Update for 2:34 p.m. ET: Another Falcon 9 launch attempt is planned for 2:45 p.m. ET. This will likely be the last try for today. If no go, another launch window opens from 11 a.m. to 3 p.m. ET Saturday. SpaceX's first attempt to launch its Falcon 9 rocket, seen as a private-sector successor to the space shuttle fleet, was aborted with just a second or two left in the countdown at Cape Canaveral Air Force Station in Florida. That doesn't mean we're done for the day. The California-based company could still turn around and make another try once they figure out what went wrong. For background on the Falcon 9 launch and why it's so important (and risky), check out Thursday's posting on rocket roulette. And stay tuned for updates, initially via my Twitter feed. SpaceX is providing a webcast, but Spaceflight Now's coverage (with Miles O'Brien) is more reliable.
