Work continues to assess and repair hail damage to the Shuttle Atlantis' external tank. The tank was damaged by hail in a severe thunder storm on February 26. A new launch date has not yet been scheduled.
These images explain why it's taking so long. Technicians sand away the red dye that has been applied to the external tank to help expose cracks or compression dents.
And you thought our space program was high tech.
