Seems to me he misunderstands the mission for Orion - it is to provide a stand by rescue/return docked to the station, so it does need long term endurance.

Also, what happens to the commercial craft when ISS is eventually deorbited.... by 2020 Node1/Zarya will be over twenty years old and couldn't go on for ever,yet you will have a transportation system utterly dependent on the station for any mission objectives?
In the first calendar quarter of 2010, Blue Origin performed detailed planning for the project, performed design activities to accomplish project objectives, ordered long-lead material from vendors, and prepared a kick-off meeting for NASA project management staff. This kick-off meeting occurred in the first week of the second calendar quarter of 2010.
CCDev program progressing as planned. Completed first 11 SAA milestones on or ahead of schedule (30% of program milestones) and conducted a successful SRR with numerous comments on the rapid maturity of the existing design during this quarter. Demonstration tasks kicked off and are progressing well, and several significant procurements placed. One demo task has potential for later schedule impacts due to delayed procurements that are currently being assessed. System Development Plan - Completed SRR products package and kick off review completed. RID acceptance period closed and RID closure and closure plans prepared for RID review board. Abort System Hardware Demonstration - Issued UCA to initiate Aerojet work while contract development is completed. Long lead material purchases have been issued by Aerojet. CM Pressure Shell Demonstration - Test requirements defined & coordinated with test facility. Test article design complete. Material procurements initiated . Developed process plans and fabrication details to support production readiness review. Completed and released data sets for all fabricated components. Completed finite element structural analysis. Developed initial pressure and structural test setups. Completed design review at Parker Seal in San Diego. Initiated procurement for all machined parts.
An internal Kick-Off Meeting was held on 2/12/10. The signed SAA and Amendment 1 were received on 2/19/10. On 3/1/10 Paragon requested that NASA waive rights to inventions made under the SAA to Paragon. Long-lead item procurement times for the Engineering Development Unit (EDU) were identified on 2/24/10. A detailed ECLSS driving requirements questionnaire was generated and submitted to 8 vehicle developers, 3 of which are current CCDev SAA partners. Six completed surveys were returned and 4 follow-up meetings were conducted. Design and Development Books for all subsystems and the top-level assembly were created to record development through PDR and EDU testing. A meeting with NASA was held on 3/9/10 to discus various topics (e.g. project status, Commercial Advisory Team utilization, intellectual property rights, human rating certification, NASA input to driving requirements, etc.) The following deliverables were completed as part of the Customer Requirements Review (CRR): 1-Concept of Operations, 2-System Specification, 3-Interface Requirements Document (included in System Spec), 4-Draft Subsystem Specifications, 5-Draft Human Rating Certification Package. These were submitted to NASA for review on 3/24/10. The content of the IRD was included in the System Specification. Paragon conducted our CRR on 3/31/10 at our Tucson, AZ facility with NASA representative in attendance. To complete the milestone, actions were levied to breakout the Interface Requirements as a separate document and update the other program documents with input received from NASA. The final CRR data package was delivered to NASA on 4/7/10 to close out the milestone. Overall project completion (measured as % completed) is 29%. The System Design Review (SDR) is scheduled to start 4/19/10. Work continues in the next quarter to mature the design and produce SDR and PDR data products. EDU development continues with procurement of additional long lead items and test facility preparations.
The Sierra Nevada Corporation (SNC) Commercial Crew Development (CCDev) program got off to a good start in the 1st quarter of 2010. The program was started by SNC conducting an internal team kickoff meeting held at the SNC facility in Louisville, CO. This was followed by an external kickoff meeting held with the key team companies. On March 18, a Program Implementation Plan Review was conducted with NASA at SNC?s Louisville facility. This review successfully completed the 1st Milestone for the program. All of SNC?s external team members were put under initial Letters of Contract in the 1st quarter. Finalization of these contracts will occur in the 2nd quarter. Initial SOW?s are in place for all SNC external team members. These will also be finalized in the 2nd quarter. Work has started in all task areas under the CCDev Space Act Agreement. In addition, SNC Louisville, CO facility modifications were started to allow expansion of the SNC CCDev team. Employment offers were extended and accepted by several engineers to fill new CCDev staff positions, and transfers were initiated for some SNC personnel to move to the Louisville site.
On March 19, 2010, ULA received the signed copy of the NASA authorized Space Act Agreement Amendment 1 that provided the program with direction to commence work on the subject SAA. NASA authorized the period of performance through December 2010. ULA held a successful kickoff on the 25th of March, which included material to meet the Milestone 1: EDS Demonstration Project Kick-off Meeting Success Criteria: Conduct Kickoff to Present Program Expectations, Program Plan & Identify Staffing Resources. As such, we submitted our first notification for completion of Milestone 1 (of 4) for NASA to approve. EDS Demonstration: Development of the requirements for the prototype testbed for the Emergency Detection System (EDS) for the Commercial Crew Development program is underway, including development of the process for selection of the preliminary set of prototype demonstration candidates. Additional candidates are being pursued through solicitation of input from the various potential crew spacecraft providers including Sierra Nevada, Boeing, Lockheed Martin, Blue Origin, HMX, and Orbital. In addition we asked them to identify any unique situations that maybe of interest for one or two more scenarios demonstration within the SIL capability as currently configured. We are also solicited top level interface requirements using a process similar to development of the Standard Interface Specification developed under EELV. This effort may culminate in a working session with the potential SC providers to negotiate the interface requirements for the potential crewed spacecraft configurations.
Anyone have any idea how many of the CCDEV alternatives would fit on which boosters or is it too early to say?
First, what are the CCDEV alternatives ?
Quote from: Jim on 05/12/2010 11:30 amFirst, what are the CCDEV alternatives ?This is one of the big problems I've notice on threads on this particular issue (and related ones of crewed space access). What the heck do we call this? As Jim points out, CCDev is basically a subsidy program for developing various systems. COTS-D is in a kind of implementational purgatory and doesn't really relate to the proposed commercial crew launch program at all. What do you call this?FWIW, I usually call it 'CCT' - 'Commercial Crew Transport'. However, that isn't a formal name so I usually have to define it the first time that I use it in a post.
Anyone have any idea how many of the CCDEV alternatives would fit on which boosters or is it too early to say?For example, SpaceX Dragon isn't in the CCDEV but the F9 LV will more than likely be available by the end of the CCDEV program. Are any of the alternatives slated for the F9 or other LVs?Cheers

The Commercial Crew Transportation RFI was released today, along with the document for the Commercial Human-Rating Plan::http://nspires.nasaprs.com/external/solicitations/solicitations.do?method=init&stack=pushhttp://nspires.nasaprs.com/external/solicitations/summary.do?method=init&solId={85357053-E659-E2DE-C7AE-BB14600C2E96}&path=init(the Exploration Precursor Robotic Missions RFI also came out today)
In a multiphase strategy, the program would help to spur the innovation and development of new spacecraft and launch vehicles...
