According to SpaceX, It looks as if we may have experienced a shutdown condition just after ignition. In these situations the vehicle puts itself into "safe mode". There may be the chance to "recycle" the count and try again.

The Falcon 9 in its simplest form is a "single stick" vehicle with a two-stage configuration. A cluster of nine SpaceX-developed Merlin-1C engines on the first stage, burning kerosene and liquid oxygen. The second stage is powered by a single Merlin engine. The rocket stands 55 meters tall.

SpaceX has a $1.6 billion contract with NASA to deliver 20 tons of cargo to the International Space Station over 12 Dragon flights through 2016. In 2002 SpaceX has been funded by Elon Musk, to develop and launch vehicles capable of reducing the cost put sending into orbit and to allow the development of civil and private space.

Falcon 9 was slated to travel eastward off the pad to orbit about 155 miles (250 km) above Earth. An earlier version, Falcon 1, already has flown into orbit, in 2008 and again in 2009. It took four tries to get it right.
