China to Launch Solar Telescope 33
Dirak writes "China plans to launch the world's largest and most advanced space solar telescope (SST) into 735-kilometre-high earth synchronous orbit in 2008. Japan and the United States are also jointly developing an SST, coded as SOLAR-B, now scheduled for launch in the September of 2005. But with a diameter of 0.5 metre, SOLAR-B has half capability in optical resolution than that of the Chinese-made solar telescope."

When the Chinese can fly their own SR-71, we'll talk again.
Or scramjet.
And one day, they might actually have an aircraft carrier.
On the other hand, research from multiple countries in space exploration is good to foster views from different angles and with different motives (the chinese solar telescope will certainly not be the "baby" of the US Air Force).
Anyway, this post is full of doo, so I'll go back to sipping on my brew.
Coffee--brew. Jees.

While it is true that the US is is still the leader in technological developments, there are some trends that make it a distinct possibility that this will not be the case for much longer.
The dual trends of cutting school budgets and funding only scientific projects that are 'christian-approved", can quickly destroy the academic infrastructure that got us the lead in the first place. Americans are NOT genetically more intelligent than other people.

Don't get me wrong, going to Mars would be a great achievement and I think it should get support, but it is highly unlikely that it will occur anytime in the next 20-25 years. We shouldn't slack off in all unmanned science in space until that point.

Well NASA had that problem even before Bush. Just look at what happened with the X-33.

Second, Bush has leaned on congress and got a funding increase for the Mars push when the Senate approved the NASA budget.
Thirdly, the Moon/Mars push will primarily take budget from the shuttle and ISS once those are done. Some additional funds will be diverted from other projects but science project stuff like this will continue.
Don't forget the science that will be obtained from manned Moon and Mars missions. Before you flame me about how rob

When the Chinese are able to put their solar observatory at a libration (a/k/a "LaGrange") point like where SOHO is, then we can start asking this question. Until then, it sounds like they'll have a solar observatory that won't be able to look at the sun for parts of the year.

Forces on China include:
- Very rapid urbanization from population migration;
- Rapid economic growth
- Poor banking & financials regulations & enforcement
- Poor government and corporate transparency (enables wise investments), leads to poor use of capital;
- poor court systems - rapid growth in new commercial lawsuits, no infrastructure;
- vast environmental damage that won't really hit for 20 years but when it does it will be very, very bad;
- poor roads and rails infrastructure (political not market driven locations/sizes);
- little democratic traditions on local levels (feeding county/state/federal governmental structures' elected officials)
- history of totalitarian regimes - "never underestimate the ability of a country to act the same as it has in the past";
- strong pressure to limit political change ("those that disallow little peaceful revolutions invite big violent revolutions")
- unstable authoritarian bordering regimes (North Korea and others);
- educational systems based on rote learning instead of independent questioning;
- increasing instability in currency markets from rapid growth & partial convertability of Won to Euro/Dollar/etc.
- Internet technolgies uncapping info wall keeping electorate in dark about bad government actions without allowing corresponding social networks of interested reformers to push for change legitimately
Just a couple of items on China's plate right now. Of course, a space program gains prestige. But it also takes the minds of your citizens off the fact that their lives are rapidly changing, and too-rapid change coupled with social dislocation breeds for backlash (examples abound).And you wondered about the role of China in the world economy. Their space program is a (possibly helpful) diversion and may be worth the money even if the only thing it does is inspire the kids of 1.x billion people to think about tech change in the engineering terms of 'gradually building on the shoulders of giants' instead of 'fearsome magic wrought at our expense'.
And all I know is what I read in the Economist [economist.com]. Just think what the World Bank's experts know. Let's hope they know enough to help.

Nitpicking - this is true of all orbits. A synchronous orbit is one where the orbital period matches the rotational period of the central body.
You calculated is correctly, mind you, and seem to have a clear understanding of the issue. Except for that one little part of your explanation.

If you want an unobstructed view of the sun you need a much higher orbit, like the moon which is eclipsed at most twice a year IIRC. Or you need to leave earth orbit altogether, like soho which is at the earth-sun L1 point.

Dunno if an 800 km orbit can counter the earth's revolution around the sun though (and am too lazy to calculate that right now).

This could be somewhat usefull for regular communication with the satellite from China, but I don't see why it would be worth the expense of a polar orbit for that.
