Could Enceladus's Icy Plumes Pose A Hazard To Cassini? (8/30/2007)

On 12th March 2008, Cassini will swing by Saturn's moon Enceladus at an altitude of less than 100 kilometres at the point of closest approach. This will give scientists and unprecedented opportunity to study the plumes of water vapour emanating from the "tiger stripe" fissures near the moon's south pole, but it has also given the Cassini team pause for thought as to whether ice grains lofted by the jets could damage the spacecraft. ...> Full Article

Speeding Bullet Star Leaves Enormous Streak Across Sky (8/27/2007)

SMART-1 diagnoses wrinkles and excess weight on the Moon (8/24/2007)

Combining information from SMART-1 and Clementine makes it possible to assess the link between fine geological structures, identified for the first time with AMIE's high resolution, and the chemical composition of the study area. These fine geological structures form due to local mascon (mass concentration) or because of the thermal effects in the area related to volcanic activity. This deforms the crust giving it the appearance of being 'overweight' or 'wrinkled'. ...> Full Article
