2016/10/10 On this day in 1519, the Magellan expedition had been at sea for a week since leaving the Canary Islands.
According to Reference #1 (Page lx) the expedition next reached land on the 29th of November.
The scribe Antonio Pigafetta reported that the expedition left Seville with 237 people.
According to Note 8 (Page 131), more personnel were added in the Canary Islands, so that the total count of personnel was between 260 and 280.
Because this thread is intended to study alternate futures for human migration away from Earth in coming centuries, current publications which relate to this theme will be included.http://arstechnica.com/science/2016/10/ ... forgotten/
This article by Annalee Newitz - 10/5/2016, is focused on Martian settlements, but it covers the entire range of future settlement options.
Because this is the "Knowledge Forum" created by Dr. Dartnell, it is also appropriate to note that Ms. Newitz is an author of a similar (sounding) book.
Annalee Newitz is the Tech Culture Editor at Ars Technica. She is also the author of Scatter, Adapt, and Remember: How Humans Will Survive a Mass Extinction, and her first novel will be published in 2017.

Drs. Finney and Jones open their Chapter “The Exploring Animal” with the line:
We Home sapiens are by nature wanderers, ...
While I like this bold opening line, I note that the race has a wide range of proclivities, of which an impulse toward exploration is just one, and (in my opinion) that proclivity is not distributed equally.
By my observation, for much of human history, and even in much of the world today, there is a strong tendency to stay close to home. It seems likely (to me at least) that the oft noted tendency of people to not stray more than 25 miles from home is less likely to prevail in the industrial age.
However, from the point of view of one contemplating slow propagation of human civilization out away from Earth for thousands of years, it seems to be that the ability to find satisfying lives within 25 miles or so of one's birth place is vitally important, and FAR more important than the impulse to explore.
On 2016/10/13, I'd like to add a thought to this thread, that I have not seen anywhere before.
I'm introducing the thought that a community of humans away from Earth might establish a policy that any technology that is in use must be supported by a person who understands it.
In multiple science fiction stories I've read over the years, the authors have described cultures which are using technology that came to them from an advanced civilization, and which they do not understand.
That situation describes the human race for most of its history, if agriculture, animal husbandry, and human life itself are considered technologies.
My computer workstations are running a combination of Linux and Windows operating systems, and other devices have a variety of Android operating systems. The Linux and Windows systems just asked for permission to install updates, and I granted approval.
In granting approval, I reflected that I have no idea what the folks behind the updates are doing. I trust them to be doing things on my behalf, or at least things that will not be injurious.
Still, I DO have the impression that there are groups of people who are able to understand the operating systems they are supporting, and that for each update, at least ONE person understands what is to be done, and what problem it is intended to address.
The Amish are famous for trying to maintain their "civilization" at an 18th Century level, but at the same time, younger members of this group are (apparently) willing to use wireless telephone/computers.
I would guess that it might be possible that no ONE person on Earth understands an object such as a modern iPhone or the competitive equivalent.
May every member of The Knowledge forum grow financially, intellectually, socially and beyond.
