They reach 15 times the background level before the increase. Doses inside the shuttle increase even more rapidly because of the hardening of the event spectra. The crew goes to the docking module for additional protection during the five polar cap passes that impart the most exposure. The dose rate has continued to increase slowly but remains low as measured by the on-board dosimeters being monitored on the ground by mission control. The EVA is completed 30 minutes early and the crew returns immediately to the spacecraft.
Reentry is still as scheduled, the next morning.
Advanced Shock Propagation Model, which predicts shock arrival time and post-shock parameters. Advanced Profile Forecast Model, which predicts flux profiles as the event proceeds for a standard set of energies. Version 3.0 Neural Net Fluence Model, which predicts integrated fluence for the event. Advanced Polar Cap Model, which specifies energetic particle access zones from predicted post-shock and CME conditions. All of these models, which have been given descriptive hypothetical names, are in various stages of development.
