CAPE CANAVERAL, Fla. (AP) — NASA has replaced an astronaut assigned to Boeing's first launch with a crew.

Astronaut Eric Boe was pulled Tuesday from the upcoming test flight for unspecified medical reasons, after more than three years of training. Taking his seat will be Mike Fincke, a former space station commander.
