Oh, this is just delightful:

Here there be robots: A medieval map of Mars

Recently I’ve been really into old maps made by medieval explorers. I thought it would be fun to use their historical design style to illustrate our current adventures into unexplored territory. So here’s my hand-drawn topographic map of Mars, complete with official landmark names and rover landing sites.

Go check out the whole thing, but here’s a glimpse of the map itself (which is much larger on the original post):

 

You can even support the artist and buy a copy! Quick, before they’re all gone!

Having artists and writers involved in space research and planning? What will they think of next?

A good friend (and fan of Communion of Dreams), passed along an article which made me chuckle. Here’s an excerpt:

Earlier this month, the White House’s Office of Science and Technology assembled a strange gathering: scientists, artists, engineers, and policy-makers, for a workshop designed to imagine how humanity could settle the solar system.

The workshop, held in early February, was titled Homesteading in Space – Inspiring the Nation through Science Fiction, with the express purpose of imagining how manned space efforts can take us to our neighboring planets, not just for a short visit, but for longer durations.

And she added this comment with the link: “The group gathered reminds me a lot of your group from COD.

Ayup. Here’s the relevant passage from Chapter 1:

“I’ve had my expert do a preliminary search through the old NASA archives. I recalled that they had protocols for dealing with such possible situations, and I doubt that anyone else has really thought much about it since the turn of the century.

“In addition to Don’s field team, the preliminary search suggests that another component should be theoretical, a mix of disciplines so that we can get as broad a spectrum of experience and mind-set as possible. Probably we should have an expert in computer technology. A cultural anthropologist. Someone with a background in game theory and communication strategy. An artist or two. We’ll see if a more thorough survey of the NASA material has any good suggestions beyond that. I’ll get to work identifying appropriate individuals.”

And here’s a discussion the chosen artist (Duc Ng) has with the team leader in Chapter 4 about why it’s a good idea to have such non-technical people included in any such group:

“Why do you have an artist on this team?” asked Ng.

“It was a recommended protocol in some of the old NASA guidelines. Artists have a broader perceptual framework, aren’t necessarily limited by ‘logical possibilities’.”

“And what does that mean to you?” Ng leaned across the table. “That I’m just another kind of sensor you can use? Think about it. Those folks at NASA may have had something else in mind.”

Jon paused with his breakfast. “Go on.”

“How about if intuition and creative insight are the guiding principles of the culture that created the artifact? Not just a technological culture with its unique aesthetic sense, but a culture of intuitives who eventually produced sufficient technology to create this thing. A culture just the obverse of our own: largely artistic, with a secondary interest in technology.”

“With only a secondary interest in technology, how could they ever become a space-faring race?”

Ng shrugged. “Who knows how long they had been at it? Their culture may be tens of thousands of years old. Even a very modest rate of technological development could have led them into space eventually.” He paused, sighed. “Look, my point is that we can’t get stuck just looking for a technological explanation. The very reason that artifact was created, sent here or left here, may have had nothing to do with anything scientific or what we would consider logical. It may have had as much as anything to do with the passions, the dreams of the creators.”

Dreams which may take us to the stars.

All alone in the dark of night?

Perhaps:

Earth could be unique among 700 quintillion planets in the Universe, study finds

So much of humanity’s astronomical research is based around the notion of finding something like us out there – whether that’s looking for environments that could sustain life, ranking planets in terms of their potential habitability, or comparing distant worlds to our own.

But what if – statistically speaking – the odds are stacked against us finding another planet even remotely like Earth? That’s the thinking behind a new study by an international team of researchers, which has taken what we know about the exoplanets that lie outside our Solar System and fed the data into a computer model.

Their resulting calculations, designed to simulate how galaxies and planets have formed over some 13.8 billion years, produces a “cosmic inventory” of terrestrial planets – and one in which Earth very much looks to be unique.

 

Perhaps not:

Jon nodded. “Thanks. So what’s the meeting about? What happened?”

