During the Sunday orbital commute (channelling Rob Navias) we can post videos of the Dragon pass over the UK (and other places) last night. Some amazing videos on Youtube.
-
You summoned a video! Dragon passing over UK - and the second stage & solar panel covers photobombing along the way. Not my video, but best one I've seen.

Dragon Resupply Mission (CRS-11) passing over Oxfordshire 22 minutes after launch from NASA’s Kennedy Space Center Florida. The two light in the middle are the Dragon capsule and the second stage, the two lights on either side are the discarded protective fairings tumbling away from the craft. Look for a thruster correction burst at 1min 12sec.

And that's it for NASA TV coverage (no installation coverage :( )
Chris Gebhardt's article updated:

Thanks again to centaurinasa for the coverage (drop some likes!)
Thread is still update only, so only mission events in here and such. Discussion in - wait for it - CRS-11 Discussion thread! :)

-
After capture, the crew hand robotics off to ROBO controllers at MCC-H.
ROBO began to maneuver the SSRMS to the "Pre-Install Position" at about 3.5 Meters from Node-2 Harmony nadir Hatch and to allow the crew to make a visual inspection of the CBM "Common Berthing Mechanism" and take images (downlinked to MCC-H for engineers evaluation)

-
The two last step for berthing:
- "1st stage capture": crew closed four latches and started driving bolts (SSRMS in limp-mode)-
- "2nd Stage Capture": four sets of four bolts were driven to secure Dragon in place
-
-
Capcom: "Exercice constraint has been lifted"

ISS config updated...

I heard before, that opening of the hatch would take place today...

2fish working on pressurisation and leak check of the vestibule between Node-2 and Dragon

2fish still on pressurisation leak check....
-
some trouble with the press probe, seems good but MCC ask to try with another probe...
-
Fyodor talking about some Ice cream in Dragon at the end of the DPC ("Daily Planning Conference") ... :D
-
2fish proceed with the new probe
-
Capcom: "You are GO to complete the procedure !"
-
Peggy: "leak check complete"
-
Capcom: "Go for ingress procedure"
-
Here a summary of the ingress procedure:
Once the Harmony Hatch is open:
- Vestibule Outfitting: Installation of air ducts and removal of equipment needed to bolt Dragon in Place.
- Removing MLI ("multi-layer insulation") from the hatchway and 2fish and set up of the tools for the procedure.
- Before openning Dragon's Hatch ,the 4 CPA ("Control Panel Assemblies") are removed and Dragon is connected to ISS Data and Power Systems via redundant jumpers.
- Once the two Hatches are open, wearing protective mask and glasses, the crew perform Air Sampling as part of initial ingress operations and they inspect the interior of the capsule for any damage or FOD ("Foreign Object Debris").
- Then, the air inside Dragon is assessed, before MCC-H gives a GO for Dragon ingress.
-
-
Comparison of Hatch Sizes between russian model (left) and CBM (right)

Jumper installation complete and GO for CPA removal...
-
Comparison of Hatch Sizes between russian model (left) and CBM (right)
What is the comparison with the opening to be used with PDA-2/3 moved to accommodate Crewed Commercial capsules? how will that effect CRS-2 cargo shipments?
-
Peggy: "CPAs are removed"
-
What is the comparison with the opening to be used with PMA-2/3 moved to accommodate Crewed Commercial capsules?
...
It seems (To check ...) that the internal passageway diameter of IDA is the same of russian: 0.80 meter (31 inches)
-
Capcom: "GO for step 5: vestibule config for ingress"
-
Waiting for Dragon's Hatch openning.....
(image from previous flight...)
-
very quiet on the loop...
-
MCC-H: "go for donning goggles and mask "
-
DRAGON's Hatch is OPEN ! 8) :)
-
some congrats from MCC...
-
As Rob Navias say: "That conclude the event !" ;)
-
Peggy report no FOD and temperature condition is perfect !
-
Air Sampling ...
-
Great work centaurinasa!
And a Jack photo from today:
-
how will that effect CRS-2 cargo shipments?
Based on other posts, the refurb Cargo Dragons will continue to deliver supplies and be berthed. Crew Dragons will be mostly crew and some cargo that will fit and will dock.
Crew Dragons may be refurbed if NASA and SX decide there is a need.
-
Looking forward to seeing the same image of Crew Dragon !!

So trunk unloading will start soon.

Mobile Servicing System (MSS) Operations: Overnight, Robotics Ground Controllers maneuvered the Space Station Remote Manipulator System (SSRMS) and Special Purpose Dexterous Manipulator (SPDM) Arm 1 to extract the Multiple User System for Earth Sensing (MUSES) payload from the SpX-11 Dragon Trunk. SPDM Arm1 and the SPDM Body were then maneuvered to stow the MUSES payload on the SPDM Enhanced Orbital Replacement Unit (ORU) Temporary Platform (EOTP). Finally, the SPDM was stowed on Mobile Base System (MBS) Power Data Grapple Fixture 2 (PDGF2) and the SSRMS was maneuvered to a park position.
-
https://blogs.nasa.gov/stationreport/2017/06/08/
Yesterday and overnight, Robotic Ground Controllers powered up the MSS cameras and lights and walked the Space Station Remote Manipulator System (SSRMS) off the Node2 Power Data Grapple Fixture (PDGF) onto Mobile Base System (MBS) PDGF1. They then translated the Mobile Transporter (MT) from Worksite 6 (WS6) to WS2. Finally the Robotics Ground Controllers unstowed the Special Purpose Dexterous Manipulator (SPDM) from MBS PDGF2. The SPDM is holding the Multiple User System for Earth Sensing (MUSES) payload on the Enhanced Orbital Replacement Unit (ORU) Temporary Platform (EOTP) which will be installed later today on Express Logistic Carrier 4 (ELC4).

Deployment was attempted this afternoon but was unsuccessful. Latches were locked while teams discuss the next steps with NICER engineers.

Looks like the FRAM remains attached to the Dextre effector right? It appears there was an emergency separation mechanism to permit jettisoning the voluminous array itself.
Interesting also how the SPDM is grabbing the FRAM with both arms to better rigidize the system.

And why we test.

ROSA has been jettisoned by SPDM, The roll up did not lock !
So, did it redeploy by itself as soon as the roll-up motor was de-powered?

No it was redeployed and locked out in the deployed position to guarantee maximum rigidity for jettison from its FRAM-to-ESPA adapter.
