WATCH: SpaceX Rocket Explodes Right After Liftoff

A SpaceX rocket exploded right after liftoff today in Cape Canaveral on an unmanned resupply mission to the International Space Station.

NASA, SpaceX, and SpaceX founder Elon Musk immediately tweeted out that something had gone wrong:

The vehicle experienced an anomaly on ascent. Team is investigating. Updates to come.

Falcon 9 experienced a problem shortly before first stage shutdown. Will provide more info as soon as we review the data.

There were, of course, live streams of the liftoff, and lots of people tweeted out pictures of the explosion:

Update- 2:03 pm EST: Musk tweeted out details later:

There was an overpressure event in the upper stage liquid oxygen tank. Data suggests counterintuitive cause.

— Elon Musk (@elonmusk) June 28, 2015

That's all we can say with confidence right now. Will have more to say following a thorough fault tree analysis.
