From Titan's Doom Mons to Mercury's Pourquoi-Pas: how did the landscape of space get its names?

The Ordnance Survey recently made a very nice map of Mars’ Arabia Terra region. This map shows an alien crater-pocketed landscape, peppered with mysterious names like “Aram Chaos”, “Meridiani Planum” and “Marth”.

When the OS makes a map of Britain, it is making a map of a place with history – reflected in place names that come from the many different languages that people have spoken here. But where are the names on the Mars map coming from?

The romance of naming

Space used to be like the Wild West, with different names used by different people. So, in 1911, the International Astronomical Union started to become the official clearing house for space names.

It legitimised features from previous maps (like Schiaparelli’s map of Mars) and made rules for how new names would be picked. It now publishes its database online, and I used this and various NASA maps of other planets to build We Name The Stars – a way of exploring these rules and places.

The IAU conventions seem to understand that there is something magical and important about naming things. We don’t end up with Crater 62 on asteroid BXM-2: each kind of feature (mountains, ridges, craters, lakes) on each different world has a different naming convention, so that similar places are thematically linked. Often revolving around a particular ancient myth, this lends a sense of grandness and history to what is otherwise just some slightly different coloured pixels.

Not all names are mythical. Craters on Mercury are named after historically significant artists, while escarpments are named after ships of discovery. This is how you end up with a slope on Mercury named “Pourquoi-Pas”.

Craters on the asteroid Eros are named after “mythological and legendary names of an erotic nature” (which gives us Casanova and Abelard), while Saturn’s moon Titan has places named after mountains in Middle Earth. The largest mountain on Titan is called Doom Mons.

Places We’ll Never Go

Part of the appeal of the OS map is that it reinforces the idea of Mars as a place. It’s a technical challenge, but ultimately we understand how we’d get there, walk around, and get back.

Similarly you can vaguely imagine the 22nd century equivalent of the Arctic Explorer taking the journey my virtual rover is making across the Moon, visiting every crater. But there are plenty of other places to which we’ve given names that will probably never be walked on by people.

Take Mercury – it’s right next to the sun and spins very slowly. Every place on the planet spends every other month staring into the furnace. In several of his books Kim Stanley Robinson solves this problem with Terminator – a city that travels on rails around the planet. The sun heats the rails, which expand and push the city onward – permanently keeping it just beyond dawn.

But this is a fragile solution. Valleys on Mercury are named after ancient abandoned cities – a poor omen for the success of future settlement. Maybe maps of Mercury are for visitors, driving slowly to stay ahead of the sun.

Venus we can’t even visit. In the day the surface can get hot enough to melt lead, and the atmospheric pressure is the equivalent of being a kilometre under the ocean on Earth. On the other hand, it turns out that, if you build floating cities 50km up, the pressure and temperature are pretty much the same as on Earth. To our cloud-dwelling descendants it’ll probably seem odd that we put so many of our goddesses on features as unimportant to them as the floor of the ocean is to us.

There is something strange and wonderful about a system that produces such evocative names for places that in all likelihood no one will ever visit. These names don’t have to be pretty or coherent – but the effort is made anyway.

The European Sky

The IAU was founded at a time when “international cooperation” mostly meant “European cooperation”. The conventions emerging on using old myths and Latinised names were good, because that seemed like common ground.  Astronomers looked into space and then looked back on their shared classical heritage, pillaging the myths of the Romans and Greeks for important sounding but politically neutral names.

Except, of course, it’s not really neutral because not everyone comes from that heritage. Some 60 per cent of feature names are European in origin, and so European myth and history punches a little above its weight in the space naming race.

As the composition of the IAU has changed over time, this shift has been reflected in patterns for future names. Many conventions are now ecumenical: Io is littered with thunder and sun gods from different cultures, and Ceres has features named after the “agricultural festivals of the world”. Rhea uses names from “people and places from creation myths (with Asian emphasis)”; names on Triton are explicitly “aquatic names, excluding Roman and Greek”.

Fragile Monuments

But these are all faraway places, what about European domination of the places we’re actually likely to go – like the Moon and Mars? If the future of space turns out to be non-western, this issue ends up solving itself.

After the Chinese Yutu rover landed on the moon, the landing site was named Guang Han Gong (Moon Palace) and three local craters were given names from Chinese astrology by the IAU. When the asteroid 1998 SF 36 was selected as the target for the Japanese Hayabusa spacecraft, it was designated Itokawa after a Japanese rocket scientist. Where robotic feet go, naming rights follow.

On the Moon there are areas where naming is reserved to honour dead astronauts and cosmonauts, with the ominous note that “this convention may be extended if other space-faring countries suffer fatalities in spaceflight”. And why not? There’s plenty of Moon left, thousands of craters have been identified that have yet to receive an official name.

And even if a feature has a name with a history, will people honour it? Will a Martian Chinese colony in the Rutherford Crater still call it Rutherford? Will Indian settlers in Inuvik keep the name of a small town in Canada – or rename it something closer to home?

