To the moon!

Autumn is killing me (metaphorically) – with shorter days and the lack of sunlight I’m continually tired, an at the moment I’m glad when I finish paid work in time, so I would ask the people who asked for held for a little more patience (I know I make these excuses quite often, but there you go).

So while I can’t provide an update on the module I can at least give you a small update on what’s happening in space, because these last few days have been a good time for space exploration.

At Oktober 21. a soyuz capsule returned to earth from the ISS; part of the crew was Sheikh Muszaphar Shukor, the first astronaut from Malaysia. I was actually a little annoyed that his religion was so much a matter of public display – but then it’s probably just fair, Christians did it before with bible readings from orbit, and one has to commend Malaysias religious authorities that they managed to reconcile not religion and rationalism, which I think is impossible, but at least religion and pragmatism in such matters as prayer times and such. But as a life long Saganite I’m much more pleased with international cooperation.

A new crew member and new equipment is on it’s way to the International Space Station with STS-120 and the Orbiter Discovery. Shuttle Commander Pamela Melroy and her Crew deliver a new module – Node 2 a.k.a “Harmony” – to the station which will mainly serve as a connection point for other modules, including the european Columbus. Speaking as a european I can hardly wait. And it’s time that a bit more science happens at the ISS.

The International Space Station has been pretty much a failure so far, and I think this can be largely attributed to the fact that construction lags so far behind the planned schedule – Russia had a delay in manufacturing station components and there was another shuttle accident and the thing is by now much more expensive than planned (I nearly wrote “as expected”) and generally things haven’t been going to well. Phil Plait of Bad Astronomy fame hinted somewhat subtle (and a number of commenters brought the point home quite bluntly) that the station should be dropped althogether (if this were possible). I usually agree with what Dr. Plait says, not so much because he’s an expert but more because he is an expert who will happily eat his own words if it turns out he was wrong. But I still think the station should be finished, because if we – and it’s “we”, this is an international project – can’t even finish a project more or less at the front door then how can we ever think about building more ambitious projects (like e.g. interplanetary spacecraft) ?

But maybe there should be a lesson learned for later projects. I’m all for international cooperation (that Sagan thing again), but if possible partners should contribute complementary, not interdependent parts, so that a mission can still be sucessful when one piece is delayed or even fails.

Of course some people try to do things on their own (especially since they were obviously shunned from working on the ISS, I hadn’t been aware of that), which makes for the most exciting news – China has sent the Chang’e 1 probe to the moon, and that is only the first step in an rather ambitious space programm that is supposed to sent a man to the moon in the next 15 to 20 years. I guess by now a manned flight to the moon is not so much a matter of available technology and more a question if you are willing to spend the ressources (I’d venture that a moon base would be less expensive than the US war in Iraq…), which makes China the best candidate for a return to the moon – the Chinese seem to only ones willing to pull this off. Perhaps if we ask nicely they will sell us some tickets ;-)

And speaking of the moon, Japan Kaguya probe has now reached an orbit from which it can start scientific observation – it’s a pity I don’t speak japanese (or ’scientese’ for that matter), but I expect sooner or later some bits of data will trickle down to us english-speaking laypersons.

As I child I used to watch Space 1999 on television and being a child an sometimes unable to distinguish fiction from reality I was convinced that there would be a permant presence on the moon by the time I would grow up and I could buy a ticket to get there. Most annoyingly this hasn’t happened. But even if I can’t go there I hope somebody will.

    Al Gore and the Nisbet School of Communication

    Filed under: Science, Science Fiction — Tags: , — Eike @ October 14, 2007 2:31 pm

    The peace nobel price 2007 went to Al Gore (that’s this slideshow-guy) and the United Nations’ Intergovernmental Panel on Climate Change

    for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change“.

    Since climate change possibly leads to more conflict (e.g. over water reserves or arable land) and since there is no dedicated enviromental price that carries the same reputation as the peace nobel (propably because we still see enviromental problems as temporary) this seems a justified and good decision of the nobel committee.

    While (as far as I can tell) the decision for the IPCC goes uncontested some people try (again) to turn Al Gore into a controversial figure. A particularly annoying example is Matthew C. Nisbet who asks at his blog if Al Gore is contributing to a perceived (by Nisbet, that is) communication crisis. His argument is that, while more and more US Citizens of a Democratic persuasion think of anthropocentric global warming as a problem Republicans usually don’t. That Republicans deny global warming is, according to Nisbet, all the fault of Al Gore.

    This is of course nonsense. Republicans dislike Al Gore for pretty much the same reasons that arsonists dislike the fire brigade – the latter defies the raison d’être of the former, and denying there is problem comes more naturally to them than changing their ways (I should point out that I’m aware that similar rifts in society exist in other countries, it’s actually Nisbet who makes an US-centric argument). I think Nisbet is actually trying to save his hobbyhorse, some sort of semantic Sleipnir that has lost at least six of his eight legs to the flak it drew from other bloggers (please excuse the strange metaphor, since the mythical horse Sleipnir is the bastard of a traitor it seemed somehow fitting).

