Shes paying the mortgage or the rent the same amount regardless of whether or not you are there. You are not a causitive factor in her inability to manage her finances other than she likely guilt trips you into constant loans. Cut it off now before it gets any worse. She needs to sink or swim.

Easy. Tell mom you aren't going to lend her your money that you earned anymore. She's an adult right? Shes had a long enough life to learn how to be an adult, dont you find out odd she cant handle money and has to rely on her son?

Nothing wrong with being cautious on spending, provided you are actually increasing savings each month and not lending it all to family or whatever it's a good attribute to have. Id stop the money lending prompto.

Not really. NASA and Roscosmos are still regularly working together in the same way they always have. They were all together at an event in Russia recently.
