Poor STS-127 has been postponed 4 times now (hydrogen leak, hydrogen leak, lightning, weather).
They're trying again today. Launch target is 6:51 EDT (2251 UTC).
At this moment, tanking is complete. Astronauts are suiting up.
The weather has a 60% chance of preventing launch. [Corrected from 80% after the weather briefing, but now there are storms forming in the area, so that might be optimistic.]
