Two remarkable ladies with links to Arizona have their eyes set on the moon.

Chris Birch, a native of Mesa and University of Arizona alum, is one of NASA’s newest astronauts. Eleven other candidates for astronauts, including Jessica Wittner, a fellow University of Arizona alum, are present with her.

Both women received official astronaut status on Tuesday at a graduation ceremony held at the Johnson Space Center in Houston. This means that they are now eligible to travel to the International Space Station and, eventually, the moon and Mars.
