Can a crew Dragon dock with a CST-100?
Yes, I know that their docking mechanisms are different, but both are IDSS (International Docking System Standard) compliant. However, what I don't know is if IDSS compliant systems can dock with each other. Does anyone here know?
I'm wondering if something like an Apollo-Soyuz Test Project mission is possible, except a docking adapter would not be required, or would it?
Also this would be useful for an on-orbit rescue if one vehicle or the other was rendered inoperable.
