The Ethics of Martian Babies

Rand Simberg probes the issue over at PJM: The Bioethics of Mars One.

It’s funny to see Rand and the commenters on his article echoing the sentiments we present in In the Shadow of Ares regarding Amber’s parents having a child on Mars and the continued reluctance of other settlers to have children. One criticism we received from several early readers of the manuscript was that it was unlikely that in a dozen years of settlement activity, nobody else would have had a child but Aaron and Lindsay.

Well…here’s an indication that it’s not so unlikely.

Agriculture on Mars

Interestingly (or perhaps not surprisingly), we came to some of the same conclusions as these researchers. Of particular note, the morale benefit to settlers in an inescapably indoor environment of having an open green space (or Greenspace, if you’ve read the book).

An interesting project at the South Pole, involving agriculture in a controlled (and in this case, sunless and soil-less) environment: To the moon…South Pole greenhouse model for growing freshies on other worlds

Crops of lettuce, kale, cucumber, peppers, herbs, tomatoes, cantaloupes and edible flowers comprise many of the plants grown in the climate-controlled chamber. Because the importation of soil is restricted by the Antarctic Treaty External U.S. government site, dirt is not used to grow the plants. In fact, the closest local dirt is nearly two miles beneath the ice on which the station sits. The plants are grown in a hydroponic nutrient solution instead — no dirt needed.

For that matter, no sunlight is needed either. The growth chamber, which was built in the winter of 2004, makes its own light via 13 water-cooled, high-pressure sodium lamps. In this bright environment, it is not uncommon to find people, like the plants, dwelling happily under the intense light produced in the chamber during the dark polar winter.

Carl and I put a lot of thought into extraterrestrial agriculture while writing In the Shadow of Ares, not least because the primary setting for the book is a very large agricultural settlement. Interestingly (or perhaps not surprisingly), we came to some of the same conclusions as these researchers. Of particular note, the morale benefit to settlers in an inescapably indoor environment of having an open green space (or Greenspace, if you’ve read the book).

Farming in Space

Whether it is the fresh atmosphere of a small homestead garden or the large park tucked into one corner of an industrial-scale agricultural bubble, greenhouses will offer settlers a reminder of Earth and a break from their otherwise wholly artificial surroundings.

Popular Mechanics takes an ever-so-brief look at farming in space.

Gene Giacomelli, a University of Arizona agricultural researcher and the lead investigator of a NASA-funded growth chamber for the moon, envisions a multiarmed, inflatable greenhouse building staffed with robots that do the bulk of the work. “Astronauts should not have to be farmers,” he says.

Nor (more to the point) should settlers.

The settlers in In the Shadow of Ares make extensive use of this combination of inflatable greenhouses and robotic technology, in the form of the bubbles at the Green and the Jacobsens’ Ares IV homestead and their respective semi-autonomous gardener ‘bots.

While the article mentions food and oxygen production, it does not mention one of the important benefits such greenhouses would offer: enhanced morale. Whether it is the fresh atmosphere of a small homestead garden or the large park tucked into one corner of an industrial-scale agricultural bubble, greenhouses will offer settlers a reminder of Earth and a break from their otherwise wholly artificial surroundings.

Life Imitates Art: MAs and 5G

While looking at upgrading to a 4G phone/hotspot combo this afternoon I got to wondering if there was a “5G” in the works. It turns out there isn’t, exactly, but there are a few hints on the Wikipedia page on what that wireless standard might include when it emerges around 2020:

* Pervasive networks providing ubiquitous computing: The user can simultaneously be connected to several wireless access technologies and seamlessly move between them (See Media independent handover or vertical handover, IEEE 802.21, also expected to be provided by future 4G releases). These access technologies can be 2.5G, 3G, 4G, or 5G mobile networks, Wi-Fi, WPAN, or any other future access technology. In 5G, the concept may be further developed into multiple concurrent data transfer paths.

* Cognitive radio technology, also known as smart-radio: allowing different radio technologies to share the same spectrum efficiently by adaptively finding unused spectrum and adapting the transmission scheme to the requirements of the technologies currently sharing the spectrum. This dynamic radio resource management is achieved in a distributed fashion, and relies on software defined radio. See also the IEEE 802.22 standard for Wireless Regional Area Networks.

* Internet protocol version 6 (IPv6), where a visiting care-of mobile IP address is assigned according to location and connected network.

* High altitude stratospheric platform station (HAPS) systems.

* Real wireless world with no more limitation with access and zone issues.

* Wearable devices with AI capabilities.

* One unified global standard.

    Hmm…that “wearable devices with AI capabilities” business sounds awfully familiar…

    Given that new wireless communications “generations” come out approximately every ten years, the standard that emerges around 2050 — “8G” — ought to be pretty impressive.

    Concept Art

    While rooting around in a desk drawer this evening, I came across a bunch of sketches of our early concepts from 2002-2003 for several locations and bits of hardware for In the Shadow of Ares. It’s surprising how similar most of them were to what ended up in the book — and that only one specific setting ended up not making it.

    If I can get some time this weekend, I’ll scan them in, and in the case of the MA add a sketch of what the original concept morphed into over time.

