The SRBs use solid rocket fuel which can't leak. The external fuel tank and orbiter use liquid propellants, which are liquified (very cold) hydrogen and oxygen. While on the pad, it will vent some hydrogen and oxygen due to the heat of the atmosphere on the tanks causing some of the liquified fuel to heat up and become gaseous.

Actually, the Space Shuttle replacement (the Constellation Program) will use a Saturn V-like Ares rocket (scheduled for a test flight in late August or early September) and is being patterned after the Apollo launch delivery system. This is necessary for lunar and Mars missions. A smaller rocket will be used for earth orbit missions.
