This is an interesting paper estimating the minimum number of people required for a self-sufficient colony on Mars. Using a mathematical model to estimate work time requirements vs. work time capacity, the researchers come up with a surprisingly low number: 110.
In the forthcoming second book of the Generation Mars series, I peg the colony population at around 5000, so I think I’m good there.
I’ve been a little concerned that the actions and responsibilities taken on by Cas and Ori in my next Generation Mars book (still a WIP) are beyond what is possible for a six and eight year old. Turns out: nope.
Dr. Phil Metzger posted an epic 48 tweet thread on Twitter explaining why megaconstellations (e.g. SpaceX’s Starlink) are inevitable, as is their eventual demise as better tech comes online.
Looking at the evolution of life, from single celled organisms to bipedal apes rapidly outgrowing the planet, as the exponential growth of information is a novel (to me at least) approach and provides an interesting perspective.
“I would bet that if we find alien civilizations somewhere else in the galaxy, or in a galaxy far, far away, we will discover that they ALL developed megaconstellations right before they got industry off their planets & divorced their information systems from their biosphere.”
“This perfect society we’re striving towards should always be a spot on the horizon, something we’re still moving towards even if it seems like we’ve fixed everything. Utopia is a journey: not the happy ending, but the continued improvement of ourselves.”
This is a near perfect summation of my thoughts regarding Dawn Colony in Generation Mars.
