Abstract
This article examines some selected ethical issues in human space missions including human missions to Mars, particularly the idea of a space refuge, the scientific value of space exploration, and the possibility of human gene editing for deep-space travel. Each of these issues may be used either to support or to criticize human space missions. We conclude that while these issues are complex and context-dependent, there appear to be no overwhelming obstacles such as cost effectiveness, threats to human life or protection of pristine space objects, to sending humans to space and to colonize space. The article argues for the rationality of the idea of a space refuge and the defensibility of the idea of human enhancement applied to future deep-space astronauts.

Notes
Because Mars is the most probable destination for the future human space missions, when we discuss the issue of human space missions, we have in mind mostly missions to Mars. We discuss the significance of Mars, rather than other planets or our Moon, below.
It is evident that a space refuge must be a very expensive project. For more arguments on that financial side of the idea of space refuge, and political, social and economic challenges for a public budget policy, see Szocik (2019).
See the concept of the so-called disposable planet mentality in Schwartz (2019).
For more detailed discussion on possible catastrophes on Earth and their relation to the idea of space refuge, see Szocik (2019).
