I saw an interesting Update on LinkedIn today. Yesterday, 20 July, was the anniversary of
the Apollo 11 moon-landing, the first in history. The poster suggested that the apparent lack
of ambition in terms of space flight nowadays might be countered by the
creation of a global space agency. There
were a couple of Likes and a couple of Comments, making the probably valid point
that we as a species should be spending more money on cleaning up the mess we
have made of our own planet before worrying about going anywhere else.
In the first place, I confess to missing the anniversary
completely. I can remember vividly as a
16 year old kid sitting in the Red Lion pub watching the Saturn rocket blast
off from Cape Canaveral. I remember
sitting up all night watching the grainy black and white images broadcast to
the world’s TV screens of the landing, and the “giant leap” moment when Armstrong
stepped off the ladder to seal his place in history. I can remember thinking that I would love to
go there myself someday….. I followed
the entire mission closely, and that of Apollo 12. Like the rest of the world, I prayed for the
safe return on the ill-fated Apollo 13 mission (so well captured in Ron
Howard’s movie). I marvelled at the
entire Shuttle program, and wept for the fatalities aboard the doomed
Challenger and Columbia flights.
And I feel saddened by the apparent lack of imagination and
intent displayed these days by once pioneering NASA.
I’ve blogged about this before (see the post “Out of this World” from October 2010 if you’re interested).
In the nearly four years since I posted it, not a lot has changed.
NASA concentrates on unmanned missions to the outer planets
and asteroids and trying to land on comets, and supplying crews to the ISS, and
planning, seemingly half-heartedly, for a manned mission to Mars at some
ill-defined point in the future. The
Russians continue to provide the only means of getting people to and from the
ISS in the absence of a replacement for the Shuttle. They sometimes suggest they’re planning to go
the Moon or to Mars, but it always comes across as even more half-hearted than
NASA. China and India continue to creep
slowly forward with their own plans, mainly again in the realm of satellite
technology, while both say they hope to go the Moon and/or Mars and establish
viable colonies in 50 years or so. The
EU – satellites, and the odd national spending time in the ISS, mainly it seems
for publicity.
And that’s about it.
To all intents and purposes, mankind seems indeed to have lost its mojo,
at least as far space travel is concerned.
It depresses me now more than it did four years ago.
Now I know the arguments.
I recognise that sending anything into space is hideously
expensive. I know that the parlous state
of the world’s overall economy means governments must think very carefully
about the most cost effective and beneficial ways of spending what money they
have – I have to do that every day as an individual.
I know that things like climate change, and healthcare, and
food provision, and waste disposal, and alternative energies, and a hundred and
one other concerns require increasing amounts of funding too. Governments everywhere face increasingly
complex demands for their tax revenues.
I recognise too the arguments about going out into the
universe and trashing other planets not being the best advertisement for human
civilization (whatever that is – I’ve yet to see a decent definition), and
essentially sympathise with them.
But, I’m sorry, I cannot bring myself to agree with them.
Man has always been an explorer. I’m sure when Columbus set off to find a
passage to India, a lot of Portuguese citizens complained about the Royal
family wasting so much money financing this Spanish adventurer. But off he went, got lost and discovered (or
at least re-discovered) the Americas, and the rest, as they say, is
history. Britain probably faced similar
complaints when it started its Empire building but got around the problem by
employing the Armed forces and convict labour.
This is what humans do.
It is part of the never ending search for knowledge. That is what has dragged us, often kicking
and screaming, from the plains of pre-historic Africa, to every corner of this
old world we inhabit. That search for
knowledge has also brought us from the first flint and bone tools to modern
weapons systems (perhaps not the best advertisement for progress, but valid
nonetheless). It’s brought us from cave
paintings in blood and sand and water to today’s 3D and wide screen tv’s and
cinemas. From the wheel to the Large
Hadron Collider at CERN in Switzerland.
The Wright brothers first took the air in a flimsy wood and
fabric glider in 1903. That entire first
flight, from take-off to landing, could have taken place INSIDE the body of a
stripped down Boeing 747 freighter – a plane that itself first flew not much
more than 60 years after the Wright’s maiden flight. That’s well within a single lifetime. Two years after the 747 took to the air,
Apollo 11 landed. That is phenomenal
progress.
Look at old pictures of the Mission Control centres in
Houston and the Cape. Row upon row of
desks, each with its own computer screen showing a little bit of information,
each to be interpreted by its operator, often armed with a pen and paper and
slide rule. There is now more computing power
in the average smartphone than ran the Apollo program. We’ve gone that far, in terms of computer
power, in less than 50 years. The
internet has grown from a handful of users, all scientists in a more or less
closed environment, to ubiquity in half that time.
