No, there have been quite a few failures, two space shuttles having failed, plus Opollo 13 come immediately to mind.
The Sputnik 1 was successful, but there'd been several failed attempts before that one.
getting training always...(been trained always) :)
I think it was the Apollo 1 because there have been more than 1 Apollo there have been about 17 Apollo's and Apollo 13 was called the successful failure
The US officially won the space race in 1969 with the successful moon landing; since it is 2013 as I type, it has been 44 years since 1969.
It has always been in mankind's nature to explore beyond the world around him.
4d as in four dimensions have never actually been made. It is always present. Have always been present. Will always be present. Three dimensions we consider on a day to day basis is length, width and debth. Knowing these variables makes it possible to calculate positions in space. By adding a fourth dimension (time) we can calculate motion in space. As motion has always been present and will always be present, we can not say that somebody has invented or made this.
Of course it has. In fact space has been around for as long as the universe has been in existence. Look at space as a body of water; it has length, width, and depth. Now put a trampoline over the surface. This is space-time. Everything in existence sits on this "trampoline" as matter with mass, pressing down no the surface. Now take out the space (water) and nothing is there to support time, the (trampoline). So without space we wouldn't have time, movement, or any matter or mass today. Nothing would exist. So yes, Earth has been in space indefinitely and always will be.
There are so many problems that are associated with space exploration. Some of the problems include the high costs, the risk level is also very high and there are chances of getting negative results.
There have not been any air samples taken from space because there is no air in space. Space is vast and there are always particles (usually hydrogen and helium) floating around. However, there is so few particles relative to the vastness of space, that taking samples of the "air" wouldn't accomplish much.
The concept of space stations dates back to the early 20th century, with the first successful space station being Salyut 1, launched by the Soviet Union in 1971. Since then, numerous space stations have been launched and continue to be utilized for scientific research and space exploration.

The Champ de Mars, where the tower stands, has always been an open space.
