AGENDA DETAILS: F2F5 Agenda 20170602.docx

 team building activities:  

   June 13, 7pm Nats-Braves Baseball game

   Possible visit to the National Museum of African American Culture and History.

Notional agenda items (please propose items of discussion at f2f):


  1. Interim report outline, schedule, tasks and chapter lead identification. Report ~ due Dec 2017, ~80 pages, HQ has said use EXO-C and EXO-S reports as guides:
    see https://exoplanets.nasa.gov/stdt/Exo-C_InterimReport.pdf  https://exoplanets.nasa.gov/stdt/Exo-S_InterimReport.pdf

       This was discussed at STDT telecon on Friday April 21st. Will need 2-3 hour discussion at the June f2f to finalize.

          40 pages sciences, 40 pages technical details of the baseline design.

     Executive summary: 2 pages (Asantha/Margaret - aimed at all stakeholders, very general)

     Introduction:  3 pages  (more science focussed,  Dave?)

     Science cases: 5 pages each from 6 WGs (WG leads) - 5 pages with figures, a table summarizing main science goals. focus first on top 14 proposals then add in the rest in a half page.

     Science requirements: synthesize all science requirements to a top-level table (STM) and some summary text (2 pages, Johannes?)


      Technical contents (~40 pages; should be coordinated through MCWG)

     2.  Second design trades and process.  This needs to be a 3 hour open discussion, small presentations expected from interested parties including JPL that will be making a proposal to the full STDT.

8:00 AM - 5 pm MDT Thursday 3rd

All times local

Remote connection will be available. IPAC to provide webex connection.

Room will have  large screens; also there will be two additional rooms for breakout sessions.

Wednesday Nov 2nd:

8:00 AM  breakfast (Ruth to confirm)

8:30 AM - 8:45 AM      Chairs Welcome

8:45 AM - 9:15 AM      Ball Welcome, Ball interests on the study. (Bill Purcell (Ball) - 30 mins, to introduce Ball heritage and interests in OST)

9:15 AM - 9:30 AM   Science group charge  (finalize science requirements, fill missing requirements info including sciences missing) - Asantha/Margaret

9:30 AM  - 10:30 AM  3 breakout sessions   (take a break in between)   (led by SWG leads)

Questions to ask within the group:   1.  Does everyone agree with the science tracebility matrix and results of the 14 proposal evaluation?  Are there missing science cases or requirements?

2. When you look at the science requirements,  discuss the flexibility of them; this understanding will be important for the interchange and negotiation with the engineering teams for the instrument designs.

3. The science tracibility matrix was created on the top 14 killer app proposals.  Look at the remaining proposals  (of the original 32 killer

        Missing cases: imaging mid-IR on all scales, spectral polarimetry, extragalactic polarimetry

      Wavelength vs spectral resolving power:   Wavelength-Spectral Resolving.pdf

        Session 1:  Extragalactic/Reionization

        Session 2:  MW/ISM/Local Galaxies:

               ** NEW cases: 1) evolved star case, 2)interaction of stars and ISM (shocks, outflows OI, CII, high-J CO, PDR lines). 

                   Capabilities should already be covered in STM.

              ** These science cases are covered in the current STM and can be part of our overview presentations:

                         1: stochastic accretion, 2: multiphase ism, 4: water transport, 5: galaxy feedback to z=1, 6: obscured AGN, 7: B fields, turbulence

               ** Need to include these features:

                        for case 1 (protostellar variability) - 1) shallow, fast imaging AND  2)~10% or better calibration accuracy,

                        for ALL MW - 3) high spectral resolution (already included, but is not flexible).

                        ** Need to make sure 1 and 2 are added to STM

Questions for Jonathan Hohman, JSC related to Johnson Test Chamber:


(Due to scheduling conflicts, we are going to have Eric Smith's JWST talk during a regular STDT telecon on a Friday) 

Questions for Eric Smith, JWST related to  all things we want to know about JWST and its history and cost (including cost overruns):

  1. from Charles L:  

    I understand that JWST will have observing efficiiency of 50% at best, and I've heard of fixed staring observations in several bands that come out in the high 30% range.  How did JW "achieve" this horrible inefficiency, and what could a future FarIR mission do to prevent the same thing happening again.?

    (Just for reference, Spitzer's observing efficiency (time collecting photons/wall clock time) over 90%.)
  2. from Anel Flores:
    1. My understanding is that JWST was funded at $5 Billion at Confirmation, and the presumption is that that amount includes cost reserves, say 25 to 30%, is that right? The mission is now estimated to cost $8 to $8.7 Billion, hence, what are principal reasons for the higher mission costs?

    2. What are the major lessons learned in the development of the observatory, and what would the JWST team do differently (if it was able to do all over again)?

    3. The observatory uses a composite ISIM, but there are unconfirmed reports of issues with the adhesives and confirmed reports of problems in attaching the heat straps to the composite structure. Based on these problems, would the team have selected another material, such as an aluminum alloy for the ISIM? What were the principal drivers for selecting the composite material for the ISIM structure?

    4. How did the JWST solve the problems of heat sources on the telescope side of the observatory.

  3. from Asantha:
        a.  Will it be possible to provide a breakdown of the total cost of JWST to subcomponents to the extent possible, including OTA, instruments, I&T, labor & overhead, launch, operations, etc?
        b.  In addition to historical record of JWST cost increases (and reasons for such increases), it would be also useful to know which items in particular had the highest cost increases since the initial estimate (and an estimate of that increase since some initial stage of the design).
       c.  JWST requirement is 5 years of operations but expectation is it will be operable for 10 years. Please comment on the reasons why the JWST team is confident of this 10-year operation lifetime.
       d.  OST is interested in implementing active mirror technology, possibly leading to certain mirror alignment and wave-front corrections in orbit. It is generally believed that such an adoption may reduced the burden on I&T and thus reduce overall I&T costs of OST. Given the JWST experience, to what extent such an approach could be a cost saving in a future mission development?
      e.   Which components of JWST had the highest risk rating or lowest TRLs at Phase A? Which required the most involvement from industry for development? What new components/approaches in the JWST design at Phase A, especially those that were deemed low TRL/high risk at the time of an early mission definition study, were later recognized as items that had been developed already by industries as proprietary work but not known to the definition team?
  4. From Dave:
    1. What are the mission success criteria for JWST?
    2. What thoughts (tradeoff considerations) went into the decision that JWST's instruments are not intended to be replaced by a second generation of instruments?

Eric Smith attended our STDT telecon on 16 December 2016. Here are his answers to the questions posed above. The JWST mission success criteria are given in this Level 1 Science Requirements document.

Other things:

  1. The hotel (Holiday Inn, Greenbelt, Maryland) has a shuttle, and it can serve as a means of transportation to/from Goddard (~10 min drive, allowing for traffic signals), but sharing rides with people who have rental cars will likely be more convenient and efficient, as I’m sure the shuttle, with limited seating capacity, would have to make several round trips if everyone on the team depended on this mode of transportation.

  2. Goddard has ample parking space adjacent to the building in which we’ll be meeting.

  3. On May 12, visitors will have to stop at the security office at the Goddard main gate to pick up their badges.
