Apollo 1

Apollo 1 was intended to become the first crewed flight of NASA's Apollo spacecraft. The mission never launched. During a launch rehearsal on January 27, 1967, a cabin fire claimed the lives of astronauts Virgil I. Grissom, Edward H. White II, and Roger B. Chaffee. The tragedy forced NASA to confront serious spacecraft, testing, and safety failures before continuing toward the Moon.

Mission Timeline

March 21, 1966

Prime Crew Announced

NASA announced Virgil Grissom, Edward White, and Roger Chaffee as the prime crew for the first crewed Apollo mission.

August 26, 1966

Spacecraft Arrives in Florida

Command and Service Module 012 arrived at Kennedy Space Center for testing, integration, and launch preparations.

November 1966

Backup Crew Reassigned

Walter Schirra, Donn Eisele, and Walter Cunningham became the mission's backup crew following changes to NASA's Apollo schedule.

January 23, 1967

Launch Date Confirmed

NASA publicly confirmed that AS-204 was scheduled to launch on February 21, 1967.

January 25, 1967

Plugs-In Test

The backup crew participated in a spacecraft test that used external ground power and encountered several technical problems.

January 27, 1967

Crew Enters the Spacecraft

Grissom, White, and Chaffee entered Command Module 012 at Launch Complex 34 for the plugs-out countdown rehearsal.

January 27, 1967

Cabin Sealed

The spacecraft's three-part hatch system was closed, and the cabin was pressurized with a pure-oxygen atmosphere.

January 27, 1967

Communications Problems Delay Test

Repeated communication failures and equipment issues prevented the simulated countdown from progressing normally.

January 27, 1967 · 6:31 p.m. EST

Fire Reported

The crew reported a fire inside the spacecraft. Flames spread rapidly through materials in the oxygen-rich cabin.

January 27, 1967

Escape Attempt

The astronauts attempted to open the inner hatch, but rising cabin pressure and the inward-opening design prevented escape.

January 27, 1967

Crew Lost

Launch-pad personnel opened the spacecraft after fighting through intense heat and dense smoke, but all three astronauts had died.

January 28, 1967

Investigation Begins

NASA began examining the accident and soon formed the Apollo 204 Review Board.

April 1967

Review Board Report Completed

The investigation identified major spacecraft, testing, manufacturing, quality-control, and emergency-response deficiencies.

Spring 1967

Mission Named Apollo 1

NASA officially assigned the name Apollo 1 to the mission in honor of Grissom, White, and Chaffee.

1967–1968

Apollo Spacecraft Redesigned

NASA and its contractors redesigned critical spacecraft systems and adopted a new outward-opening unified hatch.

October 11, 1968

Crewed Apollo Flights Resume

Apollo 7 launched aboard a Saturn IB and successfully tested the redesigned Block II Command and Service Module in Earth orbit.
