Fun is very important. Without fun, nobody could enjoy themselves. In fact, that reminds me of a story…

I was about 7 at the time, going to swimming lessons every week. The problem was, I didn’t like them. I dreaded these classes, and my overall mood lowered, making me sad. Eventually, my parents noticed and took me out of the classes. Later, they booked a piano class, which was much more interesting and gave me something to do at home. My mood improved, and I had something to practice at home, too! Afterwards, I became very good at piano, practicing at a senior level.

It just goes to show that fun is very important.


Chances are, you’ve heard of the ISS (International Space Station). It’s one of the most famous spacecrafts in the world. But what exactly is it?

WHAT DOES IT DO?                                                                                                                                   The ISS is important because of two main reasons. (1) It allows humans to live in space and allow NASA scientists back on earth to be able to identify outer space’s effects on their bodies and (2) allow inhabitants of it to perform research that can’t be done in any location on earth. This produces products in everyday life, called ‘spinoffs’. The International Space Station is also one of NASA’s first steps towards the exploration of other planets.

The ISS is one of the most important manmade creations in the world, aiding scientific researchers in exploration and maybe even colonization of other worlds.

Effects of Microgravity on the Human Body

One of the most serious issues of astronauts is zero gravity. This affects their body as it is used to dealing with the gravitational pull of earth. For example, the loss of pressure on bones can destabilize them causing bone loss.

As the Scientific American expertly puts it, “In microgravity, bone loss occurs at a rate of 1 to 1.5 percent a month, leading to an acceleration of age-related changes similar to osteoporosis.Decreases in bone density and strength are more pronounced in some skeletal regions, such as the pelvis, although much of the loss is reversible upon return to Earth.” The effects of space also increases the risk of bone fractures and the body’s ability to heal them.

Muscle loss is another one of the key factors of microgravity. For reasons unknown, microgravity changes the physiology of the heart. When these astronauts return to Earth, some of them may experience an ‘impaired orthostatic response,’ which is when their blood pressure get very low by moving from a lying down position to a sitting position.

These are just two of the many impacts of microgravity. I hope you finished reading this article knowing something new.
