I was wondering if you could put the Pressurized Cargo Module (PCM) for Cygnus in the Dragon Trunk?The PCM for Cygnus has a diameter of 3.07m and a height that looks to be about 2.4m. The dry mass is 1,500kg including the service module I think, so maybe just 750kg for the PCM?Dragon has a diameter of 3.7m and CRS-8 is carrying BEAM in the trunk and BEAM has a 3.2m diameter (although this likely is less for transport) and 4m height and is 1,360kg.It seems like it would fit to me. Thoughts?

Thoughts?No.A. the Dragon can not maneuver with itb. The PCM is not made to be pulled into orbitc. Trunk does not the structural capabilityd. No performance to carry it
Who are "those folks"?

After all, they are cutthroat competition, not in milion years or something.

Not saying it would fit in the trunk or anything like that, but ISTM F9E has quite a lot of performance in reserve when it lifts Dragon. Cheers, Martin

Cheers, MartinThe limitation would not be the payload capacity of Falcon 9 it would be the payload capacity of Dragon. According to wikipedia Dragon has a maximum payload of 3310kg. The dry mass of Cygnus would be included in this total mass.Edited for clarity.

Is (1) wrong or lack of performance or lack of incentives or short time scales or what?
