Introduction

With flags at half mast and wreaths, the NASA remembers Friday the astronauts who died on space missions in the week that marks the 25th anniversary of the disaster of the space shuttle 'Challenger'.

Short Shape Science (2012) stated that On January 28, 1986, America was glued to the TV thinking space. NASA was going to put the shuttle Challenger at 11:38 am local time. It exploded 73 seconds later. The tragedy shocked a nation that saw live how the spacecraft disintegrated sweeping away the lives of seven astronauts, among whom stood the teacher Christa McAuliffe, the first civilian who traveled to space. The previous day had turned 19 since the three Apollo 1 astronauts died during a test launch, but the Challenger accident was the first after takeoff. The shuttle mission was flight number 25 of a space shuttle and should have lasted seven days. The bad luck of six joined Apollo 1 launch delays, completed setting for the January 28.

According to Denton (1997) many people saw the launch live as the crew was Christa McAuliffe, the first member of Project Teacher in Space. The coverage of the media about the accident was extensive: one study found that 85 percent of Americans surveyed had heard the news during the hour after the accident. The Challenger accident has been used as a case study in many discussions of engineering safety and ethics.

Handberg stated that (2003) the crew of the space shuttle Challenger suffered a tragic accident on take-off of STS-51-L. For the second time after the accident Apollo1 and suspense that followed the return of Apollo XIII, NASA reliving what she feared most, losing a crew during a mission. The Challenger disaster and the Challenger accident is an accident occurring Space and which resulted in the loss of the Space Shuttle Challenger and its crew consists of seven members.

The crew compartment and other fragments of the ship were eventually recovered from the ocean after a long search and recovery operation. Although no one knows the exact moment that killed the crew, we know that some members survived the initial breakup of the ship. However, the shuttle device had no emergency exit and astronauts did not survive the impact of the shuttle against the surface of the ocean (Handberg, 2003).

Vaughan discoursed that (2000) the accident was caused by a malfunction of the O-rings, gaskets a must to ensure perfect sealing of the booster rockets. The night before the accident was especially cold, which made the boards did not close well and there was an escape of gas. The gas leak drilled the main tank of fuel, which ended in flames. The Challenger was exposed to an uncontrolled supersonic flight, which led to its disintegration (Denton, 1997).

But the Challenger disaster was not the last tragedy of the shuttle ...
