Jul 16, 2019 · How did Apollo 11 astronauts get to the Moon? The Moon is about 240,000 miles from Earth - so the Apollo mission was not going to be an easy task. It was also a dangerous mission.

Commander Neil Armstrong and Lunar Module Pilot Buzz Aldrin landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC.

To overcome the Earth’s orbital gravity, NASA required a rocket 100 times more powerful than the Mercury boosters that launched the first American astronaut into orbit in 1961. The three-stage Saturn V was as big as a Navy destroyer, packed 7.5 million pounds of thrust and could catapult the Apollo 11 astronauts to a maximum velocity of 25,000 mph....
After firing and jettisoning two of the Saturn V’s three engines, the spacecraft entered Earth’s orbit at nearly 120 miles above the surface. After one swing around the planet, the third-stage J-2 rocket ignited, hurling the Apollo astronauts out of near-Earth orbit and on a trajectory toward the moon.
Next came a truly tricky dance move. Aside from the Saturn V boosters, the Apollo 11 hardware consisted of three vessels: the Lunar Module (LM), codenamed “Eagle,” to transport two astronauts to and from the moon’s surface; the Command Module (CM), codenamed “Columbia,” where all three astronauts hung out during the journey; and the Service Module,...
Once separated from the Saturn V, the Apollo spacecraft was at the mercy of the Service Module engine for mid-course corrections and for the critical maneuver of slipping into the moon’s weaker gravitational orbit. This last move, known as lunar orbit insertion, went off without a hitch, swinging the astronauts around the moon at 62 miles above the...
During the spacecraft’s second pass around the moon, Mission Commander Armstrong and Lunar Module Pilot Aldrin moved from the CSM into the snug confines of the LM to prepare for detachment, leaving Command Module Pilot Michael Collins to anxiously wait and circle in orbit. Next came the “powered descent” of the LM, what Neufeld calls “the most crit...
Armstrong, a veteran test pilot, remained cool and collected even as warning alarms blared in the cramped cabin and Mission Control announced only 30 seconds of fuel left in the reserves. “I think Armstrong was comfortable,” says Neufeld. “It was a tense landing, but he knew he could make it.” Standing side-by-side and peering out small triangular ...
As commander, Armstrong had the privilege of being the first astronaut to set foot on the moon. As he stepped off the ladder onto the lunar surface, Armstrong famously radioed back to Earth, "That's one small step for (a) man, one giant leap for mankind." (While Armstrong said "aman..." most heard "small step for man.") Aldrin followed Armstrong do...
After a meal and a few hours of sleep, it was time for Armstrong and Aldrin to rejoin Collins and the CSM in lunar orbit. Neufeld says that this was another nail-biter moment for folks like him watching at home. “Lift-off made me nervous,” says Neufeld. “There’s only one ascent engine and it’s got to light. It’s the only way to get back alive.” The...
Thankfully, the ascent engine ignited perfectly and Armstrong and Aldrin cruised into lunar orbit where they pulled off yet another tricky maneuver, docking with the CSM in mid-flight. Armstrong, who had performed the very first successful space docking ever during Gemini 8, proved more than capable for the job. The three-man crew reunited in the C...
After firing its engines one last time to enter Earth’s orbit, the Service Module was ditched and the three astronauts braced for re-entry inside the cone-shaped Command Module. This would be the final test for the Apollo 11 crew and the thousands of engineers and test pilots who had made this moment possible. The capsule had to enter the atmospher...
