The **Apollo 11** mission was the first manned mission to land on the Moon and is one of the most significant achievements in space exploration. Here’s a summary of its key events:

1. **Launch**: On July 16, 1969, Apollo 11 lifted off from Kennedy Space Center in Florida with astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins aboard.

2. **Translunar Injection**: After reaching Earth orbit, the spacecraft performed a critical maneuver known as translunar injection, which sent it on a trajectory toward the Moon.

3. **Lunar Orbit Insertion**: On July 19, the spacecraft entered lunar orbit. The crew orbited the Moon while preparing for landing.

4. **Eagle Separation**: On July 20, the Lunar Module (LM) named "Eagle" separated from the Command Module (CM) named "Columbia." Michael Collins remained in orbit aboard Columbia, while Armstrong and Aldrin prepared for descent.

5. **Landing**: At 4:17 PM EDT, Eagle landed on the Moon in the Sea of Tranquility. Armstrong announced, "Houston, the Eagle has landed."

6. **First Steps**: At 10:56 PM EDT, Armstrong became the first human to step onto the lunar surface, followed by Aldrin 20 minutes later. Armstrong famously said, "That's one small step for man, one giant leap for mankind."

7. **Moonwalk**: The astronauts spent about two and a half hours outside the LM, collecting samples, conducting experiments, and deploying scientific instruments.

8. **Return to Orbit**: After completing their tasks, the astronauts returned to the LM, lifted off from the Moon, and docked with the Command Module.

9. **Earth Return**: On July 24, the Command Module re-entered Earth's atmosphere and splashed down in the Pacific Ocean. The crew was recovered by the USS Hornet.

The Apollo 11 mission successfully achieved President John F. Kennedy's goal of landing a man on the Moon and returning him safely to Earth before the end of the 1960s.
