SPACE EXPLORATION; IS THIS THE ANSWER TO A DYING PLANET? EXPLODING POPULATION The world's population has increased from around 250 million people 2000 years ago, when time was first recorded, to currently a whopping, 7.035 billion now. Every week, about a million and a half people are added to the earth. It took us 150,000 years to reach a global number of 3 billion people, but it took 39 years for us to double that number to a ludicrously high 6 billion people on earth. At 1900, we had 1.6 billion people on the Earth. By 1960, we reached 3 billion. It is estimated that we use up resources so fast that by the year 2050, we will have to colonise extra planets to live on in space. FINITE RESOURCES IMPORTANT EVENTS IN SPACE EXPLORATION - PAST AND PRESENT ENVIRONMENT CHANGE
Is this Our Future??? Neil Armstrong & Buzz Aldrin landing on the moon for the first time in history.
July 20, 1969 A Rhesus monkey that originally came from Asia named Albert II became the first monkey in space. This mission helped scientists study whether humans could live in space. He flew in a specially adapted American V2 Rocket. A Russian dog called Laika became the first animal to orbit the Earth. Laika's mission helped scientists understand whether people could live in space. She travelled in a space ship known a Sputnik 2. The Russian Cosmonaut Yuri Gagarin became the first man in space. His space ship, Vostok 1, completed one orbit of the Earth and then landed about two hours after launch. Gagarin had out bail out and land using his parachute because his space ship, the Vostok 1, was designed to crash land! In 1963, the Russian cosmonaut Valentiva Tereshkova became the first woman in space. A crater on the far side of the moon is named after her! Neil Armstrong became the first man ever in history to walk on the moon's surface. This event held the world gobsmacked. A very famous quote said by Neil Armstrong on the moon was "One small step for man, one giant leap for mankind." Their space ship Apollo 11 worked perfectly, sending them an amazing 250,000 miles to the moon and safely back home again. In 1973, a Russian space probe called Mars 2 explored mars. One part of the probe stayed in orbit for a year, sending back pictures of Mars to Earth, and the other was to land on Mars and explore its surface but was destroyed when its parachute failed to open. Up until the 12th of April 1981, space ships were designed to be used once. Then the space shuttle was designed, which could supposedly be used for up to 100 visits to space. With five very powerful rocket motors, it can fly at a whopping speed of 17,000 miles per hour! In the past, the government has
been the main invester for space exploration. Organisations like NASA are run by the government, and the government decides how much money is going to be put into specific programs. There hasn't been much input or say from private companies for what will happen for space travel in the past, but now, there is!
Some private companies, such as VirginGalactic, are offering bookings for flights into space now! As with time comes change in the world, and change for companies, so that now private companies can offer space travel without becoming an astronaut! virgingalactic.com NASA USED FOR
INFO GATHERING NASA was, and still is, primarily used for info gathering. PEOPLE IN OUTER SPACE Is the answer to put our extra people in outer space??
What happens when these planets that we inhabit get overpopulated??
Who would stay on Earth and who would go into outer space???? Over a third of the world has been destroyed by the human race over the past thirty years! Graph showing the
supplies of water in
the world http://www.fao.org/docrep/u8480e/U8480E0c.htm Just one-hundredth of one per cent of the world's water is available for human use.
this would be enough for all human's to live off, - if it were evenly distributed. But it's not. In Malaysia 100 people share each million cubic metres of water; in India, the figure is 350 and in Israel, 4 000. Since 1970, forests have been reduced by 12%. The Earth's forests are being cleared at a miraculously high rate of 375km every day!! 1.1 billion acres of the world's tropical forestland have been cleared in merely three decades, between 1960 & 1990!!! http://www.worldcentric.org/conscious-living/environmental-destruction Would it work? How long would it take to colonise extra planets to live on??
Are there already resources available on other planets??
If not we would have to take into consideration testing the air,, building housing and hospitals, educational facilities, food, water, and many, many others!!
Food, for example: can food be grown in alien environments??
If so, what foods??
Water. Is there water available for humans to use, i.e. fresh drinking water, and water for all the other things we need it for, - sewerage, irrigation, hygiene, washing machines, and others.
Could we teach on other planets??
Would technology, which we so vastly rely upon now, work in space?? Taking into consideration food, water educational facilities, technology capabilities, oxygen allowances, housing and hospitals and the effects that living for even small periods of time, let alone for permanent living, in space has on the human body, is it really possible to create a safe, sustainable, livable environment for permanent living on another planet, or in space stations in space??
