Helios 2, launched in 1976, is the fastest man made craft at approximately 153,800 miles per hour. It is currently in an elliptical orbit around our sun, but ceased functioning in 1985.
As for manned craft, orbital craft such as the Space Shuttle travel between 17,000 and 18,000 miles per hour.
You must remember though, our galaxy is also moving. Our sun makes one revolution through the Milky Way once every 225 million years at a speed of approximately 480,000 miles per hour.
Our galaxy is traveling through space at approximately 1.3 million miles per hour.

Depends on your speed. A light year is the distance light travels in a year. If you traveled slower it would take longer.Depends on the speed you are going.At the speed of light one year.See related question for details of a light yearJust like any other distance, it depends on the speed of travel.-- At the speed of light, radio, x-rays, etc., it takes 1 year.-- At 1 million miles per hour, it takes about 671 years.-- At 60 miles per hour, it takes about 11.2 million years.A light year is the distance that light will travel in one year in a vacuum. The speed of light is 186,000 miles per second. So, light will travel about 5.8 trillion miles in one year. Now, to answer the question. The answer depends on how fast you are traveling. If you were in a space ship travelling 99.9999% the speed of light, it would take you about a year to travel a light year. Now, there is currently no human-made space craft, that we know of, that can travel that fast. The space shuttle travels at about 17,500 miles per hour. In order for the space shuttle to travel one light year, it would take about 38,262 years.
There are countless man made satelites are currently in space. This is because during space flight many piece of 'space junk' were left behind. If you are counting actually working equipment there are a little over 2200 satelites in space.

The International Space Station is currently in its 19th long duration expedition. Each is about six months long.

Space was created during the Big Bang and is currently expanding. Scientist theorize that space itself is composed of energy so therefore most of the universe is in the form of energy and not the matter that makes up the rocks. Currently no science can concretely prove what space is and what caused the Big Bang.
To see if it was safe for a human to travel into safe. If the monkey made it, a human might survive space travel. If the ape died, then it was not safe for a human to go into space. The chimp lived, so human beings were sent into outer space.
