Each week of Down to Earth features a special online live event: Mission Control Live! These fun, interactive sessions are your chance to meet real experts and learn what it’s like to work in space science. In addition to working on her PhD, astrobiologist Emilie Lafleche is also an analog astronaut. What’s that? Analog astronauts simulate multi-week Lunar and Martian missions so scientists can research the effects on humans and test technology before it’s launched into space.
