STS-300 lead time (CSCS)?

• STS-300 lead time (CSCS)? by psloss on 12 Jan, 2006 22:40
• I've seen a few recent posts here that 40 days is the latest that Atlantis could get off on an STS-300 mission for contingency shuttle crew support (CSCS); does anyone know the source for that number?  Is that based on a recent estimate of ISS consummables plus the expected logistics that 121 will bring up?
  
  The reason I'm wondering is that the duration is very close to the one reported prior to STS-114 and just wanted to know if the number is based on the pre-114 estimates or a more recent estimate.
  
  Thanks,

• It'll be dependent on ISS logistics and I doubt anyone will truely know until a month or so before 114. It is around 40 as an estimate.

• I haven't looked to see if the STS-121 b/u crew rescue flight STS-301 has the same requirements as STS-300 did but it should have a minimum launch readiness capability of around 33-35 days.  
  
  If you want to know the rational for this capability you might look at the copy of the STS-300 Flight Requirements Document (page 1 summarizes it pretty much in a couple of sentences).  NASAWATCH.COM/SPACEREF.COM posted a copy for the public to veiw prior to STS-114 at the following link:

  If I get a chance to look at the 301 requirements in the near future, I will post them here if someone else doesn't do it first.

• Thanks. While I know you are aware, I just want to keep everyone with the right terms. The LON mission for STS-114 requirement is still STS-300.
  
  301 would only be if the 300 was used. Of course, that in terms means no 301 ever, as a resulting LOV ends all chances of further STS flights.

  There are 43 days between STS-121 (May 3) and STS-300 (June 15) launch dates, according to internal NASA's Flight Assignment Working Group (FAWG) Planning Manifest (October 19, 2005)...

  Thanks for all the replies to my question -- I appreciate it.
  
  Can I ask for further clarification on this?  How much margin is there with the 43 days, if any?
  
  Thanks again,

  Very good information to have. Thanks.

• Let's hope the Progress flight before STS-121 goes to plan otherwise this would turn into about 10-20 days I'd guess.
• #8 by Chris Bergin on 25 Jan, 2006 01:06
• And the information to answer the question of how long the window of the LON for CSCS is...
  
  As of time of post: 59 days (a lot more than everyone had thought).

• STS-300 CSCS to support a NET STS-121 of May 10 is a NET of Aug 4 - as per new manifest.
• #10 by Jamie Young on 08 Feb, 2006 02:03
• So that's nearly three months of CSCS time.
• #11 by SimonShuttle on 08 Feb, 2006 11:46
• I'm trying to add up the days, but not sure if I start from May 10 or May 3 on the CSCS?

  There are 86 days between STS-121 (May 10) and STS-300 (August 4) launch dates...

• This is going to get a review, as per conference today. All eyes on Thursday's PRCB meeting.
• #14 by Flightstar on 02 Mar, 2006 01:06
• There will be a re-assessed CSCS lead time from tomorrow's PRCB.

  I see the March 2 manifest is on L2, but any news of this issue you mention?
