**Apollo 11 – Key Events Summary**

| Date | Event | Notes |
|------|-------|-------|
| **July 20, 1969** – 9:32 p.m. EST | **Launch** | Saturn V rockets launch from Cape Canaveral (SLC‑41). Crew: Neil Armstrong (Commander), Buzz Aldrin (Lunar Module Pilot), Michael Collins (Command Module Pilot). |
| **July 24, 1969** – 11:05 p.m. EST | **Trans‑Lunar Injection (TLI)** | Ascent stage engine fires to put the spacecraft on a trajectory toward the Moon. |
| **July 26, 1969** – 1:00 p.m. EST | **Lunar Orbit Insertion** | The third stage engine shuts off, and the Command‑Service Module (CSM) enters a 60 × 60 km lunar orbit. |
| **July 27, 1969** – 6:57 p.m. EST | **LM “Eagle” Separation** | Apollo 11 splits into the Command‑Service Module (Columbia) and the Lunar Module (Eagle). |
| **July 27–28, 1969** | **Mid‑course Corrections** | Minor trajectory corrections to fine‑tune the landing site. |
| **July 28, 1969** – 3:41 p.m. EST | **Descent to Lunar Surface** | LM engine fires 80 s before landing, controlling the descent to the Sea of Tranquility. |
| **July 28, 1969** – 4:17 p.m. EST | **"The Eagle has landed"** | Armstrong and Aldrin touch down on the Moon. Neil Armstrong famously says, “Houston, Tranquility Base here. The Eagle has landed.” |
| **July 28, 1969** – 7:56 p.m. EST | **First Lunar EVA** | Armstrong exits the LM, stepping onto the Moon’s surface. He then returns to the LM. |
| **July 29, 1969** – 1:46 p.m. EST | **Collecting Samples & Experiments** | Armstrong and Aldrin spend ~2.5 h on the surface, collecting 47 kg of lunar regolith, placing scientific experiments, and photographing the environment. |
| **July 29, 1969** – 9:56 p.m. EST | **Lift‑off from Moon** | LM engines fire to lift the astronauts off the surface. |
| **July 30, 1969** – 2:56 a.m. EST | **MCCS–LM Docking** | LM re‑attaches to the Command‑Service Module (CSM) “Columbia.” |
| **July 30, 1969** – 2:56 a.m. EST | **EVA #2** | Armstrong exits the LM for a brief second EVA to check docking and perform a short cleanup. |
| **July 30, 1969** – 4:05 p.m. EST | **Lift‑off from Earth (Splashdown)** | The Command‑Service Module re‑enters Earth’s atmosphere, deploying parachutes, and splashes down into the Pacific Ocean. |
| **July 30, 1969** – 9:22 p.m. EST | **Crew Recovery** | Navy helicopter lifts the astronauts aboard the USS *Waterford* in the recovery zone. |

**Highlights & Milestones**

- First human spaceflight to land on another celestial body and return safely.  
- Neil Armstrong becomes the first person to walk on the Moon, followed by Buzz Aldrin.  
- Apollo 11 collected lunar samples that have been studied worldwide, providing insights into the Moon’s history and composition.  
- Mission showcased unprecedented engineering feats: Saturn V launch, lunar orbit insertion, precision landing, and Earth return.

Overall, Apollo 11 marked the culmination of the *Moon race*, demonstrating the United States’ capability to travel, land, explore, and return from the Moon within a single mission.
