'One Stop Before Mars' suggests a conceptual idea of having a 'fuel depot' or 'gas station' on space, that will allow spaceships to make a stop to recharge on space. This will make our future travel to Mars or from Mars [same for other planets] more economic, sustainable and safe for the return travel back home.

This project is solving the Create Your Own Asteroid Mission challenge.


For the idea of having a Stop before Mars and after Mars, we have created two tools:

  1. An Asteroid Calculator, which enable us to find the best asteroids to be converted into energy, and which position is the closest to the Mars orbit.

  2. A 'Space Limpet Energy Converter' is a solar powered robot, that can sustainably convert rocks of the chosen asteroids into fuel. Like the nature design of the limpet's teeth, the robot's augers situated at the bottom surface will create friction to the surface of the rocky asteroids and with the heat system, the dust will evaporate, eventually some cold fingers will turn the vapor into water, after separating the H2 and O2 and store them in separation, we can finally transfer it into the spacecraft as fuel.
