IN JUST A FEW MONTHS, THE PLANETARY SOCIETY WILL LAUNCH COSMOS 1 -

THE FIRST SOLAR SAIL SPACECRAFT!

 

A solar sail is a spacecraft without an engine - it is pushed along directly by light particles from the Sun, reflecting off giant mirror-like sails. Because it carries no fuel and keeps accelerating over almost unlimited distances, it is the only technology now in existence that can one day take us to the stars.

How will it....return?

 

according to the article if it not able to achieve a stable orbit it will return to earth like skylab or bounce off into the cosmos to sail firever like an unmanned ghost ship..

And with the possibility of reaching 3/4ths of the speed of light...could go far...

 

But I'm jut wondering - can solar sails get you closer to the center of the galaxy? Wouldn't the higher amount of light emanating push you outwards? Unless, of course, you can make a sail that only offers resistane to light from one side....anyone know about this??

I think that the sail would be useless for the return mision.It would have to have an engine that it pushes in the return direction(sailing against the wind is hard I think).

 

sail boats do it all you have to do is tack the sail......

just watched DS9 explorers, where sisco and jake build a light ship and travelto the cardassian system.

 

 

Yes they just missed out the fact that light ships are slow - eventually they get fast due to constant acceleration.

 

Mind you the Solar Sail was originally science fiction (Arthur C Clarke). I like it when SciFi becomes SciFact :D :D
