I still like Robert Winglee's idea of using mini-magetic Plasma propulsion(M2P2)....

But it will be interesting to see how this one works out...

How fast will that thing go before it runs outta fuel?

the space sail-craft does not need fuel irc

should be close to what they think M2p2 would do .. .which is

180,000 miles per hour in three months....

I found it most interesting to see how they are going to launch it.

Well hopfully its not a sham for testing a new weapons system in order to avoid international criticism ..

The sun provides the fuel. They also mentioned lasers. I don't believe either would provide much power beyond our solar system which is why I was wondering how fast it could go before losing power.

Why in the world would something like this be launched from a submarine, particularly a submerged one?

well one it gets to the speed the want it souldnt slow down ..... being space and the vacuum it should keep going at what ever speed they think is fast enough! the thing about this test is its the "1st attemp at a controlled solar sail"

i'm amazed the russians still have subs that work.

Actually it will slow down, space dust, gravity and all. May be by an insignificantly small amount though. I was just wondering if this presented real potential for interstellar travel.

Because solar sails continue accelerating, they could reach distant targets in amazing times.

It's never going to go faster than the Speed of Light. If it could equal the SOL, it would reach our nearest star in 4.3 years. (And there's nothing there of interest) So I guess 'amazing' is in the eye of the beholder.

In any event, I wish them all the luck.

(The submarine launch is a little strange. Not sure I understand that....)

This solar kite will fail, on purpose. There is not one reason to fire an extra-orbital missile from an undersea platform. Just to say you can is not enough. Therefore, the real mission is to simulate launching a LEOsat at sea. They could just tell us that, really, it is OK.

What he said.
