Overview is a stunning short film from the Planetary Collective, celebrating the fortieth anniversary of the famous “Blue Marble” photograph (taken by Apollo 17, see above) by talking with astronauts about the ‘overview effect’ – the change in perspective many of them experience when they get to do something that all the thousands of years of humans before the 1960s could never do: see the world from space. I’ve been a space geek since I was a very young boy, happy with a NASA costume and toy helmet, box for a ‘spaceship’ and imagination, and I’ve heard a number of astronauts and cosmonauts talk about this experience, about how viewing the world from above the clouds changes their perspective forever on how astonishing our world is, how remarkably beautiful yet fragile, how everything and everyone is interconnected… The imagery is beautiful…
With the shuttle programme – and NASA’s ability, for the moment, to send manned missions into space – now grounded and the surviving spacecraft being sent to various museums around America today there was a very special moment as a modified 747 carried a very special shuttle flying low over New York City for everyone to watch. The spacecraft was the Enterprise. The ending of the shuttle programme is much like the ending of Concorde for many of us – when we were kids they were the future, now they are history and that would be fine, it would be natural, if they were retired to make way for the next generation of craft to replace them, but they’re not. We’ve stepped backwards, it feels, become smaller. But for a final hurrah this was a remarkable one, the Enterprise, her very name resonates for many of us, flying over New York, captured here with Lady Liberty and the Empire State in the frame by Bill Ingalls:
What a remarkable shot, a couple of the great world landmarks with a piece of flying space exploration history. Enterprise was named after NASA called for a public vote to name the first spaceship; the geek community, of course, got together and made sure to vote en masse that she would be called the Enterprise, because she was the first of a series that would boldly go… Enterprise herself never brushed against the hard vacuum of space though, she started her career at NASA riding piggyback just like she was today – she was designed to test aerodynamics, a bit of a new area for spacecraft design at the time because most were odd shaped objects on the end of a rocket but the shuttle, she was meant to fly back down from orbit through the atmosphere like a conventional plane, hence the tests. As a boy I followed the emerging shuttle programme and remember well watching news reports of the Enterprise’s flights paving the way for the first full shuttle launch.
As a wee boy raised on repeats of the classic Star Trek it made me happy to see a real spacecraft being named Enterprise and, Americans being rather good at marking big occasions, when she was first revealed to the public Trek creator Gene Rodenberry and many of the original cast were there to wish her good skies, way back in 1976 (pic below and following borrowed from Space.com):
And here three and a half decades or so on is one of those illustrious crewmembers of the fictional USS Enterprise giving the Vulcan salute – live long and prosper – to his old friend, the shuttle Enterprise, as she heads for the Intrepid Sea, Air and Space Musuem in New York. Rather fitting she will be near the USS Intrepid, which any old Star Trek hand knows was the name of one of the other Constitution class starships in the original Trek, the same class of vessel as Jim Kirk’s Enterprise (Intrepid being crewed entirely by Vulcans, if my memory serves):
As I said, like with Concorde, it feels wrong to know that the shuttle are gone, that something that promised the exciting future of space exploration to a young boy is now a historical artefact in a museum and that we didn’t mothball them to make way for a new generation of faster, bigger, more efficient spacecraft. Still, one of these days there will be another Enterprise, I am sure. Larger, with a greater range, this Enterprise A, B or C ships will boldly go further… As Captain Jean-Luc Picard himself once noted when asked if they would ever build another Enterprise “plenty more letters in the alphabet”.
One day, another Enterprise, please, make it so…

Welcome to the Space Age
As Russians mark the 50th anniversary of planet Earth’s first satellite, Sputnik, taking flight IEEE Spectrum has an interview with the legendary grand old man of science fiction, Arthur C Clarke (link via Boing Boing). Clarke, of course, before becoming the hugely influential SF writer he would later become (we’re talking about a man who talked to presidents and kings as well as scientists and writers – also one of the few who was so respected he was friends with both astronauts and cosmonauts during the Cold War) wrote a speculative paper in the 1940s in which he imagined using geostationary space stations to act as relays for beaming radio signals across the entire globe, pretty much what we now have with a legion of satellites linking us up in ways we don’t even think about anymore – we use phones and watch TV largely without considering the world-changing technology which brings it to us so damned easily. All starting with a little silver ball called Sputnik going beepbeepbeepbeep around the world.
