Is a one-way Mars trip as fair as old no-return voyages?
Research question: How do ethicists compare the consent of a one-way Mars crew with the consent given by people who sailed or settled on expeditions where a return was never guaranteed?
The available facts cover each side separately but offer no direct ethical comparison between the two groups 123. The Franklin expedition of 1845 was one from which its members never returned, so the men who joined it did so without any guaranteed return 1. For Mars, a 2022 analysis notes that an astronaut may be unable to end participation, because distances and planetary alignment might make a return outside the planned window impossible 2. The same 2022 authors argue that astronaut candidates, after selection and training, are difficult to claim unaware of spaceflight risks, so they can be regarded as consenting to them 3. The newest fact is from 2022, about four years before October 2026.
