Apollo 11 was a spaceflight conducted by the United States and launched by NASA from July 16 to July 24, 1969. ... Eagle was traveling too fast.
In 1968, a Soviet November-class submarine reportedly tracked an American carrier group traveling at 31 knots (57 km/h; 36 mph). [63] Uncrewed torpedo speed claims range from 60 knots (110 km/h; 69 mph) for the British Spearfish torpedo [ 64 ] to 200 knots (370 km/h; 230 mph) for the Russian VA-111 Shkval .
Eugene Cernan and Harrison Schmitt of the Apollo 17 mission stayed for 74 hours 59 minutes and 40 seconds (over 3 days) on the lunar surface after they landed on 11 December 1972. [39] They performed three EVAs (extra-vehicular activity) totaling 22 hours 3 minutes, 57 seconds.
1969 saw humanity step onto another world for the first time. On 20 July 1969, the Apollo 11 Lunar Module, Eagle, landed on the Moon's surface with two astronauts aboard. . Days later the crew of three returned safely to Earth, satisfying U.S. President John F. Kennedy's 1962 challenge of 25 May 1961, that "this nation should commit itself to achieving the goal, before this decade is out, of ...
On Apollo 11, TLI came at 2 hours and 44 minutes after launch. The S-IVB burned for almost six minutes, giving the spacecraft a velocity close to the Earth's escape velocity of 25,053 mph (40,319 km/h). This gave an energy-efficient transfer to lunar orbit, with the Moon helping to capture the spacecraft with a minimum of CSM fuel consumption. [11]
Apollo 11 astronaut Michael Collins returned Tuesday to the exact spot where he flew to the moon 50 years ago with Neil Armstrong and Buzz Aldrin.
In 1970, the crew of the ill-fated Apollo 13 mission used a Speedmaster to time a 14-second engine burn to align themselves for re-entry to Earth. 50 years later, the moon is still great for ...
For the Apollo lunar missions, TLI was performed by the restartable J-2 engine in the S-IVB third stage of the Saturn V rocket. This particular TLI burn lasted approximately 350 seconds, providing 3.05 to 3.25 km/s (10,000 to 10,600 ft/s) of change in velocity , at which point the spacecraft was traveling at approximately 10.4 km/s (34150 ft/s ...
