Space exploration is the on going discovery and exploration of celestial structures in outer space technology. While the study of space is carried out mainly by astronomores with telescopes. The physical exploration of space is conducted both by unmanned robotic probes and human spaceflight.
Space travel how it works
Like jet airplanes,space shuttles have a thing called action and reaction.That is a massive force generated by hot gases firing backward from a rockets engines produces an equal force that pushes the rocket forward through space.
Even the fastest humans and spacecraft launched thus far would take many thousands of years to reach the closest stars. Space shuttle can travel ip tp 17 times the speed of light that is way faster than any on can imagine. Speeds about 75 times faster than this would be required if we hope to make an installer trip in less than a hundred years.
