NASA bumped an astronaut off so close to launch. Astronaut Jeanette Epps was going to fly away in early June. She would have been the first African American to live in the Space Station. NASA announced that they were pulling her off the mission but didn't say why. "She will be put on missions in the future" says NASA. She was replaced by her backup, Serena Aunon-Chancellor, a doctor. Epps is returning to Houston from Russia. NASA spokeswoman said it was a decision by NASA, not the Russian Space Agency.
