  1. ... mass and volume acquired during the June 11 flyby give Phoebe a bulk density of ~1.6 g/cc, consistent with a mix of rock, ice, and organic material. Craters cover the moon and range from 100 km diameter down to resolution limits (~50 m). Landslides have exposed bright patches of nearly pure water ice ...
  2. ... dust. Small amounts of secondary minerals (clay, carbonate, sulfate, halide) in martian meteorites formed by reaction with subsurface fluids. Gusev Crater rocks analyzed by Spirit are picritic basalts, having compositions distinct from TES surface units but similar mineral compositions. These rocks ...
  3. ... abundance of plant groups (Vajda et al. 2001). New Zealand, located in high south latitudes at the time of impact and far from the Chixculub crater site, provides an invaluable opportunity to test the global effects of the bolide impact on ecosystem biodiversity. Nichols, D.J. & Johnson, K.R., 2003 ...
  4. ... -ductile transition of ~22 km. Because diurnal stressing was important when Triton began to circularize its orbit (not too long after capture) and crater density indicates the surface is young, capture must be relatively recent (i.e., within the last billion years) if diurnal stresses are an important ...
  5. ... Lost River fault. Holocene basalts, some about 2,100 years old, crop out along the southeastern edge of the quadrangle.
