The Cosmic Origins Spectrograph
The Cosmic Origins Spectrograph (COS) is a moderate-resolution spectrograph with unprecedented sensitivity that was installed into the Hubble Space Telescope (HST) in 2009 May, during HST ServicingExpand

The lunar atmosphere: History, status, current problems, and context
After decades of speculation and fruitless searches by observers, the lunar atmosphere was first observed by Apollo surface and orbital instruments beginning in 1971. With the end of Apollo missionsExpand

Collisional Erosion in the Primordial Edgeworth-Kuiper Belt and the Generation of the 30-50 AU Kuiper Gap
One of the oustanding questions about the architecture of the outer solar system is how the trans-Neptunian disk of comets and small planet-scale objects known as the solar system's Edgeworth-KuiperExpand

On the Collisional Environment, Accretion Time Scales, and Architecture of the Massive, Primordial Kuiper Belt.
ii Abstract Previous collisional modelling has suggested that the mass of the primordial Kuiper Disk between 30 and 50 AU was probably of order 10M to 50M. We explore the consequences of a massive,Expand

Photometric analysis of 1 Ceres and surface mapping from HST observations
The highest resolution (pixel scale 30 km) images of Ceres to date have been acquired by the Advanced Camera for Surveys onboard Hubble Space Telescope, through three wide band filters, centered atExpand

We present a new analysis of the currently available orbital elements for the known Kuiper belt objects. In the nonresonant, main Kuiper belt, we find a statistically significant relationship betweenExpand

Accretion in the Edgeworth-Kuiper Belt: Forming 100-1000 KM Radius Bodies at 30 AU and Beyond.
We employ a time-dependent collisional evolution code to study the conditions under which the 50{200 km radius Edgeworth-Kuiper Objects (EKOs) in the region between 30 and 50 AU (now called theExpand

The evolution of comets in the Oort cloud and Kuiper belt
Comets are remnants from the time when the outer planets formed, ∼4–4.5 billion years ago. They have been in storage since then in the Oort cloud and Kuiper belt—distant regions that are so cold andExpand
