The Washington Post article Boeing faces a significant setback with the spacecraft it is designing to fly NASA astronauts includes the following statemt:
The leak is likely to delay its launch schedule and is another setback for a program that has faced a number of problems. The trouble also comes as Vice President Pence is expected to announce the crews for the first missions during a ceremony in early August at the Kennedy Space Center in Florida.
Is it certain that the vice president will announce the names of astronauts in each crew, and if so, is it certain what the mission, or even the launch vehicle and capsule will be? I'd thought there were two different, competing commercial crew projects. Will one crew be trained for multiple launch vehicles, or will there be different crews trained separately for each commercial effort?
