Dating Artemis: An Astronomical Sci-Fi Mystery Solved?

On sale now.

I love it when a hard science fiction book presents an astronomical mystery.

I came across just such a mystery reading Artemis, the latest science fiction novel out late last year from Andy Weir.

Artemis presents the story of Jasmine Bashara, a young girl trying to make her way in the first settlement on the Moon. Artemis is a thriving town, built around Earth tourism at the Apollo 11 Sea of Tranquility landing site.

We won’t introduce any spoilers here; suffice to say, if you like some hard science blended into your fiction, you’ll love Artemis. Like The Martian, Artemis also seems to be near-future science fiction, both culturally and technologically. We say “near” as in something that’s plausible over the next half-century or so. Also like The Martian, Artemis doesn’t peg the exact date when the events transpire… or does it? As an amateur astronomer and avid sky watcher, I noticed a few clues that just might pin down the exact future date of the tale.

Dating the Martian

Weir puts lots of research into his novels. With The Martian, he states that if you can work out the Hohmann transfer windows between the Earth and Mars needed for the Ares III mission to rescue and return Mark Watney back to Earth, then you could pin down the date in the 2030s when the events in The Martian transpired.

Is there a similar puzzle in Artemis? Well, I think there could be, based on you key celestial sights mentioned in the book.

Artemis runs on Kenya Time, as missions headed to the Moon depart from the equatorial country, taking advantage of its maximum rotational boost eastward and its favorable laws encouraging space companies to set up shop there. Kenya Time is Universal Time, +3 hours.

The most conspicuous objects in the sky as seen from the Apollo 11 landing site are the Sun and the Earth. “Daytime” on the Moon lasts about two weeks from sunrise to sunset… but the Moon is locked with one hemisphere turned perpetually Earthward, so the Earth would never set. Instead, Earth would go through phases like the Moon does as seen from the Earth, as it slowly circles a spot high in the sky due to the rocking nutation and libration motion of the Moon.

The phases you see from the surface of the Moon, however, are opposite to what you see on the Earth. This means when the Moon is Full from the Earth, Earth is at New as seen from the Moon. Likewise, waxing versus waning phases are reversed.

Artemis gets these phases right where it makes mention of them. On their own, however, one cycle of phases is pretty much like another… even making mention of something like an eclipse wouldn’t really pin the date down, as several lunar and solar eclipses happen, every year.

We get a possible lead, however, from the following passage when the protagonist checks her Earth-phase watch:

”Lene checked her wristwatch. ‘Ten thirteen a.m…and there’s currently a half-Earth, by the way. It’s waxing.’”

Now, that’s a little more specific… converting 10:13 AM Kenya Time to 7:13 Universal Time we just need to reverse the phase, and find when there’s a waning Last Quarter (half) Moon seen from the Earth around the same time.

Combing through the Astro-Pixels listing of Moon phases for the 21st century for Last Quarter Moons that will fall on 7:13 UT plus or minus one minute , I came up with the following possibilities:

August 30th, 2021 (it’s not likely that there’ll be a lunar outpost in just over three years!)

August 9th, 2099 (more likely).

Of course, a few caveats are in order. Phases such as New, Full and Quarter are only instants in time. You could look up at the Moon (or the Earth, from the surface of the Moon) several hours one either side of Quarter phase and it would still appear pretty much half-illuminated. I own a Casio watch that shows the current phase of the Moon, for example… but it would be hard to pin down the exact moment of the Full or Last Quarter Moon with just the watch display alone.

Is the passage a true “tell” planted by the author? Maybe, maybe not. There are other methods the author could’ve used that are even more exact. Transits of Mercury and Venus across the face of the Sun, for example, are also visible from the surface of the Moon. On November 12th, 2190, for example, Mercury will transit the Sun, just hours from a solar eclipse… and if you’re visiting the Apollo landing site on November 13th, 2236, you can see Mercury transit the face of the Sun, during an eclipse:

Perhaps, future celestial phenomena will make their way into an Artemis sequel?

Review: Raining Fire by Rajan Khanna

On sale now…

There’s one small plus to the current worldwide wave of jingoistic nationalism currently sweeping the world: dystopian science fiction is sure to do really well. Science fiction tends to reflect the hopes and fears of contemporary society, and you can often chart the swing from a shiny white, Star Trek outlook, to a fighting over gasoline, Road Warriors doomsday vision by the fiction we create and consume.

One fine new addition to the dystopian genre is this past summer’s Raining Fire by Rajan Khanna. Out now from Pyr Books, Raining Fire features a horror vision world wracked by a global pandemic, which has reduced humanity to squabbling tribes. Airships and floating city tech provides a backdrop for a brutal drama of slavery and Feral humans driven insane and violent by disease, a sort of steampunk world thrust forward into a desperate future vision.

It’s against this formidable world that we meet Ben Gold, an airship pilot with nothing left to lose. Already stripped of his airship, his allies and his friends, Ben is definitely looking for payback. He also lost Miranda, the only true love of his life, and the story is speckled with diary and journal entries from her that gradually paints a picture of what has come before.

In the end, Ben must face off against the Cabal, a group of sinister scientists (why are scientists always sinister in scifi tales?) and the Valhallans, who are wreaking continent-wide havoc from the flying city of Valhalla.

A high functioning alcoholic, Ben is the archetypal reluctant hero, a man who’s drinking hasn’t quite caught up to him… yet. Raining Fire has lots of action, and is a great portrayal of a man pushed past the edge.

Be sure to read Raining Fire as a great addition to modern dystopian science fiction!

There’s lots more dystopian science fiction to be had… here are some of our faves:

-Earth Girl: This was a gem of a story a out few years back. Imagine getting exiled to the worst place of all: living back on ancient Earth.

-The Hunger Games: A classic… true story, the wife and I both read the books after we saw the first movie, a very rare occurrence. We usually feel that seeing the movie let’s us off the hook (think Lord of the Rings) from saying we’re going to get around to actually reading the books… someday.

-Stand on Zanzibar: A trip of a book, straight out of the groovy 1960s.

-1984: Everything you need to know about the 20th century, in one book.

-The Crossing: Blood of the Lamb: A scary world to contemplate.

And speaking of scary dystopian fiction, be sure to check out Hulu’s amazing adaptation of A Handmaid’s Tale… this one’s all the more frightening because it hits so close to home and the current political climate. I think I’d much rather live in a future with ravaging airships than a world with the brutal and callous repression of personal liberties depicted in the series.

The Armageddon on Tap was pointed back with its stern sunward and was now parked at the Terra-Luna system’s far L2 Lagrange point. The repaired sunshield was now deployed, giving Karl and the Shrink a small shaded micro-environment in which to operate. They both moved slowly forward, despite their bulky spacesuits. Valkyrie and V.I.C.A.R. were visible through the cabin’s plexi-glass viewport. The large, nickel-iron asteroid seemed suspended above them in the ship’s capture cradle. [Read more...]