Possibly! Although, it would take decades of research, experiments and building to create an environment livable on another planet that has previously never had to provide resources to support life. So, really, all we can say about living on other planets or in space stations in space in the future, which may well happen if we don't massively curve our behavior and influences on the environment so that Earth can remain in domain of its vital capabilities to have the capacity to support life is......................
SIGNIFICANT: Muscle Atrophy
deterioration of the skeleton
slowing of heart functions
balance disorders
weakening of the immune system
LESS SIGNIFICANT: sleeping trouble
excess flatulence
blocked nose
loss of body mass
Most of these effects begin to quickly stop once the astronaut is back on Earth. But if people were permanently living in space, this would require extensive medical research and space experiments, just adding to the list of preparation tasks that would need to be completed if we were to have any hope of living in outer space. In 2000, the first crew permanently moved into the International Space Station. In April 2001, American Dennis Tito became the first space tourist. A new Airline, Virgin Galactic, in 2004, set up to offer private tourist flights into space, using a new version of this space plane. Tickets are available for flights, starting around 2012. Deforestation in the Amazon In January 2004, George Bush, president of the USA, said that NASA would continue missions to the moon by the year 2020, and then they would start work on a permanent moon-base. After that would be a manned mission to Mars, which might last up to two years. 2 DEFORESTATION WATER http://www.climatechange.gov.au/what-you-need-to-know/renewable-energy.aspx Sources of energy that are renewable include:
wind, solar, biomass, geothermal and hydro, and all of these sources naturally occur on our planet. RENEWABLE ENERGY THE END OF RESOURCES? http://www.thenaturalhealthplace.com/Articles/Oxygen.html http://www.grida.no/graphicslib/detail/forest-damage-due-to-air-pollution_80fc 14th June, 1949 November 1957 12th April, 1961 1963 20th July, 1969 1973 12th April 1981 2000 April, 2001 2004 January 2004 Hey Presto!
If living on another planet doesn't appeal to you, then maybe you should CHANGE the way we are abusing our planet and uncontrollably using up its resources! For more amazing info on space history, click on:
http://www.nasa.gov/agency/crm/shuttle/timeline.html SPACE JUNK Space junk and floating debris causes a significant
threat to the crew aboard a space station, with all
types of space junk ranging from spent rocket stages
and dead satellites to explosion fragments, paint flakes
and slag from solid rocket motors to micrometeoroids.
If the ground crew notices space debris on an orbit path
towards the space station, they notify the crew and safety
procedures will be performed. But will space junk be a problem for future living in space?? Would we have to dispose of our junk straight into space and if so, would this pose a greater threat to our safety?? Is it possible to do landfill on other planets, or dispose of rubbish as we normally would on Earth?? America throws out enough aluminium every week to be able to re-construct an airfield! Imagine not just this, but also thousands of other tonnes of waste being produced on other space stations and on other planets, like we normally would on Earth! Where would all this go?? Would it stay in the atmosphere of the planets or just keep polluting space?? SPACE STATIONS In 2,000,
the first crew moved in
permanently to the International
Space Station. These spacecraft are designed to support life in space, and have lots of
appliances similar to Earth. Our energy use Despite 75% of the world's surface being covered in water, 97.5% of it is salt water. Out of the reamaining 2.5%, most is unavailable for humans to use as it is stored as groundwater or locked in glaciers. KEY:
White = no forestland.
Green = forests left.
Brown = forests that have been cut down. Would virgingalactic, already doing paying passenger spaceflights, be one of the companies to fly people into space to live on other planets?? http://renewenergy.wordpress.com/transition/energy-resources/non-renewable/ The end of non-renewable resources for humans to use may be as such:
Est. world run out date:
Oil - With no increase in production, the current reserves are estimated to run out within 41 years.
Coal - There is proven to be roughly 847 billion tonnes of coal on the planet, which might last us for around 118 years.
Timber - The world's timber supply is estimated to run out within just 33 years. http://www.worldcoal.org/coal/where-is-coal-found/ REFERENCES http://www.spacekids.co.uk/spacehistory/

from 1900 to 2050. Martin Jenkins, senior adviser for the World Conservation Monitoring Centre in Cambridge, which helped compile the report, said: 'It seems things are getting worse faster than possibly ever before. Never has one single species had such an overwhelming influence. We are entering uncharted territory.'

The fact is that we are killing and abusing our planet so fast and so much, that within perhaps fifty years, the human race will have to colonise outer space planets and leave behind the planet called Earth, of which we have stripped its capacity to support life.
