>>98263261The spaceships will be ready in 30 years, so we just need to send some microbes to Mars to start terraforming it, which won't require a proper spaceship.
Things microbes can do:
>extract oxygen and nitrogen from rocks and release them into the atmosphere.>migrate magnetite to the pole to strengthen the magnetic field protecting the planet.>create a biome of running water with flora and fauna that the microbe's epigenetics transform it into once the environment is ready.In fact, we could just put humans on Mars without even building a spaceship to take humans there, but they'd be totally feral.
