China To Launch Second Manned Mission 155

Posted by Zonk from the weee-look-at-the-view! dept.
the_central_kingdom wrote to mention a Xinhuanet article discussing a second upcoming Chinese spacecraft launch in October. From the article: "Although Sun did not provide details about the new mission, space officials earlier said China has been preparing for the second manned venture into outer space since the first mission, piloted by Yang Liwei, almost two years ago. Sun Laiyan, chief of the China National Space Administration, earlier told China Daily that Shenzhou VI will carry two men into orbit for five or six days. "

          It might be more interested in research than impressing other countries. But what it's truly interested in is drumming up good publicity for the current administration (ex: Mars manned missions). People dying is very bad publicity that manned missions simply can't counteract. Therefore manned missions is dropped to a low, with unmanned missions emphasized.

      Of course it's all economics. If it were cheaper to send a manned module up to put a satellite in orbit, NASA would be doing it that way. However, it is far, far cheaper to send up just the satellite, rather than the satellite plus the astronauts plus their life support equipment and supplies, plus the re-entry vehicle. Oh, and let's not forget all the safety constraints that a manned launch requires that an unmanned one doesn't.

        GDP per capita is a usefull comparison when you are trying to measure quality of life but not when you try to measure scientific progress. Granted at current levels Chines might not be able to afford SUVs in every driveway but they can afford to spend on centrally funded programs. As you said there are 4 times many Chinese thus if you want to spend 100 million on a mission every Chines just needs to afford 10 cents but every american needs to afford 40 cents. Larger population is generally an advantage given similar levels of education. Moreover while the Chinese GDP might be 7 trillion on paper everyone knows the Chinese currency is artificially lower by 20% so in real terms it is already larger than the US GDP. Things like space exploration are a kind of national luxury and they are affordable based on the whole GDP and not GDP percapita. After all their is only 1 NASA and 1 CNSA. Even not considering the exchange rates your argument about US remaining ahead falls apart as China is growing faster 9% compared to 4% . According to WB and IMF projections Chinese GDP will overtake US GDP by 2015 and by 2050 GDP per capita too will overtake US GDP. This is assuming no major wars. Given that the US is currently stuck in an expensive war which may drag down growth these points may be reached earlier. Its already becoming obvious that the US is no longer as attractive as before. Just look at the number of foreign students who stay on in the US. Earlier most foreign students would never go back to their countries as the US had the leading industry and the best opportunities but nowadays more and more Chinese and Korean students go back as opportunities at home are equal or better than in the US. So their really is no place for complacency

Growing a nations GDP by 1 trillion is a few years let alone more than 4 trillion is just impossible. China has _at least_ 1 billion people. Divide their GDP by their population and you get about $7,262 per person. The USA has about 300 million people. Divide our GDP per person and you get about $39,166.66 per person. A _huge_ difference, more than five time the amount _per person_!

        A few notes:

        1.) Your figures are probably from the CIA World Factbook, which reports purchasing power parity GDP. Comparing nominal GDP makes your argument stronger, as the PPP GDP for China is substantially smaller. One source [chinadaily.com.cn] has the figure for 2004 at $1.65 trillion US. However, the PPP number is useful in that it's probably a better comparison with US output, I believe due to the rather extraordinary circumstances with the yuan dollar peg kept artificially low. Still, that said...

        2.) China's GDP growth is pretty spectacular, and has been so for the past several years (check the World Bank's World Development Indicators database). 9.5% reported growth in 2004 is probably unsustainable, but China had GDP growth of 7-9% for 1999-2003 (according to the WB). The US, by comparison, had growth of 1-4% between 1999 and 2003 (admittedly including a recession).

        3.) Your argument about per-capita GDP works against you. Few believe that the average Chinese person will be as wealthy as the average "first world" person any time soon. The point is that China, as a political and economic powerhouse, will likely become even more huge in the near future. The large population bolsters this goal, as it provides low-cost labor and a quick opportunity for growth. One only needs to raise per-capita productivity a small amount to see huge gains in overall GDP for the country as a whole.

        4.) Let's take your original figures of $7.26 trillion versus $11.75 trillion. Assuming China can keep up a 7% growth and the US has about 3% growth, China will reach the $11.75 trillion mark within 8 years. At those rates of growth, China will exceed the US within 13 years. Even if these figures are quite off, China is still likely to have a much larger economic role than it does now in the coming decades.

        • PPP GDP for China is substantially smaller

          That should read, "nominal GDP for China is substantially smaller".

        • Divide their GDP by their population and you get about $7,262 per person. The USA has about 300 million people. Divide our GDP per person and you get about $39,166.66 per person.

          Interesting train of thought. Since the U.S. has about the greatest class differences outside Swaziland (I've read that the top 1% own as much as the bottom 90% in the U.S.), I wonder how much closer average income would be if someone subtracted that richest top 1% from each country. Anybody know the figures?

      Unmanned missions are a necessity with the present-day American mindset. Haven't you noticed that every time one of our astronauts dies, our space program grinds to a halt for years?

      We (the USA) have lost the pioneer spirit... If we're really going to stay ahead of the Chinese (and Indians, and Russians, and whoever else) the USA as a country has to understand that tregedies will happen, and some brave souls will die in the name of progress, and they knew the risks of that happening when they signed on for the job.

      It's always easier to follow than to lead. So far they're not doing anything new just copying what has already been done.

      They may also be able to catch up faster by taking fewer precautions. If our current space program had the same level of redundancy as our Apollo missions we'd probably be spending a lot less, running many more missions and possibly losing more people.

      A lot harder. You can reach orbit at about 25,000 km/hr. Escape velocity, which is necessary to reach the moon, is 40,000 km/hr.

      Because energy is proportional to the square of velocity, that's about 2.5 times as much energy.

      Then, when you re-enter the earth's atmosphere, you have 2.5 times as much energy to burn. Simple ballistic re-entry techniques won't work for this; you need aerodynamic negative lift to sweep a big arc while you're re-entering.
