I heard about this the other day on the radio but they were shitting them selves becasue they thought it was a manned mission. Still this is going to be cool getting telemetry from that place even if it is going to take years to get there and years to send back.

I wish we could send millions of them out in every direction of close star systems.

Every few years we could explore a new star system, and maybe we could gravitationally sling shot around stars and send them off to other stars, in 100 years we could explore dozens, maybe even a 100 star systems.

There are over 40 stars and brown dwarfs within 15 light years of our planet

This could lead to a fast and easier way to transport things around our solar. Shit, we could be poking around Titan in five years.

That would require a huge amount of lasers pointed in every direction.

But for sure the future is laser port at every stop to send or stop rockets. It's like the clippers of the next generation but with a vacuum. Send a solar powered laser to mars and you greatly decrease the cost. But further from the sun equals less solar power.

What do you guys think? A Dyson sphere concentrating energy to propel clippers through space?

How do they stop?

You would only need one laser system in each hemisphere.
The craft are moving independently of the earth, you would just have to fire at certain times of the day, the whole sky rotates around you every single day.

Why would they need to? I think idea is more or less for a flyby.

But long term, this would be cheaper than combustion. This would also work for manned missions.

You'd have to start decelerating 50% of the way there, if they're doing both with lasers. But they'd probably just use combustion to decelerate, which would significantly reduce weight too. Since it's for stopping and not the initial thrust. So I think that might work.

I realize it works great if you're just sending things out, but why develop this huge and incredibly useful ability and just use it to send out a dozen more voyagers?
