The Hubble Space Telescope (HST) has operated continuously since 1990. During that time, four space shuttle-based service missions were launched, three of which added major observational capabilities. A fifth â€" SM-4 â€" was intended to replace key telescope systems and install two new instruments. The loss of the space shuttle Columbia, however, resulted in a decision by NASA not to pursue the SM-4 mission leading to a likely end of Hubble's useful life in 2007-2008. This situation resulted in an unprecedented outcry from scientists and the public. As a result, NASA began to explore and develop a robotic servicing mission; and Congress directed NASA to request a study from the National Research Council (NRC) of the robotic and shuttle servicing options for extending the life of Hubble. This report presents an assessment of those two options. It provides an examination of the contributions made by Hubble and those likely as the result of a servicing mission, and a comparative analysis of the potential risk of the two options for servicing Hubble. The study concludes that the Shuttle option would be the most effective one for prolonging Hubble's productive life.

In a world obsessed with the virtual, tangible things are once again making history. Tangible Things invites readers to look closely at the things around them, ordinary things like the food on their plate and extraordinary things like the transit of planets across the sky. It argues that almost any material thing, when examined closely, can be a link between present and past. The authors of this book pulled an astonishing array of materials out of storage--from a pencil manufactured by Henry David Thoreau to a bracelet made from iridescent beetles--in a wide range of Harvard University collections to mount an innovative exhibition alongside a new general education course. The exhibition challenged the rigid distinctions between history, anthropology, science, and the arts. It showed that object-centered inquiry inevitably leads to a questioning of categories within and beyond history. Tangible Things is both an introduction to the range and scope of Harvard's remarkable collections and an invitation to reassess collections of all sorts, including those that reside in the bottom drawers or attics of people's houses. It interrogates the nineteenth-century categories that still divide art museums from science museums and historical collections from anthropological displays and that assume history is made only from written documents. Although it builds on a larger discussion among specialists, it makes its arguments through case studies, hoping to simultaneously entertain and inspire. The twenty case studies take us from the Galapagos Islands to India and from a third-century Egyptian papyrus fragment to a board game based on the twentieth-century comic strip "Dagwood and Blondie." A companion website catalogs the more than two hundred objects in the original exhibition and suggests ways in which the principles outlined in the book might change the way people understand the tangible things that surround them.
