Detailed explanation-1: -The Space Shuttle program was expensive to operate, and maintaining the twenty-plus year old Orbiters was getting more costly. The Space Shuttle was essential for completing the ISS, but would not be helpful for the new program (called Constellation) that would take us out of low Earth orbit.
Detailed explanation-2: -With 135 missions, and the total cost of US$192 billion (in 2010 dollars), this gives approximately $1.5 billion per launch over the life of the Shuttle program.
Detailed explanation-3: -Jul 16, 2012-NASA’s space shuttles flew their final missions in 2011, finishing each with a touchdown on the Shuttle Landing Facility (SLF) runway at Kennedy Space Center in Florida. Permanent reminders now mark where Discovery, Endeavour and Atlantis each rolled to a final stop.
Detailed explanation-4: -Orion is NASA’s new spacecraft, built to take humans farther into space than they’ve ever gone before. It will carry the crew to space, provide emergency abort capability, sustain the crew and provide a safe return to Earth.
