'CAPE CANAVERAL -- NASA managers said Friday that 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.
There's two distinct possibilities to this whole situation. Either this "debate" has more to do with worry wart engineers trying to 'CYA.' Or, Nasa managers have made a decision that could be putting the lives of Astronauts in danger.
Only time will tell.
