"This is a major hardware milestone for our company. It marks the first time that we have simultaneously fired two engines on the same stage," said SpaceX president Elon Musk.
The achievement clears the way for more multiple-engine tests and a Falcon 9 test flight scheduled for later in 2008.
SpaceX plans to steadily increase the number of simultaneously firing engines on the rocket over the next few months. A three-engine test is scheduled for February, to be followed by a five, seven, and finally a nine-engine test.
