New Project Plans To Send A Spacecraft To Alpha Centauri In 20 Years

A new project has been announced that will attempt to launch a small spacecraft to our nearest stellar neighbor, Alpha Centauri, and return images and data to Earth within a generation
This is what we need, some pioneers that takes the first step to show other that it is or can be possible

This wont effect me in any way!:yep:

I've been playing too much Elite: Dangerous - my first thought was 'Alpha Centauri? That won't take long...' :o

Probably won't affect me either, but if I am around when they launch it I'll spend ever single one of my remaining days asking "Are we there yet?"

When (ha) we finally move, and I find out which box I put my copy in, I'll try and let you know. :03::yep:

You can buy it for $5,99 from GoG.com, their version should work fine on newer systems.

They said it'll only be a very small spaceship, so who's going to steer it?

The Robinson family or robot on the new, Jupiter 2. :yep:

To infinity and beyond.

I think a simple calculation will show that if you could get the craft to Alpha Centauri you would never be able to learn that it arrived. You'll never generate the power for a receivable signal from a small circuit board. If you could generate 1 watt that would be amazing. However our most dense storage devices, Lithium based batteries are good for 3 years before they quickly degrade to uselessness. If you build a craft so small you would only have enough space for about a 300mAh battery. At a 10C discharge, that's 3 amps for 6 minutes then kaput. And that's if it would retain 100% of its capacity, which it wouldn't.

I may be optimistic. The camera might take up the space that I figured for the battery. I bet this thing would have a 30% chance of detection from the moon.

You still in your old house?

That's about the only good thing about moving, you find a lot of stuff you forgot you ever had...

For the moment, latest ETD is sometime at the end of this month/beginning of next month. :yep:

I guess most of you know the story behind the struggle NASA had to send the first man to the Moon and the bonus they got from the development.

I could very well see some new "bonus" in future space travel and in our daily life-such as new kind of battery, cameras a.s.o

David Brin's 2012 book Existance uses these laser propelled solar sails in an interesting slant. Not only do they get a big push from the laser on the way out, but they use the sail as a brake when approaching a star system.

The power available to transmit images could be supplied by the sail if it also worked as a collector and twenty years in electronics development will bring some amazing changes.

I'm OK with it and I'm happy they're choosing a spacecraft. Watercraft just don't cut it. :88)
