IDA-2 is on PMA-2, and IDA-3 is on PMA-3. The numbers are nicely consistent.In one sense I'm glad this happened, otherwise we'd be talking about IDA-2 on PMA-3 and confusing ourselves on a regular basis.Quote from: Comga on 09/07/2020 09:09 pmAccording to Gunter's PMA-1 was lost on CRS-7,PMA-2 is on Node-2 Forward, andPMA-3 is on Node-2 ZenithOn the other hand that doesn't prevent us from confusing ourselves in other ways. You linked to Gunter's page on the IDAs but your post mentions the PMAs. It was IDA-1 that was lost, not PMA-1. PMA-1 links the US segment with the Russian segment.

After launch of Crew Dragon’s first operational mission with astronauts on board, SpaceX will launch its 21st cargo resupply mission to the ISS – the first to use the upgraded version of Dragon outfitted for cargo missions
Anybody thinks it is bigger than Crew Dragon? Some extension in the upper part? Or am I confusing the image because of the crane?
This might be too early to ask, but do we know what booster will be used for this flight?
The #BishopAirlock is....READY. We're packed up (again) and moving down the road for delivery to @SpaceX tomorrow. Next week, we begin procedures for installation in the #Dragon trunk!
Additional upcoming NASA missions rely on the Falcon 9 for launch. The Sentinel-6 Michael Freilich launch still is targeted for Tuesday, Nov. 10, from Vandenberg Air Force Base in California, and NASA's SpaceX CRS-21, is targeted for launch in late November or early December, from Cape Canaveral Air Force Station in Florida. NASA and SpaceX will use the data from the company's hardware testing and reviews to ensure these critical missions are carried out with the highest level of safety.
I don't see any more vestigial window features in either photo. That speaks to a thorough design upgrade from both the COTS Dragon 1 and the Crew Dragon. (I apologise if this is not strictly specific to the CRS-21 flight.)

This is much cleaner and looks more thought out. Agree, its clearly a different aeroshell (new door panel, new panel for areas next to door (to cover the windows), 4x panels for each of the pods) which most were not predicting. Why make them still with the superdraco humps / pods?This engineer choice has to be due to not wanting to develop a 2nd set of CFD models for takeoff. I can't imagine the reentry model still holds with the additional streamlining for the SD pods.