There’s a long history of name changes in space. British astronomers carried on with George’s Star (chosen by the discoverer of the planet to honour George III) for many years after everyone else switched to “Uranus”. The Galilean moons were once the ‘Medician stars’ – after the family whose patronage Galileo sought. When Cassini discovered the moons of Saturn he called them ‘the stars of Louis’ after King Louis XIV, hoping to create “a Monument much more lasting than those of Brass and Marble”. That we don’t use any of these names reflects the fragility of monuments that only exist on paper.

European myths may end up the Lingua Franca of empty places – only kept for areas to which no one has any interest in going. If in the future there are settlers in Arabia Terra, that OS map might be an interesting historical artefact for them – a perfectly correct map with all the wrong names.

What does the fate of Detroit tell us about the future of Silicon Valley?

There was a time when California’s Santa Clara Valley, bucolic home to orchards and vineyards, was known as “the valley of heart’s delight”. The same area was later dubbed “Silicon Valley,” shorthand for the high-tech combination of creativity, capital and California cool. However, a backlash is now well underway – even from the loyal gadget-reviewing press. Silicon Valley increasingly conjures something very different: exploitation, excess, and elitist detachment.

Today there are 23 active Superfund toxic waste cleanup sites in Santa Clara County, California. Its culture is equally unhealthy: Think of the Gamergate misogynist harassment campaigns, the entitled “tech bros” and rampant sexism and racism in Silicon Valley firms. These same companies demean the online public with privacy breaches and unauthorised sharing of users’ data. Thanks to the companies’ influences, it’s extremely expensive to live in the area. And transportation is so clogged that there are special buses bringing tech-sector workers to and from their jobs. Some critics even perceive threats to democracy itself.

In a word, Silicon Valley has become toxic.

Silicon Valley’s rise is well documented, but the backlash against its distinctive culture and unscrupulous corporations hints at an imminent twist in its fate. As historians of technology and industry, we find it helpful to step back from the breathless champions and critics of Silicon Valley and think about the long term. The rise and fall of another American economic powerhouse – Detroit – can help explain how regional reputations change over time.

The rise and fall of Detroit

The city of Detroit became a famous node of industrial capitalism thanks to the pioneers of the automotive age. Men such as Henry Ford, Horace and John Dodge, and William Durant cultivated Detroit’s image as a centre of technical novelty in the early 20th century.

The very name “Detroit” soon became a metonym for the industrial might of the American automotive industry and the source of American military power. General Motors president Charles E. Wilson’s remark that, “For years I thought what was good for our country was good for General Motors, and vice versa,” was an arrogant but accurate account of Detroit’s place at the heart of American prosperity and global leadership.

The public’s view changed after the 1950s. The auto industry’s leading firms slid into bloated bureaucratic rigidity and lost ground to foreign competitors. By the 1980s, Detroit was the image of blown-out, depopulated post-industrialism.

In retrospect – and perhaps as a cautionary tale for Silicon Valley – the moral decline of Detroit’s elite was evident long before its economic decline. Henry Ford became famous in the pre-war era for the cars and trucks that carried his name, but he was also an anti-Semite, proto-fascist and notorious enemy of organised labor. Detroit also was the source of defective and deadly products that Ralph Nader criticized in 1965 as “unsafe at any speed”. Residents of the region now bear the costs of its amoral industrial past, beset with high unemployment and poisonous drinking water.

A new chapter for Silicon Valley

If the story of Detroit can be simplified as industrial prowess and national prestige, followed by moral and economic decay, what does that say about Silicon Valley? The term “Silicon Valley” first appeared in print in the early 1970s and gained widespread use throughout the decade. It combined both place and activity. The Santa Clara Valley, a relatively small area south of the San Francisco Bay, home to San Jose and a few other small cities, was the base for a computing revolution based on silicon chips. Companies and workers flocked to the Bay Area, seeking a pleasant climate, beautiful surroundings and affordable land.

By the 1980s, venture capitalists and companies in the Valley had mastered the silicon arts and were getting filthy, stinking rich. This was when “Silicon Valley” became shorthand for an industrial cluster where universities, entrepreneurs and capital markets fuelled technology-based economic development. Journalists fawned over successful companies like Intel, Cisco and Google, and analysts filled shelves with books and reports about how other regions could become the “next Silicon Valley”.

Many concluded that its culture set it apart. Boosters and publications like Wired magazine celebrated the combination of the Bay Area hippie legacy with the libertarian individualism embodied by the late Grateful Dead lyricist John Perry Barlow. The libertarian myth masked some crucial elements of Silicon Valley’s success – especially public funds dispersed through the U.S. Defense Department and Stanford University.

The ConversationIn retrospect, perhaps that ever-expanding gap between Californian dreams and American realities led to the undoing of Silicon Valley. Its detachment from the lives and concerns of ordinary Americans can be seen today in the unhinged Twitter rants of automaker Elon Musk, the extreme politics of PayPal co-founder Peter Thiel, and the fatuous dreams of immortality of Google’s vitamin-popping director of engineering, Ray Kurzweil. Silicon Valley’s moral decline has never been clearer, and it now struggles to survive the toxic mess it has created.
