Agenda:
Update on management of WG and mailing lists (Shaul)
UMN physics listserv is retiring, so future working group mailing lists will be done through Google Groups: Shaul has already done this for extragalactic, data challenge, and imager. Some bugs have been found. Shaul can set this up for other WGs if needed.
Technology Working Group and Plan (McMahon)
Roger put together a review of relevant technologies:
Slides here Roger is technology person at JPL. Jeff and Roger plan to have offline discussion with different groups around the country - get them to augment what they have provided to S4 tech book with any material relevant to a space mission. Jeff following up with NIST, Berkeley, GSFC folks; Roger to check in with McGill, Brad Johnson, Charles Lawrence, Peter Day.
The Inflation Probe should address some specific questions quickly: e.g., what detector technology to use above 800GHz? Power dissipation? How to get a community consensus on these questions? Use S4 as a starting point, solicit input from teams working on these individual technologies, present this information again to the EC.
In the spirit of transparency, need an opportunity for some back-and-forth: perhaps a open review by telecon for Roger and Jeff to present their results and get feedback.
Keep in mind that this is a current snapshot showing we have a solid case fitting in the cost cap, not a formal technology selection - were this mission to fly 10-15 years from now it is likely to look very different technologically. But important to have some baseline technology selection.
Update on NASA management of probes and expected deliverables (Shaul)
-
Entire slide package is also available on the wiki.
Study report is ~50 pages.
Engineering Concept Definition Package: prepared by JPL. This is only submitted to the decadal panel on request. Primary use is for the Independent Cost Estimate.
Can we find out what tools/models will be used by SOMA (the independent cost estimators) ? Shaul will ask. JPL has a number of models that can be used to check variance.
Independent Cost Estimate does not include pre-phase A technology maturation costs, but we should be careful about including too many low maturity technologies to avoid large cost penalties.
