00:00in the relatively near future a lot of humans might find themselves on mars and while the
00:09journey to the red planet will no doubt be a long and arduous one when they land there there won't
00:13be a team on the other end to help them into wheelchairs and check their bios which is why
00:17a new study by researchers from anu college of health and medicine might change the way we think
00:22about mars with the researchers finding that the trip to mars and the time spent in microgravity
00:26might be the most dangerous part of the whole experience the first problem is radiation time
00:31spent outside of earth's protective atmosphere and magnetosphere means you're more exposed to
00:35radiation from space in addition being in space also affects not just your muscles but your bone
00:40density and your red blood cell count as well and they say that since it's easier for your heart to
00:45pump more blood in zero g it can cause the organ to weaken and this is the most difficult readjustment
00:49for astronauts coming down from the international space station and why they often faint upon return
00:54according to the researchers they also say that their goal is to create a better computer model
00:58which can take into account the health of individuals and pre-existing conditions and
01:02predict their ability to survive the trip to mars
