NASA has scrubbed the first landing opportunity this morning due to inclement weather at the landing site at the Kennedy Space Center in Florida… so no sonic boom for Alabama around 7:30. However, they are still holding open the chance of a “second opportunity” landing at 9:23 a.m. CDT/10:23 EDT.
If the weather improves in time for the second shot, Discovery will crisscross the United States on its trip home from the International Space Station. The streaking, glowing trail should be visible from the ground as the shuttle passes above Alabama in the 9:00 to 9:10 a.m. time frame.
You could very well hear a double sonic boom as the shuttle passes overhead at Mach 10 as well. But again, there is a chance the second opportunity landing could be postponed as well due to weather conditions at the Cape. Stay tuned…
