No Change to Shuttle Ice Frost Ramps
NASA: No more changes to shuttle tank until after launch, Orlando Sentinel
“NASA managers announced today there will be no more major safety changes to the space shuttle’s external fuel tank until after the next planned launch in July. The decision follows a debate among engineers on whether to modify so-called ice-frost ramps on the tank’s exterior before Discovery’s upcoming flight. The small ramps are crafted from foam insulation that is sprayed by hand on the tank’s exterior to prevent the buildup of ice.”
