Space X launch scrubbed, flight aims to test safety procedures
Space X is gearing up for a crucial test that could help send astronauts to space from U.S. soil for the first time in nearly a decade. The unmanned Dragon capsule will intentionally break off from the Falcon 9 rocket minutes after liftoff Sunday. The unmanned in-flight abort test aims to prove Space X can return astronauts to safety in the event of an emergency. Mark Strassman reports from Kennedy Space Center in Florida, where Saturday's launch was postponed due to weather.
