Phoenix launch delay

Friday's scheduled launch of NASA's Phoenix
Mars Lander aboard a United Launch Alliance Delta II rocket has been
postponed 24 hours. The two available launch times on Saturday, Aug.
4, are 5:26:34 a.m. and 6:02:59 a.m. EDT.

Due to a forecast for severe weather around the Kennedy Space Center
launch pad in Florida on Tuesday afternoon, fueling of the second
stage will not be completed. Although fueling is expected to be
finished Wednesday morning, there is insufficient contingency time in
the schedule to move forward with the launch on Friday.
