Settling Mars has been a hot topic for years due to its close proximity and the similarities it shares with Earth like an atmosphere and water. Even NASA has set its sights on sending humans to Mars some time in the 2030s.
However, spaceflight is expensive, and getting people to a different world will carry a heavy price tag. Plus, if we’re able to send people to Mars, they’ll need tools and a place to stay. Sending such things over in a spacecraft would only add to the cost (by quite a bit, too).
