Travel In A Spaceship Essay

One day I was at my house thinking what i should do…But then it came to me…I want to go to space.So i ran inside to talk my dad in to letting me go to the moon.He said i guess so, sense we don’t have anything to do today.So we went and bought a space ship downtown.As soon as we got the space ship we were of to the moon…It took a really long time to get to the moon.Once we got there we just looked and tried to find our planet.Whenever i found it i took a picture of it with my phone.And i noticed that whenever i was looking at it, it wasn’t light on each side of the Earth.So i knew it wasn’t a full moon it was a 1st quarter moon.Once i was done looking at Earth i told my dad that i was really hungry!!He said OK and fixed me some food.But i noticed that it didn’t look like the regular food i usually eat.I asked him what kind of food it was and he said it was space food.Once he was done heating it up i tried it and it tasted like a dead bird.When i was done eating that horrible food i went straight to sleep.When i woke up my back was aching.I woke my dad up and told him ”lets go explore the moon and get to know more about it”So he got up and we both were walking around the moon to see some things that we could bring with us back to Earth.We were looking around for about an hour or so.When we turned a corner we saw something that almost looked like was an we ran as fast as we could back to the space ship.When we got to the space ship we went as fast as we could back to Earth.Once we got home i told my dad that was really fun and i wanna go back again one day…He said me too..                                                    THE END

Have you ever dreamed of traveling in space? If you're like most kids, gazing at the stars at one time or another has led to a daydream about what it would be like to be an astronaut. Not only would it be tons of fun to travel on a spaceship, just think about how awesome it would be to set foot on the moon or another planet!

Of course, becoming an astronaut isn't easy. There aren't many astronauts in the world, so you have to be very skilled in a number of different areas. Astronauts have special combinations of skills that make them suitable to be traveling scientists beyond Earth.

Although it sounds like it would be great fun to travel to outerspace, it would be a lot of work, too. Traveling to outerspace takes lots and lots of preparation. Everything has to be planned carefully in advance. Why? Because once you leave Earth's surface, you're on your own with what you have in your spaceship. There's no store to go to in space!

Once you are in space, nothing can come on board the ship and nothing can go out. You must take everything you need to survive into outerspace with you. Let's call these items “inputs." Inputs might include necessities such asfood, water and oxygen.

Now let's talk about “outputs." Every input creates an output. Let's say you open a box of Coco Comets cereal for breakfast. What will you do with the box when it is empty? You only have so much room to store outputs on your spaceship. Every piece of garbage you create while on tour will remain on the ship with you. Where will you store the garbage? Can you think of a way to reduce the amount of wasteoutput you create during your time in space?

In order to survive, you must eat and drink, but this means your body will also process those food and water inputs and output them in the form of solid and liquid waste. Since nothing can leave the spaceship, you will need to think of a way to handle these bodily wastes. On Earth, we simply flush a toilet, but what happens after our bodily output leaves our homes and enters the sewer systems? Where does it go? It might seem icky, but this is an important question.

Even breathing creates an output — carbon dioxide! Can you think of a way to filter the carbon dioxide from the interior of your spaceship? And how will you replace it with the oxygen your crew needs to breathe? Hint: Plants love carbon dioxide and depend on it in the same way humans depend on oxygen to breathe.

Conveniently, plants outputoxygen! However, plants also have other input needs, such as water and fertilizer. If you bring a banana tree on board, your ship you will need to bring enough water to sustain it for a year. You must also consider another type of output the bananas will leave behind after you have snacked on the fruit — the peel! The banana peel will become another output to add to your garbage output pile. Can you think of other varieties of plants or trees that may provide a tasty treat without leaving a rind or peel behind for your garbage output pile?

See how carefully you have to plan for a trip to outerspace? Not only do you have to think about all the things you'll need, you have to consider the consequences of those things in terms of the wastes they create.

Packing for a trip to outerspace isn't as simple as packing your bag for a week at camp. Considering the impact of all your actions takes time and energy. And you can start right now! All of your actions here on Earth have impacts just like they would in space. How can you plan your actions on Earth to have the least impact on the environment and your future?
