silly story ideas, free to a good home:

  • political thriller set in a high fantasy world without technological stasis, so it’s got like 1990s technology
  • magical realist high fantasy: a fantasy world with rigorous magical systems and detailed worldbuilding where sometimes inexplicable shit happens simply because the emotional logic of the narrative demands it
  • elaborate hard-SF Larry Niven style except there’s also secret wizards hiding their existence from the rest of the universe (that the wizards did not in fact build the macguffin the plot is concerned with is a minor plot point)
  • postapocalyptic science fiction but the mood is farce
  • alternate history with a very carefully worked out single point of divergence, but also it’s magical realism and sometimes inexplicable things happen just because the emotional logic of the narrative demands it.
  • high fantasy, but the world not only has magic, but radically different mundane physical laws whose implications have been carefully worked out in the manner of a Greg Egan story.
  • contemporary urban fantasy but the story is literally just about wizards trying to run their own space program in secret
  • contemporary urban fantasy but the story is about the wizards from the previous story trying to run a space program in the parallel hell-dimension they discovered, because it has its own unique cosmological properties they’re fascinated by
  • urban fantasy but instead of being set in “our” world, it’s set in a world with radically different physical laws that are nonetheless worked out with diamond-hard realism, in the style of greg egan. but, you know. also with secret wizards.
  • who are running a space program
  • i’m gonna be real with you, if i discovered magic was real, and i personally was a wizard, my first thought would be, “how could i use this to advance the exploration of space?” i would settle for the exploration of the ocean or something in a pinch, but mostly i would be thinking about space

“high fantasy, but the world not only has magic, but radically different mundane physical laws whose implications have been carefully worked out in the manner of a Greg Egan story.”

I think I play in a TTRPG setting like this?

“contemporary urban fantasy but the story is literally just about wizards trying to run their own space program in secret”

this isn’t actually a scholomance fanfic I’ve seen but the characters in other scholomance fanfic have definitely discussed a secret moon colony

Europa & Io passing over Jupiter’s Great Red Spot, shot from space probe Cassini.

for everyone asking if this is real footage: yeah!

It is an extremely accelerated timelapse made by Kevin Gill, the movement here is more a matter of Cassini whipping past Jupiter at astounding speeds than the motion of the moons, which is why there’s such a large parallax shift, but it’s actual images taken during the Cassini flyby. They did another one of Titan orbiting Saturn, you can see that at the end of this video. [Flickr link]

How We Decided


The day after tomorrow- that is, February 18, 2021- the Perseverance rover will attempt to land on the surface of Mars.  It will enter the planetary atmosphere at an acute angle, giving it as much time as possible to experience drag and slow down from orbital velocities.  Because Mars’ air is so thin, and the rover is so heavy, this will fail- in the best case, Perseverance would still be going almost a thousand miles an hour when it impacts the surface.  To help save itself, the craft will deploy a parachute of advanced design, seventy feet across and able to withstand supersonic velocities.  This, too, will fail.  Even with a parachute, there is simply not enough air between Perseverance and the Martian surface to slow it down all the way.  So this is where the rockets kick in.  Once air resistance slows the rover to a bit less than two hundred miles per hour, the heavy heat shield will be jettisoned, and a system of secondary rockets will fire against the direction of motion until it slows to near-hovering.  In a final flourish, the rover will descend from the rocket-boosted frame on coiled springs, until it touches down in the western part of Jezero crater in the northern hemisphere of Mars.


As it happens, Perseverance’s destination was one of the very last things we decided about it- not until the craft itself was fairly thoroughly engineered and designed.  Formally, the decision was made by the mission directorate.  In practice, they follow the consensus of the scientific community, which in turn hashes things out at a series of open-invitation workshops.  Things began with a call for white papers- an open suggestion box, basically.  In 2015, the first workshop narrowed things down from thirty serious proposals to eight candidates.  In 2017, the second workshop further winnowed the list down to three.  And in October of 2018, after three days of presentation, debate, and discussion, the final workshop selected Jezero Crater from these final three candidates using a simple vote of all attendees, and passed on the recommendation to the mission leads.

