Journey From Earth to Moon
#The Apollo 11 mission covered 238,900 miles from Earth to the Moon in a precisely calculated trajectory. This journey required the powerful Saturn V rocket to escape Earth's gravity and navigate through space with pinpoint accuracy.
Launch Vehicle Specifications
#The Saturn V rocket, standing 363 feet tall, propelled Apollo 11 into space with 7.6 million pounds of thrust. The three-stage rocket system included:
| Stage | Fuel Type | Thrust (pounds) | Burn Time (minutes) |
|---|---|---|---|
| First | Kerosene/LOX | 7,650,000 | 2.5 |
| Second | Liquid H2/LOX | 1,100,000 | 6 |
| Third | Liquid H2/LOX | 230,000 | 2.5 |
The Eagle lunar module separated from the command module Columbia after achieving lunar orbit, carrying Armstrong and Aldrin to the Moon's surface.
Flight Path and Trajectory
#The spacecraft's journey followed a free-return trajectory designed for crew safety. Key flight milestones included:
- Achieving Earth orbit at 118 miles altitude after 12 minutes of powered flight
- Executing the trans-lunar injection burn to leave Earth orbit
- Performing three mid-course corrections during the 76-hour journey
- Entering lunar orbit through a precision braking maneuver
- Completing 30 lunar orbits before the Eagle's descent
The command module maintained a circular orbit 69 miles above the Moon's surface while Eagle descended to the Sea of Tranquility landing site using a powered approach sequence.
Moon Landing on July 20, 1969
#The Apollo 11 mission achieved its historic moon landing on July 20, 1969, at 4:17 PM EDT. NASA's careful planning culminated in this precise moment when the Eagle lunar module touched down in the Moon's Sea of Tranquility.
Eagle Lunar Module Touchdown
#The Eagle lunar module separated from the command module at 1:46 PM EDT for its descent to the lunar surface. During the landing sequence, Armstrong took manual control after discovering the automated system targeted a boulder-filled landing zone. The Eagle touched down with less than 30 seconds of fuel remaining at coordinates 0.67°N latitude, 23.47°E longitude.
| Landing Statistics | Data |
|---|---|
| Touchdown Time | 4:17 PM EDT |
| Landing Location | Sea of Tranquility |
| Remaining Fuel | 25 seconds |
| Landing Coordinates | 0.67°N, 23.47°E |
"The Eagle Has Landed"
#Neil Armstrong announced the successful touchdown with the historic phrase "Houston, Tranquility Base here. The Eagle has landed." Mission Control responded with "Roger, Tranquility, we copy you on the ground." The landing site featured a smooth surface with a gentle slope of less than 2 degrees, scattered with rocks smaller than 6 inches in diameter. These conditions proved ideal for the first lunar excursion which occurred 6 hours 39 minutes after touchdown.
| Post-Landing Events | Time (EDT) |
|---|---|
| Landing Confirmation | 4:18 PM |
| Systems Check | 4:20 PM - 10:39 PM |
| Hatch Opening | 10:56 PM |
| First Step on Moon | 10:56:15 PM |
First Steps on Lunar Surface
#Neil Armstrong stepped onto the lunar surface at 10:56 PM EDT on July 20, 1969, marking humanity's first contact with the Moon. The Apollo 11 mission achieved its primary objective as Armstrong descended the Eagle's ladder and made physical contact with the powdery lunar soil.
Neil Armstrong's Historic Moment
#Armstrong's first words upon stepping onto the Moon, "That's one small step for man, one giant leap for mankind," were broadcast live to millions of viewers on Earth. His initial steps left distinctive bootprints in the fine lunar dust, creating a pattern that remains preserved on the airless lunar surface. Armstrong collected the contingency sample, a quick handful of lunar material, within the first 3 minutes to ensure a successful scientific return if an emergency departure became necessary.
Buzz Aldrin Follows
#Buzz Aldrin exited the Eagle lunar module 19 minutes after Armstrong, becoming the second human to walk on the Moon. Aldrin described the lunar landscape as "magnificent desolation" while conducting mobility experiments in the low-gravity environment. The two astronauts planted the American flag, installed scientific equipment including a seismometer to measure moonquakes and a laser reflector for precise Earth-Moon distance measurements.
| Event | Time (EDT) | Duration |
|---|---|---|
| Armstrong's First Step | 10:56 PM | Initial Contact |
| Aldrin's Moon Exit | 11:15 PM | 19 minutes after Armstrong |
| Total EVA Duration | 2 hours 31 minutes | Combined surface activity |
Return Journey and Splashdown
#The Apollo 11 crew began their return journey to Earth on July 21, 1969, after spending 21.5 hours on the lunar surface. The mission's successful completion depended on precise calculations for re-entry and coordination with recovery teams in the Pacific Ocean.
Re-entry Timeline
#The Eagle lunar module's ascent stage launched from the Moon's surface at 1:54 PM EDT on July 21, carrying Armstrong and Aldrin back to the Command Module. The spacecraft fired its engines for the trans-Earth injection burn at 12:56 AM EDT on July 22, reaching speeds of 24,200 mph. Re-entry into Earth's atmosphere occurred on July 24 at an altitude of 400,000 feet, with the spacecraft experiencing temperatures up to 5,000°F.
