    Makes sense.

    1. Create a massive rocket
    2. Burn a massive amount of rocket fuel to get it into space
    3. Surround the comet ice in enough artificially made heat resistant materials so it doesn’t burn up in the atmosphere
    4. Use more rocket fuel to angle the giant ball of ice so it doesn’t burn up on re-entry
    5. Burn some more fuel to slow down its descent once inside the atmosphere so it doesn’t crash into the earth, ending all life in the immediate area
    6. Drop the ball of unsalted ice in the ocean

      Fun fact, the kinetic energy a comet would gain from falling into the Earth’s gravity well is around 60MJ/kg, more than two orders of magnitude greater than the energy which would be absorbed by it melting (0.33MJ/kg).
