HST MSR News

Yesterday was the HST MSR, and while there was little news, there is a little controversy brewing.

COS and WFC3 are making progress toward being flight ready, though in the case of WFC3 they have some very odd things they need to deal with. The oddest is that they seem to have some kind of small particulate contamination on the inner window of one of the detectors. The particles show up in images, but aren’t visible in a microscope.

Both teams are now thinking about what support they will need to be flight-ready on the data processing side. Both teams need support for Thermal Vacuum, Servicing Mission Ground Tests, and an Integrated Pipeline Test. Both teams would also like a separate test of association processing. None of the tests seem terribly challenging, though some of the WFC3 world coordinate systems work looks somewhat difficult.

The problem is, as the WFC3 team suggested, that the OPUS people are mostly working on Kepler, and the DADS people are mostly working on HLA. That leaves very limited resources available to support any changes needed (either prior to or as a result of these tests) to OPUS and DADS until some time in May. Since the tests are all scheduled to be done by sometime in March, that’s a problem.

You all know we’re in the process of trying to find somebody to work on OPUS, and later on Calibration (what I’m now calling the Calibration Products Team, since the acronym is available) to provide a longer-term solution to this problem. However, we need to figure out some kind of short-term option. Mike Hauser suggested that if nothing else, we’d need to move resources back from Kepler to address the HST issues.

Anyway, there will be several followup meetings to understand the schedule, to understand which tests really need to be done early, and who might be able to help out, either from within ESS or from elsewhere inside or outside the Institute.

More news on this will certainly be forthcoming.
