NASA scientists are developing rocket fuel made from Martian soil
Scientists at NASA are currently developing methane-creating robots to overcome this challenge.
- It's a problem that NASA scientists are working on because the weight of the fuel it would take to travel both to and from the Red Planet is immense.
- What they're proposing now would actually gather fuel from water in the Mars soil.
- Once that's extracted, then it's fairly simple to separate out hydrogen. When that is combined with carbon from the atmosphere ... Voila! Methane.
Scientists at NASA are working on a bit of alchemy that would greatly improve the chances of a mission headed there of actually returning. Otherwise, we'd have one of those desperately sad situations like in old science fiction movies where astronauts are simply stuck on the planet with no way to return.
The problem is this: Hauling fuel to Mars so that the return flight back to Earth actually succeeds is not just inefficient, but it would also take up a ton of precious cargo space. In order to solve this dilemma, NASA is currently working on utilizing solutions that are already on the planet itself.
One possible idea is to turn water from Martian soil, known as "regolith" (as is any topsoil and rock layer on any planetary body) into its components, hydrogen and oxygen. Then, once that is accomplished, combine carbon from Mars' atmosphere with hydrogen, creating... methane!
Fuel from regolith?
The robot that will do this, known as RASSOR (Regolith Advanced Surface Systems Operations Robot), is shown below in testing, and it illustrates how the surface material will be converted for use both as rocket fuel and as energy for inhabitants of a colony on such a planet. The idea is to send the robots to the planet long before humans arrive so that the methane would be stored up and ready to use.

"This technology will one day allow humans to live and work on Mars," said NASA Team Lead Kurt Leucht, "and return to Earth to tell the story."
Political activism may get people invested in politics, and affect urgently needed change, but it comes at the expense of tolerance and healthy democratic norms.
