Future Space Travel

Futuristic Models:

• The General Theory of Relativity suggests dimensions beyond time and 3 dimensional space

• SOME FUTURE MODELS :1. Warp Drive.2. Nuclear pulse propulsion.3. Solar sail.

Solar Sails

• Also called as “light sails” & “photon sails”.

• Uses the radiation pressure or the solar pressure from stars to push large ultra thin mirrors to high speed.

• Every second solar winds are emerging from the stars(sun).

• It offers the possibility of low cost operations.

• Solar pressure affects almost every objects in the universe.

• A typical spacecraft going to Mars, for example, will be displaced by thousands of kilometers by solar pressure.

• For using this energy effectively “solar sails” theory is formed.

NUCLEAR PULSE PROPULSION

• Driven by series of nuclear explosions.

• Increases speed by stage by stage..• Atlast it acquires the “Speed of light”..• CURRENT PROJECTS :• Project Orion :

-would use nuclear bombs as propellant, possible with existing technology.• Project Medusa :

-uses large sail to maximize energy deposited by nuclear blast.

• Antimatter Catalyzed NPP :-antimatter reduces the amount of

material needed for fission reaction.

Warp drive

• Uses gravitational effect to compress the space-time in front of spacecraft then expand the space-time behind it.

• Relativity suggest it might be possible..

• Outside observers would see the spacecraft move “faster than light”.

• Inside observers would not feel any acceleration

• The net effect is rather like surfing where you are nearly stationary with respect to the wave, but are traveling with the speed of the wave.

• Nasa currently working on such a theory called “SPEEDS”.

• It could take a spacecraft to Alpha Centauri in a mere two weeks eventhough the system is 4.3 light-years away..

In the next 50 years, science fiction will have become science fact.

Space-Opens endless number of channels for engineers.

The final adventure for those seeking the unknown.

Perhaps you will be the one to discover this type of technology..
