The
flight crew arrived at
Kennedy Space Center on Monday, February 25 at
1:00 a.m. EST
At
launch minus 11 hours a planned countdown hold -- called a
built-in hold -- begins.
This hold period can last for up to 13 hours, 25 minutes depending
on the type of payload, tests required and other factors.
This time is also used, if needed, to perform tasks in the
countdown that may not have been completed earlier.
**Due
to the weather postponement of the launch for a 24 hour turn
around, the T-11 hold was extended to 36 hours and 32 minutes.**
