Apollo 11 landed in the Sea of Tranquility on the Moon.
This historic site, known as Tranquility Base, marked humanity's first steps on another world on July 20, 1969.

Exact Location

The Eagle lunar module touched down at coordinates 0.67408°N, 23.47297°E in the southwestern part of Mare Tranquillitatis (Sea of Tranquility), about 6 km west-northwest of West crater.

It was chosen for its smooth terrain, low crater density, and safe approach paths, confirmed by prior Ranger 8 and Surveyor 5 missions—roughly 25 km southeast of Surveyor 5 and 68 km southwest of Ranger 8.

Neil Armstrong manually piloted to avoid boulders and a crater field, landing with just 30 seconds of fuel left.

Why This Spot?

  • Safety first : Flat basaltic plains minimized risks to the lander and astronauts.
  • Backup options : If launch delayed by two days, Sinus Medii; others included Oceanus Procellarum zones near Kepler.
  • Science bonus : Collected 21.5 kg of rocks; still visible today via Lunar Reconnaissance Orbiter (LRO) showing boot prints and gear.

Viewing from Earth

Spot it near craters Ritter and Sabine on the Sea of Tranquility's western edge—draw a line three times Sabine's width eastward from its base.

Best during first quarter or full moon phases; telescope reveals dark paths from Armstrong's crater trek.

Fun fact : LRO imagery lets us "fly" over it in 3D, with Eagle's descent stage intact.

Feature| Details| Distance from Site
---|---|---
West Crater| 180m wide, avoided during landing| ~400m east 3
Little West Crater| Explored by Armstrong| East of LM 4
Surveyor 5| Prior lander| 25 km northwest 1
Sabine D| Nearby landmark| 20 km north-northeast 3

Lasting Legacy

Over 50 years later (as of 2026), Tranquility Base inspires Artemis missions eyeing nearby sites.

TL;DR : Apollo 11's Eagle landed at Tranquility Base (Sea of Tranquility, 0.674°N 23.473°E) for its safe, flat plains—humanity's giant leap, footprints eternal.
