CAPE CANAVERAL, Fla. - A crack in the insulating foam of Shuttle Discovery's external tank discovered during a post-scrub inspection may delay Tuesday's third scheduled launch attempt, according to media partner Florida Today.
The first two launch attempts on Saturday and Sunday were scrubbed due to unacceptable weather conditions.
NASA's mission management team is meeting at this hour to discuss a range of options, including repairing the crack prior to launch or flying Discovery as-is. It remains uncertain if repairs of this nature can be accomplished at the launch pad or how long such repairs will take.
Current plans call for NASA to launch Discovery on STS-121 mission on Tuesday, July 4 at 2:37:51 p.m. EDT (1937:51 GMT).
NASA will brief the media upon completion of the mission management team meeting. We will post that information as soon as it becomes available.
