In-Situ Resource Utilisation (ISRU)

Hello everyone!

As I see little activity in this Space Science Blog, let me start a new topic so that you can start discussing about something. The topic will be In-Situ Resource Utilisation, or just ISRU, and by now I'm pretty sure you know something about it. In a nutshell, ISRU involves the use and manipulation of extraterrestrial resources in the very astronomical object where they were obtained. So, for example, if some mineral is obtained in the Moon, use it, transform it, or whatever, in the Moon, without the need for bringing it back to Earth. However, ISRU expands way beyond this. Incredible things can be done with this technology.

My suggestion is that you answer to this topic with information about ISRU that deals with:
  • The technology to be used
  • The machines that can be used to do it
  • The materials, chemicals or other resources that can be obtained and what they could be used for
  • The astronomical body where it could be done
  • Any other idea that you may come up with

I'm sure you have already found information about it and I thus suggest that you share it as an answer to this post or even as a new topic. This way, other participants may learn things they didn't new and you will also learn from the information that other fellow participants will share. Trust me, you will see how useful and enriching this forum can be!

Kind regards ;)

Hello everybody!

It seems really interesting to me to start a new topic related to ISRU as, in my view, it is a key technique in the search for extraterrestrial resources for the following reason: as human space exploration goes further, it will become more and more important to generate life-sustaining elements (food, air, water, rocket propellants, spare parts for the spaceship, building materials…) in-situ because of the fact that resupply missions from Earth are incredibly expensive and inefficient as the resources need to be lifted from the Earth's gravity (while using ISRU don´t). In other words, it is far more viable, practical and affordable using space resources in-situ to sustain the crew and for space propulsion and power systems rather than carrying everything that is thought to be needed in the mission from Earth.

Such is the potential which the space industries have seen in In-Situ Resource Utilisation that an increasingly big number of ISRU projects are being developed nowadays. I will continue doing research into these projects and share with you what I learn!

Kind regards,
