This Aquanaut Is Defining the Next Era of Spaceflight

Megan McArthur has spent her life messing with microgravity. She was on the team that got the first commercial cargo mission to the International Space Station. She's watched her friends launch in a Soyuz rocket from Kazakhstan. And as a NASA aerospace engineer, she was the flight engineer on the space shuttle's last mission to repair the Hubble Telescope. For Earthlings stuck here in 1G, getting to operate a robotic arm that wrangles Hubble into an airlock might seem like enough excitement for a lifetime.
