2 Science Frontiers More Thanks: NASA, ESA & CSA (for everything) Northrop Grumman (for the telescope & the dinner!)Instrument TeamsSpeakers, Poster presenters, session chairs and lively participants!
3 Sobering Wisdom from Norman Augustine Law XXXIX: Most programs start out slowly and then sort of taper off.
4 We can’t afford to be complacent! Science is exciting!This meetingTechnical progress is impressive!MirrorsInstruments are nearly builtCryo tests are showing excellent performance so farChallenges are inevitableIf it weren’t a stretch we wouldn’t be doing itThe international partnership is fundamentalWouldn’t have started without itWill not survive without it¾ of the focal plane relies on it!
5 A few more of Augustine’s Laws XXVII: There are only three kinds of programs which suffer incessant budget tampering: those which are behind schedule, those which are on schedule, and those which used to be ahead of schedule.XXV: The only thing more costly than stretching the schedule of an established program is accelerating it.XIV: If a sufficient number of management layers are superimposed on top of each other, it can be assured that disaster is not left to chance.
6 If JWST launched tomorrow, we have great ideas What causes the rotational modulation of the spectrum of Uranus?Why is Neptune’s stratosphere hotter than Uranus’s?Observe solar systems forming from proto-planetary disksGravitational effectsChemistry and transport of water and organicsFind a molten proto-earth afterglow?Study known exoplanetsOrbital constraintsDirect imagingSizes, atmospheres & thermal structure from transits & eclipsesTricky observing strategy decisions – need to prioritize what to do early
7 More great ideas Can we find Pop III Pair-Instability Supernovae? May need help from lensingChallenging to confirmSearch for the first galaxiesHow do we know we have found them?Lack of [OIII]? Strong HeII?Use strong lensing (50 or so) toconstrain dark-matter substructuretest density profilesdissect AGN
8 The Extragalactic Background: Are we missing something? Bock et al. 2006At face value, the integrated extragalactic background light suggests a major source of energy in the near-IR- early energetic galaxy formation?- bad subtraction of zodiacal foreground?
9 More great ideas Measure H0 to 1.3% (JWST+GAIA) To constrain Dark Energy and neutrinosDisentangle AGN and star-formationStudy the galaxy feedback cycleDemographics of star formation & stellar mass vs. morphology redshift & environmentEvolution of Black-hole vs. bulge mass relationKinematics & abundances from spectraDust formation and destructionH2 formation and destructionDissect tidal disruption eventsA dime a dozen by the time of JWST
10 What history teaches us Known unknownsDetectors will have problemsThere will be unforeseen problems on orbitAn essential component deep inside JWST will fail on a different mission before JWST launches.Budgets & plans will lag behind realityThe fact that you should have known will be obvious in retrospectUnknown unknownsHow the detectors will failWhat the technical glitches will beWhen a tornado will disrupt a test scheduleWhat Congress will decide to do at any given time
11 What history teaches us Known unknownsAstronomers aren’t very good at making predictionsAlso aren’t very good at posing answerable questionsScience won’t stand stillThere will be surprise discoveries before & after launchObservers will want to use JWST in unexpected waysWe will end up ignorant at a much deeper levelUnknown unknownsWhich predictions are wrongWhich questions are ill posedWhat the surprises will beWhat the new observing modes will be
12 1980s: There should be a bright early epoch of galaxy formation Where’s the kaboom? There was supposed to be an earth-shattering kaboom!
13 Homework for Astronomers Find targets:strong lenses, high-z QSOs, transiting planetsMake robust predictionsMake JWST scientifically efficientHelp STScI plan for realistic observing strategiesCommunicate & coordinateMix of GO, GTO, Legacy projects is importantHigh fidelity simulationsHelp design/develop the next generation of analysis tools
