Offerors are to consider their CTS lead time when inputting their data above. The CCtCap contract is anticipated to conclude at the end of 2020.
NASA has not downselected to anybody yet. That statement is your personal opinion and should be so labeled.

Quote from: clongton on 01/21/2014 12:04 amNASA has not downselected to anybody yet. That statement is your personal opinion and should be so labeled.I think maybe the term down-select is being tossed about too freely. Nit: NASA can not and will not down-select awardees for CCtCap. Under FAR, CCtCap is open to any qualified bidder, and not a down-select from a predefined field. That said, some culling of the field is likely given past and projected CCP funding constraints.The operative question is: Who gets selected to provide ISS crew services under CCtCap? In particular, will there be sufficient funds for 1, 2 or ...? Given a projected demand of two ISS crew missions per year, the justification for funding at least one provider seems clear; for two questionable; for three extremely dubious.Given that, it appears that there will be one front-runner who will be awarded sufficient funds to see CCtCap through to providing ISS crew services; and another awarded reduced funds which, while not sufficient to provide ISS crew services, provides a backup--or at least an incentive to the front-runner to keep their eye on the ball.
There is no backup. Each round is independent of each other. If NASA decides to have 1.5 providers for CCtCap, the 0.5 company also has a chance of winning the CTS award. But my point was that there will only be one CTS award. NASA has said so on a number of occasions. It's not set out in stone but that's the current plan.

NASA has said so on a number of occasions. It's not set out in stone but that's the current plan.Sorry should have been clearer as that was my point. Any such FAR acquisition (i.e, CTS) must be open to all qualified bidders, including those not selected for previous contracts (i.e., CCiCap and CCtCap).I don't recall NASA making any single-award statements with respect to CTS. NASA's notional timeline at the CCtCap pre-proposal conference appears to suggest otherwise, with new-entrant certification and competition for CTS possible in the future (much like NLS on-ramp for new entrants). What am I missing?
Gerst said so in a few hearings. I don't remember which one. I will try to find it. But just from a practical point of view, 2 flights per year makes it difficult to have more than once company.
Mr. PALAZZO. What is your estimated cost per flight once the development stage is completed?Mr. GERSTENMAIER. Again, we would look at it as equal to or less than what we would be paying for Soyuz at that time.Mr. PALAZZO. Some———Mr. GERSTENMAIER. Roughly $480 million or so.Mr. PALAZZO. How much would that come down per astronaut since that seems to be the common way of looking at it?Mr. GERSTENMAIER. Roughly $80 million per crew seat.Mr. PALAZZO. Okay.Mr. GERSTENMAIER. Six seats per year, $480 million total per year.
I found the document where Gerst says that commercial crew would cost $480M per year:http://www.gpo.gov/fdsys/pkg/CHRG-112hhrg70800/pdf/CHRG-112hhrg70800.pdfThat document from 2011 actually says that NASA might support more than one CTS provider. But I will see if I can find other more recent documents.
ISS Services ContractLikely single award
Mr. BROOKS. Thank you. And continuing, Mr. Gerstenmaier, at a rate of no more than two NASA missions per year, most analysts conclude that only one provider will ultimately be needed. If only one provider is selected to provide this service, how much government funding will have been provided to the other firms that will not be providing subsequent services to the United States government?Mr. GERSTENMAIER. If you want a precise number, I can take it for the record and we can go calculate what that number is, but there will be funds that will have gone to these other providers that are not providing a service. The question is, is the market going to be just ISS or is the market going to be bigger than ISS. What we hear from these commercial companies is they believe that there is a market for their spacecraft that is beyond the government’s need. They believe there is a commercial-sector market for that. So even though one of these companies may only provide services to NASA for our ISS activities, the others may have another market to go do that can be there. Then I have the advantage from the government side is now I have another contractor that I could go back and pick up to go provide services later in some future activity if we decide to extend, for example, space station beyond 2020 and we need some additional services. It may be someone else in the market for us to go by. So we are investing in that other contractor as you described but we potentially get some benefit if they can generate a market on their own.

