about future space technologies and theories..

1. Future Space Travel

2. 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.

3. 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.

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

6. • 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.

7. NUCLEAR PULSE PROPULSION
• Driven by series of nuclear explosions.

8. • 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.

9. 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..

10. • 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.

12. • 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..

13.  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..
