Space

The Conditions At space the most dangerous conditions is that there is no air, it's pitch black and there's pressure and the fact that it can turn hot or cold any minute.The others conditions are that theres no food,water or etc... The final thing is that it has no gravity so it would be difficult to move.

Outer Space

LocationThe place beyond the Earth's atomosphere is called space. In space there are more planets and more galaxies too. although you would need rocket ships and advanced technology to get there.

TechnologyFlight has helped us into space. The curve of the wing affects flight, creating lift. Air rushes over the top curve faster than the bottom, creating low pressure on over the wing and high pressure on the bottom. The high pressure under the wing forces the plane up. That is how lift is created.Rocketing technology has allowed us to explore space. Scientists sent probes, unpiloted spacecrafts, into space before they sent people. To explore space, you would need a vehical that can travel in a vacuum, carry its own fuel and oxegen, and travel fast enough to escape the gravity on Earth. Eventaully, scientists made reusable rockets, designed to go to space and back. Anything lauched into space launched into a payload. A rocket carries the payload into space. The rocket has an opening at one end, forcing the air to escape from the opening to everything move forward. The rocket has a engine that mixes fuel with oxegen to create exhaust gas. The quick release of these gases creates a upward force, or thrust, to the rocket.A satellite is an object in space orbiting Earth or other planets. There are different types of satellites. One type are communcation satellites. Communication satellites recieve and transmit signals worldwide. There are also navigation, weather,research and even spy satellites. Space stations are significant to space exploration. Scientists research the effects of space on space stations, such as the ISS. The ISS is the largest technological project in space. Space agencies from 16 countries are all contributing to a project. The ISS is a laboratory in space that studies the effect of microgravity on organisms. Microgravity makes everything feel weightless, the ISS is a microgravity environment. They're also studying Earth's climate,the solar system and even making new technology to explore space. Space suits are very to all astronauts in space. Space suits protect astronauts from the exposure to space. The tempuratues of space can go from -157 C in the darkness to 121 C in full sunlight, so space suits are a must for astronauts. Astronauts wear special pressurized space suits, Launch and Entry Space Suits, or LES. LES provides enough air pressure come back to Earth and while emergency landings, due to when the pressure decreases. In space, astronauts wear Extravehicular Mobility Unit, or EMU, to work in space. EMUs have multiple layers to protect astronauts from the vacuum, extreme temperatures and the Sun's harmful radiation. There's a visor to protect eyes from the shining sun. Oxegen tanks can provide astronauts with about eight to nine hours of oxegen. There are also gloves with heaters, to prevent hands from freezing during working. EMUs also has a thermostat that is adjustable. Tubes coil through special underwear, keeping astronauts at a comfortable tempurature. There is also the Manned Manuevered Unit. It is a nitrogen propelled backpack attachable to the EMU. Astronauts wearing the MMU can move forward, backward,turn and even do flips! Living on the ISS depends on having food, water and ways to dispose waste. Astronauts have the average three meals per day, consisting of lots of nutriens and easy to eat from the floating environment. Food may include, fruit, nuts, peanut butter, chicken, beef, sedafood, etc. Their drinks also have special clamps to stop the liqueds from coming out after sucking. Most foods are precooked so you can preheat the food. There is no refridgerator on the ISS.Our breathe contains water, so technology purifies the humidity in your breathe to make water. Bringing water into space is expensive. In the future, scientists will use every single drop of water to recycle on the ISS. Toilets on the ISS has straps so the astronauts don't float away. There is also a rubber ring to create a seal around the toilet as the waste is vacuumed into a waste receptacle. All liqueds, including urine, is processed to remove all pure water to drink.

Why Humans Explore SpaceThere are many reasons people explore space. As the population grows, people try to find more places to live. Scientists are even thinking of having a colony on the moon or even mars! We also explore space for resources. Did you know some asteroids contain useful metals and other materials? Also because we are curious and want to find out if there is life or water on different planets. We can also find out more about the history of earth to understand our world and expand our knowledge.

Vegetation and AnimalsThere are no organisms in space. This is due to the conditions of space. No air, water, nutrients,habitat and the temperarure are all what prevents organisms to live in space. The temperatures vary, closer to the sun is hotter and farther is colder.

Canandian Contributions The Canadarm is a robotic arm first launched in 1981.It is used to send satellites in the right orbit, fix broken sateillites and used to knock of ice off the air vents. The RADARSAT is a sateillite that provides images that monitor disasters like: oil spills, flood damages and conditions of crops and animals.

Benefits from space explorationSpinoffs are technology used for exploration but have gotten into our daily lives. Did you know that NASA developed bar codes to keep track of space junk? Those are the same barcodes used by grocery departments to keep track of products. Technology used for space exploration such as robotics have given people the idea of mining, building cars, and oil exploration. Also, space foods have given the idea of frozen dried foods and microelectronics have gotten calculators, computers, and digital watches. Spinoffs are all around you and are a huge benefit from space exploration.
