On the great DCSS L2 section, the notes confirm no fairing. Some epic new videos on there.

Got confused there for a moment.

At least this isn't launching on DIV, otherwise we'd be looking at a DCSS on a DCSS.

cheers, Martin

Maybe a 1st test flight in a shroud? You could prove out the vehicle on orbit and during re-entry without solving the boost phase aerodynamics until later.

Sorry, I probably should have mentioned that in the article. Yes, no fairing needed.

I have a question about the Dream Chaser and Mars.

Can Dream Chaser be used as a Mars entry vehicle?  Or is the atmosphere on Mars too thin for a descent decent?

I think the Dream Chaser kinda need a runway to land on, unless it is just a "shell" for the entry and dropped before a more standard Mars landing can be performed

I'm still about foggy on the launch abort system?

Wow!? That seems like it would be a bit dynamically hairy with a vehicle like that? Would they then eject from D.C.? Don't get me wrong I love the concept but each and every year I appreciate more and more the KISS principle. I just want us accomplishing amazing new things and not over think how we get there.

I can't envision any type of pad abort with any type of vehicle or system that wouldn't be a bit "dynamically hairy".

They would attempt to fly it back with the goal of a runway landing. 

I would not say this violates any KISS principle.  Use the main engines, fly back.  No additional abort system, no ejection seats.

Well this is probably just my perception then. Pulling a "pod" off the top of the rocket and dumping it ballistically into the ocean seems simpler. So D.C. can pad abort and make it to the Shuttle Landing facility from Pad 41?

CCAFS also has a strip. KTIX is right across the sound, but I doubt the crew would want to work a spacecraft into the traffic pattern with the rest of the bug-smashers! :)

Supposedly they're going to do an uncrewed test.  I'll be excited to see video of that!

You know, I just assumed it was the SLF, but they didn't actually say that.

Not necissarily.  Assuming an intact abort, the range and cross range that the DC offers actually allows one to know where it is coming down as opposed to just dropping somewhere in the water and waiting for someone to come and fish them out.

If anyone has contact info for S.N.C I might be able to make that happen.  ;) :)
