Default Ares Launch support

I am lurker here, because you guys know this stuff way too much more
than I. Guess that is why I am not a rocket scientist. So I wanted
to ask this question as I must have missed it somewhere.

With the annoucement of the Ares vehicles and such, what are is Nasa
anticipating on using for launch facilities. Will they use the the
LC39 complex?

Secondly with the vehicles being designed as they are, do ya'll think
they will ever use the vandenberg facilites for manned launches?

Thanks in advance all.

Yes.

No.

Ares 5 is definitely planned for launch from Complex 39. Its size and
shape is dictated by the Vehicle Assembly Building.

Ares 1, because construction needs to begin before the Shuttle is
retired (i.e., before the Shuttle is done with Complex 39) is a little
more in flux. NASA is weighing several options...

Overhaul Pad 39B for Ares 1 beginning in 2007.
Build a new Pad 39C for Ares 1.
Covert Launch Complex 40 (former Titan III/IV) for Ares 1.

Overhauling Pad B would be the cheapest method, but would most
interfere with Shuttle operations, particularly the desire for a
rescue launch capability for the 2008 Hubble mission (STS-125).

Pad 39C would be much more expensive, but could be tailor-made for
Ares 1, which might reduce operational costs. It would probably be
located inland, between 39A and 39B, instead of north of 39B where a
third pad for Apollo was once planned.

Pad 40 makes use of a currently vacant launch facility, but is rather
farther from the Complex 39 infrastructure NASA wants to use to cut
development costs.

they will ever use the vandenberg facilites for manned launches?


No. Had NASA chosen an EELV (Delta IV or Atlas 5) to launch CEV, it
might have been pretty easy to do, (Delta IV is flying from the old
Shuttle pad at Vandenberg) but they didn't.

I think Jorge has already posted that one of the LC39 pads is being
eyed for conversion for Ares I starting as early as next year or early
'08. He mentioned this in a very recent message (within the last week
or so).

As for VAFB, the answer is almost certainly no. Not only are the
former shuttle facilities at SLC 6 now devoted to Delta IV use, but
there's no need for polar launches of the Ares family of vehicles. The
site can't be used for equitorial launches due to down-range safety
constraints.

On top of that, I can't really think of much you'd be able to do with the
resulting orbit (polar/near polar) from Vandenberg. (Maybe I'm just not
thinking out of the box?)

Thanks for the answers everyone. I didn't realize the Deltv IV was
laucnhing from that pad, much less how much was different. I was
thinking since they were using Delta IV engines, some might be
similiar.

One last question, why would you only do equitorial launches instead
of polar launches for leaving earth?

Sorry if that is dumb question but just something I was thinking
about.

Thanks

If you launch due east from the equator (or close to it), you get a
free head start since Earth is rotating at 465 m/s. If you launch
north or south you get no advantage and have to provide this energy
yourself. If you launch west, you have to accelerate to 465 m/s just
to stand still, then make the full burn to orbit.

What this means in practice is that you can carry bigger payloads if
you launch to the east.

There are some uses for polar orbits, otherwise there would be no orbital
launches from Vandenberg. But I can't think of any that make sense for
manned missions.
