You can watch a highlight of the launch of the first Falcon 9 rocket on the SpaceX website:
Details about the Falcon 9:
Like Falcon 1, Falcon 9 is a two stage, liquid oxygen and rocket grade kerosene (RP-1) powered launch vehicle. It uses the same engines, structural architecture (with a wider diameter), avionics and launch system.
Length: 54.9 m (180 ft)
Width: 3.6 m (12 ft)
Mass (LEO, 5.2m fairing): 333,400 kg (735,000 lb)
Mass (GTO, 5.2m fairing): 332,800 kg (733,800 lb)
Thrust (vacuum): 4.94 MN (1,110,000 lbf)
Nine SpaceX Merlin engines power the Falcon 9 first stage with 125,000 lbs-f sea level thrust per engine for a total thrust on liftoff of just over 1.1 Million lbs-f. After engine start, Falcon is held down until all vehicle systems are verified to be functioning normally before release for liftoff.
In December 2008, NASA announced the selection of SpaceX’s Falcon 9 launch vehicle and Dragon Spacecraft to resupply the International Space Station (ISS) when the Space Shuttle retires in 2010. The $1.6 billion contract represents a minimum of 12 flights, with an option to order additional missions for a cumulative total contract value of up to $3.1 billion.
The Dragon Spacecraft, launched by a Falcon 9, besides hauling cargo, was designed to be human crewed. Within three years it could be hauling seven people into orbit.