“Dr. Jakobs tried to contact you this morning. After hearing her message, I bounced it up to Director Magurshak. They found something on Titan. An artifact.” Seth paused, looked down at his hands, “a nonhuman artifact.”

Jon sat there for a moment, trying to digest what Seth said. According to what pretty much everyone thought, it wasn’t possible. SETI, OSETI, META and BETA had pretty much settled that question for most scientists decades ago, and twenty years of settlement efforts throughout the solar system hadn’t changed anyone’s mind. Even with the Advanced Survey Array out at Titan Prime searching nearby systems for good settlement prospects, there had never been an indication that there was an intelligent, technologically advanced race anywhere within earshot. Seth knew Jon well, didn’t let the silence wait. He looked back up, eyes level and unblinking, “It isn’t a hoax. The artifact is definitely nonhuman, or at least non-contemporary human. Mr. Sidwell found it out near his base. Dr. Bradsen will have as much a report on it as is available, which isn’t much.”

“We are on a marble, floating in the middle of … nothing.”

Via BoingBoing, this completely delightful short video about the scale of our solar system:

That does a better job of getting the real sense of scale than just about anything else I’ve seen. Wonderful.

You never know …

One fourth.

Tomorrow I turn 57. Yeah, on the Fourth of July.

That might seem a little weird to someone who doesn’t have a birthday on the Fourth. Not to me. I’ve grown up with it.

But you know what seems weird to me?

That I’ve been alive for almost one-fourth of the entire time that the United States has existed. Run the numbers, and you’ll see.

It’s very odd to realize just how young our country is in some ways. And how much things have changed just in my lifetime.

I remember the early days of the Space Race. I remember the night Neil Armstrong and Buzz Aldrin walked on the Moon.

And I remember growing up with casual racism of the worst sort. When homophobia was so deeply ingrained and widespread that the word itself didn’t even really exist. I remember using words like n***** and f***** without a trace of embarrassment, because they were so common.

Things have changed somewhat. Not enough. But still, too much for some people. Because change can be scary. Threatening.

The length of my life will take you to the time of Sputnik. The length of another such will take you back before Kitty Hawk. And just one more will land you well before the Civil War.

Change can be hard. And the fight never ends. But have hope: progress can be made. Both for individuals and for countries. Perhaps, even, for the whole world.

“Uh, he’s already got one, you see.”

Happy 25th Anniversary to the Hubble Space Telescope, which has rightly been called one of the most important scientific tools in human history. It has brought the cosmos closer to us, just as it has helped to drive home an understanding of precisely how far away those twinkling lights in the sky actually are … and connected to that, just how old our universe is:

The depth of Hubble’s data, however, has touched or rewritten nearly every area of astrophysics. Ever since the discovery of the expanding universe in the 1920s, astronomers had struggled with the rate of expansion and what it means. The so-called Hubble constant, the universal rate of expansion, was much in doubt, with two factions arguing very different conclusions from the data. The Hubble constant is also inversely proportional to the age of the universe, another key holy grail of science. One of the primary goals of Hubble was to measure the Hubble constant accurately, using a variety of distance indicators, and by the turn of the 21st century, this helped define a relatively accurate Hubble constant of 72±8 and an age of the universe, which the more recent European Planck satellite has refined further to 13.8±0.04 billion years.

 

It’s an amazing piece of technology.

But I can’t help remembering that even as amazing as it is, a few years ago it was revealed that it was considered so … obsolete … that US spy agencies had just given NASA two other surplus Hubble-type instruments they no longer wanted to bother to store. As I noted at the time:

…we’ve just found out that what we thought was at the limits of our technology is so obsolete that it can be handed off as so much surplus junk. And the implication is that while NASA is currently without the means to launch and service something like Hubble, that there are plenty other agencies within our government which are not so inconvenienced.

 

Which brings me around to the title of this blog post. Monty Python fans may recognize it from this scene in the Holy Grail:

Which I just happened to watch this week, and snickered over, remembering the news item about the HST from 2012. Though of course, in this case I hope that the National Reconnaissance Office wasn’t *quite* so taunting of NASA …
