Space Travel

Space Exploration

Space exploration is the ongoing discovery and exploration of celestial structures in outer space technology. While the study of space is carried out mainly by astronomers with telescopes.,the physical exploration of space is conducted both by unmanned robotic probes and human spaceflight.

Space Travel

Even the fastest humans and spacecraft launched thus far would take many thousands of years to reach the closest stars.Speeds about 75 times faster than this would be required if we hope to make an installer trip in less than a hundred place.

How Space Travel Works

Like jet airplanes,space rockets work on a principle called action and reaction.The massive force generated by hot gases firing backward from a rockets engines produces an equal force that pushes the rocket forward through space. Most of the fuel on board a rocket is used in the first few minutes of the mission to achieve an escape velocity of at least 25,000 mph.
