Just curious as to what this quickdraw-come-chest harness(?)-come-braces setup that astronaut Mike Hopkins is wearing is all about.

I'm not one to question the rocket scientists but I cant help but be reminded of that climbing gear fashion article from a while back!

Any ideas as to the purpose?

is its purpose to put an X on him so we all know he came from a spacex craft!?

They are lifting points to haul them out of the capsule if nescessary, there's a full description on MP.

In reply to jimtitt:

MP...?

Google finds lots of members of parliament...

mountain project - us site with lots of technical talk and intersting stuff

In reply to lithos:

Thanks; I was thinking it would be a space-related site...

Interesting. The commenter on MP says that the orange straps are integral to the suit, rather than being slings, but it's still not very clear why they used a couple of off-the-shelf BD quickdraws as part of the haul system, rather than something custom made. I'm sure they'd work, but it's not exactly what they're designed for - and after spending all that money on developing the Crew Dragon, did someone really just nip down to REI and pick up a set of eight draws? It's just odd.

At least they appear to have them the right way up.

You can't pop down to REI to buy a crew re-entry vehicle. But you can buy perfectly engineered,  lightweight quickdraws. Why spend more money than you have to? This isn't an old skool, $5k shovel operation...

In reply to GarethSL:

Well I think it looks odd too.

Perhaps there's a chunky lifting loop on the back, but imagine if one of those krabs got twisted while lifting you...?

And if you're supposed to clip into the front, well which bit would you clip into that can't slip?

I think it’s cool that sometimes something off the shelf can be just perfect for something it wasn’t designed for....

In reply to Dan Glynn:

I'm imagining it and it's not filling me with dread, given that it's for an essentially static bodyweight load.

I agree that it looks a little odd but that's not the same thing as actually being dodgy.

I’ve seen things on tv / documentaries where caribener’s are used for non-climbing applications and it looks weird to me purely because it’s something I’m so used to seeing in one specific environment all my life whereas to someone else they wouldn’t even think about it. 
 

At the end of the day if you need some fabric with a  lightweight rated clip at each end why would you use anything else than a climbing QuickDraw or sling set up?

It was more about a twisted krab digging into or between your ribs. It's not very smart compared to a typical chest harness, and there's no obvious clip in point at the front. If it's integral to the suit, it's a pretty poor effort imo.

In reply to Iamgregp:

Yeah, I remember that. I guess the vibrators fire up when you launch a nuke...

If you read the description you would understand better.

Ok, I read the "description"....

"Part of a contingency to hoist astronauts from the capsule that wasn't needed. The orange straps aren't criss crossed slings around the back, they're independent sewn terminations that are integral to the suit. Bright orange webbing indicates its a structural hardpoint on the suit that can support the entire weight of the person inside. Using the 2 bottom straps makes a sit harness for a conscious person, using the top 2 is a full body harness lift from the shoulders to get a floppy unconscious person out of the capsule, and there are additional straps not pictured in a small pocket near the wrists that you could lift someone in an arms up position from the sleeves to get someone out of a hole too small for their shoulders. Quick draws are some prerigging that lets you quickly choose sit harness or shoulder harness by detaching 1 side."

The above is one guys opinion on a climbing forum. Perhaps he's right but they look awfully tight to be able to simply detach from an unconscious person.

In reply to captain paranoia:

Ha!

Actually come to think of it, once when I was in Paris I saw a policeman who attached his sub machine gun to his vest using a quickdraw.  The rest of them all had some specialist looking clip thing for taking the weight of the weapon, but he's switched his out for a well used looking Petzl quickdraw.  Pretty sure he must have been a climber...

Remember whence the word 'karabiner' comes - or 'mousqueton' in French.

In reply to Ian Parsons:

I actually didn't know the etymology of the word so just looked it up!  That's interesting....

Interesting, given that the word "carabiner" originally meant a clip for attaching your carbine (a compact rifle or musket with a shorter than normal barrel) to a belt or bandolier.  Though why that requirement would be specific to carbines rather than longer-barrelled weapons I'm not sure.  Maybe it's because the original carabinier were most often cavalry troops, and it would be easier to access a firearm on horseback by unclipping the strap rather than having to lift it over your head (and possibly risk tangling with the reins)?

I'm presuming if he's in a seat then they will be looser than when stood up ? Either that or they use another krab to clip onto the QD to whichever point they need at the time ?

Heresy! These crabs are not bog standard, off-the-shelf crabs, they are black and therefore TACTICAL!
