The Chinese space programme
Still catching up after Christmas, I’ve been reading an official report from China issued on 29 December, about their plans for space activities in the next five years. In a post in August 2010 called “What language will they speak on Mars?” the answer was “Chinese, on present showing”.
It harked back to a prediction by Wernher von Braun made in 1964.
Man may have landed on the surface of Mars by 1984. If not, he will surely have made a close approach for personal observation of the red planet. Likewise, manned ‘fly-bys’ to Venus will have been made.
Lunar landings will have long since passed from the fantastic achievement to routine occurrence. Astronauts will be shuttling back and forth on regular schedules from the earth to a small permanent base of operations on the moon.
Although unstated, von Braun’s reliance for the Mars flight was on a nuclear rocket called Orion, which was cancelled soon after he wrote his article. Since then the US space programme has faltered or veered about under a succession of Presidents with different priorities. The present lack of American transport to take people to the International Space Station ranks with the British navy’s current construction of aircraft carriers for which there’ll be no suitable aircraft.
By contrast the Chinese space engineers, although starting about half a century behind the USA and Russia and still only moderately funded, are now moving steadily ahead with a programme that has clear and mutually compatible objectives. The new plan includes developing a space laboratory and collecting samples from the Moon by 2016, and building a more powerful manned spaceship. No date is given for a manned landing on the Moon, but that is under study.
The Army coordinates the space programe. Although the report is careful to say, China always adheres to the use of outer space for peaceful purposes, and opposes weaponization or any arms race in outer space, there’s military significance in the BeiDou (“Compass”) navigation satellites. Western and Russian systems are downgraded to stop them guiding hostile missiles too precisely. But with ten BeiDou satellites already launched and focused on East Asia, the Chinese intend to have a 35-satellite global navigation system by 2020.
As for their first shot at Mars, the Chinese have been thwarted by the hoodoo on Russian missions to the Red Planet. Yinghuo-1 (“Shining Planet”) rode piggyback on the Russian Phobos-Grunt spacecraft launched from Baikonur on 8 November last. The pair failed to escape from Earth orbit and disintegrated into the Pacific Ocean on 15 January. There’s been word that the Russians would like to blame a US radar for spoiling their mission, but that’s far-fetched. And the name Yinghuo-1 surely implies that the Chinese will try again.

Climate Change: News and Comments
Full steam ahead for the real story of 20th Century warming
Although It seems a strange thing to celebrate, the Titanic Festival in Belfast, where the ship was built, will very soon mark the 100th anniversary of the liner’s foundering on 15 April 1912 after hitting a south-wandering iceberg, with the loss of a multitude of passengers and crew.
Comparing the £100-million Titanic complex newly built in Belfast with the Guggenheim Museum in Bilbao, the travel writer Simon Calder has commented, “There is a great shipbuilding heritage, it is a divided city, but the Guggenheim is great on the outside but rubbish on the inside – unlike the Titanic building.”
What’s more, James Cameron’s movie “Titanic” has been remastered in 3D for the centenary.
Time then for me to dig out some slides that I’ve used off and on in lectures since 1999 as an illustration of Henrik Svensmark’s cosmic rays in action, controlling our climate. But first, just to show that I’m not being kooky, here’s a graph from a 2000 paper by E. N. Lawrence of the UK Meteorological Office. “The Titanic disaster – a meteorologist’s perspective” related iceberg abundance at low latitudes to a scarcity of sunspots.
by E.N. Lawrence
And Steven Goddard recalls a much older article, from the Chicago Tribune in 1923, that also linked icebergs with sunspots http://stevengoddard.wordpress.com/2011/07/28/1923-article-linked-icebergs-with-sunspots/
The notion that the Sun is dimmer when there are few sunspots goes right back to William Herschel at the beginning of the 19th Century. The trouble is that the variations in solar brightness, as measured by satellites, are too small to explain the strong influence of the Sun on climate as recorded over thousands of years, and continuing into the 21st Century. That’s where Svensmark’s discovery of 16 years ago comes in, with the amplifier. Cosmic rays coming from the Galaxy are more intense when there are fewer sunspots and they increase the global cloud cover, so cooling the world.
Some preliminary comments before showing my own slides about cosmic rays and the fate of Titanic. Of course the disaster also involved several elements of shameful seamanship, but the fact remains that large icebergs abounded much further south than usual in the spring of 1912. Secondly, I prepared the slides so long ago that I can’t recall the data sources. If challenged, I expect I could dig them out, and I do remember that the picture is from the Illustrated London News.
There was no direct recording of cosmic ray variations in those days. Indeed. Victor Hess was busy discovering them at that very time. So we have to make do with the geomagnetic activity index (called aa in the second slide) as an inverse indicator of cosmic ray influx, and with the counts of beryllium-10 and carbon-14, which are made by cosmic rays. Otherwise the slides should speak for themselves.

The theme music of Cameron’s film “Titanic” is entitled “Full Steam Ahead”. Although the ship came to an abrupt halt, the same has not happened to Svensmark’s theory. As plenty of other posts on this blog will show you, its bow wave keeps sweeping aside the attempts to falsify it. And fresh energy builds up more and more speed as all the pieces of the hypothesis fall into place, from quantum chemistry to the shape of the Milky Way Galaxy.
It’s a truly titanic idea, threatening disaster for the multitude who ignore the natural drivers of climate change, and shame for the misguided folk on the bridge who peer at computer screens instead of looking out of the window.
