Are there plans to attempt a flight day 1 docking with Mir?
For Shuttle-Mir missions to provide a 7-minute launch window on every day of the year the Shuttle must rendezvous on flight day 3 or flight day 4. So, for Shuttle-Mir missions there are no plans to rendezvous and dock on flight day 1. Flight day 1 rendezvous limits a launch opportunity to approximately once every third day.
