Generating water

  • The vehicle has been under development for the past three years.
  • It will be capable of carrying scientific instruments, the four small rovers, and also a future pressurized vehicle for humans. The goal is to land on the Moon’s south pole, where ice deposits were confirmed in 2018. Water can be exploited to produce hydrogen, which in turn could fuel future exploration of the solar Fully loaded with fuel, Blue Origin will weigh about 33,000 pounds (15,000 kilograms), which will decrease to around 7,000 pounds when it is about to land
