This is on the INTERIOR.

Russian norms are for constant 8 hours/day concentrations. I found following in https://www.nap.edu/read/5170/chapter/15#362 :TABLE 11-3 Spacecraft Maximum Allowable ConcentrationsDuration ppm mg/m3 Target Toxicity1 h 400 1000 CNS depression, irritation24 h 100 240 CNS depression, irritation, hepatoxicity7 d 60 150 CNS depression, irritation, hepatoxicity30 d 60 150 CNS depression, irritation, peripheral nerve damage180 d 60 150 CNS depression, irritation6 mg/m3 is nowhere near any dangerous levels.
Reentry on Friday will be on a Descending Node, with Crew Dragon cutting across North America from Vancouver, British Columbia to Georgia in the pre- and post-dawn hours (depending on location) as she heads towards splashdown off the east coast of Florida.Those under the flight path (the orange line in this image) might have the opportunity to see reentry if conditions are right.(Image: GoISSWatch app)

It looks like I will be more or less directly beneath this path, though likely too far north (Tennessee) to see plasma. It's also predicted to rain most of the day but still ...
Based on the "EARTH STAYS" message in the orbital ops update thread, I guess ISS has a new mascot.I wish they had put something from the station (other than the planned cargo) in its place for the trip home.
Apologies if this is answered elsewhere as I haven't reviewed all 57 pages, but I'm curious about the aluminum-ish-looking blanking plate or cover that seems to be installed where I'd expect to see the Draco thrusters for the abort system. Is this a cover that will be ejected or is it a blanking plate for aero purposes that will be replaced with real installed Dracos in the next (crewed) increment, or .. something else?

Is this a cover that will be ejected or is it a blanking plate for aero purposes that will be replaced with real installed Dracos in the next (crewed) increment, or .. something else?It’s just a reflective seal coating over the thermal protection material (PICA-X?) to keep water out of it. The bottom heatshield has the same coating. There are working Draco’s and SuperDracos on this capsule. The SuperDracos ports have a film over them that is blown off the first time they are used. Draco’s has the same. Check the pre-launch pictures as compared to on-orbit pictures, and you’ll see what I mean.
Latest article says there will be a Draco burn to physically separate from the IDA. Was that necessary for similar ports(APAS-95, etc) or is this unique to crew dragon and the SpaceX Docking System?