    Move Over, Taco Bell, Here Comes Vat-Meat

    Walter Russell Mead sings the praises of those entrepreneurs who might one day bring us an environmentally-friendly and guilt-free source of protein: synthetic meat.

    Now I don’t know whether this particular technology will ever pan out, so that PETA activists will be stopping in at the local McDonalds for a tasty shamburger. Dr. Mironov might be wasting his time, or he might really be onto something.

    But the point is that there are hundreds of thousands of Dr. Mironovs working on all kinds of unconventional inventions and ideas in labs and garages all over the world.  Most of them may never produce very much but, especially with the tremendous advance of knowledge in biology of recent decades, some of them are going to get some very remarkable, life changing results.

    Whether we will get delicious juicy shamburgers and sinfully salty, crisp facon (fake bacon) anytime soon is beyond me.  But that the future will be full of surprises that change the basic rules of the energy game is almost certain.  This is why I don’t think the prophets of doom have it right.  Human ingenuity has been getting us out of tight corners and making life unexpectedly better for thousands of years; I don’t think we’re done yet.

    Those who have read In the Shadow of Ares already know of one possible market for this technology. Indeed, a grow-it-at-home version appears in the opening chapters of the book. If the technology works, and can be packaged into a reliable system with reasonable space and resource requirements, it would be a wonderful source of protein and familiar foodstuffs in an early Martian settlement, where raising livestock would be impractical for many years until sufficient habitable volume and related infrastructure had been established.

    Indeed, if it works well (by which I mean it produces something more palatable and less monotonous than just a synthetic form of Spam), the technology would eliminate the need to ever raise livestock on Mars…if anyone would ever seriously consider doing such a thing.

    Not Forgotten

    What would happen if a spacecraft and its crew were lost tens of millions of miles from Earth, where there were no ground-based cameras and radar watching, no clues from telemetry data, and no way to retrieve and study the wreckage?

    This week marks the 44th anniversary of the Apollo 1 fire, the 25th anniversary of the Challenger accident, and the 8th anniversary of the Columbia accident.

    Abandon in Place

    Each of these accidents were heavily publicized and widely mourned, with the latter two happening (essentially) live on television. Even though much time has passed, the accidents are well known to the general public, and even many people who are not space buffs could probably at least come close to identifying the official cause of each accident.

    In each case, though, the wreckage was retrieved and studied, lessons were (mostly) learned and put into practice, and the affected programs continued on. But what would happen if a spacecraft and its crew were lost tens of millions of miles from Earth, where there were no ground-based cameras and radar watching, no clues from telemetry data, and no way to retrieve and study the wreckage?

    This is exactly the problem which confronts the fictional Ares Project two decades before the events of In the Shadow of Ares. So how did they handle it?

    The program was halted for four years so that the habs and Earth-return vehicles under construction on Earth could be thoroughly inspected and their designs reassessed for hidden flaws. Finding none, and still having no solid evidence of what happened to the Odysseus and its crew, the project proceeded cautiously with the remaining two missions. And as it turned out, the program was right to accept the still-unknown risks inherent in exploration rather than give up and stay home.

    One big difference between then and then: with no images of the accident, and no wreckage found by the subsequent missions, the public soon forgot about Ares III. Except for a few who kept the memory alive until an answer could be found…

    (For those who have read the book and may be wondering, we devised Odysseus‘ demise exactly fifty weeks before Columbia met her own.)

    The Mysterious Mr. Rana

    There’s more to Rajiv Rana than we let on in In the Shadow of Ares.
    What could he be hiding? And how did he really break his nose?

    There’s more to Rajiv Rana than we let on in In the Shadow of Ares:

    He paused, then added simply, “You’re quiet today.”

    “Am I?” she asked coolly as she pulled on her immersion goggles and rings.  You’re part of it.  Margolis said so herself.  I know you’re hiding something.  That’s why none of the Green’s survey data from the past two years is available.

    “Yes, you are,” he replied, noting the tone in her voice with a slight narrowing of his eyes.  “But, if you don’t want to talk to me, well, that’s okay.  We can talk again when you’re in a better mood.”

    She yanked off her goggles and turned to face him.  “What makes you think I’m in a bad mood?”

    He shrugged.  “Your…moodiness?”

    “What?  Oh.  Well, maybe I am mad.  Shouldn’t I be?  I know you’re hiding something…” She stopped short when she saw his face suddenly become an expressionless mask.

    There was an uncomfortable pause.  “Hiding?” he asked cautiously.  “What is it you think I am hiding?”

    “I…uh…”

    His dark eyes bored into her own.  “Go on.”

    Me and my big mouth. “The, uh, the cavern…”  If possible, his face became even more expressionless when she mentioned the cavern.

    “The cavern?  What is it you think I am hiding about a cavern?”

    Think fast. “I, uh, I know you’re hiding something down there.  There’s…  something down there, isn’t there?  That’s why Grantham won’t let anyone go in?”

    “Oh, that again.”  Rana pursed his lips and rolled his eyes.  The tension between them seemed to evaporate suddenly.  A little too suddenly, perhaps.

    What could he be hiding? And how did he really break his nose?
