As experts continue to analyze a possible conjunction with debris from a portion of an Ariane 5 rocket body, NASA space shuttle CAPCOM Tony Antonelli informed Discovery and International Space Station crew members that the options have been narrowed to two: either not performing a Debris Avoidance Maneuver at all; or performing a reboost avoidance maneuver after Thursday’s second spacewalk. There no longer is any consideration being given to deboosting the shuttle and station, which would have delayed the second spacewalk by a day.
