NASA and companies express growing confidence in commercial crew schedulesby Jeff Foust — July 21, 2017
NASA ASAP notes:Kathy Leuders and team doing great jobSchedule: SpaceX April 2018 uncrewed, August 2018 crewed. Boeing August 2018 uncrewed, November 2018 crewed.MMOD - something about purposely putting some defects on a cargo Dragon so they can inspect on return and refine the MMOD models???Both providers still doing parachute testing. SpaceX has several more tests to help reduce uncertainty in the models. Boeing added six tests (not all drop tests? something about a high mach test?) for parachutes. Boeing found issue with shock of parachute deployment during structural testing, being worked.NASA working on launch commit criteria, including weather/sea states for abort scenarios. Also looking at on-orbit MMOD inspections.Approval of the vehicles will occur at Associate Administrator or higher level.SpaceX continues development of the COPV 2.0. Some members of the panel visited SpaceX last month to discuss. NASA is still doing lots of analysis on COPV physics, something about NASA working on some alternative path for the COPVs.The Merlin turbine disc improvements have been implemented and are in the middle of testing. One of the panel members with propulsion experience had a chance to go over it with SpaceX. Referred to it as a bladed disc (blisc) in a single forging. It's a complex, state of the art forging.Boeing making progress on RD-180 certification, working through several unspecified design changes.
Take-away:- Both SpaceX demo missions have slipped two months in the past 3 months....Prediction: before the first quarter of 2018 is over it will have become clear that the SpaceX unmanned demo mission is the only CCP mission that will fly in 2018. All other demo missions will have slipped into 2019.
Suggest that there is less incentive to realize commercial crew launches from America, more reason to add ambiguity to commercial crew safety, and to artificially inflate program cost ... possibly to lessen the differences to other vehicle(s). Under constantly shifting goalposts.Poor leadership. From the usual source.

- NASA- Nefarious interests- political undercurrentsIt's never ever the contractors fault though.

The on-orbit MMOD inspections that NASA is proposing will only serve to delay CCP further. Those inspections will bring with them new requirements and new procedures to be implemented before the first manned missions lift-off.

As I understand it, this would just be using Canadarm and the crew photography equipment to take pictures of the outsides of the vehicles, same way they did/do for Shuttle and Soyuz and planned to for Orion CEV. No hardware changes needed for the vehicles, and the on-station work would be no different from any other Canadarm operations
Wrong. New requirement: perform multiple additional manoeuvres, in support of on-orbit inspections, in stead of straight- in approach. This in turn requires the development of a whole set of new additional procedures. Those don't come into existence overnight. They will take several months of additional time. Thus: delay.

Of course, inspecting it on the way in after it has been in space for less than 24 hours doesn't mean a whole lot when it won't get used for reentry until 6 months later.

Yes and no. There are 6 months to fix the capsule. The parts sent up on a later mission. If the capsule cannot be repaired a replacement can be sent to the spacestation.
