Asteroid Chaser

Asteroid Chaser is designed to travel from Moon to Mars with an energy efficient way.

The middle section is the control center, its radars detect nearby asteroids and uses robotic arms to catch them.  If the asteroid are moving in the same direction towards Mars, this spaceship will hitchhike along. For other asteroids, the lower compartment can extract minerals and convert into energy. 

The space garden provides food and oxygen for the astronauts. The front cockpit can be detached and land on a planet. There is also a smiley face design at the bottom of the spaceship to show our friendliness to any lifeforms they might encounter.