The oldest airline is KLM, founded in 1920. Before it celebrates its centenary, Virgin
Galactic, an off-shoot of Virgin Airlines (itself only 30 years old), will
carry its first paying passengers into space for an hour’s joyride at a cost of
a quarter of a million bucks or so. It
has a waiting list of passengers already.
This progress has all been great, and in many ways has given
us all a better life. But it’s not
perfect – nothing ever is.
Not everybody has access to it all for a start. Huge swathes of the population still live in
poverty and have no job or home. No
amount of iPhone computing power is going to help them. As manufacturing has gone up – and despite factory
closures world-wide, businesses continue to start up and flourish - the demand for raw materials shows no sign of
abating. This leads to increased output
of greenhouse gases. This in turn leads
to global warming, as far as many scientists are concerned (although many more
would strenuously dispute that). And
what no-one denies, the supply of those raw materials decreases, and once they’re
gone there is nothing to replace them with.
The population too continues to grow. There are in excess of 7billion people on
this Earth now. It’s expected to reach
10billion sometime around July 2060 (source: the fascinating Worldometers
website at
http://www.worldometers.info/world-population/). That’s
a lot of people to feed, when the land mass itself isn’t changing size to keep
pace with population growth and the amount of arable land is actually
decreasing as cities and, worse, desert areas get bigger all the time. So as well as shortages of raw materials like
oil and various ores, we are facing, soon, food shortages too. Expect poverty levels to go up then.
Scientists are working on of these issues of course, but
they faces challenges as big – perhaps bigger – than any that we have faced
before. New energy sources are
needed. Nuclear is good but accidents
like Three Mile Island and Chernobyl and Fukushima have turned many people, in
particular environmentalists and (crucially) vote chasing politicians against
it. Wind power increases in popularity
but is still relatively inefficient and those same environmentalists tend to
object to the proliferation of wind turbines that spoil sometimes beautiful
landscapes. It takes an awful lot of
turbines to match the energy output of even the smallest power station. Solar power is good and increasingly
efficient, but expensive to install and still reliant on the weather: fine in
the southern Mediterranean, the Gulf states and similar areas of high sunshine,
less acceptable in say northern Europe, or the extreme southern parts of South
America and New Zealand, where the climate is cloudier and wetter.
In food terms, scientists in the Netherlands have grown meat
(or something like it) by a sort of cloning process, building a burger cell by
cell. It took a couple of months and cost
millions. Other protein sources such as
insects (fried cockroach anybody?) are being seriously discussed as foods of
the future.
All of which, in my humble opinion, as a layman with no
vested interests (beyond living), suggests that in not too many years’ time,
this old Earth will become incapable of sustaining anything remotely like even
a modest way of life. Mankind needs,
desperately, more space. More raw
materials. More energy sources. More food.
For this reason alone, it seems to me, there is an
imperative to move out into realms beyond this Earth. This is what people have been doing since
time immemorial, moving on to find themselves more space and food and, yes,
wealth. But we have almost exhausted
everything there is to find and exploit here.
So it seems to me we need to rediscover this spirit of
exploration, of going somewhere new and dangerous and exciting. We all know it will cost huge amounts in
money and, perhaps, lives – but relatively speaking that has always been the
case, and it hasn’t stopped us yet. It
should not stop us now.
It seems, however, that NASA and its worldwide partners and
competitors are lacking that spirit, at least individually. Perhaps a Global Space Agency is the way
forward, a pooling of minds and ideas.
It works at CERN, but that seems to be an exception. The US, Russia, China, India and the EU seem incapable
of sitting down in a room and coming up with any kind of consensus. They have failed to do so in the face of the
on-going Palestinian and Syrian
genocides. They are failing to do so in
the wake of the murderous downing of MH17 over Ukraine. There are always, but always, competing
priorities and cost concerns and vested interests. Perhaps there always will be, but I hope for
the sake of us all, and our grandchildren, that I’m wrong.
A final analogy. Put
yourself in the place of Mr and Mrs Ugggg, the first humans on the plains of
Africa when food starts running low in their little valley. Mr.Ugggg is insisting they should move on and
find somewhere else where there is more to eat.
Mrs.Ugggg wants to stay where she is – she’s just cleaned the cave
(again), she has skins to cure and the kids are settled and there’s still at
least one wild pig to eat….. But
Mr.Ugggg is insistent, so move on they do.
And this turns out to be a good thing, for their ancestors proceed to populate the
entire planet over the next several millennia.
Sadly, it seems to me we are all turning into Mrs.Ugggg, at
least as far space exploration is concerned.
