Living on a mothership in Earth’s orbit would likely be safer than living on Mars in terms of immediate survival needs such as food, water and oxygen. A mothership would have the advantage of being able to resupply from Earth and having better communication with Earth. However, living on a mothership would also come with its own set of challenges such as the long-term effects of living in space and the potential for collisions with space debris.

In contrast, living on Mars would have the advantage of being on a planet with a surface and potentially the ability to produce food and water through terraforming. However, the harsh conditions of the Martian environment and the lack of infrastructure would make it much more difficult to survive on the planet.

Ultimately, the decision of whether living on a mothership in orbit or Mars would be safer would depend on the specific circumstances and the level of technology and resources available.
