I wonder if the launch will push past the net than February announcement?

Will they be sending up a dummy in a SpaceX suit to test umbilicals, env system, etc under launch and re-entry conditions?

NASA wants a new Dragon 2 each mission, it doesn't mean SpaceX isn't going to reuse them for something else. Maybe cargo missions or free flight missions.
What’s funny is we had this exact same discussion in 2010 about Dragon 1. And NASA eventually accepted reused Dragon1. They’ll take reused Dragon2s, in time.
I recall NASA being quoted on these forums as stating that it was SpaceX that only proposed new Dragons for each mission. I presume that was because they didn't want initial flights held up by the rectal exam that will be recertification procedures and validation thereof.

Yes, we did have a similar discussion (several times)...
NASA did not require a new Dragon for each CRS mission; NASA wanted a firm price. It was too early to make a commitment to refurb Dragon pricing--too many unknowns. The safe-conservative path was to price based on new Dragon for each mission. (That was briefly articulated during one of the early CRS post-mission press conferences, but I cannot find the reference.)
Eventually they worked it out to everyone's satisfaction for CRS. Presumably same will happen with Crew Dragon (and Starliner). Expect they have a better handle on what refurb will entail with Crew Dragon, but nailing down the details is likely a low priority at this time.

No, Starliner won't need satisfaction of anyone over time, Boeing will start reusing their capsules right from the beginning, they're being certified to up to 10 uses. The first Boeing crew rotation mission will use the capsule from the uncrewed test flight.

I assumed that, and expected that everybody here would figure that out too. Though I was confused for a little bit by the vertical orientation of the capsule door. Until I compared it with another Dragon 2 image (in fact, the very one you posted above).

Good for them; thanks. Let's hope SpaceX gets it figured out reasonably soon given water landings.

Note, the "over time" is the key portion of that statement. By proposing all new Dragons SpaceX deferred any work on certifying used capsules. By proposing immediate capsule reuse, Boeing will need to satisfy NASA of their recertification procedures from the start, as part of their overall certification effort. And since their first crewed flight is a reused capsule, any deficiencies found in that procedure has potential to delay their first astronauts.

The first crewed flight for Boeing will be on a new capsule, their second crewed flight which will be their first crew rotation mission will use the reused capsule. They will have some time considering there may be at least 1 year or more between the first use of the capsule and its second use. Anyways, this is for DM-1, not Boeing's Starliner... it's my fault

Good point. They will not know what needs to be done until they get one back. Which introduces cost and schedule risk. Let's hope and expect everyone has done their homework and that the impact is minimal.

SpaceX also happens to hold resupply contract they can use reused capsules on - so there is no rush to shut down the production line after the first three or so. They have the business to keep quite a few capsules in rotation.

Photoshop? I've enhanced the image which is an overall purplish colour, while the sign is more orange coloured. I don't see a reflection of the pole on the ground, lilke I can see with the side rails. There's also no shadow behind the sign.

Could be. Still funny though.

Yes, I know that. My message was in reply to #465 where the question was asked was the photo Elon Musk posted the view of the Dragon from the crew access arm. I was confirming it was by posting another view of the capsule with the same door layout.
