Hostile environment or a place we can call home in a long-term perspective?

Compared to the Earth, the available living room in outer space is quite a bit larger. But outer space is about as hostile an environment as envirionments goes. Or is it? If we want to make space flights to the planets, or even further, the travel times will be substantially longer than any manned space flight before. So do the astronauts die of homesickness or begin to call outer space their home? And maybe some people just want to live in a place that is less crowded than on Earth, with its still growing population?

On the panel is science fiction writer Alastair Reynolds, space psychology expert Jesper Jørgensen and futurologist Klaus Æ. Mogensen. Moderator is Flemming Rasch, science + fiction fan.
