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 …

George Mallory, the famous British mountain climber who may or may not have been the first to reach the summit of Mt Everest, supposedly responded when asked by a New York Times reporter “Why do you want to climb Mount Everest?” with “Because it’s there”. This, in the spirit of the day, was understood to mean that it was a challenge to be conquered, man triumphing over nature.
When I was young, I found this quote to be inspirational. Aspirational. It was, I thought, the perfect explanation for doing the seemingly impossible. For pushing boundaries. For climbing higher than anyone had ever climbed before. Perhaps all the way to the Moon. And maybe one day, to the stars.
Half a century later, I have learned the wisdom of having goals — or, perhaps more accurately, motivations — which make more sense over the long run. Because while “because it’s there” may lead to a temporary triumph, it is hardly enough over the long haul. If you want something to be more than just a moment of glory, captured forever in the record books but limited to only being in the record books, then you need something much more pragmatic.
So I was delighted to read this today, from Phil Plait’s visit to Elon Musk’s SpaceX factory and the question of why go to Mars:
Musk didn’t hesitate. “Humans need to be a multi-planet species,” he replied.
And pretty much at that moment my thinking reorganized itself. He didn’t need to explain his reasoning; I agree with that statement, and I’ve written about it many times. Exploration has its own varied rewards… and a single global catastrophe could wipe us out. Space travel is a means to mitigate that, and setting up colonies elsewhere is a good bet. As Konstantin Tsiolkovsky (the father of modern rocketry) said, “The Earth is the cradle of humanity, but one cannot live in the cradle forever.”
* * *
The overall atmosphere in the factory was one of working at a progressive company on an exciting project. Of course: They build rockets. But the feeling I couldn’t put my finger on before suddenly came into focus. The attitude of the people I saw wasn’t just a general pride, as strong as it was, on doing something cool. It was that they were doing something important. And again, not just important in some vague, general way, but critical and quite specific in its endgame: Making humans citizens of more than one world. A multi-planet species.
It’s easy to dismiss this statement, think of some snark as a way to minimize it and marginalize it as the thinking of a true believer. But—skeptic as I am—I’ve come to realize this is not minimal. It is not marginal. This is a real, tangible goal, one that is achievable. And SpaceX is making great strides toward achieving it.
That’s when I also realized that the initial question itself was ill-posed. It’s not why Elon Musk wants to get to Mars. It’s why he wants humanity to get there.
The Apollo Program was a phenomenal achievement. It was inspirational. Aspirational. But while it contributed many worthy technological advances, and led a whole generation of the best & brightest to go into science and engineering, there is a reason that there are still to this day only a dozen people who have ever walked on the Moon.
Musk’s goal is still visionary. And perhaps not pragmatic in the short term. But in the long term, species survival seems to be just about the most pragmatic goal humanity could have.

I mean, who doesn’t want to get out now and again, stretch your legs a bit?
Recently, NASA released some pretty spectacular footage captured by an astronaut wearing a GoPro camera while spacewalking around the International Space Station. In the videos, Earth slowly rotates below the space station while astronauts fiddle with cables, install antennae, and work on the robotic arm.

Via BoingBoing, fun video from NASA of the unboxing of a shipment of the first printed tools and tests parts from the ISS:
Perhaps it’s just the conservator in me, but I loved the documentation process, and how they’re going through everything carefully. No doubt that some or all of those items will eventually wind up at the Smithsonian Air & Space Museum.

A number of unrelated items which I thought I’d share …
* * *
Astronomers have announced what may be the most interesting exoplanet discovery yet made: five planets, all smaller than Earth, orbiting a very ancient star. And I do mean ancient: Its age is estimated to be more than 11 billion years old, far older than the Sun. These are old, old planets!
* * *
Perhaps you see the problem. If planets like Earth formed 11 billion years ago, and happened to form at the right distance for more clement conditions on the surface, life could have arisen long enough ago and started building spaceships long before the Earth even formed! They’d have planted their flags on every Earth-sized habitable planet in the Milky Way by now.
Where are they?
Oh! Oh! I know! Pick me!!