JPL and the ESA have announced that the Cassini probe has found a small, previously unknown moon around the giant world Saturn the sixtieth so far discovered around the ringed world. It may be a tiny lump of rock and ice but I love the fact that almost 50 years after Gagarin’s first space flight our own solar system is still surprising us. Makes me wonder what we will discover when we finally get further out (and why haven’t we pushed further, we let ourselves get so small after the Apollo missions…)
Elsewhere on the ESA site there’s a function to listen to the Huygens probe which descended into the large moon Titan from Cassini. The sound files aren’t especially interesting as such, in fact is is just a rather dull sequence of white noise, but the fact the first one is a recording of sounds heard on an alien world is. Sounds from a world no human has walked on, beamed across millions of miles to be heard for the first time in human history. Now that is impressive.
“My god, it’s full of stars…”
I looked at this astonishing image from the Hubble Space Telescope on the BBC’s site today of the red giant V838 Monocerotis, a star which exploded in 2002 and the first phrase that leapt to mind was astronaut Dave Bowman from Clarke and Kubrick’s 2001: a Space Odyssey – “my god, it’s full of stars.”
Dammit, why don’t we have those holidays in space I was promised as a kid yet?!?! I want to see these things for myself.
The BBC site had this astonishing photograph taken by the New Horizons space probe. This is Io, one of the moons of Jupiter, a world so large its collection of moons around it are like a miniature solar system (in fact it is reckoned if the gas giant Jupiter had been a bit bigger it would have reached the threshold to ignite the nuclear fires at its core and become a star, just as the sun did billions of years ago). Io is one of the Galilean satellites, one of the four larger moons first seen through an early telescope by one of my great heroes, Galileo, when he turned his new optical device on the king of planets. I’ve seen Jupiter through a large telescope at the University of Glasgow’s observatory myself, in enough resolution to see the coloured bands and even the mighty, centuries-long storm of the Great Red Spot; on either side of Jupiter’s glowing disc I saw two bright points shining like diamonds on black velvet and realised they were the moons Galileo had seen centuries before.
Io itself is a world which looks like an old-fashioned view of Hell, a surface covered in decaying yellows from sulphur, constantly reshaped by a continual series of volcanic eruptions as the enormous gravitational power of Jupiter twists the core of the little moon keeping it geologically active when most worlds that size would long have become inert, like our own moon. As well as tremendous gravitational tides the space between the moons and Jupiter is often filled with enormous amounts of high energy radiation – a beautiful but very inhospitable place; it increases my admiration for the skills of those who designed and operate these missions that these little probes can even function in such conditions. At the top of this image, almost on the terminator line separating dark from light, is an eruption from the volcano Tvashtar; this eruption is actually shooting out some 180 miles into space.
It reminds me of the triumphant Voyager missions years ago, when one woman noticed an anomaly on shots taken of Jupiter as the little probe left the system to continue its grand tour of our solar system (still the greatest voyage of discovery in human history to date). The data from those incredibly early computers was slow to process, even before taking into account the time taken to transmit that information to Earth over the vast distances. She noticed something strange and was at first unsure what she was seeing. Only slowly did she realise that one shot had, quite by accident, caught an eruption shooting right out into space from Io; a fluke shot and a chance find by that scientist to come across the first volcanic eruption humans had ever seen on another world. I’m just disappointed that all the promises of my childhood of holidays in space by the time the 2000s came around still hasn’t come to pass. When I hear idiots complaining about the money being spent on space exploration and how it could be better spent on problems on Earth (that bloody Davina McCall was the latest, showing her incredible ignorance) it infuriates me. As a percentage of budgets we spend very little on this actually; don’t demand cuts to exploration, cut the money on bloody massive weapons programmes, then we would have the budget for Earth bound problems like hunger and disease and to explore new worlds and learn more.
