Columbia Countdown Gets Started

Under a cloak of high security, NASA began the launch countdown for the Space Shuttle

Columbia

on Monday. If all goes well, the shuttle will launch on Thursday at a secret time - the actual launch time will only be announced 24 hours beforehand. The 16-day microgravity science mission was supposed to launch last year, but cracks discovered in shuttle fuel lines kept the whole fleet grounded while a solution was found. Isreal's first astronaut, Ilan Ramon, is also due to take part in this mission.
