Speckle Imaging of Titan's Surface
We are engaged in an ongoing project to map the surface of
Saturn's moon Titan using speckle interferometry on the
Keck I telescope. The surface of Titan is hidden at visible
wavelengths by a thick, hazy atmosphere. Observing at
wavelengths longward of 1 micron, however, it is possible
to penetrate this haze. The technique of speckle
interferometry used on a 10-m telescope allows us to achieve
a resolution of 0.05 arcseconds at 2 microns, or 300 km at
Titan's distance. Maps in 3 near-infrared bands (J, H, and K')
will allow us to constrain compositional variations.
