  4. Who was James Webb? NASA Administrator 1961 – 1968 Architect of the Apollo Program Strong supporter of science Initiated NASA’s space program: 75 space science missions flew during his tenure

  5. JWST white paper by Lunineet al. (2010) JWST Planetary Observations within the Solar System http://www.stsci.edu/jwst/doc-archive/white-papers/JWST_Solar_System.pdf

  6. Mercury? No.

  7. Venus? No.

  8. Earth? No.

  9. Mars? maybe...

  10. methane outbursts see lunine et al. (2010) white paper

  11. asteroids, comets, etc? yes

  12. comet vs circumstellar disk see lunine et al. (2010) white paper

  13. Jupiter? probably only with MIRI MRS/IFU

  14. Jupiter’s moons? maybe…

  15. Saturn? probably only with MIRI MRS/IFU

  16. Saturn’s moon, esp Titan? maybe…

  17. Titan spectra see lunine et al. (2010) white paper

  18. Uranus? Yes!

  19. Uranus spectra

  20. Uranus – take it to the limits

  21. Uranus Longitude-Resolved Spitzer Spectra Comparison of 4 longitudes vs. mean of all four reveals variation in hydrocarbons To what spatial feature does this correspond? CH4 C2H2 C2H6 S(1) H2 quadrupole
