** Map shows Mars settlers where to find water: NASA’s Treasure Map for Water Ice on Mars | NASA

“This rainbow-colored map shows underground water ice on Mars. Cool colors are closer to the surface than warm colors; black zones indicate areas where a spacecraft would sink into fine dust; the outlined box represents the ideal region to send astronauts for them to dig up water ice.

A new paper published in Geophysical Research Letters will help [select landing spots on Mars] by providing a map of water ice believed to be as little as an inch (2.5 centimeters) below the surface.

Water ice will be a key consideration for any potential landing site. With little room to spare aboard a spacecraft, any human missions to Mars will have to harvest what’s already available for drinking water and making rocket fuel.

NASA calls this concept “in situ resource utilization,” and it’s an important factor in selecting human landing sites on Mars. Satellites orbiting Mars are essential in helping scientists determine the best places for building the first Martian research station. The authors of the new paper make use of data from two of those spacecraft, NASA’s Mars Reconnaissance Orbiter (MRO) and Mars Odyssey orbiter, to locate water ice that could potentially be within reach of astronauts on the Red Planet.

“You wouldn’t need a backhoe to dig up this ice. You could use a shovel,” said the paper’s lead author, Sylvain Piqueux of NASA’s Jet Propulsion Laboratory in Pasadena, California. “We’re continuing to collect data on buried ice on Mars, zeroing in on the best places for astronauts to land.”

** A discussion of the definition of space settlement by Dale A. Skran: SPACE BASICS: What is Space Settlement? – National Space Society

Before we get too far into this, it is important to clearly differentiate between “space settlement” and “a space settlement.” Space settlement is the general process of developing and settling space. A space settlement is a specific place in space where people live, work, and raise families.

Let’s start with a relevant dictionary definition of settlement—“the settling of persons in a new place.” This definition is almost immediately self-referential, as it refers to “settling of persons.” When we look at “settle” the verb, we see definitions that include “to migrate to and organize (an area, territory, etc); colonize,” “to cause to take up residence,” and “to furnish (a place) with inhabitants or settlers.”

All these definitions revolve around people living in a new place—“colonizing,” “taking up residence,” etc. This is very important—“taking up residence” implies permanence, family life, a job, and so on. A soldier being assigned to a base for a year is not “colonizing” or “taking up residence”—instead they are “being deployed.” A scientist might be “assigned” to work at a base in Antarctica for a period of time, but they are not “colonizing” Antarctica.

Thus, I propose that a “space settlement” is a group of people (men, women, children) who move to some specific location in space (Moon, Mars, an asteroid, orbital free space, etc.) to take up permanent residence there. This implies that they will raise their children in this “space settlement,” work in or near the “space settlement,” and in all probability die and have their remains disposed of there as well.

Skan concludes with

To summarize, the space settlements we are working to establish have the following characteristics:

- Families live in them on a permanent basis
- The settlements engage in commercial activity that generates the wealth needed to sustain them, and are not dependant on infusions of government funds.
- They are large enough and diverse enough to be, at least potentially, both economically and biologically self-sustaining.
- They may have a variety of organizational forms, including kibbutz style common ownership of the settlement, systems based on private property, company towns, or religious communities.

** OffWorld is developing universal industrial robots for “heavy lifting” on Earth, Moon, asteroids and Mars: Meet OffWorld, the startup that wants to mine the moon with a swarm of robots | Digital Trends

To say that OffWorld’s dream is an ambitious one is to put it mildly. The company envisions a future in which millions of smart robots work together using swarm intelligence “on and offworld” to build the infrastructure of tomorrow. Long term, they even imagine the possibility of using the robots to mine for materials which could be used to build new chips “with zero reliance on terrestrial supply.”

** Space based solar power has been failed to reach orbit despite decades of proposals and advocacy. Perhaps big drops in launch costs and cheaper SBSP system designs will finally make it practical, especially for powering remote sites: How to Get Solar Power on a Rainy Day? Beam It From Space | WIRED

In October, the Air Force Research Lab announced a $100 million program to develop hardware for a solar power satellite. It’s an important first step toward the first demonstration of space solar power in orbit, and [long time SBSP proponent John Mankins] says it could help solve what he sees as space solar power’s biggest problem: public perception. The technology has always seemed like a pie-in-the-sky idea, and the cost of setting up a solar array on Earth is plummeting. But space solar power has unique benefits, chief among them the availability of solar energy around the clock regardless of the weather or time of day.

It can also provide renewable energy to remote locations, such as forward operating bases for the military. And at a time when wildfires have forced the utility PG&E to kill power for thousands of California residents on multiple occasions, having a way to provide renewable energy through the clouds and smoke doesn’t seem like such a bad idea. (Ironically enough, PG&E entered a first-of-its-kind agreement to buy space solar power from a company called Solaren back in 2009; the system was supposed to start operating in 2016 but never came to fruition.)