But just from a practical point of view, 2 flights per year makes it difficult to have more than once company.That said, let's ensure we differentiate between CCtCap (including post-certification missions, which could run through 2020), and CTS.
Incidentally, I think that one of the reason for having post-certification missions is in order to provide incentives to the CCtCap company that doesn't obtain a CTS contract. I think that post-certification can not go beyond 5 years from the date of the award (August 2019). This change was made in the final RFP.
H.19 (a) Post Certification Mission (PCM) task orders may be awarded prior to completion of CLIN 001, DDTE/Certification. However, the Contractor shall meet the following development-related criteria before NASA will grant Authority to Proceed (ATP) with such missions. ATP for PCMs is at NASA’s sole discretion and is dependent on meeting the criteria. Specific mission objectives and target launch date are provided by NASA.
The maximum number of all PCMs awarded to all CCtCap contractors is six. To the extent that they do not overlap with the existing Soyuz contract, post-certification missions are expected to be used to rotate crews on the ISS. Ed Mango mentioned at the conference that post-certification missions can be ordered thru December 31, 2020 [now September 2019].
CCtCap is likely to have 1.5 or two providers. McAlister said that they are unlikely to maintain three providers for the next round but that NASA wants (if they have the budget for it) to keep competition going as long as possible which is why CCtCap is likely to have more than one provider. But the CTS contract (the contract for ferrying crew to the ISS which starts in 2017) is likely to have just one provider. At least, that is the current plan. I agree that there is an overlap between CTS and CCtCap and I believe that this was done on purpose in order to provide incentives for the company that doesn't win a CTS contract to continue.
So actually, then can come close to finishing out the decade without awarding a CTS contract. There might actually be incentive for a company to remain in the CCtCap program as an "unfunded" if there is the possibility of funded post-certification flights.
That's a good question and I am not certain about the answer. My understanding is that NASA has the option of either ordering post-certification missions (PCM) from both providers (assuming that there is two) or not order any. See clauses B.4, H.8 and H.19 in the second document linked below. More specifically, under H.19, NASA appears to have the discretion to proceed or not with PCMs (i.e., the authority to proceed seems discretionary) but if they do proceed with PCMs, each provider must be considered for a minimum of 2 flights (See B.4). http://forum.nasaspaceflight.com/index.php?topic=32412.msg1121659#msg1121659
In accordance with clause C.1, Specification/Statement of Work, the task ordering procedures and other terms and conditions in the contract, the Contracting Officer may issue Post Certification Mission (PCM) task orders.
Correct, we can finish the decade without CTS; based on the notional schedule, CTS flights will not start until late CY2019 (FY2020), even though the notional CTS award is in 2017. IMHO the CTS contract* will likely be pushed back.As to remaining in CCtCap unfunded, see above. CCtCap currently requires that every awardee complete DDT&E/certification and is guaranteed a minimum of two post-certification missions. If you get that far you're done, and the next step is missions paid for under CTS.
CCP is also assessing alternatives to mitigate transition timing between Phase 2 Certification and ISS Services (contracts). One approach being considered is to potentially include multiple postcertification mission(s) within the scope of the Phase 2 contract. The Government is considering these post-certification mission(s) to be optional (e.g. IDIQ or contract options); awarded at the Government’s discretion and based on Contractor performance. The mission(s) would be defined as the CCT-DRM-1110 of a certified configuration. During Phase 2 contract performance, flight specific objectives for optional mission(s) could be tailored to fit Agency requirements. The post-certification optional missions are expected to be licensed by the FAA for public safety.
s far as PCMs, B-4 of the RFP document uses the word "may" which implies that it is not automatic:QuoteIn accordance with clause C.1, Specification/Statement of Work, the task ordering procedures and other terms and conditions in the contract, the Contracting Officer may issue Post Certification Mission (PCM) task orders.
There is an overlap between CTS and CCtCap according to page 14 of this presentation. The chart also confirms that PCMs are optional and that they are there to provide incentives:
See the following document which is even clearer on this issue (page 3):https://prod.nais.nasa.gov/eps/eps_data/155325-OTHER-001-001.pdf
The winning (CCtCap) bidder will be awarded at least two missions, which gives them an assurance that they will recover some of their investment.
