Apologies if this is the wrong thread, but do we expect Crew Dragon to be bright enough for ground sightings once it reaches orbit and before ISS rendezvous?

Yes. and after it undocks.

As it goes overhead, it'll be roughly magnitude 0, or slightly dimmer than the brightest star in the sky. It should be fairly easy to spot.

Is this the first time the 24/7 NASA TV has gone above 1 million views? And is this is the first time three simultaneous streams hit 1+ million views.

So what's the plan if the access arm gets stuck in the retracted position? Lower the rocket with the astronauts in it?

It would require both joint sets to fully lock up. Highly unlikely to happen. Also, there is a manual override for the rotating mechanism.

Is it just me or does the 2nd stage that separated look suspiciously like the trunk? Is that normal?

Anyone else really impressed by the flight displays the crew has available? It reminds me of the awesome yet totally unrealistic MFDs from Orbiter...

Wish we could get some high-res screenshots or something of all the different screens to see what the crew can really see...

The camera was on the second stage looking at the trunk.

Hey does anyone know why they announce "FTS armed" right before take off?

Since they are doing crew-first loading, I thought FTS is armed when the rocket starts fueling.

Quick question - what is a phasing burn?

Falcon FTS armed. Dragon LAS was armed prior to fueling.

13 additional spots of the 30 trending are launch related

That looked like a surprisingly smooth ride.

Just adjusting altitude and orbital period a little bit to “catch up” with the ISS.

How does that differ from a boost burn?

@NASA posted this tweet and then deleted after a few seconds for some reason
