A problem with the shuttle's fuel shut-off system causes delays, but NASA is reporting that the craft is back on the launch platform,
and they are expecting a launch date of no sooner than July 1st.
We all hope that the physical changes to the booster rockets will let the craft avoid getting damaged during take-off and a complete
Discovery Shuttle can return to earth unscathed.
New technologies in place include a 50ft arm for use in examining the craft in space to check for launch damage, and modified booster rockets that will reduce the amount of insulation that breaks off during launch! Read more about these and other changes on the
