    • Abstract:
      Verseux was one of six ersatz astronauts participating in HI-SEAS IV, a 2015 University of Hawai'i experiment. For now, NASA sends most of the astronauts' food from Earth and recycles waste with machines, but the space agency still uses biology "where it makes sense". NASA scientists are studying whether altering lignin production might help humans absorb more nutrients from their veggies or make it easier to deal with plant waste in space.
