Prevent me from going mad. The NASA update I had this morning stated that Dragon had carried all 6 iROSAs !

Quote
.....Dragon launched June 3 on a SpaceX Falcon 9 rocket from Launch Complex 39A at Kennedy, arriving at the station a little less than 16 hours later. The spacecraft delivered more than 7,300 pounds of research investigations, crew supplies, and vehicle hardware to the orbiting outpost. Dragon’s external cargo “trunk” carried six new ISS Roll-Out Solar Arrays (iROSAs),.......

This is wrong - there are just 2 going up this time........?

I suspect that either the person writing the press release misspelled two or that there were some words missing (perhaps: the first two of the ).

My question is about the supports (mounts), not the solar panels.
The first 2 supports came with Cygnus 15. What about the next ones ? With Cygnus 16 for august EVA ?

Next solar array delivery is on SpX-26 (from Joel Montalbano at SpX-23 press conference)

The iROSAs for the 1A and 1B power channels are scheduled to be launched in the trunk of SpX-28 on June 3rd with 1A being installed on June 9th and 1B being installed on June 15th

This is the first time I'm hearing there will be iROSAs for the 2A and 3B power channels

Launches Seen: Atlas V OA-7, Falcon 9 Starlink 6-4, Falcon 9 CRS-28,

Why not make last two arrays transformational

As that would require a new design to be certified for flight, NASA had signed a contract with Boeing for 6 iROSAs that included an option for an additional two. Certifying a new design is more expensive and take more time so NASA went with the option to order two additional iROSAs as it meets their power requirements for the ISS

Plus ground spares.

i didn't understood your point. Irosa will be used as the baseline just swapping solar cells (different) and adding reflectors i am fairly familiar that iss needs proves tech most of the time. But this is an old proven nasa tech. This was tested on dart spacecraft's rosas. The screenshot in previous post shows darts tsas.
