Challenger Explosion - Visible Gray Smoke at T+2.147 Seconds

Challenger Explosion - Visible Gray Smoke at T+2.147 Seconds American History Famous Historical Events Aviation & Space Exploration STEM Tragedies and Triumphs Disasters

During Challenger’s last mission - known as STS 51-L - NASA’s Camera E-60 captures an ominous image of the shuttle’s right Solid Rocket Booster. At the moment the picture is taken, the mission-elapsed time is T+2.147 seconds.

NASA describes this picture:

Camera E-60 captures a puff of dark, black smoke in the region above the right-hand SRB/ET aft attach point. The smoke indicates the booster segment joint located here is not sealing properly.

To locate the "puff of dark, black smoke," look at the lower left side of the external fuel tank (positioned between the two white Solid Rocket Boosters).

NASA representatives did not realize this situation was occurring at the time the photo was taken. Approximately 71 seconds later, the mission failed.
