The clock is once again ticking down, and liftoff of space shuttle Endeavour on its STS-134 mission to the International Space Station is a little more than an hour away. Coming up at 8:07 a.m. EDT, the countdown will pause again at T-9 minutes for the final planned hold.
Today's countdown continues to go relatively smoothly and weather at NASA's Kennedy Space Center is cooperating, with favorable conditions still predicted for launch time at 8:56:28 a.m.
