Abstract Space weathering refers to alteration that occurs in the space environment with
time. Lunar samples, and to some extent meteorites, have provided a benchmark for …

Theory and observations point to the occurrence of magma ponds or oceans in the early
evolution of terrestrial planets and in many early-accreting planetesimals. The apparent …

ABSTRACT NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft has been brought
out of hibernation and has resumed surveying the sky at 3.4 and 4.6 μm. The scientific …

Meteoroids can be observed at collision with the Earth's atmosphere as meteors. Different
methods of observing meteors are presented: besides the traditional counts of individual …

Accumulation of dust and ice particles into planetesimals is an important step in the planet
formation process. Planetesimals are the seeds of both terrestrial planets and the solid cores …
