NASA astronaut Karen Nyberg from Vining, Minn. is making final preparations for her six-month trip to space.
Nyberg is one of three astronauts returning to the International Space Station to conduct hundreds of scientific experiments. KARE 11 reports one study will look at how space affects astronauts' bones and eyesight.
After completing training in Star City, Russia, Nyberg will liftoff on May 28 from the Baikonur Cosmodrome in Kazakhstan.
Nyberg was also aboard the shuttle Discovery in 2008.
She tells WCCO that the hardest part about the mission is being away from her family. Nyberg is married to fellow astronaut Douglas Hurley and they have a 3-year-old son together.
