Methane in the Uranian atmosphere absorbs the red wavelengths of sunlight, giving the planet its blue-green colour. Planetary data for Uranus *Time required for the planet to return to the same position in the sky relative to the Sun as seen from Earth. **Calculated for the altitude at...
support of this recommendation, we present community-supported science questions, key measurements, and a suggested instrument suite that focuses on the exploration and characterization of the Uranian atmosphere by anin situprobe. The scope of these science questions encompasses the origin, evolution, a...

This "phase reddening" is not completely expected for a spectrally flat object: we suggest that the decreased importance of multiple scattering cannot be the entire explanation for more sharply peaked blue phase curves. The observations have been fit to the radiative transfer model of B. Hapke (...
The relatively blue, near-infrared dark surface of Miranda (full-disk near-infrared albedo of 0.22 at 2.4° phase angle) exhibits the greatest water ice absorption band-depth and the largest H- and K-filter brightness surge measured among the uranian satellites, consistent with (1) a markedly...
In ager images, the heavily cratered regions external to the reddish coronae were found to be relatively blue (Buratti 90, =-=Buratti and Mosher 1991-=-). Subsequent ground-based tions (Buratti et al. 1992) revealed a strong opposition brightness at optical wavelengths indicative of a “...
