Martian Technology: Science Pins and Pingers

These devices have been featured so far in In the Shadow of Ares and quite prominently in Redlands and He Has Walled Me In.

A science pin, as described in ItSoA, is a device shaped like a scaled-up golf tee, with a stem 1-1.5m long, and a head 100-150mm across and anywhere from 50mm to 400mm tall. The stem contains common power generation, storage, and management functions, and in the field is mounted to a peg or sleeve drilled or driven into the soil or rock.  The head consists of one or more cylindrical modules of different heights and a wide variety of functions. These modules thread together at the center with a common physical and electrical interface.

In all applications there is a communications and C&DH (command and data handling) module. This module links the pin to local and satellite communications networks, as well as to specialized instruments such as seismometer arrays or deep soil probes which are not located on the pin itself.

Modularity and standardization make it possible for science pins to be quickly emplaced and easily maintained, and readily upgraded with new or additional instruments as needed. The size and external features of the modules make them easy for suited settlers to handle with gloved hands.

Lindsay Jacobsen is shown in ItSoA maintaining a science pin she had previously deployed to monitor ground water for evidence of biological activity.

In HHWMI, Leon Toa has a strange encounter with a strange science pin in the Wilds.

Redlands prominently features a gold-plated science pin, and the action is set at one of the settlements where the devices are manufactured.

In Ghosts of Tharsis, we introduce a specialized application of the science pin concept, the “pinger”. A pinger is a science pin used as a navigation aid, particularly during mild to moderate dust storms when travel by rover is still somewhat feasible. The head of a typical pinger is a single mass-produced module containing navigation strobes and the power storage required to operate them for a month or more. The head is crowned with a passive reflector that rover navigation radars can use for distance and triangulation measurements.

Pingers at intervals and in problem-prone locations include additional instruments to monitor local weather conditions and transmit them back to a central data hub for use in travel planning.

I particularly liked the idea of reusing science pin components as the basis of navigation aids, as it reflects a potential real-world solution to the problems of navigating across a landscape with minimally-developed roadways prone to obscuring by dust. It has the added benefit of eliminating the ability of the MDA to bring to a halt surface transportation among the independents by scrambling the signals from the positioning satellites on which they have a Charter-granted monopoly. But most importantly for our purposes as authors, it makes possible a dramatic rover chase in a Class 1 dust storm…

Looking Back from Mars

Netflix’s Mars series “Away”, starring Hilary Swank, debuts next month.  Check out the official trailer.  It appears to focus on the relationship of a mother leaving behind her daughter for a 3-year mission.

What caught my eye was the Earth-Moon-Mars bracelet Swank’s character gives her daughter prior to departure.  Not nearly as cool as Amber’s pendant in In the Shadow of Ares, but still an interesting parallel between the two stories.

Here, Hold My Beer

NAWA Technologies has announced that it will begin mass-producing carbon nanotube based ultracapacitors.  Compared to lithium batteries, ultracapacitors are capable of near-instantaneous charging and discharging.

It was these characteristics that led us to select this technology, in our novel In The Shadow of Ares, to power various devices on a future Mars, ranging from mobile agents to the autonomous “diggers” (mining robots).  More specifically, it was the near-instantaneous discharge of huge quantities of energy that made them particularly appealing.

Although the 2019 versions of ultracapacitors have shortcomings (low energy density and high leakage rates compared to lithium units), it is rewarding to see the technology we described a decade ago reach mass production.

So what say we buy one, bring it to full charge, and see what happens when we damage the charge regulator?

Survival and Sacrifice in Mars Exploration

This sounds interesting, if a bit pricey, like a cross between Big Dead PlaceEndurance, and The Martian (and who knows, probably a bit of Alive! thrown in as well).

Survival and Sacrifice in Mars Exploration: What We Know from Polar Expeditions  [Erik Seedhouse]

With current technology, a voyage to Mars and back will take three years. That’s a lot of time for things to go wrong. But sooner or later a commercial enterprise will commit itself to sending humans to Mars.

 

How will the astronauts survive? Some things to consider are:

• Who decides what medical resources are used for whom?

• What is the relative weight of mission success and the health of the crew?

• Do we allow crewmembers to sacrifice their lives for the good of the mission?

• And what if a crewmember does perish? Do we store the body for return to Earth or give the member a burial in space?

Questions like these, and hundreds of others, have been explored by science fiction, but scant attention has been paid by those designing missions. Fortunately, the experience gained in polar exploration more than 100 years ago provides crews and mission planners with a framework to deal with contingencies and it is this that forms the core of this book.

