NASA gets back to work to fix new cracks on space shuttle Discovery tank
Discovery tank
The next few days will be busy at the Kennedy Space Center, as NASA begins working on three support beams, called stringers, on the shuttle's external fuel tank.
NASA discovered new cracks at the top of the stringers last week while analyzing the tank.
Managers decided Thursday to fix the cracks in a similar way as technicians repaired cracks on two other stringers, which were discovered after Discovery's failed launch attempt in early November.
The new repairs should take two to three days. After that, NASA will review data from the repair work to figure out if more needs to be done.
Mission managers are also scheduled to meet Monday to decide whether they need to make further modifications on some of the support beams. A decision on that could come as early as Monday.
