The James Webb Space Telescope (Webb) is the largest space telescope realized to-date, with a 6.5 m segmented primary mirror that must be folded to fit within its Ariane 5 launcher fairing. This infrared telescope is passively cooled using a five-lay

The formation of water ice on key thermal and optical surfaces is a factor in the design of the James Webb Space Telescope. Many of these concerns are related to the mid-infrared stray light performance of the system. In this paper, an expression for

The James Webb Telescope (JWST) is a large cryo-optical system. Many critical thermal control or optical surfaces are exposed to ground and flight environments and are expected to be contaminated to some level. In order to calculate key system perfor

Disconnection events (DEs) from Halley's comet are analyzed as a group (in order to minimize the impact of uncertainties in any single event) for correlation with solar-wind features. This analysis utilizes new coronal source-surface model results an

The disconnection event (DE) in the plasma tail of Comet Halley on January 9-12, 1986 is examined. The distances between the comet head and the disconnected tail are measured for a series of images for that time period and then extrapolated to the nu
