Martian cartography: How Ordnance Survey mapped Mars

The world’s oldest mapping agency has turned its expertise to the Red Planet, with impressive results. But how do you map the surface of a planet 48 million miles away?

It’s been Britain’s best-loved mapping agency for years, providing navigation tools for organisations and stubborn dads finally pulling U-turns across the country.

Now, Ordnance Survey (OS) has taken its next giant leap for mapkind, creating a digital recreation of Mars that could have potential applications for future space missions.

Created using NASA open data, the map covers a 3672km x 2721km chunk of the Red Planet, has been produced to a scale of 1 to 4 million and even features a few of Mars’ scarce landmarks rendered in OS’ familiar style.

Mapping Mars

You might think that charting somewhere visited only by curious rovers and a bewildered Matt Damon would be a new challenge, but not so. At least not according to Chris Wesson, the map’s creator, who told Factor that after some trepidation the process bore surprising similarities to any other mapping task.

os-map-mars-1“To be honest, I didn’t really know what I was getting myself in for. I had no idea what was going to be sent to me, what format the files would be in, or whether the process would be completely different from the one that we usually do,” he said.

“I was quite pleasantly surprised to find out that even though it was a lot more interesting than usual – in the aspect that it was completely different to the data we tend to capture just in terms of the landscape – actually in terms of using it, it was incredibly similar. Certainly, the theoretical side of how we assembled a map is exactly the same as we would do for any OS mapsheet.”

That’s not to say that mapping the stars wasn’t a little alien to the company, whose first map of another planet is also its first outside British shores since the mid-90s.

“The landscape did present a few issues; it’s a rather rough and uneven surface, and the fact that there’s no features on the surface that we would recognise on an OS map such as woods and water and roads and railway tracks and paths – that definitely made it a lot more difficult to get to grips with,” Wesson added.

Technology-assisted cartography

Today’s world is certainly one that’s more mapped than ever. OS itself is sitting on a database of more than 450 million geographic features with up to 10,000 more added every day, and scarcely a week goes by when joggers aren’t being papped by a speeding Google Street View car.

With this in mind, does Wesson think technology has made mapping any easier?

“It might have got quicker and more efficient, but it may not necessarily become easier,” he said. “I guess where its comparable on the Mars map would be actually labelling the contours. There’s lots of software out there that will automatically label contours, but it won’t be anywhere near as good as the cartographers used to do them manually.

“Its almost as if it gives a shortcut to get there, but then we end up having to sort out any things that are not as they should be afterwards. There’s still a lot of improvement that could be made.”

That said, Ordnance Survey certainly knows its way around a challenge. The company’s past projects include transforming Scottish mountain Ben Nevis into a VR gaming experience for the Oculus Rift, and it’s now said to be involved in a £20m government-sponsored project to make Great Britain a world leader in driverless vehicles.

Traversing the Red Planet

Similarly, the OS Mars map could lead to all kinds of out-of-this-world applications. So says Peter Grindrod, a scientist at Birkbeck, University of London, who is currently assisting with landing plans for the European Exomars rover on Mars in 2019.

He told Factor he requested the map as part of an experiment into whether it  could be used for future Mars missions, and why OS would be best for the job.

“OS-style maps are remarkable things – they convey a huge amount of information that is both clear and attractive. Being able to use the same OS-style for future Mars maps means that we would hope for a similar effect,” Grindrod said.

“For example, future rover missions could have their traverses mapped on a detailed OS base map, with an elevation resolution almost the same as those we have for the Earth.

There’s ultimately no reason I can see at all why someone would not be able to do the same things with the Mars map as they can in the British countryside

“It’s my hope that such traverse maps would then be useful to both the scientific community and the general public, because of the OS mapping style demonstrated here.”

Ordnance Survey are hardly the first to map mars – just this month NASA released a 360-degree video that gave viewers the chance to potter about the planet’s surface from a rover’s perspective – but Wesson agrees that it’s the clarity of the agency’s maps that make them a potentially valuable resource for space exploration.

“A lot of people have seen an OS map at some point in their lives so a lot of people can relate to them, but it’s also about the way we present the information. We tend to present things in a less scientific fashion to the other maps of Mars.”

With claims from SpaceX CEO Elon Musk that humans could be on Mars in around ten years, it’s no surprise that Wesson has given some thought to his map being the one being used to venture across its surface.

“The fact that there could be people could be walking around on the surface of Mars –all that sort of thing was sort of exciting so that’s why we took it up,” he said.

