1 Day to Launch!

SORCE Mission Activity –

SORCE has successfully completed the Launch Readiness Review, which took place at 9:00 a.m. EST this morning. After reviewing the overall launch plan, all systems are GO! Launch remains set for Saturday, January 25 from Kennedy Space Center (KSC). There is a 58-minute window for the launch to occur beginning at 3:10 p.m. EST, 1:10 p.m. MST. If for any reason the launch needs to be delayed on Saturday, there is a second launch window on Sunday, January 26, with the same launch time.
Weather is one issue that decision makers need to consider. In spite of the uncharacteristically cold temperatures that Florida is experiencing today, this will not affect the SORCE launch in any way. At this time, there is a very, very limited chance (10%) that weather could delay the SORCE launch.

According to, Cape Canaveral is forecasted to be 58 degrees F (at noon), winds from the N-NE at 9 mph, mostly sunny with scattered clouds, 0% precipitation, and 53% maximum humidity for Saturday, January 25, 2003.
