According to many resources it took Apollo missions three days to get to the moon but it obviously depends on the aircraft the space stations are using. Apollo 11 were travelling at around 11km per second at full speed. The distance from the earth to the moon is 384,400km. But the quickest trip to the moon was the New Horizons Probe which went at a rapid speed and got to the moon in just 8 hours and 35 minutes, however they were on their way to Pluto!

For example, freeze-drying was a technique that was developed. Food was cooked, quickly frozen, and then dehydrated in a special vacuum chamber. Freeze dried food didn't need to be refrigerated and would last a long time.

To make most freeze-dried foods, astronauts squeeze water into the food packages and then eat the food after it absorbs the water. Astronauts can use hot water to make hot meals that are tasty and nutritious.

Some freeze-dried foods, like fruit, can be eaten dry. In fact, you may eat astronaut food from time to time without realizing it. 

One of the most important reasons why astronauts wear white is so they don’t get hot so they have thick layers they are so thick that the suit weighs 49.895 kgs but they also don’t want to get cold so they have heaters in their gloves. They also wear white so other astronauts can see them in the dark surroundings and if you go flying off into space they can see you. Also they have other coloured stripes for when they go into space in pairs they have the same coloured or amount stripes. All three of my sources provided these reasons.

Did you know that if astronauts want to eat freeze-food they have to pour water into a container and wait for the water to absorb before they can eat it. Also, astronauts usually eat dried fruit and ice cream. If the astronauts want their food to be hot, then they pour hot water into the container. The meals in space are very similar to the meals we have here on earth, space foods are served in plastic containers. There are some foods that can just be eaten the way they are like fruit, bread, nuts etc.

It should not be expanding because it was big enough in 1972.

All of this information was from asa.

Well everyone thinks there is no gravity in space but there actually is.  Gravity is what keeps the moon in orbit with earth and where ever you go in space you will always be able to find a small amount of gravity because if there was no gravity in space, we would just float away from all the other planets like the sun and eventually all die.

Space has gravity but hardly any also known as micro gravity. Micro as very small and gravity as gravity. Because of micro gravity humans apear weightless but so does everything else so you can manage to lift hundreds of kg’s with the tip of your finger. Micro gravity can also be called zero gravity but usily you call it micro.

So, you can cry in space! That is really surprising, considering that space has no gravity or oxygen and is 3 degrees celcius. The tears that you make will immediately start to boil, then turn to gas. But it doesn’t end there! Once the water has boiled, you would now have some isolated water molecules in a gas state, but in a freezing environment. This causes the tiny water vapor droplets to freeze and become snowflakes. That means, (stay with me this is it...) YOU ARE AN UNLIMITED SNOWFLAKE GENERATOR. That is, if you’re immortal and can survive for more than 7 seconds in an environment with no gravity or oxygen with freezing temperatures. 

When you cry in zero gravity however, it’s much more boring. The tears form a sphere shape under your eyes and get bigger and bigger until they are too big to stay on your face, and they float off into the air. If you were in a helmet, it's possible to drown in your measly little tears. 

Then my curiosity got the better of my lazy self and I wanted to know why it forms a sphere, (and I wanted to make this paragraph longer). When in space, with the absence of gravity, whatever cohesive force, water actually comes into play. So – to begin with, water forms a sphere. And the surface tension, which on earth is overcome by the force! Ahem...of gravity, is enough to hold the water in the sphere in place.When you have such a sphere, any sudden reaction caused on the surface of this – from either small projectiles of air or water, actually form waves on the self contained water bubble. In space the surface tension is strong enough for the bubble to not fall apart. Yes, small amounts of water can get thrown off and detached, but they’d remain in the form of spheres of their own.

There are ovens in most space ships and in the space stations to heat foods. If they don't have ovens in their space ships they use hot water but there are no refrigerators in space so space food can't be cold. Every few months an automated spacecraft goes up to space to give the astronauts fresh fruits, veggies and packeted foods. You can get foods such as ketchup, mustard and mayonnaise but astronauts only get salt and pepper in liquid form because astronauts can’t sprinkle salt and pepper on their food or it might float away and clog something up. There are currently 150 different types of space food and 300 things on the menu at the international space station.

temperature, which results in the formation of gas bubbles. I have learned a lot from all the research that I did and I would not want to be in space without a spacesuit.

Most asteroids are leftover parts from the making of the solar system. There are different types of asteroids. Some are made clay, others made with metal like iron and nickel. The Birth of jupiter prevented objects like dwarf planets and large moons from forming in the gap between Jupiter and Mars. Causing the moons and dwarf planets to collide with each other, making some of the asteroids we see today. Asteroids can fall down to earth if they come into the earth orbit. The asteroid vaporizes and hurtles down or past earth. Collisions in an asteroid belt can cause them to tumble down to earth as well. Let's hope that doesn’t happen!

According to the Youtube channel; Thoughty2 we should go to the Moon first because it has a lot less gravity .So it might be easier to build on it .Some temporary sleep and eat shafts could be built for the workers preparing the builders which will also be the colonists for the mars colonization they will also build the well coined ‘space gun’. It would be huge and very dangerous so let's leave it to N.A.S.A because we don’t want it firing at earth. 

That was stage one now for stage two which will be a lot harder . If we load the ‘space gun’ with say an atomic bomb . That will hit the polar icecaps on mars which is made out of frozen carbon dioxide which upon impact would melt and evaporate making clouds in the sky as a way to trap sunlight and help keep the planet warm . Then we can use the space gun once more to fire supplies on mars . Normally the supplies would burn up on reentry but if we attach something like a parachute It could glide to Mars’s surface and mark the place were the colonists would land .

 Now stage three which I want to call ‘getting there ‘ .If N.A.S.A gets a new SLS (space launch system) for another Orion (which is the biggest space station in space ) would help them build them make a bigger rocket .Which is important because altogether they will be in space for thirty nine days (approximately) so the astronauts need space to move around ,plus a bigger space ship would mean more resources so the colonists so the colonists could take it down for parts  . So basically if N.A.S.A gets a new SLS then they could build another Orion which could house the new colonists when they land on mars  .But first they land on the moon , it would be the most people on the Moon since 1969 ( they moon landing if you didn’t know )to get extra food fuel and last checks of the systems and other things  .Then to the final destination mars . 

Now to stage four this is when It gets icky . So the colonists can live off the supplies that are already there for a while . But then when it runs out they will have to eat poop as well as use it as plant fertilizer because as well as food .In the supliles package there will also be seeds so the plants will help make oxygen and food ! 

Once basic oxygen fills the atmosphere that will be kept in by the clouds and heated by the trapped light on mars the frozen water in the dirt and rocks would melt making rivers,oceans,and lakes that would might hold tiny microbes that would be the first nonhuman life on mars. With a little help from humanity could bring more trees and plants to help the oxygen spread and then the final step or destination .Humans could walk on mars without helmets . and that’s how we’ll terraform mars .
