Who attaches the Orion Docking Adapter to the ISS?

Someone eventually figured out it would be simpler just to make a LIDS to CBM adapter and cut out the middleman, hence CDA. It replaces both ATLAS and the PMAs. Out of curiosity, what is wrong with APAS and in what way will CDA be better ? |

ATLAS has been replaced by CDA. ATLAS stood for APAS To LIDS Adapter System. The APAS was mounted on the PMAs, which themselves were really just APAS to CBM adapters. Am I the only person who thinks that in the future we will speak and write entirly in acronyms? :-D LMPO Pat |

Out of curiosity, what is wrong with APAS and in what way will CDA be better ? See my last remark. You know, I'm getting fairly good at the acronyms...but still, all I can think of them is these lines out of Shakespeare's "Julius Caesar" every time I run into them around two or three times in a single sentence: "But those that understood him smiled at one another and shook their heads; but, for mine own part, it was Greek to me." :-D Pat |

Someone eventually figured out it would be simpler just to make a LIDS to CBM adapter and cut out the middleman, hence CDA. It replaces both ATLAS and the PMAs. CDA is thin enough to fit in the unpressurized compartment of an HTV and will be installed via the SSRMS on Node 2 forward and zenith. Two HTV flights will deliver the two CDAs. The PMAs will be moved to unused CBMs for storage.

Thanks Pat. Once again my ignorance is on display. I was aware of the Dragon automated cargo capacity, sheesh some memory I have, but not Cygnus. I've noted that many people here like to downplay Dragon, but very few people even mention Cygnus. Considering Cygnus is based on a long existing satellite bus, I've got high expectations for their first flight.

Yeah, but they also have to get their Taurus II rocket to work, just like SpaceX's Falcon 9. Pat |

True, but they've got quite a bit of historical experience in this area, where SpaceX is seen as a "start-up" with arguably less experience. This is despite the fact that the only true experience you have is in people's heads, and SpaceX no doubt has some seasoned engineers on staff. A comparison of people to people between the two organizations would be practically impossible.
