On January 28th 1986 it exploded over Cape Canaveral, Florida. The cause of explosion was because a faulty o-ring seal that caused the hydrogen and oxygen to leak out. The shuttle exploded 73.618 seconds into flight. Below is a website that shows all the conversation that the crew had with CapCom and the exact times in which the instruments responded and when the shuttle exploded]]> 2016-04-18 13:31:15 UTC https://padlet.com/thespacegeekiv/d6cjjquj7ejd/wish/106299647 thespacegeekiv https://padlet.com/thespacegeekiv/d6cjjquj7ejd/wish/106652909 Apollo 1 was meant to be the first of the Apollo missions for a orbital test of all the components that were needed to land on the moon. This would have been an exciting launch for NASA but a flash fire broke out inside the command module of the craft caused by faulty wiring. The hatch door which should have taken them a few seconds to open, took the astronauts about 90 secs. by that time the three astronauts, Ed White, Gus Grissom, and Roger Chaffee lost their lives. ]]> 2016-04-19 21:08:20 UTC https://padlet.com/thespacegeekiv/d6cjjquj7ejd/wish/106652909 thespacegeekiv https://padlet.com/thespacegeekiv/d6cjjquj7ejd/wish/106655187 Space Shuttle Columbia was the first shuttle in the American fleet. On February 1st 2003, it was moments away from disaster. As the shuttle came in for re-entry, heat from re-entry caused the shuttle to break up over Texas. After precise analysis showed that during liftoff, a large chunk of foam broke off of the external tank. The foam, about the size the briefcase crashed into the leading edge of the wing. this created a hole about 25 cm in diameter. This allowed super heated gases to enter the shuttle's hull during re-entry. NASA engineers knew that foam had struck the panels but did not regard the issue as serious. The cause was analysed and found that the hole had occurred on panel 8 on the RCC panels. The chance of a small piece of foam breaking the reinforced carbon carbon panels was never considered to NASA. The RCC were so critical to the shuttle's survival, they were made and were believed to be virtually indestructible. ]]> 2016-04-19 21:30:33 UTC https://padlet.com/thespacegeekiv/d6cjjquj7ejd/wish/106655187 thespacegeekiv https://padlet.com/thespacegeekiv/d6cjjquj7ejd/wish/106794177 The Juno Program was one of the most disastrous programs in NASA history. The first few Juno 1 launches were successful but the last 2 were bad and failed their missions. A Juno I bearing the letters "TI" (Redstone #47) launched from Cape Canaveral Launch Pad 5 on August 24, 1958 failed to carry Explorer V into orbit when the Redstone booster bumped the upper stages, sending them out of control. A second Juno launched followed without a very thorough inspection. Finally, a Juno I bearing the letters "HE" (Redstone #49) was launched from Cape Canaveral Launch Pad 5 on October 22, 1958. The upper stage clusters broke off in an unsuccessful attempt to deploy the Beacon I balloon-type satellite.]]> 2016-04-20 14:42:48 UTC https://padlet.com/thespacegeekiv/d6cjjquj7ejd/wish/106794177 thespacegeekiv https://padlet.com/thespacegeekiv/d6cjjquj7ejd/wish/106895428 The Atlas Centaur V was the biggest explosion in NASA history. The Atlas Centaur V was 34 meters tall and weighed in at 136 metric tons. This rocket was a major advancement from the last one and had more technologically advanced instruments. the launch sequence and launch however, did not go as planned. The rocket's prevalve snapped close and the engines shut down. Barely a meter and a half off the pad, the Atlas Centaur V fell back onto the pad. the fuel tanks and the oxidizers exploding into a giant fireball. The Centaur self-destructed itself completely and also severely damaged the launchpad that it was sitting on. ]]> 2016-04-20 23:23:08 UTC https://padlet.com/thespacegeekiv/d6cjjquj7ejd/wish/106895428
