On this day in 1520, the Magellan Expedition continued sailing South along the East Coast of Brazil, heading toward Puerto San Julian
Begin Quotation from Page lx:
31 March 1520: The fleet enters Puerto San Julian (in 49 degrees 30 minutes South)
End Quotation.
The next landfall is reported as 49 degrees 30 minutes South, on March 31st. Google Earth reports this location as Puerto San Julian at S49 degrees 18 minutes.
The Expedition record of 49 degrees 30 minutes south does not correspond to the GPS coordinates reported today. The difference may be accounted for by the limitations of the mechanical navigation instruments of the day.
According to records of the voyage, the state of mind of some members of the five ship's crews was unsettled during this period.

Since the purpose of this thread is to consider alternative futures for humans expanding away from Earth, and since the technology of atom assemblers has been introduced previously as a logical and attractive way for a community away from Earth to maintain a high technology while at the same time distributing the means of production equitably across the population, I would like to focus today on the topic of fabrication of iron and iron alloy tools.
While it seems possible that it will be possible to form strong chemical bonds during the atom assembly process, it may turn out to be more efficient to assemble the atoms for a structure, such as a knife blade or a hammer head, and then use traditional procedures of heating and cooling (and perhaps compression operations) to improve the strength of the structures. I would expect it would take a month to assemble either of these structures.
