Finally some real excitement is returning to our space program.

And it isn't just SpaceX. Dawn will be at Vesta in two years.

The destroyed remains of an asteroid planet. Wow.

Since the Dragon won't have any engine systems aboard, are they just
going to let it decay from orbit, or is this flight suborbital?

I don't think it's intended to be suborbital. But if they even won't
bother to separate the thing from the second stage it will probably
decay fast.

??? It's supposed to have an RCS , no?

The actual Dragon is supposed to have an RCS - but they are launching
the qualification model, and it's not entirely clear how close to
completely operational it will be.

(from: http://www.spaceflightnow.com/news/n0909/24falcon/):
:"This is the actual article used to qualify Dragon for flight loads,
:so it is identical to the flight article as far as the core structure
:and mold line, but will not carry engines or avionics, therefore it is
:lighter," said Elon Musk, SpaceX's billionaire founder.

Which strikes me as *very* odd, because one of the reasons for doing
this was given as:

(from the same source)
:"This gives us the best flight data in advance of our first COTS mission,"
:Musk said. "It also removes the (payload) fairing from the schedule critical
ath and allows us to spend more time on making the fairing lighter and more
:reliable."

Which sounds fishy as hell... Almost like there is a problem with the
fairing, and thus they are unable to launch the (as yet unannounced)
originally intended payload.

From what I read, this first one will be pretty much inert, and the
second one will have a operational RCS.

Hmm, now that you mention it, that does sound odd...but they probably
want to get Dragon up and running ASAP, so they can get a major lead
over Orbital Sciences.
