  3. Please note there is a new rule regarding the posting of videos. It reads, "Post a summary of the videos you post . An exception can be made for music videos.". Unless you are simply sharing music, please post a summary, or the gist, of the video you wish to share.
  4. There have been some changes in the Life Stages section involving the following forums: Roaring 20s, Terrific Thirties, Fabulous Forties, and Golden Eagles. They are changed to Gen Z, Millennials, Gen X, and Golden Eagles will have a slight change.
  5. CF Staff, Angels and Ambassadors; ask that you join us in praying for the world in this difficult time, asking our Holy Father to stop the spread of the virus, and for healing of all affected.
  6. We are no longer allowing posts or threads that deny the existence of Covid-19. Members have lost loved ones to this virus and are grieving. As a Christian site, we do not need to add to the pain of the loss by allowing posts that deny the existence of the virus that killed their loved one. Future post denying the Covid-19 existence, calling it a hoax, will be addressed via the warning system.

lunar oxygen made available..?

    I think this is a major advantage toward not only making the moon habitable for astronauts, but even for potential Mars colonies.

    Approximately 45% of the weight of regolith is oxygen, but it is bonded to materials such as iron and titanium. To utilize both the oxygen and the materials it’s bonded to they must be separated. And a British company, with support from the European Space Agency, has begun testing a technique to judge its potential effectiveness on the moon.

    We teamed up with Faith Counseling. Can they help you today?

    Oxygen is rather common in space and is also Bound chemically in rock. That’s interesting if they can get it to work efficiently. The lower gravity is going to be a bigger problem IMHO

    Mars is slightly better in the gravity dapartment...

    If you are thinking of the oxygen flying out into space due to low gravity that is not much of a problem. The escape velocity from the surface of the Moon is about seven times the average velocity of oxygen at room temperature. It is the lack of a magnetic field that cost the Moon what little atmosphere that it had.

    Not really what I meant sorry for the confusion. Oxygen molecules are rather common in space not just on a rocky or icy surface

    Oxygen is plentiful in minerals. The problem is getting it out of those minerals. That takes quite a bit of energy and proper chemical reactions. Merely melting the rock will not do. I was thinking about it and thought that electrolysis was the only option and it turns out that is what they are planning to do according to the linked article. It might just work.
