· Below is NASA’s answer to Hyperbola’s question about multiple efforts for docking systems that seemed to be springing up everywhere
As well as progress with the Orion crew exploration vehicle’s LIDS NASA has informed Hyperbola that $15 million is to be spent on docking system work for the agency’s commercial crew and cargo programme and last week the European Space Agency explained to this blog that it too was co-operating with NASA on a docking system that is called the Common Berthing and Docking Mechanism
“[Low Impact Docking System] is the baselined docking mechanism for Constellation/Orion.
· ISS has assumed responsibility for building a new docking adapter for the US [International Space Station segment]
o Replaces the existing Pressurized Mating Adapter (PMA) based [Androgynous Peripheral Assembly System (APAS)] docking system used for Shuttle
o ATLAS (remember that ATLAS stands for APAS to LIDS Adapter System) has been transferred from Orion to ISS and integrated into new project called Common Docking Adapter (CDA)
o CDA Project has been asked to develop a new International Docking Standard, which would identify key technical requirements that would allow many different designs for docking spacecraft. If an agreement can be reached and the agency implements the standard on ISS, LIDS may be slightly modified to interface with the standard [emphasis added].
· $15M in [American Recovery and Reinvestment Act 2009] funding is being used to develop requirements for a new docking adapter and building components for a demonstration International Docking Standard
