I wonder if maybe a second party thread dedicated to post stage separation partying is in order ... And name THAT thread "She's got legs"?

How about just "pants". Covers both the suit aspect and the legs aspect.

Legs For A Suit!

Can't suit-up... my zipper broke....

dorkmo · « **Reply #25 on:** 02/21/2014 12:56 am »

any speculations on the amount of drag caused by legs on ascent? could it be significant enough to lower mass to orbit rating?

Dragon, Suit Up! Falcon, Legs Down!

Of course it is. Nothing is free. SpaceX has made the trade of mass-to-orbit for reusability and lower cost.

For mass, this is certainly true. But the question was about drag, which is much trickier.

Well, it probably isn't a big increase in aero losses, since they're folded up tight to the side during launch and are sitting in the wake of the big, hammerhead fairing.

Dragon is (almost?) of the same size as the rest of the rocket. So for this flight the legs should reach into the airflow, But folded onto the rocket and looking at http://www.spacex.com/sites/spacex/files/landingleg_0.jpg probably not more than a 2 feed (or 60cm). This makes it roughly a square profile instead of a round (diagonal of a square with an edge of 3.6m is 5.09m compared with 4.8m (width with legs is 3.6m+1.2m)). This makes an area increase of 4.0/pi=1.27 or 27% more area.
This is of course a handwaving estimate which could be made at a party, thus ftting here

Motion for the thread title to include a ZZ-Top "Legs" reference.

It feels like Dragon has been lost in the excitement of 1st stage recovery.
Will it have the new parachute system? Probably, More power for GLACIER/whatever... that's it?
They want to put poeople in there. This is SpaceX, what new cabailities will CRS3 have, if any? Super Dracos..don't be silly.

The new parachute system that was tested is for crew dragon, not cargo dragon.

So it absolutely won't be on this Dragon CRS-3?

Indeed. That drop test was a milestone under the commercial crew program. And the drogue location with the that parachute system would not fit under the nose cone with a CBM hatch.

Wasn't the highlight of this Dragon supposed to be a waterproof electrical system?

That and the payload power upgrades, yes. Those are the only notable things, I think.
