Space Search – Man’s Fascination With Outer Space!
Never ending questions are the result of man’s fascination with what’s more to find in the outer space. The possibilities of the existence of another life form out there is something that has always inspired our scientist to look further out in the space. As new discoveries are made, new questions spawn from these findings as well.
The idea of Space Search is vitally important, for space search has fascinated humans for as long as there has been understanding about outer space.
For many years humans believed the earth was flat and if they went too far to the edge they would fall off. But even with this dangerous idea, a space search was never far from the minds of those more adventurous types.
Grecian and Aztec explorers used to describe the earth as a flat surface and it was Eratosthenes, a Greek mathematician who calculated the Earth’s diameter by a simple technique of using the shadows cast by the sun. But people were intrigued as to what lay beyond the earth and desperately wanted to find ways to go into space, search for other planets, and possibly even other forms of life.
For thousands of years the questions of space search continued to dominate all who were fascinated by what else was contained in the universe. Astrologers and astronomers tried to answer questions, but, for the most part, space search remained a big, black hole until the 20th century. It was in the 20th century that astronomers and scientists begin to look scientifically at what was out there, for more details visit to www.profit-pulling-niches.com and at the possibility of a space search expedition. And, in April 1961, Yuri Gagarin did what so many others had wanted to do before him, and became the first man into space.
Gagarin’s triumph was the culmination of a battle between the USA and Russia – each country wanted to be the first to put a man into space and thus begin an age of space search. The Americans had Alan Shepherd waiting in the wings to blast off into outer space and had little or for more details visit to www.auto-cons.com no idea that the Russians were ready with Gagarin.
Shepherd became the second man into space and to start a space search just a few weeks later, when he was shot up for about 15 minutes.
Since then space search has been a constant battle between the two countries with the astronauts of the USA and cosmonauts of Russia striving to explore more, to find more and to know more about space.
Space searches have hot some major setbacks in recent years, most notably with the Challenger in 1986, which was destroyed just a couple of minutes into its flight, and, more recently, with the Columbia in 2003 which broke up on re-entry to the earth’s atmosphere, killing all on board. Space flights did not resume until 2005, with careful attention being paid to them around the world.
The International Space Station remains in use, with a skeleton staff on board.
Until man has conquered every corner of the known universe, which would appear to be an unlikely feat, it seems humans will always be obsessed with space search. It is the fear of the unknown as well as the possibility of discovering other life which draws us ever closer. Right now, Richard Branson is preparing to take the first space tourism flights into the atmosphere, and it is unclear where the fascination will stop.

As long as space travel can permit humans to seek for what more is out there, so is the fascination of man with outer space. With the help of modern technologies, these queries will soon find its answers. We may never know how far the space can go, but only us can limit where we want to explore.
You’re ever exposed to conditions in outer-space!
To be able to travel space, you must have the mental and physical capabilities of an astronaut. You will also need a special kind of clothing that can withstand the hostile environment out there. These space suits are designed, equipped, and tested for that purpose.
For most of us, getting dressed for work is not something that we would consider a chore. We open the cupboard, pick a shirt and try to make sure that the rest isn’t too badly mismatched before stepping out to greet the day. Astronauts, however, do not have it quite as easy as we do. They may not have to make decisions on style, cut and colour, but they have to consider things like air pressure and possible bombardment by micrometeoroids. Getting it wrong could result in body fluids boiling and then freezing, as well as a severe case of the bends.
Space was not designed with tourists in mind. It’s a hostile environment with temperatures that fluctuate between 120 and -100 degrees Celsius and extreme radiation. There is no oxygen and no air pressure. Luckily, if you’re ever exposed to conditions in outer-space, you’ll only be conscious for about 15 seconds before all the oxygen is sucked from your body. That way perhaps you won’t notice being pelted by friendly fire from casually discarded space junk, nor will you be aware of your vital organs expanding and bursting in the vacuum created by zero air pressure.
All those travelling to space are therefore very grateful for the invention of spacesuits. Spacesuits perform a variety of functions all designed to keep those in them alive. They provide pure oxygen, remove carbon dioxide, regulate the temperature, protect against radiation and the dreaded micrometeoroids, all within a pressurised atmosphere. In addition to taking care of these vital physical needs, they also allow for (relatively) easy mobility and enable communication between astronauts in the suits and those within the (again, relative) safety of the space craft.
After much trial, error and refinement, the spacesuits worn for all of the Apollo missions consisted of a water-cooled nylon undergarment, multi-layers of nylon to maintain pressure, five layers of aluminised Mylar and four layers of Dacron to regulate temperature. They included additional heat protection in the form of two layers of Kapton, a layer of Teflon-coated cloth and a layer of Teflon cloth to protect against projectiles, as well as boots, gloves, for more details visit to www.arts-crafts-for-all.com and a helmet. Not to mention the extra pairs of over-boots and gloves that were needed to walk in space.
The modern spacesuit, known as an Extravehicular Mobility Unit (EMU), is designed to be more flexible, comfortable and to provide greater ease of movement. The EMU consists of 13 layers of material. Materials used include Kevlar (of bullet-proof vests fame), neoprene and urethane-coated nylon, and spandex.
EMUs are of the one size fits all variety, as opposed to earlier models, which were specially tailored to fit the astronauts. They weigh 127 kg (twice as much as the Apollo suits), require a 25-step process to put on and take off, for more details visit to www.profit-pulling-niches.com and cost $12 million each. Should astronauts find that they don’t offer the protection guaranteed, their next of kin can take the matter up with contractors Hamilton Sundstrand and ILC Dover.
Included in an EMU is a Maximum Absorption Garment (MAG) which collects urine and an In-Suit Drink Bag (IDB), so that the MAG has something to collect. These are actually two of the most important features of the EMU because astronauts can be stuck in their suits for up to seven hours, which is plenty of time for dehydration to set in. Working in space is challenging enough without astronauts having to worry about hydration levels and the next pee-break.

With the advancement of our technologies now, new designs of space suits are being developed. These suits will help our astronauts to do all their research out there in a more safe and comfortable way. Coming up with a space suits like these is also as challenging as being an astronauts themselves.
