Missouri Astronaut goes into space

America has launched four astronauts into space today, including the wife of a Missouri astronaut. 

The four-person crew is the first astronaut launch from U.S. soil this year. Piloting the shuttle Endeavor is Megan McArthur, the wife of St. Louis County native Bob Behnken.  

They have a 23-hour trip ahead of them to the International Space Station and are expected to parallel park around 4:10 a.m. Saturday.
