Most crew members also develop vision problems upon return because of the effects of micro-gravity
, which causes pressure to build up in the optic nerve.
"...We are witnessing the dawn of a new industry that will change the way we live life here on Earth." Robust and reliable access to micro-gravity
will impact fields as diverse as pharmaceutical development to fuel production, representing a broad and substantial technological leap forward.
Scientists have yet to offer a definitive explanation of why space causes the seeds to mutate but they believe that cosmic radiation, micro-gravity
and magnetic fields may play a part.
Its presence will boost crew safety by reducing the number of hours that astronauts will have to be outside the station on spacewalks, and thus allowing them to focus on other tasks such as conducting scientific experiments in micro-gravity
, according to the Canadian Space Agency.
When an astronaut is in a micro-gravity
environment--for example, doing a spacewalk outside the International Space Station--working in such a massive suit is manageable, Newman said.
The space station allows scientists to conduct experiments in extremely low gravity, or micro-gravity
We even had a Glasgow University experiment on board about reflexes in micro-gravity
He provides a sketch of what the space tourism industry might look like in the near future, describing such possible activities including brief orbital jaunts, stays in space station hotels, micro-gravity
gymnastics, and moon buggy tours.
The picture in the lower middle section is a group our students who have for the last three or four years participated in the Alabama Space Grant Consortium project on micro-gravity
The EU/ESA high-level group on space policy met on June 4 for the first time to discuss the various elements of a European space programme (science and space technology, Earth observation, space navigation, satellite telecommunications, space exploration, micro-gravity
, launchers and spectrum policy related to space).