“There’s ultimately no reason I can see at all why someone would not be able to do the same things with the Mars map as they can in the British countryside.”

Given that NASA has reportedly pushed its estimated date for human landings on Mars to 2035, it may actually be a bit longer before we’re trekking across the fourth rock from the sun. However, if Ordnance Survey’s map has potential, we’ll be more than ready to show ourselves around.

Scientists implant device to boost human memory

Scientists have enhanced human memory for the first time with a “memory prosthesis” brain implant. The team behind the device say it can boost performance on memory tests by up to 30%, and a similar approach may work for enhancing other brain skills, such as vision or movement.

Astronomers discover Earth-sized world 11 light years away

A planet, Ross 128 b, has been discovered in orbit around a red dwarf star just 11 light years from the Sun. The planet is 35% more massive than Earth, and it likely exists at the edge of the small, relatively faint star's habitable zone even though it is 20 times closer to its star than the Earth is to the Sun.

An algorithm can see what you've learned before going to sleep

Researcher fed the brain activity from sleeping subjects to a machine learning algorithm, and it was able to determine what the subject had learned before falling asleep. In other words, an algorithm was able to effectively ‘read’ electrical activity from sleeping brains and determine what they were memorising as a result.

Elon Musk unveils Tesla Truck and Tesla Roadster

Elon Musk has unveiled the long-anticipated 'Tesla Semi' – the company's first electric articulated lorry. The vehicle has a range of 500 miles on a single charge, and will go into production in 2019. Unexpectedly, Tesla also revealed a new Roadster, which will have a range of close to 1,000km (620 miles) on a single charge and will do 0-100mph in 4.2 seconds.

Boston Dynamics' Atlas robot can now do backflips

It's been a busy week for Boston Dynamics, first the company revealed it SpotMini robot dog was getting an upgrade, and now the company has shared a video of its Atlas humanoid robot leaping from platforms and doing a backflip. It seems like an obvious thing to say, but it's not easy to make a robot do a backflip, so how Boston Dynamics has managed it is anyone's guess.

The all new Factor Magazine is here – your guide to how today, tomorrow and beyond are being shaped

Guess who’s back, back again.

It’s been a few months, but Factor has returned with a bigger and better format, bringing the same future news and discussion, but on a platform that you can read on any device.

We’ve been working towards this for a long, long time: this is how we’ve always wanted the magazine to look, and we’re so happy to share this with you. It can be viewed on any web browser, on anything from a mobile to a monster PC, and if you’re on a desktop or laptop, click the button in the bottom right-hand corner for the ultimate shiny reading experience. A digital magazine has never looked this good. Probably.

Unfortunately that means no more iPad app, but as you can easily read the magazine from an iPad web browser, we hope you’ll agree that what we’ve gained is so much better than what’s been lost.

So anyway, here it is: the Winter 2017 issue of Factor, the first issue of the quarterly version of the magazine.

In case any of you are worrying about us publishing the magazine quarterly, trust us you don’t need to. We’ve produced the biggest issue of Factor ever, so packed with futuristic awesomeness, that we’ve had to divide it into three sections: Today, Tomorrow and Beyond.

Today deals with the futuristic present, as much of what we think of as ‘the future’ already exists today. We look at how humanoid robots are being employed as co-workers, hear from the legendary Richard Stallman about the vanishing state of privacy and discover how automation is already taking jobs. Plus, we take a light hearted look at the futuristic world of Mr Tesla, Elon Musk, and provide our festive present suggestions in a bumper futuristic gift guide.

Moving on to Tomorrow, and it’s all about the world of the next few decades, as technologies that are in development now reach fruition and seep into our everyday lives. We consider how flying cars are inching towards reality, with a look at both Lilium and the newly announced UberAir, and find out how driverless delivery may be the first true instance of the self-driving future.  Plus, we also look at the Christmas dinners of the future, because why the hell not.

Finally, in Beyond we look at the way-out future that many of us probably won’t live to see, but is supremely cool to think about. We ask leading futurists to predict what’s in store in the 22nd century – not the most positive of pictures, unfortunately – and consider what jobs will remain in a post-automation world. Plus, we look at the potential first homes of the human race beyond the solar system, and check out how asteroid mining is set to shape off-earth development.

Take a look, and if you like what you see and read, please share the magazine with your friends, or tell us what you think. This is a completely free magazine, with not an ad in sight, so it’s always good to know that it’s worth the effort.
