Let’s do a hypothetical: A narcissistic billionaire who buys up social media networks, makes electric cars and also freaking rockets offers you a one-way ticket to his new Mars colony. The biggest factor in your decision might be the fact that you’d be leaving behind your home planet as well as everyone you’ve ever known for a cold and unforgiving desert rock. But even if you can conquer such homesickness, it turns out that space travel is an absolute nightmare on a delicate human meat suits.
Below are some of the worst parts of traveling through space — and that’s only what we know so far! Surely more terrible things await us in the vastness of space.
Space corpses are forever
![Space is littered I with corpses. S C'EASSA CIDATES TO 1:35 Too FIXT . D Space travel was first tested with dogs, chimpanzees, and other animals- many of whom died during their travels and whose bodies have never been recovered.

Your space DNA is different now
![Space will change your DNA. NASA NASA discovered this by comparing the DNA of astronaut Scott Kelly to that of his twin brother, Mark. After a year in space, Scott's genes had been altered by 7%- effectively making the twins non-identical. CRACKED.COM](https://s3.crackedcdn.com/phpimages/imageset/6/5/1/844651.jpg)

The Ice! It Burns!
![There is a planet where ice burns. The temperature on Gliese 436 b hovers around 800 degrees fahrenheit. However the ice doesn't melt because of the planet's gravitational pull- so instead it burns due to the extreme heat. CRACKED.COM](https://s3.crackedcdn.com/phpimages/imageset/6/5/0/844650.jpg)
You can't taste in space

THE WAY YOU HANDLE INSULIN GOES НА YWIRE. Even conventional diabetes treatments fall short. We do see some possible relief from a heart-friendly chemical called resveratrol, found in red wine.

Space tech is basically ancient
![THIS RUSSIAN SOYUZ IS HOW WE REACH THE ISS. СОЮЗ IT WAS DESIGNED IN 1962. Yeah, space tech can be ancient. The Soyuz remained unchanged for decades. Its computer went digital only in 2010, and it uses buttons an operator must push with a stick. NASA are only now switching to an alternative: the Crew Dragon, made by SpaceX.

Seriously, no babies!
![SHUTTLES OF COURSE ALLOW NO BABIES. BUT LONG-TERM, HOW WOULD BABIES WORK? If we plan to travel long-term and also continue as a species, babies will be kind of a necessity. You can't make babies exercise the way adults do. How space radiation and other fun elements of interplanetary travel will mess with them is anyone's guess.

So much for steering in space
![STEERING WHILE IN ORBIT IS CRAZY HARD. ACCELERATE? THAT RAISES YOUR ORBIT. To lower your orbit, you now need negative force from your rockets. But since you're getting closer to Earth, and gravity's growing, your kinetic energy actually increases, so you're likely to accelerate again. Confused? You should be.

Your poor spinal disks
![SPINAL DISKS CUSHION YOU AGAINST GRAVITY. IN SPACE, THESE BECOME USELESS. So your vertebrae drift and extend your spine. The good news: you get taller. The bad news: chronic back pain as a very nerve-dense part of your body suddenly stretches like an accordion. Oh, and the nerves themselves are also in danger of getting damaged.

Look at all this... nothing!
![IN MOVIES, SHIPS TOUR COLORFUL NEBULAE. BUT SPACE IS ALMOST ENTIREL Y EMPTY. You'll generally be looking out at nothing. Even if you stare right at one of the few sights, it'll never look like the cool colorful photos from the Hubble telescope.

In space... no one better smooch.
![ROMANCE IS FORBIDDEN AMONG ASTRONAUTS. NASA SAYS COUPLES CAN'T SHARE A SHIP. The one exception was when the couple married right before launch, and it was too late to change plans. NASA knows the true power of love is its ability to make even brilliant people turn crazy. That simply can't be allowed to happen on a starship.

Your bones and muscles give up
![BONES AND MUSCLES ATROPHY IN SPACE. РОСКОС RETURNING TO EARTH IS A HUGE ADJUSTMENT. You might be missing 8 percent of the bone across your hips, and that's even with all the exercise. You also have to readjust mentally. You'll try to float a pen or a water bottle over to someone and watch it clunk to the ground, because you've forgotten about gravity.

There's no stopping, pretty much
![ENGINE DIES ON EARTH? FRICTION STOPS YOU. IN SPACE? YOU KEEP MOVING, HELPLESS. Banking on a rescue? But any ship chasing you must first match your speed, and then go even faster to catch up. And don't count on sci-fi style escape pods. They'd have to be functioning space shuttles of their own and will probably never be practical to include.

We need extra pee tools
![MEN MUST PEE USING A FUNNEL. WOMEN MUST PEE USING A CUP. Pee's converted into drinking water, because up there, every drop of liquid counts. The real trick is knowing when you need to go.

There's not a lot of extra room
![EVERY SPARE INCH IS USED FOR STORAGE. FUEL, FOOD, PARTS, MED SUPPLIES... Those are the systems whose sharp corners you will continually be banging against every time you make a sudden movement. Designers can't throw in extra head room just to make you comfortable. Every extra bit of ship is going to cost somebody millions.

Neptune is hungry

Earth vs Space
![Space attacked Earth in 1859- and it might again. In 1859, the largest solar storm ever recorded hit earth causing light storms and failed telegraph communications. If the same storm were to occur again it would cause grid and WiFi failures to the tune of 2 trillion dollars. CRACKED.COM](https://s3.crackedcdn.com/phpimages/imageset/6/3/1/844631.jpg)

Sorry, no jetpacks
![SPACE JETPACKS DON'T EXIST. THE CLOSEST THING WAS SCRAPPED. The one in Gravity is based on the Manned Maneuvering Unit, which dates back to 1984. Its tiny compressed nitrogen thrusters couldn't move you at anything beyond a crawl. Besides, shuttles can just park next to you, so NASA dropped the MMU.

Space internet stinks
![SPACE DOES HAVE THE INTERNET. BUT IT'S SUPER SLOW. The issue is distance.

Radiation and your retinas
![RADIATION HITS YOUR RETINAS IN SPACE. THAT'S EVEN WHEN YOU CLOSE YOUR EYES. This tricks your brain into thinking you're seeing lights, which goes from inconvenient to inescapable. The constant radiation penetration also structurally damages the delicate tissues in your eyes, which may well lead to permanently messed-up sight.

Space weakens your heart
