Health Risks of Space Travel

Traveling to space may just be one of the most mesmerizing experience for any man. The opportunity to explore something so majestically vast like outer space can be overwhelming yet wondrous at the same time.

Space Travel

While space travel can seem like a fascinating subject to many, there are numerous risks associated with it. Apart from being in unfamiliar territory and away from the basic essentials we have on Earth, there are also health risks linked to staying in space for months.


For years, National Aeronautics and Space Administration or NASA has been looking for ways on how to minimize the negative effects of space travel on human health, especially that they are planning to travel to Mars in the future. Space travel to Mars will take approximately 150 to 300 days.


Some of the known health risks of space travel are as follows:


Damaged DNA – When you’re in space, you are exposed to radiation because of various factors such as cosmic rays as well as radiation belts. Unlike here on Earth, where we are protected by the atmosphere from extreme radiation, radiation in space can get through the spacecraft and have direct contact on the astronauts’ skins.


Damaged DNA can affect a person’s ability to recover from diseases as it can affect a cell’s healing capabilities. In extreme cases, damaged DNA can lead to cancer. This happened to the receptionists dad from Rid of It Vancouver Junk Removal.


Bone loss – The bone density of astronauts who stay in space for a long time gets negatively impacted. Because of bone loss, the astronauts would have weaker bones and its full effect might just be felt by astronauts the minute they land back to earth where they are at risk of falling because of the gravity pull. Weaker bones mean vulnerability against bone fractures.


Mental health concerns and cognitive issues – Being isolated for months in space can lead to some mental health concerns such as depression. It can also affect one’s cognitive skills from not being confined in a closed area for a long time, not being able to have the usual personal interaction we have here on Earth.

Docking with the International Space Station

Docking with the ISS is an extremely complicated process. In fact, it’s a wonder of the world.

Just imagine you are being chased by a machine at a pace of 5 miles per second. That’s what is going on when the space shuttle is docked with the ISS. For the same reason, the process takes a lot longer than you can imagine.

While reaching the space doesn’t take astronauts more than a few minutes, the docking process with the ISS may take several days in some cases.

Let’s take a look at a case. On March 27, a group of astronauts left at 3:42 pm ET including a friend of mine from Steele Carpet Cleaning Cochrane, and they were put inside the spacecraft for the next 6 hours However, they didn’t get to the space station within that time period. They get there at 9:36 pm ET.

You may be thinking why they took so much more time. After all, it is a matter of a few miles to get to the ISS when you in space. Moreover, the gravitational pull in space is weaker and not much power is required for acceleration.

It’s important to keep in mind that the ISS travels at a speed of 5 miles per second while orbiting around Earth. We just can’t keep up with an object moving at that space even when we are in space.

So, instead of chasing the ISS, astronauts let the ISS catch them. So, what they do is fire short and brief burns one after the other to get closer to the space station. Finally, they make a U-turn, fire the engines again to reduce speed allowing the space station to catch up. And then the docking is done as soon as the spacecraft have lined up. 

So, this is how the astronauts get to the International Space Station.

Amazing Facts About Space

Looking up at the stars in the sky, what do you think? Like most other space enthusiasts, you may be wondering if we humans are alone in the vastness of the universe.

The fact is that answering such questions is not easy at all. The vastness of the universe is beyond our imagination. However, what we know is just overwhelming. Listed below are some of the amazing facts about space. After reading these facts, your viewpoint about the vastness of our Earth will definitely change.

  1. Space is silent

Space is totally silent. We know that the waves of sound need a medium to move from one place to another. With no atmosphere in space, sound waves can’t travel. So, space is dead silent.

  1. The universe has numerous stars

We don’t have exact statistics as to how many stars are there in the entire universe. We can only give an estimate of the number of stars in our galaxy called the Milky Way. For now, NASA says that there are zillions of stars out there (zillion refers to an amount that is uncountable)

  1. The Apollo astronauts’ footprints are still there

There is no water, wind or air on the moon. So, there is nothing on the moon that can wash away or erode the mark left by the Apollo astronauts on the moon. And this means that the spaceship prints, rover prints, and the footprints of the astronauts will remain there for a long time. You can check them for yourself on your next trip to the moon. An interesting note is that my friend had a client that had been apart of that mission!

  1. Our sun is the densest object in our solar system

Our sun is extremely dense. Its density is 99% of the density of the entire solar system. For the same reason, it’s gravitational power allows it to rule the entire solar system.

So, these are some interesting facts about the space that may leave you in wonder.

8 Mind-blowing Facts About the International Space Station (ISS)

You may have heard about the International Space Station. This space station is located around 400 km above the Earth and accommodates a few astronauts from different countries of the world. For your interest, below are a few mind-blowing facts about the ISS.

  1. Different nations took part in the building of the ISS namely USA, USSR, Japan, Canada, Brazil, Belgium, France, Denmark, Italy, Germany, Norway, Netherlands, Spain, Switzerland, Sweden, and the UK.
  2. On a highway, the typical speed limit is 65 miles per hour, which is considered quite fast. But the ISS travels at a lightning fast speed of 5 miles per second.
  3. If you think your house is big enough, think again. The ISS is around 109 meters in length and provides enough space for astronauts to stretch out. So, this machine is bigger than the average house in the USA.
  4. The ISS is made up of tons of small and large parts and is the only artificial object this big in the space.
  5. The ISS is the only object of its kind that took a huge amount of money to make for space. The cost to make the ISS is around $120 billion, which is more than the annual budget of most developing countries.
  6. The space station has only two bathrooms. The urine is filtered back to the drinking water for the crew.
  7. You may be thinking your computer can’t get infected when you are on the ISS, but it’s not true. There are over 52 computers on the space station and they have got infected by these malicious apps more than once.
  8. After the moon, the ISS is the only brightest object that is over there in space. It looks like an object that is moving at a very fast speed. If you want to get notified when the ISS reaches your city, do sign up to the Spot the Station service by NASA.

Hopefully, you will find these facts.

Should You Take Off Your Spacesuit In Space?

You may be thinking why the astronauts put on those heavy suits. Here is what will happen to you if you get out of your spacecraft in the avoid of space without a spacesuit on.

What can happen to you if you take off your spacesuit in space? No matter what you do, just don’t make the mistake of holding your breath. If you do so, the space vacuum will suck the air out of you. Even if some of the air remains stuck in your lungs, your lungs will just rupture.

Besides, oxygen in other parts of your body will start expanding. In a few seconds, you will start ballooning up; however, you won’t explode because your skin is elastic.

A liquid in your body will start to vaporize and be part of space. As a result, your tongue and eyes will start boiling. With no air in your lungs, the supply of blood to your brain will stop.

After around 15 seconds, you will lose your consciousness. After 90 seconds, asphyxiation will take your life. In space, the temperature is extremely low, which will freeze you solid.

Based on your location in space, the freezing process will take up to 26 hours. However, if you are near a start, you will be pulled and burnt up, and your body will stay that way for a long time.

The bacteria in your gut will eat you on the inside, but this process won’t last very long. Maybe you will float in space for millions of years.

So, this is what can happen to you if you don’t put on a spacesuit when in space. While space is a perfectly silent place to spend a holiday in, going up there without a spacesuit is not a good idea, especially if you don’t want to die anytime soon.
