Five satellites are now leaving the solar system escape trajectories. Further from the Sun is Voyager 1, which is more than 100 AU away and moves to 3.6 years by the African Union. [4] Compared Proxima Centauri, the nearest star is the Sun, is 267 000 AU distant. Voyager 1 will require more than 74,000 years to reach that distance. Vehicles designed using other techniques such as nuclear power pulses is likely to be able to reach the nearest star much faster.
Another possibility, which could allow human spaceflight and interstellar space is to use the time dilation, as this will allow passengers with a quick movement of the vehicle to travel farther into the future of aging very little, because of their high-speed, slow wear accounted for the train in time. However, to achieve such high speeds still need a new, advanced propulsion.

A manned or unmanned space travel between stars is interstellar space travel. There are lots of difficulties in interstellar travel. There are lots of difficulties that needs to overcome in interstellar travel. The long travel times make it difficult to design manned missions. The interstellar mission cannot be completed within 50 years. The prime targets for inter stellar travel are Alpha Centuari, Barnard’s Star, Sirius, Epilson Eridani, Tau Ceti and Gliese 581.
The nuclear rocket concepts include Fission Powered Rockets, Fusion Rockets, Nuclear Pulse Propulsion and Anti matter rockets. The non rocket concepts include Inter Stellar ramjets, charged blackhole jumping and beamed propulsion
