Ready for Mars? From Mars-500 to zero-gravity medical issues
...Personal space will be very limited, radiation storm shelter provision relatively lightweight and there is no likelihood of artificial gravity being possible for these early flights. The physical challenges for the crews spending 12–18 months in zero...

Megasatellite habitat at Ceres
... be built using materials extracted from the Moon, and later from asteroids, to provide Earth-like 1g artificial gravity. However, the size of the cylinder is limited by mechanical constraints, so sooner or later several of them will be needed. With...

Investigations into plant growth on the Moon
... Moon would also have to contend with a very thin lunar atmosphere, radiation, bombardment and one-sixth gravity, all of which may not support germination, growth and development. It is impossible to mimic all of these conditions simultaneously...

The Space Elevator – an alternative path to space?
...”. Mother Earth, however, makes leaving hard! A combination of high total mass and density results in high surface gravity. We have tried to overcome this with chemical rockets, governed by Tsiolkovsky’s rocket equation [2] which relates the delta...

Towards a research roadmap for human reproduction beyond Earth
... as a species we survive there. Can people safely conceive children beyond Earth? How would pregnancy develop in reduced gravity? What effect would cosmic radiation have on embryos? Who decides the ethical boundaries of such research? If humanity...
