SpaceX Falcon 9 / Dragon 2 : SpX-DM2 : May 30, 2020 : DISCUSSION

Correct. Inner hatch opened and the view is down the PMA to the vestibule hatch.

Not sure, but I believe we are looking at the inner PMA hatch; beyond that is the vestibule and the outer PMA hatch, and right behind that hatch is the Dragon hatch. Anybody know better?

Announcer just confirmed 2 more hatches, looking at PMA then IDA then Dragon

I assumed they were some sort of e-ink device as they seemed to have constant display during ingress till liftoff.

During the either pre-launch or ascent coverage they remarked that they are iPads, but have covers that can be written on (white board type surface, I assume). I think you're looking at the covers, not the tablet screen. No link sorry, just mentioned on the stream, and my memory may be faulty.

Dragon capsule is Endeavour.

Yawn
Is there a historic name with less connotation?

Well it was their personal choice, so it has a lot of connotation for *them*. Both of them had their first space flight on the Shuttle Endeavor.

All space geeks will have an opinion. I'm totally happy with Endeavour.
The guys who made the choice are the ones who strapped their pink fannies on the pointy end of a Falcon 9.
Go Endeavour!

I did neglect the practical considerations for the name as a call sign.
Endeavor is not too short and not too long, easy to distinguish if the connection is noisy.
And it does reflect a continuation of America's "manned" space program.
Go Endeavor!

The obvious way to have a mic would be over a blue tooth link (or if NASA were doing this, some new standard they'd invent at great cost).

Bluetooth is not the kind of technology I'd expect to see in a spacecraft. It's finicky even in regular consumer applications, the protocol is rather complex for reasons that make no sense in spaceflight applications, and if things go wrong, figuring out what went wrong and how to fix it is not easy. Take COTS components and pray it works is probably the only approach that favors Bluetooth.

That said, Bluetooth is not the only wireless option. There are non-Bluetooth microphones easily available.

Bluetooth works fine for simple things like headphones and microphone to computer. Once set up, it's reliable, and a lot better than a 12 foot cable.

Of course there are other standards and wireless methods. The fact that none of them are used, would suggest wireless isn't allowed on Dragon. Is that correct?

A quick Google says that there is WiFi on the ISS.

Anyone know what type of tablets they are using on their leg pouches? Heard report of 66 and 32 charge on them.

Chris G on NSF livestream is calling them iPads.

I assumed they were some sort of e-ink device as they seemed to have constant display during ingress till liftoff.

The tablets are inside that pouch. You're not seeing the screen on their leg pouch.

Being VERY parocial I saw that Chris Cassidy just stowed the visual alignment cross from the docking target.
On it is the STORRM IR lidar "clip-on" target.
(It's the box on the cross itself. There are four more clipped to the periphery of the target itself.)
I worked on those back in the day!
I wonder if they are still functional after a decade of facing into the stream of atomic oxygen.

Wasnt that system tested during one of the final Shuttle missions?

Yes

What's the real name of the "hatch cozy" that Cassidy put on the hatch after removing the target?

[haywoodfloyd]

I believe that the large canister that Doug removed from stowage was a lithium hydroxide canister?

[ulm_atms]

Doug hit his head 

EDIT: Woops...wrong name :-)

[ShaunML09]

I think Doug hit his head and has a cut ?

[Hog]

Did Doug bump his head?  He kept wiping the right side of his forehead and looking at his hand as if he had a small nick.

[haywoodfloyd]

Bob hit his head 

Which item on the checklist was that?

[Hog]

ISS crew is like "Ah, clean and fresh smelling crew members."

[JMS]

Surprised to see the dignitaries maskless and sharing a phone receiver.

[ShaunML09]

Sounded like it was rougher ride to space than the Space Shuttle

[Prettz]

This guy talking is making every very awkward.

[abaddon]

1st stage smoother than SRBs, 2nd stage rougher than Shuttle post SRB sep.  Probably reflective of the mass of Shuttle versus Dragon and a throttled down Merlin being chuggier.
