Dr. Marin and Dr. Beluffi begin their latest study by considering the various concepts that have been proposed for making an interstellar journey...also took into account missions that will be launching in the coming years like NASAs Parker Solar Probe. This probe will reach record-breaking orbital velocities of up to 724,205 km/h, which works out to about 200 km/s (or 0.067% the speed of light).
With their baseline for speed and travel time established 200 km/s and 6300 years Dr. Marin and Dr. Beluffi then set out to determine the minimum number of people needed to ensure that a healthy crew arrived at Proxima b.
We are using a ...stochastic Monte Carlo code that accounts for all possible outcomes of space simulations by testing every randomized scenario for procreation, life and death. By looping the simulation thousands of times, we get statistical values that are representative of a real space travel for a multi-generational crew. The code accounts for as many biological factors as possible and is currently being developed to include more and more physics.
These biological factors include things like the number of women vs. men, their respective ages, life expectancy, fertility rates, birth rates, and how long the crew would have to reproduce. It also took into account...accidents, disasters, catastrophic events, and the number of crew members likely to be effected by them.
They then averaged the results of these simulations over 100 interstellar journeys based on these various factors and different values to determine the size of the minimum crew... of 98 crew members would be needed to sustain a multi-generational voyage to the nearest star system with a potentially-habitable exoplanet.

And Muslims. The Sun is closer.
At least enough to operate the Warp Drive.
It’s all silly: if you build a ship that works... you have a world in itself. It doesn’t need to go anywhere.
You would want to send Zero people there.
Proxima Centaurs is a flare star. It frequently erupts with massive amounts of radiation, so, it would NOT be a good place for humans at all.
Tau Ceti or 61 Cygni might be better.
Optimum would be to take a metallic asteroid, or other mass, and manipulate it- like a glassblower- into a cylinder.
Boy I pity the first engineers in charge of that project!
Will they have a smoking section?
535
I think the answer is 42.
Bump! Had the same thought :)
What's a 'there Momentum Limited spacecraft?'
1) I believe 600 human beings, based on families of less than 5, is the genetic diversity to prevent inbreeding. 2) ALL THE MUSLIMS. We take them in aboard dropships that explode one hour after landing. This allows them to completely abandon tech, which they clearly hate, and if we come back in 100 years, everybody will be dead...because they will slaughter each other over vital arguments such as what Mohammed ate for breakfast.
Heinlein and others have shown that the poor bastards in a colony ship will arrive to find the planet already inhabited and thriving from the generations of colonists who hopped the FTL ship that left earth after the tech was invented a century later.
Read Larry Niven’s Known Space collection of books. The probes sent from Earth were badly programmed...and yes, the generation ships had it rough when they got there.
Those were good books; though Ringworld was the better out of that series of four.
Don’t really need FTL. Build a ship that travels .5 SoL and they wouls reach Proxima in 8 or nine years . What gappens after tgat depends on what they find. If they find no hospitable planets maybe on their return they search out for the first ship and lead them home. Turtledove created a similar scenario in tge last book of the Worl War Series.
I suspect the genetic inbreeding he worried about with a crew of 32 would also affect a crew of 98 over that long a trip. Whoever got off the ship at the end of the journey would probably be a liberal.
A typo. There should have been their.