    Matthew Nisbet clings to a theory called frelling frakking “framing” science – I’m not actually sure how his version of the theory relates to the linked Wikipedia entry, since the main assertion in his blog is that others are doing “it” wrong, and there is little advice on how to do things right. The only unambigous instruction I found was to claim that it’s really possible to reconcile science and religion (and that I do not believe; the only way to reconcile both is to pervert either your science or your religion). The basic idea seems to be that scientists should phrase their work in more folkloristic terms so that it becomes more accessible to laypersons, and that if somewhere somehow somebody fails to understand a theory scienticts should be severly reprimaneded for their failure to educate each and every simpleton.

    Better blogs than mine have commented on why this particular post of Nisbet was so stupid; I like to add the reason why I am personally against framing (at least where it exceeds a reasonable extent of simplifying matters for the laypersons sake). The reason is that I am a science fiction fan, and as such the idea behind “framing” sounds uncanningly familiar.

    In 1956 James Gunn published a story called “Witches must burn”. The protagonist of that story is a scientist, a psychologist who tries to flee the US after a superstitious mob has torched down the universities and killed his colleagues. On the run he uses every means at his disposal – his knowledge as a scientist and an experimental device that allows him to pick up brainwaves from others and, by careful interpretation, to vaguely anticipate their actions. He nearly made it out of the country when he meets an underground cult of Nisbets former scientists who disguise as witches and wizards. At first he does not believe in what they tell him, but little by little they manage to convince him that the universities deserved to burn, and those friends and colleagues deserverd to die, because scientists had isolated themselves so far from the ordinary population that lynching them became the understandable and in fact only possible reaction. The only way to counteract that would be, as Gunn phrases it in the story, for the scientist to become “one of the ordinary people again” and to engage in a way of science that is not offensive to the masses.

    That is was Matthew Nisbet has to offer – a third rate idea from a second rate story published fifty years ago in a pulp magazine. And equipped with that he contends he could do a better job to educate people about science than actual educators and scientists. How does he dare?

    As for Al Gore, he did a great job communicating some of the science behind climate change (even if some of the points from “An Inconvenient Truth” may be outdated by now. Such is the nature of science). I hope he doesn’t run for US president – while he has made clear that for him it’s the USA first (and why not? He is, after all, US-American), as long as he remains the public face of the cause instead of a combatant in the trenches of US politics we others can feel that he not only speaks to us but, to some extent, for us. And since (speaking for Europe) we are a lot less educated than american liberals courteously claim we sure can use a great spokesperson like him.

      Science breakfast

      Filed under: Science, Space, self referential — Tags: , , — Eike @ October 2, 2007 12:06 am

      A couple of days ago I visited a friend to see her and my – what would be the secular equivalent to a godson? My “Darwin-Son”? or “Dawkins-Son”? – well, to see her and her son (of whom I’m obivously quite fond, he’s two and a half and a very bright and lovable child). After some hours of playing ‘Make the Funny Noises’ and ‘Help me Catch the Red Balloon” the child was laid to sleep and we perused my friends library of science fiction series on DVD. I finally fell asleep to an episode of Regenesis (which is acutally quite good, only you shouldn’t try to watch all of it at once).

      The next morning my friend invited her new neighbour for breakfast, which was even more fun than I’d initially thought, because said neighbour turned out to be an astrophysicist from Brazil – she does work on black holes and currently stays in Potsdam for some fellowship thing or something. So we talked about black holes during breakfast (actually I asked some naive or maybe genuinly stupid questions and got some clever answers, but that still counts as talking, right?) before she anncouned that she really wasn’t working on black holes at all – instead she said “I’m working on something really weird”.

      That really cracked me up, because a star collapsing into a singularity is already pretty high on the list of weird things and it was funny that she could easily top that (is it too late for me to become an astrophysicist? The weirdest thing I see in my job is the CSS rendering of IE 6, and that’s rather more annoying than interesting).

      The “really weird” thing is Gravastar Theory. I tried to read up a little on the theory – I read the original paper by Mazur and Mottola and naturally I didn’t understand a word (at least none with more than three letters), so I read another paper I’d found on the internet by two guys names Visser and Wiltshire, which (I think) discussed the merits and faults of the theory and which I didn’t really understand either, so I resorted to the Wikipedia entry which I mostly did understand but which is not particularly exhaustive and obviously lacking even by Wikipedias standards.

      It may be weird, but it’ still interesting (and frankly so was my lecturer) . I should try and get another invitaton for breakfast.

        Dawn of the pronounced dead

        Filed under: Space — Tags: , — Eike @ September 28, 2007 12:41 am

        Okay, so this is the worst pun ever, but the good news is that as of yesterday NASAs Dawn Mission is on it’s way. Dawn is a mission to the asteroid belt and more specifically to Vesta and Ceres, two really, really huge rocks in space ( 500 km / 1000 km across) that feature in many science fiction novels as the most likely place for human habitats in the asteroid belt. Oh, and I guess they are of some scientific interest, too. Dawn had been effectivly canceled, was reinstated, then delayed – NASA has a problem with its science budget (I don’t follow american fiscal politics that closely but it would seem that the overall budget woes are due to governmental pressure while the unwise distribution of the remaining funds is a self inflicted problem, but what do I know) – so it’s some relief that things finally got going.

        So on the following pages you will find the really interesting stuff about the dawn mission:

        My heart really belongs to manned space exploration, but I have to admit that at the moment unmanned probes provide better bang for the buck. And I’m really looking forward to learn more about the asteroid belt and Ceres and Vesta.
