The test itself is to launch the second stage towards the orbeit. The big question is, can they make the three cores work as well, as the single F9 core does?

The test itself is to launch the second stage towards the orbeit. The big question is, can they make the three cores work as well, as the single F9 core does? As they have excessive load capacity for the second stage with this test mission, but no commecial cargo to transport, if Elons tweets are to believed, they plan to send his 2008 Tesla Roadster into a Mars orbit. Beyond winning any award for sillyness, if SpaceX manages to do that, it would be the first private mission to the Mars orbit, which would be another big feat.
