For Cycle 9 the Science Program Selection Office (SPSO) has changed the selection process to ensure that HST will continue to perform the best possible science with the best return for the astronomical community. This report summarizes the changes to the selection process and offers suggestions on writing an effective proposal that accounts for these changes. ... Fewer panels: With more orbits to allocate, each panel will have more flexibility, especially to approve the somewhat larger proposals. ...
