The Space Shuttle Endeavor was scheduled to lift off at 3:47 this afternoon. But the mission was scrubbed after NASA officials discovered a faulty heater around noon. The launch is postponed for at least 48 hours. When it does go up, it’ll be the last launch of the Space Shuttle program. Astronaut Stanley Love was part of the Atlantis shuttle mission in 2008. He says part of the reason NASA is ending the program is because it did not fully live up to expectations.
