Mars?maybe...
methane outbursts
see lunine et al. (2010) white paper
asteroids, comets, etc?yes
comet vs circumstellar disk
see lunine et al. (2010) white paper
Jupiter?probably only with MIRI MRS/IFU
Jupiter’s moons?maybe…
Saturn?probably only with MIRI MRS/IFU
Saturn’s moon, esp Titan?maybe…
Titan spectra
see lunine et al. (2010) white paper
Uranus?Yes!
Uranus spectra
Uranus – take it to the limits
Uranus Longitude-Resolved Spitzer SpectraComparison of 4 longitudes vs. mean of all four reveals variation in hydrocarbons
To what spatial feature does this correspond?
CH4
C2H6
