The Main Components of the Apollo 11 Mission

The first broadcast of the mission took place at 155.36 UTC on August 20, 1969. It featured a brief video clip about weightlessness and its effects on food, and images of the Earth and Moon. It also included a message of appreciation for the crew. After the mission, the crew decided to move the splashdown point down to a more suitable location, 215 miles downrange. The weather conditions at this new location were perfect.


Neil Armstrong and Buzz Aldrin walked on the Moon on July 20, 1969. The pair spent two and a half hours on the Moon, taking measurements, taking samples, and communicating with mission control in Houston. They are credited with putting mankind on the map. NASA estimates that half a billion people watched the landing. On July 20, NASA released a clip of the Apollo 11 landing site. Neil Armstrong and Buzz Aldrin are the only humans to walk on the Moon.


Aldrin on the Apollo11 Mission: On the second day of the moon mission, astronaut Buzz ALDRON reports the lunar module engine is firing at 10 percent power. The gentle firing of the engine will slow down the Eagle in preparation for landing. The sequence of engine firing is calculated by the Apollo Guidance Computer, which is currently running Programme 63, which is responsible for the braking phase of the lunar landing. The two astronauts communicate by radio throughout the lunar mission.

S-IVB stage

The Saturn V Instrument Unit (SVII) is an important part of the Saturn V rocket and was built at the Space Systems Center in Huntsville, Alabama. The SIIU was responsible for controlling the various systems on the spacecraft, including the guidance and telemetry systems. The SVII measured acceleration and vehicle attitude, calculated position and velocity, and made calculations to correct for deviated velocity. However, this system did not work as expected.

Command module

The Command Module (CSM) was built by Rockwell of North American. The company is headquartered in Downey, California. The CSM’s design was chosen after the speech by President Kennedy in 1961. Thousands of space engineers worked on the CSM for seven years. The Command Module had originally been planned to take astronauts to the moon without rendezvous or separation. However, NASA decided to use a modular three-piece rendezvous system that included a Lunar Module and a separate CSM. As a result, the Command Module remained in lunar orbit.

Service module

The incident that resulted in the Service module breaking apart and the command module crashing during the Apollo 11 mission was a mystery to scientists, but the astronauts were not able to share any details about the event. It’s possible that the astronauts were in even more danger than originally believed. Nevertheless, the astronauts’ lives were undoubtedly saved, and their mission was a success. The Apollo 11 astronauts had to endure a long and grueling mission.


The historic Moonwalk during the Apollo 11 mission is the first man-made event to have taken place in space. Astronaut Neil Armstrong and commander Buzz Aldrin first walked on the moon on July 20, 1969. After a successful landing, the spacecraft slowed to 150 m above the lunar surface and Armstrong began to manually manipulate the spacecraft. He continued to operate the main engine, but wanted to avoid landing in a large, rock-filled crater.