I haven’t been in the business for very long, so the final workshop was the only one of these where I actually participated.  It wasn’t a close vote as such, and I didn’t break any ties, and technically we were just making a strongly worded suggestion.  Nonetheless, my vote is one of the reasons why the Rover will be going to Jezero Crater instead of Syrtis Major or Gusev, and I think I’m entitled to feel ownership of this mission choice, just a little bit.

(This is, of course, terrifying.)

Having gone through the experience, there were a few surprises worth noting.  The first was how small some of the numbers are here.  The conference was not very large: only thirty proposals, debated by just a few hundred attendees.  I’ve seen book review contests with more entries, and that are read by a wider audience.  Which is to say, this is a situation that was, and is, extremely responsive to individual effort.  In that small a room, populated by people that are philosophically committed to changing their minds when they see good evidence or a good argument, one person can stand up and change the future in a very real way.

The second surprise was the attendance requirements.  Or rather, the lack thereof.  The project is public, paid for by American taxpayers, to whom I am profoundly grateful.  And one way the process reflected that public-spiritedness is that this is not a walled garden.  A small attendance fee (iirc, $40?), and you’re in.  You get a vote, if you want to use it.  A few non-scientists even took us up on this; there’s one retiree (a former schoolteacher, I think) that’s attended every major conference I’ve been to in the last few years, and sets up a small table in the back with his home mineral collection just for fun.  In practice this open-door policy is limited by the obscurity of the event itself; if you don’t move in research circles, you have to be something of a space exploration superfan to hear about it.  Still, as symbols go, you could do worse.

And now that we’re coming up on the day itself, the same kind of public-facing mindset is making me think about why I was persuaded to vote for Jezero Crater, what it means to explore there, and how I’d justify that choice to those of you that made the ongoing discovery of Mars possible in the first place.

Not that anyone’s really keeping track, but I do think that this particular crater in the southern ice cap is the most beautiful (recent) impact on Mars.  HiRISE Image ID ESP_057152_0985, -81.485 latitude, 41.358 longitude, impact event in the late summer of 2018.  I keep coming back to it- the beautiful contrast against the ice, the way that the dark sediments of the ejecta blanket in the center almost form wings, the secondary ring of brighter ice all around it where the whoosh of air and dust cleaned the surface, the speckling of secondary impacts throughout.

One of my privileges as a student of Mars is that my object of study is not inhumanly large, or inhumanly small, or really very abstract at all.  The underlying theories can be, sure; geology isn’t stamp collecting.  But fundamentally, Mars is a place.  You can point to it, it’s over there, and sometimes we go to it.  The smaller dark speckles here are a meter or two across, the larger dark zone is maybe a couple football fields.  Roughly the size of a decent-sized mall parking lot, to walk across it.  Uneven going, since the rubble can range from dust to boulders, and especially towards the center you might clamber across using your hands as much as your feet at times.  You’d be cautious, since the exposed surfaces are so fresh- newly fractured rocks will surprise you with unexpected jagged edges, and even in the low gravity, stones are constantly shifting underfoot because nothing’s settled yet.  Ice pokes through here and there as you get near the outer perimeter, and when you look up from your study area it dominates the landscape, rows of small hillocks receding in to the distance.  It’s a crisp mix of water and carbon dioxide, rather pitted, with mottled patterns of red-black dust tracing across the surface.  Where it’s clean, it’s more of a matte white than you’re used to from snow on Earth, just enough to throw you a bit.  Especially as it picks up color tones from the alien sky above you: blue at the top of the sky’s arch near the sun, but phasing through soft purples to a dull red at the horizon.  The breeze is brisk, but gossamer; in the thin atmosphere, it can barely move the hairs on your arm, and the familiar sound of wind whistling over the rocks seems to come from far away.

Not really going anywhere with this post.  I just think about it sometimes, is all.
