Top 10 Major Risks in Space TravelstyLIShT Space exploration is risky, but that didn't stop us humans from venturing out into space. Here are the risks involved in space exploration.
The Top Ten
Astronauts are exposed to approximately 50-2,000 millisieverts (mSv) while on six-month-duration missions to the International Space Station (ISS), the moon and beyond. The risk of cancer caused by ionizing radiation is well documented at radiation doses beginning at 50 mSv and above. - styLIShT
You're being exposed to 5-G force during takeoff, there's a high risk of blackout during that period. - styLIShT
This happened on February 1, 2003, the Space Shuttle Columbia disintegrated upon reentering Earth's atmosphere, killing all seven crew members - styLIShT
This is a relatively huge risk during spacewalk, and the ISS (International Space Station) has had a considerable share of damage due to meteors hitting its vulnerable parts. - styLIShT
Moon dust is dangerous. Each mote is like a tiny shard of glas - there's no wind or rain to soften the edges of lunar soil. During the Apollo missions, it jammed equipment and got stuck in the seals of space suits, causing a serious loss of pressure. - styLIShT
Although this has a low probability, this is still a huge risk that astronauts face, considering the immense consequences. - styLIShT
Especially the helmet - you wouldn't wanna get that damaged. - styLIShT
The musculo-skeletal system allows the human body to physically move and exert forces on its environment.
Whereas on Earth the musculo-skeletal system has to support the weight of the body, and the postural bones and muscles are permanently loaded by gravity, this is not the case in weightlessness â€" in space, all physical activities are less demanding, the musculo-skeletal system is unloaded.
As a result exposure to microgravity leads to bone and muscle loss. - styLIShT
Would you eat the vomit if the rocket if vertical? - iliekpiez
During launch, you feel up to 3-g for a sustained period of time, which is beyond extreme, causing and aggravating motion sickness.
In space, thereâ€™s 0-g from freefalling around Earth, and thereâ€™s no up or down reference, so all of thatâ€™ll cause and seriously aggravate motion sickness.
Itâ€™s been known that even those who didnâ€™t have motion sickness before may still get it during space travel.
And the astronauts may still experience it for a while even after theyâ€™re back on Earth. - Gregory
Some astronauts have developed serious, permanent vision problems from their time in space. The longer the mission, the greater the chance of change. Of the 300 US astronauts examined since 1989, vision problems developed in 29 percent of those on two-week missions and 60 percent of those who spent several months on the International Space Station.
Doctors at the University of Texas performed brain scans on 27 astronauts whoâ€™d been in space for over a month. In over 25 percent of them, the back of one or both eyes had flattened.
Scientists believe this may be another effect of the rise of fluid that occurs in a personâ€™s body in a weightless, or microgravity, environment.
Some Russian cosmonauts and other astronauts have experienced partial to permant deafness during space travel. - styLIShT
This is a very low possibility, but if it happens, you're pretty much doomed. - styLIShT
