Thanks I really miss seeing them come in over Seattle as they did during Mir mission reentries. I talked to a shuttle orbit "designer" at JPL just after the Mir missions ended. He said their primary concern was the crew sleep cycles which were on Moscow time for Mir missions. They did some night, descending pass, landings then. I guess it all depends on which factors carry the most weight. I can see how night landings would present more concerns but they did them in the past so you wonder how they set the priorities.

This was their response...If something were to happen during re-entry, they must rely only on their infrared cameras. During a day landing, they can use both the infrared and the visual tracking systems. Also, in the case of a catastrophic event, recovery efforts could be hampered by the dark night sky. ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
