The National Academy of Sciences will reassess a decision by NASA Administrator Sean O'Keefe to cancel a final servicing mission to the Hubble Space Telescope and also examine other non-shuttle related Hubble life-extension moves. That reassessment is coming in the wake of a Senate subcommittee request for a more narrowly focused shuttle servicing study-which O'Keefe rejected- and a judgment by Columbia Accident Investigation Board Chairman Harold Gehman, that O'Keefe's earlier decision may not necessarily be an open-and-shut case. After appearing before NASA's Senate appropriations subcommittee, O'Keefe said that even if the Academy offers a positive assessment on shuttle servicing, he is unlikely to change his mind about the Hubble mission cancellation because of shuttle risk.
