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...

Out of this world – NASA’s textile technicians and innovations for space voyages
... space without special textiles to provide protection from low gravity, radiation and the extremes of heat and cold. Here...space, everything works differently than on Earth due to the low gravity environment. Sweat, for example, tends to stay on the ...

Most precise test of Einstein’s general relativity outside Milky Way
...We then compared these two ways to measure the strength of gravity — and the result was just what general relativity predicts, ... Einstein’s theory is the leading theory to explain how gravity works on a Universal scale and it has withstood vigorous...

Simulating space in a bathtub
... have shown that weightlessness causes one’s body to become ‘de-trained’ - that is to lose its ability to properly react to gravity. In order to solve many applied and fundamental issues relating to this problem, scientists have to develop zero...
