The expansion of man’s reach into space will not be possible without the discovery of rockets. They have taken us to the moon and back. We have sent numerous probes and captured close glimpses of most members of our planetary neighborhood. Rockets enabled us to construct space stations and artificial satellites. They are still the mainstay of space propulsion and will continue to do so until we discover something better.
The primary usefulness of rockets is their incredible power to overcome earth’s gravity (or gravity in general), without which none of the above could have been possible. The only disadvantage is the direct correlation of the payload mass and the rocket fuel. The more people and instruments we want to put in space, the more rocket fuel we will need. Add to that the mass of the rocket fuel itself and we will see the reason of man’s slow advance in this final frontier. Using rockets is costly, limited, and requires a lot of complex logistics and management.
