SpaceX will be trying again
After their first launch of the Falcon 1 rocket went awry seconds after liftoff a year ago (March 24), Space Exploration is about to try again. This time, they've even got a live webcast covering the event. (It's at http://spacex.com/webcast.php )
Unfortunately, today's attempt was halted at T minus 1 minute 30 seconds, and it's not clear what the cause was. Such things are normal and expected in the rocket biz, especially with a brand new design. Nothing to worry about. They've scrubbed for today, but they've said they could reschedule for another try tomorrow or the day after.
Kimbal Musk, brother of SpaceX founder and president Elon Musk, keeps a nice firsthand blog on launch events, from right there on Kwajelein Atoll in the Pacific, where these intial tests are being carried out (see it here: http://kwajrockets.blogspot.com/ ). The operational launches will be from spaceports in the US.
Here's a view of the pad, from the live webcast:
