2. Science Frontiers More Thanks: NASA, ESA & CSA (for everything)
Northrop Grumman (for the telescope & the dinner!)
Instrument Teams
Speakers, 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 meeting
Technical progress is impressive!
Mirrors
Instruments are nearly built
Cryo tests are showing excellent performance so far
Challenges are inevitable
If it weren’t a stretch we wouldn’t be doing it
The international partnership is fundamental
Wouldn’t have started without it
Will not survive without it
¾ 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 disks
Gravitational effects
Chemistry and transport of water and organics
Find a molten proto-earth afterglow?
Study known exoplanets
Orbital constraints
Direct imaging
Sizes, atmospheres & thermal structure from transits & eclipses
Tricky 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 lensing
Challenging to confirm
Search for the first galaxies
How do we know we have found them?
Lack of [OIII]? Strong HeII?
Use strong lensing (50 or so) to
constrain dark-matter substructure
test density profiles
dissect AGN

8. The Extragalactic Background: Are we missing something?
Bock et al. 2006
At 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 neutrinos
Disentangle AGN and star-formation
Study the galaxy feedback cycle
Demographics of star formation & stellar mass vs. morphology redshift & environment
Evolution of Black-hole vs. bulge mass relation
Kinematics & abundances from spectra
Dust formation and destruction
H2 formation and destruction
Dissect tidal disruption events
A dime a dozen by the time of JWST

10. What history teaches us
Known unknowns
Detectors will have problems
There will be unforeseen problems on orbit
An essential component deep inside JWST will fail on a different mission before JWST launches.
Budgets & plans will lag behind reality
The fact that you should have known will be obvious in retrospect
Unknown unknowns
How the detectors will fail
What the technical glitches will be
When a tornado will disrupt a test schedule
What Congress will decide to do at any given time

11. What history teaches us
Known unknowns
Astronomers aren’t very good at making predictions
Also aren’t very good at posing answerable questions
Science won’t stand still
There will be surprise discoveries before & after launch
Observers will want to use JWST in unexpected ways
We will end up ignorant at a much deeper level
Unknown unknowns
Which predictions are wrong
Which questions are ill posed
What the surprises will be
What 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 planets
Make robust predictions
Make JWST scientifically efficient
Help STScI plan for realistic observing strategies
Communicate & coordinate
Mix of GO, GTO, Legacy projects is important
High fidelity simulations
Help design/develop the next generation of analysis tools