Thanks to all who helped spread the word about the 3rd anniversary promotion! It was a modest success, with a little shy of 200 books downloaded world-wide, including through the following Amazon portals:
- Netherlands (for the first time!)

Via BoingBoing, turn your iPhone into a thermal imaging camera in just seconds:
Yeah, I mentioned using this kind of imaging tech in the current novel some time back.
* * *
Speaking of tech predictions, this is the first step in the sort of thing I envisioned for the cyberware of Communion of Dreams:
* * *
I mentioned earlier that evidently the Wikipedia elves are trying to decide whether to nuke my entry there. It seems that they’re still debating it. As I noted on the BBTI Facebook page a few days ago, in response to comment by a friend that it seems weird that BBTI is little more than a footnote in that entry:
It’s a fair point. I certainly am known much better around the world for being the driving force behind BBTI than I am for a fun little art stunt which was intended to happen and then fade from memory. I know that BBTI has had a much bigger and more lasting impact in the real world.
So, whether or not an entry about me should exist at all, if one does exist, shouldn’t it be more about my part in BBTI rather than as a “internet performance artist”? Hell, even my work as a book & document conservator has had a much larger real impact than ‘Paint the Moon’ did.
Just a thought, if anyone wants to do some editing …
* * *
This doesn’t have anything to do with any of the books or anything I’ve predicted (that I can remember), but it is a pretty cool bit of astronomy:
Astronomers at the Leiden Observatory, The Netherlands, and the University of Rochester, USA, have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier than the ring system of Saturn. The ring system – the first of its kind to be found outside our solar system – was discovered in 2012 by a team led by Rochester’s Eric Mamajek.
* * *
And here’s a useful video for anyone out there who may need to remove some rust from old equipment:
I knew that this could be done with electrolysis, but I didn’t realize that it was actually quite so simple. I am definitely going to set up to do this on a number of old tools and suchlike.

A nice bit of space exploration history:

And I think I will leave it at that for now.

I should have some interesting news to share in a couple of days. But for now, I thought I would share this amazing post from Phil Plait at Bad Astronomy:
Yesterday, I posted an amazing Hubble Space Telescope picture. I don’t think it’s too soon to post another shot from Hubble… and I think you’ll agree when you see it, especially after you get an understanding of what you’re seeing.
First, the eye candy: The magnificent Andromeda Galaxy, as seen by Hubble.
And as Plait notes, that’s the low-resolution image.
Go enjoy the article, and marvel at the images he has/links to. Seriously — it is worth your while, if you’re any kind of a space-geek at all.

A mix of little things, playing catch-up for the last couple of weeks …
Why catch-up? Well, this might explain why I took a break for a while there.
And we’re off …

First thing, thanks to all who downloaded Communion of Dreams over the weekend, or helped to spread the word about it. There were a total of 693 downloads worldwide — and that includes various European portals, as well as Canada, India, and Japan! Pretty cool.
For those who have gotten the book, once you have a chance to read it please take a few moments to review it on Amazon or elsewhere – it really does help, and as I am finishing up writing St Cybi’s Well the feedback is most welcome.

A long, but quite good, read about the value of the ISS: 5,200 Days in Space

And a fun bit of perspective from xkcd about getting there:

Petre Ifan is a haunting burial stack that stands in a verdant Welsh field as one of the most complete and dramatic stone dolmens still found anywhere on the planet.

Go see the full size image and explanation of the science. Worth it.

An excellent read by an old and dear friend: There’s an App for That: Cancer in the Modern Age
* * *
And another excellent read, all in all. But this paragraph is so painfully true:
“Writing is a strange and solitary activity. There are dispiriting times when you start working on the first few pages of a novel. Every day, you have the feeling you are on the wrong track. This creates a strong urge to go back and follow a different path. It is important not to give in to this urge, but to keep going. It is a little like driving a car at night, in winter, on ice, with zero visibility. You have no choice, you cannot go into reverse, you must keep going forward while telling yourself that all will be well when the road becomes more stable and the fog lifts.”
