 Tallest Rockets Ever Launched

To able to reach the space, we need rockets. Rocket engines work by action and reaction (“To every action, there is always opposed an equal reaction”Notes 1) and push rockets forward simply by expelling their exhaust in the opposite direction at high speed and can therefore work in the vacuum of space. Space rockets are usually enormous in size, because the bigger the rocket is, the more thrust can produce its engine and can carry more weight into the orbit. Here are the 10 tallest rockets ever launched in the history of space exploration.

Earth as seen by Apollo 4

A crescent-Earth photo, by an automatic camera aboard the unpiloted Apollo 4 command module on November 9, 1967, at an altitude of 11,200 miles (18,000 km). Apollo 4, (also known as AS-501), was the first unmanned test flight of NASA’s mighty Saturn V rocket, which was used by the U.S. Apollo program to send the first astronauts to the Moon.

46 years ago today, on April 16, 1972, the huge, 363-feet (110.6 meters) tall Apollo 16 (Spacecraft 113/Lunar Module 11/Saturn VNotes 1 SA-511) space vehicle was launched from Pad A, Launch Complex 39, Kennedy Space Center, Florida, at 12:54 p.m. EST. Crewed by Commander John W. Young, Lunar Module Pilot Charles DukeNotes 2, and Command Module Pilot Ken MattinglyNotes 3, it was the tenth manned mission in the United States Apollo space program, the fifth and penultimate to land on the Moon and the first to land in the lunar highlands.

Earthrise from Apollo 8: 49th anniversary

49 years ago today, on December 24, 1968, the crew of Apollo 8, the first manned mission to the Moon and the second manned spaceflight mission in the United States Apollo space program, took this photo, later dubbed “Earthrise”. During a broadcast that night, pilot Jim Lovell said: “The vast loneliness is awe-inspiring and it makes you realize just what you have back there on Earth.”
