The space shuttle Discovery has returned to NASA’s massive Vehicle Assembly Building to get a new, modified external fuel tank for its upcoming mission. The redesigned fuel tank has a heater on board that should help to minimize frost and ice buildup that could fall off and strike the shuttle during launch. Discovery will roll back out to the launch pad in mid-June, carrying its Italian-built Multi-Purpose Logistics Module Raffaello. NASA is targeting to launch Discovery on July 13, 2005.
