Obviously for this demo it’s ripley in the cabin so it doesn’t matter. But for actual manned missions will the cruise time to the ISS be as long? While the dragon capsule is pretty roomy, 27 hours seems quite a while, will it be quicker?

Soyuz capsules take 2 days to transit to the ISS...

Really. That must be uncomfortable.

how long did the shuttle take?

Two to three days as well (fairly standard)...I believe it was pretty much the norm for ISS docking to be on Day 3 of shuttle activities.  Soyuz has done it in ~6 hours (like MS-11) a few times.  Not sure about future Dragon 2 / Starliner flight times to the ISS ... but I'd imagine they will be around 2 days as well.

Seems like a long time. I know it’s jot much longer than a long haul flight though, just seems excessive.

Brady Kenniston nails a nice pic of LC-39A's clad & unclad quadrants.

You have to bear in mind that once they're in orbit, the only real fuel they have is that needed to de-orbit the ship. They can't really blast up to the ISS then slam the retro-rockets on as 1) there aren't any retro-rockets, and 2) they don't have the fuel capability.  All they have is enough for the little maneuvering thrusters, so they have to creep up slowly and safely.

They not only have the Draco engine's de-orbit and maneuvering props but also the unused SuperDraco's props that would have been used for a launch escape. Same stuff.

Yes, but that hardly lets them blast up to the ISS, slam on the rockets to brake quickly, and then dock all in a few hours...

Why is the live stream so far behind? They've only just called 1000 meters...

Passed Waypoint 0, under the station, moving to Waypoint 1 - 150m in front of station as nd in line with the docking port.

 

R-bar = line from center of station to center of Earth

 

V-bar = line from docking port  along ISSs path

 

Ahead of schedule!

I don't even bother with the chat anymore. Immature snowflakes and their polar opposites.

 

Just inside of Waypoint 1 ISS will send a retreat command, a test of the safety system. If good data it'll approach to ~20m.

Retreat test commanded at 140m. It'll back off to 189m then hold. Good data and it'll approach to 30m.

Crew Dragon did retreat as commanded.
