About NASA Return to Flight Mission:
The Columbia Accident Investigation Board (CAIB) Report has provided NASA with a roadmap “to resume our journey into space.” The recommendations “reflect the Board’s strong support for return to flight at the earliest date consistent with the overriding objective of safety.” NASA fully accepts the Board’s findings and will comply with its recommendations.
To do this, the NASA Implementation Plan for Return to Flight and Beyond outlines the path that NASA will take to respond to the CAIB Report. It is a “living document” that is continually updated to record NASA’s progress toward safe return to flight as well as activities to institutionalize the technical, managerial, cultural, communications, and safety changes necessary to sustain safe flight operations for as long as the Space Shuttle’s unique capabilities are needed.
Recommendations identified as return to flight by the CAIB or NASA must be completed before resuming Space Shuttle flight operations.

"More than a year ago, we set out a specific plan for Return to Flight with specific milestones. Right now, those milestones are pointing us toward a new launch window," said William Readdy, NASA's associate administrator for Space Operations. "I am proud of our Shuttle team for taking good care of our orbiters during this terrible storm season. I am pleased they are taking the time to make a careful assessment of the hurricanes' impact. Their thoroughness will help us make the right decision," he said.

During this year's Atlantic hurricane season, four storms affected four NASA facilities in the southeastern United States. Thankfully, no workers were injured and no spacecraft or hardware damaged. However, Hurricanes Charley, Frances, and Jeanne closed down NASA's Kennedy Space Center, Fla., for approximately nine days and damaged several facilities. Hurricane Ivan caused shorter closures at NASA's Stennis Space Center, Miss.; Marshall Space Flight Center, Huntsville, Ala.; and the Michoud Assembly Facility, New Orleans. Many NASA workers and contractors are still coping with damage to their homes and other impacts on their families.

NASA's Space Flight Leadership Council is co-chaired by Readdy and Walter Cantrell, deputy chief engineer for the Independent Technical Authority. The council also includes the directors for NASA's four space operations centers; Chief Officer for Safety and Mission Assurance Bryan O'Connor; and Deputy Associate Administrator for International Space Station and Space Shuttle Programs, Michael Kostelnik.
