Worst Things About Space Travel

Space is magical, wondering, and getting us to learn new things out there.
But going to space is a challenge unlike any other, and it also has major downsides to you.

The Top Ten

1 Motion Sickness

It’s very common to experience motion sickness during space travel, and it is often a Very intense case with going to space.
When you launch on a rocket, the vibrations will shake you hard enough and continuiously that you could get whiplash, and possibly stroke, and also, the acceleration of launch produces g-forces that are extreme and intense, and it makes breathing pretty much impossible, and you feel the urge to vomit and go diarrhea, and your heartbeats and blood pressure are greatly affected.
When you’re in space, you feel 0-g, and you experience weightlessness, which would also cause motion sickness, and our blood rushes to our heads, and we even wouldn’t tell which way is up or down anymore, so we’d get VERY sick.
Side effects are nausea, headaches, dizziness and disorientation.
Even after returning back to Earth, you’d still experience motion sickness and it would take a long time to recover.

Great list. It's kinda spooky too if I give it some thought. It is and will continue to be a special breed of humanity that travels through space. They must be athletic, adventurous, intelligent and patient. Not to mention all the things I can't imagine. Humanity has come so far just to be able to where we are now as far as space exploration, it's truly the greatest accompaniment of our species I feel. I can only image the incredible feeling of what it must be like to look at the Earth from space. - Ned964

2 Heart Changing Shape

In space, without the adequate pressure or gravity, our hearts won’t be able to pump blood the right way, and cells are damaged.
The case is usually a smaller and rounded heart, and our heartbeats would be greatly affected and messed up.
The effect is usually irregular heartbeats. - Gregory

3 Whiplash

Owch... Hopefully the downsides of space travel will be conquered by the time of future technology when space travel becomes a normal thing in the far future.

I like Metallica though... - EliHbk

Rocket launches produce such powerful vibrations that they shake you uncontrollably you would end up to the point of whiplash or even stroke.

Our brains are surrounded by a skull with water inside, but the shaking is powerful and especially uncontrollable that it would put our brains at risk of deformation and contact with the skull, causing stroke.

You might not have a problem shaking your head as hard as possible because you’re in control of it, but you can’t control a rocket’s vibrations, so it messes you up.

More likely, sudden changes in motion, such as that, would mess up our bones and organs (and brain), leading to whiplash.

Astronauts are very brave and prepared. - Gregory

4 Loneliness

In space, you’re not able to see your friends or talk to them anymore.
You’re separated from them, and Earth, and it’s an example of being homeless and lonely. - Gregory

5 Cosmic Radiation

Space looks harmless, but there lies radiation in every corner, and exposure to ratiation destroys DNA cells and cancer, which can lead to death.
Our Sun, other stars, Supernovae, Hypernovae, Nautron Stars and Black Holes produce cosmic radiation, and enough of it is lethal. - Gregory

6 Space Junk

In space, there is debris everywhere, and especially around Earth, where we sent satellites up, and many accidental collisions destroy the satellites and create space junk.
We’re littering in space, and not to mention the pieces move at breakneck speeds much faster than bullets, meaning a tiny piece can damage structures and even kill you. - Gregory

7 Claustrophobia

Rockets are huge, but the insides, and the capsules, are very tight and confining, and those with claustrophobia need to think twice before riding.
You’re very crammed in and you can barely move around for adjustments or control. - Gregory

8 Different Sleeping Patterns

On Earth, we rotate so that our day is 23.93447117 hours, therefore we are awake during the day and working, and we’re asleep at night.
In space, there’s no 23.93447117 hour rotation, so we can’t tell when is day or night, and our sleeping patterns are different, and often messed up.
It’s a problem for our health and a big challenge involved in space travel. - Gregory

9 Stale Food

We eat very tasty food on Earth, but I. Space, the g-force is lower, and we feel congested, blocking our taste buds, making the food taste stale.
At least, healthy food gets the body going. - Gregory

10 The Distances to Destinations

Take all the other items on this list and line up behind this bad boy. It's the distances between objects in space, like Earth and say, Proxima Centauri, which at 4.37 light years away from our Sun, is our closest neighbor. Think about that for just a minute. We cannot yet travel at near light speed, not even close, but if we could, it would take 4.37 years just to reach our nearest neighbor. There are billions of stars in the Milky Way galaxy alone, and the nearest is that far away. So the next time your fantasizing about space travel, 1st dream up a vehicle that can travel at 186,000 miles per second (that's a little over 7 times around the Earth at the Equator, in 1 second) and 2nd, have that vehicle come equipped with room to hold 4+ years of supplies, have some way to counter-act the horrible effects on the human body living in a zero gravity environment, and lastly, develop some failsafes for any unforseen problems (for instance, what effect would it have on humans to travel al ...more - Ned964

The Contenders

11 Drinking is Harder

In space, the lower g and pressure means liquids would go out of control, or even vaporize.
Astronauts often drink through tubes to get the liquids in the right place, and that’s hard.
And since they don’t drink in space as often as they do on Earth, they end up getting dehydrated and that’s a problem. - Gregory

12 Re-entry

When your space mission is over, you re-enter Earth and go through it’s atmosphere, which has enough friction to burn an unprotected spacecraft.
On February 1, 2003, The Space Shuttle Columbia, (the 1st one ever launched) burned up and broke apart on re-entry (due to insulation foam breaking off), killing all 7 astronauts.
This shows us one of the reasons why space travel is not easy. - Gregory

13 Dehydration

Dehydration is a common problem for astronauts, as 1st being from adrenaline.
Since adrenaline heats up the body temperature and increases heart rate and blood pressure, the body produces more sweat, a water loss leading to dehydration.
2nd, the extreme g-forces drain the energy and water from the body, also producing extreme sweat, and so does vomiting.
3rd, from boiling of the moisture from the body due to microgravity, 4th from not drinking as much due to it being harder and the more frequent urination from microgravity, and then 5th from re-entry.
It's extremely important to stay hydrated, so astronauts have been finding ways to drink in space to stay hydrated during their missions. - Gregory

14 Muscle Loss

On Earth, we rely on gravity as a part of building our muscle strength, but in space, we can lose as much as 50% of our muscle mass, therefore astronauts have to exercise regularly as much as possible during missions, and even then they still aren’t normal like people on Earth.
Besides people on Earth with certain diseases, astronauts are among the weakest people. - Gregory
