There will be lots of different kinds of space vehicles,some examples;
- Rover / MiniRover / MegaRover
The Rover is basically a 'space-humvee/jeep'. The regular sized Rovers should have place for 2-4 people. The MiniRover should be a part of the Exploration Sattelites,and is remote-controlled. The MegaRover is basically a sort of 'space-bus'. Used to bring people on the Space Stations,Settlements or Colonies from the Residential Centers to the Work Centers,or for large-groups exploration.
- Buzzer / MiniBuzzer / MegaBuzzer
The Buzzer is a 'space-heli/jet',with place for 4-8 people,and a small compartment for some goods. The MiniBuzzer is also part of the Exploration Sattelites,and is remote-controlled. The MegaBuzzer is a larger one with room for some 25+ people.
- Dolphin / MiniDolphin
The Dolphin is a 'space-submarine',with room for some 10 people. There is also a MiniDolphin,remote controlled and part of Exploration Sattelites. They can withstand great deapths in water-oceans,but should also be able to dive into seas and oceans of liquid methane and other liquids.
- Transporter / MegaTransporter / MiniTransporter
The Transporter is a 'space-freighter'. The regular Transporter is used to deliver goods over relatively short distances (like Earth-Moon or Mars and its Moons). The MegaTransporter is for large distances,like Earth-Mars and interstellular. The MiniTransporter can retrieve resources from planets,moons and asteroids.