Why the parallels between polar and space exploration? Because polar exploration offers a better analogy for a Mars mission today than those invoked by the space community. Although astronauts are routinely compared to Lewis and Clark, Mars-bound astronauts will be closer in their roles to polar explorers. And, as much as space has been described as a New Frontier, Mars bears greater similarity to the polar regions, which is why so much can be learned from those who ventured there.

Note that even though we’ve written young-adult SF, we haven’t shied away from these sorts of questions, and indeed In the Shadow of Ares opens with the death of the entire third expedition to Mars, which mystery forms the core of the novel. Likewise, a dramatic mass-casuality accident forms the background of our new short story, He Has Walled Me Inand the story itself has origins in my having read Laurence Gonzales’ Deep Survival.

 

RIP Phobos

PhobosThat may be a bit premature, but apparently Phobos will be pulled apart by Mars’ gravity in about 30 to 50 million years.  New findings were announced by NASA Goddard scientists November 10.

Phobos’ grooves, long thought to be related to the enormous impact that created Stickney Crater, may actually be due to deformation from tidal forces.  These “stretch marks” may indicate that Phobos is not solid, but rather is an aggregate of rubble surrounded by a thick layer of powdery regolith.  This would make it easier for tidal forces to fracture the Moon.

These findings, if accurate, could present interesting challenges and opportunities for astronauts visiting the moon for exploration, mining, or setting up a base.  Phobos will figure prominently in Ghosts of Tharsis, our upcoming sequel to In the Shadow of Ares.

 

 

 

Review – The Martian

I finally got to check out The Martian this afternoon.  I thought it was fantastic, as did the family members with me, young and old.  It has all the great imagery and action sequences that I go to the movies for.

It’s a while since I read Andy Weir’s book, but based on my recollection I felt the movie was true to the story in all the right places, and better in some.  Mark Watney is MacGyver on Mars.  The detailed technical exposition is largely gone, but that would have bogged down a film that was already 140 minutes long.  For the most part the profanity was limited, probably another good change to increase the broad appeal of the film.  Drew Goddard’s screenplay also did an adequate job of fleshing out the secondary characters, something on which I felt the book fell short.

As far as accuracy goes, just as in the book the effect of winds on Mars was completely unrealistic.  The author admits as much, using it as a necessary plot device.  I was a bit disappointed in the surface suits.  They are visually appealing, and they look more like a next generation suit than a standard pressure suits, but they were clearly not as tight fitting as a true mechanical counter pressure suit (as we depict in In the Shadow of Ares) would be.

For a couple of extra space-centric reviews you can check out Keith Cowing’s review here (with a NASA-focused perspective) as well as Sarah Lewin’s review on Space.com here.

As for my previously expressed concerns regarding what kind of a message The Martian would have, those were put to rest.  By necessity the movie focuses on the hardships of living on Mars, and surviving in space in general, but it’s also a celebration of exploration and challenge.  In one scene, while resigned to his own death, Mark Watney asks that his family be told that he died doing something he loved, for a cause that was bigger than himself.  Amen.

Movie Science: Does it Matter if It’s Wrong?

Thursday I attended my second presentation in as many months at the Lunar and Planetary Institute near the Johnson Space Center south of Houston.  It was part of their Cosmic Explorations lecture series, titled “Movie Science:  Who Cares if It’s Wrong?”, and consisted of a talk by Dr. Seth Shostak, Senior Astronomer and Director at the SETI Institute.  He is also host of the Big Picture Science radio show and podcast.

Dr. Shostak gave an entertaining presentation on scientific accuracy in film, from the perspective of a scientist asked to provide guidance on Sci-Fi scripts.  Provided and often ignored.  We were given humorous insight on the creative process, where Hollywood gets it right sometimes but often not.  It was ultimately left up to the audience to decide if it ultimately matters.  Of course with In the Shadow of Ares, and the sequel, we’ve taken the position that it does.

It is anticipated that the series will pick up again starting in the fall.  Those living in the Greater Houston area and interested in attending should check the LPI website in August/September.

See? We Told You So

Forbes has a short piece on the ethics and practicalities of having babies on Mars: Birthing Babies On Mars Will Be No Small Feat.

They cover the core reasons why having children (at least for the first fifteen or so years of settlement activity) is a taboo in the Ares Project universe: mainly, there’s no telling whether it will be safe to do so, and in small commercial settlements, babies and small children will consume scarce economic resources without near-term economic return. This originated early on in writing In the Shadow of Ares in the need to explain why Amber Jacobsen was still the only child on Mars after almost fourteen years of settlement activity, and the more we thought about the reasoning behind such a taboo the more real-world sense it made (and the more influence it had on her character and the story, especially the coming-of-age subplot).

