Why did they even install the IDA on the ISS PMA docking ports?
as far as i know, the ports that were in place before the IDA were installed were 100% androgynous so they could dock to anything that has the same port so no need for active/inactive or male/female sides, which the IDA now has by utilising active on the visiting spacecraft and inactive on the PMA port. I’m sorry if my expression of the question was kind of unclear because english isn’t my first language #space source
