However, the space shuttle program was marred by two major tragedies. On January 28, 1986, the space shuttle Challenger exploded 73 seconds after liftoff. All seven people on board died, including a teacher named Christa McAuliffe. McAuliffe would have been the first civilian in space. The second tragedy occurred on February 1, 2003. The shuttle Columbia was returning from a 16 day research mission when it disintegrated while reentering Earth’s atmosphere. The seven person cred died. After each of the disasters, space shuttle operations were suspended for more than two years. Based on the text, which of the following statements is true.

A	Challenger exploded at the beginning its mission and Columbia exploded at the end of its mission
B	Both the Challenger and the Columbia disasters had survivors.
C	The text doesn’t say.
D	None of the above

Explanation:

Detailed explanation-1: -The final space shuttle mission, STS-135, the last flight of the orbiter Atlantis, lifted off from Launch Pad 39A at NASA’s Kennedy Space Center (KSC) in Florida on July 8, 2011.

Detailed explanation-2: -STS-1 (Space Transportation System-1) was the first orbital spaceflight of NASA’s Space Shuttle program. The first orbiter, Columbia, launched on April 12, 1981, and returned on April 14, 1981, 54.5 hours later, having orbited the Earth 37 times.

Detailed explanation-3: -While reentering Earth’s atmosphere, Columbia broke apart, killing the entire crew. All of these factors-high costs, slow turnaround, few customers, and a vehicle (and agency) that had major safety problems-combined to make the Bush administration realize it was time for the Space Shuttle Program to retire.
