NASA and HERA:
The next frontier:
Hera. Speak her name and most think of the infamous Greek goddess and wife of Zeus; but now thousands of years after ancient Greece, her name has a new meaning. Meet the HERA X and her crew.
One of the four would-be astronauts is Lt. Cmdr. Oscar Mathews. He explained what it's like to live in the HERA module for 30 days straight without ever leaving Earth.
"It's the minimum amount of space four people can occupy and still stay sane over the course of a month, a year or three years," said Mathews. "A day starts around 0700. And mission control usually plays a short track of music and it really helps motivate us, just like they do for the International Space Station, so that's a tradition they do."
