I got 80%.
I didn't know that we had seen microorganisms living in space for over 3 years.
And, I fully contend that we CAN make it to Alpha Centauri within a reasonable amount of time.
4.36 LY = 41276662732800 m, 4.36 LY = 41,276,662,732.8 km
41 Billion, 276 Million, 662 Thousand, 732.8 Kilometers.
Now, what is 'a reasonable time' ? Is it 1 year? 5 years? 10? 20?
Considering the figure they listed is 76,000 - We'll go with 100 years.
13,080m/s / 300,000m/s = 0.0436
4.36 % of the speed of light!
It would have been easier to find that directly from the 4.36LY and 100 year figures, but less convincing.
13,080 m/s .. that means that 26,160 m/s is a 50 year trip. 52,320 m/s is 25.
The space station orbits at about 7,000 ft/s (trying to find my reference, that number may be a bit off) - there's 3 ft in a meter, so that's
2-3,000 m/s - unpropelled. Since there's no friction, or VERY little, a slowly building (or, quickly building) thrust could likely get even a larger
craft up to that within 2-3 years of successive bursts of thrust.
Honestly, with enough cash behind this, it would be quite 'doable' to get a craft of the proper size for 2-3 humans all the way to Alpha Centauri.
Many of the smaller technologies, such as closed-ecosystems for food and oxygen, successful safe fuel containment, etc... Are within our grasp. They
are just not being funded highly enough. They are generally independantly funded projects run poorly by interested individuals or low-funding programs
not taken seriously in NASA.
Give NASA money, and about 20 years, we would have a human-carrying craft off the ground and on a 75/80 year trip to AC. We could have a 1/2 kg craft
on a 20 year journey in less than 10. I strongly contest that answer.
