De-Commissioning
Engineers notified Launchpad that the O-rings wouldn't work properly with the cold weather and strong wind
72 seconds after launch, Challenger's booster failed and the O-rings were damaged causing smoke since just after launch
January 26, 1986 was more acceptable weather than the next day when Challenger was launched
Launch delayed five days in a row
Challenger exploded, claiming the seven lives on board and the space shuttle
Launch Engineers
Flight crew
Did not note of spiked readings
Made the decision to launch Challenger in inadequate weather
O-rings not suitable for the colder weather
The smoke was not visible from cockpit
Cold temperatures not ideal for launching of the Challenger
The launch of Challenger had been delayed five days in a row
Media and government put pressure on the engineers to launch
Has a history of issues with TRDS-1 and SSMEs
Originally was STA-099, a Structural Tester, made to design and callibrate a new light weight space shuttle orbiter
Escape for the crew was limited and no way out without exterior interference
Cockpit's view and readings of the failing engines caused the downfall of the Challenger and the seven astronauts on board
STA-099 became OV-099, named "Challenger" on January 1, 1979
STA-099 was created as a tester for light weight space shuttle orbiter structure
On January 27, 1986 the Challenger was launched and the booster failed, causing the Challenger and her crew to go up in flames
Engineers
Manufacturers
Astronauts
Crew members, trained and experienced to fly and travel into space
They built the shuttle based off the engineers designs and created the experimental light weight structure. And then made the decision and the changes to convert STA-099 into OV-099
Designed the tester and the changes for the converted orbiter vehicle
Maintenance
Service requirements
Required parts and systems
Trained, experienced and procedures for space flight and orbiter vehicles
Lose of communication between launchpad workers, the crew on the Challenger, ground control and NASA's board for decision-making
Delayed launch for five days due to bad weather
The launchpad workers had worked throughout the night, causing fatigue and bad judgement
No warning systems for the crew to announce the presence of the fire and smoke from the failed booster and the O-rings
Media and the Congress had pressure put on the launchpad workers, the engineers and the crew to launch Challenger as soon as possible
The main part of their job was to get Challenger and her crew into orbit again, for her 10th mission
