In the Countdown Status Briefing today, NASA confirmed that the Discovery STS-119 mission will attempt another launch on Sunday at 23:43 UT. Currently repairs are underway to fix the leak that caused the previous two scrubs. NASA official remain optimistic that the problem would be resolved on time and with the weather at 80% for a “go”, Sunday seems likely to be the first day of the STS-119 mission. In the unlikely event that the leak is not fixed, NASA could also attempt to launch on Monday and Tuesday. If that window is missed, however, the shuttle won’t be able to take off until April 7.
If Discovery launches on Sunday, the mission will last 13 days and include 3 spacewalks (EVA’s). The Mission Management Team will meet tomorrow at 17:00 UT to make the final “go” – “no go” decision. The meeting will be followed by NASA news conference (L-1 briefing). If everything goes according to the plan, the L-1 countdown will be restarted at 08:11 UT on Sunday; astronauts will suit up a few minutes before 19:00 UT and head to the launch pad. NASA’s Discovery Launch Coverage will start at 18:30 UT on NASA TV and shuttle commentary will be available 24/7 for the duration of the mission.