Of course, in Ghosts of Tharsis and “He Has Walled Me In” we show that this taboo is starting to break down. This happens in large part because several of the settlements are large enough by the time these stories take place to absorb the economic impact.

Review: Interstellar

Interstellar - GargantuaI’m posting this review of Interstellar, belatedly, because I felt I had to see it again before commenting on its greatness as well as its few shortcomings. There was just too much to absorb and appreciate in one viewing. I’ll be careful with my wording to avoid spoilers.

Knowing the basic premise— explorers are searching for a habitable home for humanity to save them from a dying Earth, helped by unknown, advanced “bulk beings” who have opened a wormhole near Saturn for our use—I had initial trepidation that I was in for a Climate Change lecture. That notion was dispelled on the first viewing. Sure there’s a dust-bowl type blight that is wiping out crops and threatening what’s left of mankind; but this is just the impetus—the McGuffin if you will—to provide the urgency that drives the action. Some elements leading up to the climax were a bit too contrived for my taste, but overall it’s a great story with a strong cast, tension, and visuals that won’t let anyone down.  The script is excellent, with the exception of one criticism I’ll go into below.

Unlike so many recent Sci-Fi films, this one consistently makes a case for space exploration and advancement. A particularly powerful and effective scene involves a parent-teacher conference where Cooper has to process the absurdity his daughter’s suspension. Murphy’s transgression? She got into a fight after bringing a non-sanitized textbook to school; one that hadn’t been “corrected” to show that the Apollo landings were an elaborate hoax.

Cooper: You don’t believe we went to the Moon?

Teacher: I believe it was a brilliant piece of propaganda, that the Soviets bankrupted themselves pouring resources into rockets and other useless machines…

Cooper: Useless machines?

Teacher: And if we don’t want a repeat of the excess and wastefulness of the 20th Century then we need to teach our kids about this planet, not tales of leaving it.

Cooper: You know, one of those useless machines they used to make was called an MRI, and if we had one of those left the doctors would have been able to find the cyst in my wife’s brain, before she died instead of afterwards, and then she would’ve been the one sitting here, listening to this instead of me, which would’ve been a good thing because she was always the…calmer one.

Wow, not the kind of thoughtful dialog you expect in a film like this, but most welcome and expertly delivered.  It’s something we were keen to include in In The Shadow of Ares, and what is so often missing from the anti-human, Luddite drivel we’ve come to expect.  The humor is also excellent, particularly the interaction between the humans and robotic character TARS.

Where I was a little let down by the dialog was during the climax where Cooper solves the mystery of the bulk beings.  Cooper works out the details in a conversation TARS that is perfectly set up to avoid exposition, yet ends up feeling like just that.  Complicated conclusions end up being stated more than worked out. This important scene, and the accompanying dialog, could have been extended slightly and improved greatly.  I have my fingers crossed that this is addressed in the Director’s Cut.

While Interstellar is brilliant on so many levels, it’s the human element that really surprised me.  Ultimately it’s a story about our relationships and obligations to those we love, particularly our children.  Two scenes in particular, between Cooper and Murphy, are perhaps the most powerful I have ever seen.

Review: The Martian

I recently finished The Martian by Andy Weir.   I knew little about it, hadn’t read any reviews, and wasn’t expecting much.  In fact, I was ready to be disappointed. 

When we decided to write In the Shadow of Ares, we intentionally set it on a developed Mars.  For my part, I thought the story of a few astronauts and a dead planet had been done to death, with predictably mediocre results. 

I’ve never been so wrong.  This book is fantastic. 

Mark Watney is stranded on Mars when the rest of the Ares III crew have to evacuate for Earth shortly into their mission.  He is thought to be dead, and with no functioning communications and almost no food, his prospects are bleak. What he does have, though, is a mountain of ingenuity and a great sense of humor that give him a fighting chance.

The Martian is highly technical, but so funny and suspenseful that it should be accessible to nearly anyone (the language is genuine—and salty—so it’s not for all). Despite the bulk of the story consisting of the narration of the protagonist, the voice of that character is more than strong enough to carry the story along, and it doesn’t hurt that the pacing and suspense are outstanding.  I did have a few technical and editorial criticisms, but they are too insignificant to describe in detail here.

This is one of the most creative and enjoyable books I have ever read, and I recommend it highly.
