  3. The instrument will work on a process called solid oxide electrolysis.
  4. The net reaction becomes,     2 CO2 ——> 2CO + O2
  5. NASA officials stated that if this prototype worked efficiently, they could land a 100 time larger MOXIE based instrument on Mars.
  6. The liquid oxygen made by MOXIE could supply more than 75% of the propellant humans need for exploration.
