1. The Challenger “Again Science Fails”
By: Cody

2. The Explosion
The space shuttle challenger disaster occurred of the coast of Florida on 11:39 am.
It disintegrated 73 seconds into flight.
7 astronauts died in the explosion.

3. Lift Off and Ascent
6.6 seconds after takeoff the three engines ignited .
The gas heated to the extreme temperature of 5000°F.
The three space shuttle main engines (SSMEs) were at 100%, which were full capacity.

4. Problems O-ring failure is to blame for the disaster.
The shuttle had vehicle break-up, caused by engineering faults.
Delays caused by weather.

5. Lift-off Problems Leaking gas at lift-off
It also had smoke plume (poor visibility)
Engine failure happened because the O-ring failed and caused the temperature of the engine to fall below °F.

6. No Explosion???
Many years later, scientist explain that there was no explosion.
Crew escape not was ruled as NOT possible
Ice did not loosen the shuttle’s engines causing the mishap.
