Japan Considering Moon Base, Shuttle Projects
ScentCone writes "A brief article at Newsday mentions a Monday report that JAXA, Japan's counterpart to NASA, is looking at robotic probes on the moon by 2015, and construction on a solar-powered manned research base starting there by 2025. The (very) big bump in the agency's budget will also get spent on tsunami warning technology and other terrestrial communications technology development."
Israel and India also have a pact to reach the moon by 2008 with an unmanned probe (and for a mere $83 million US dollars!) . Maybe reaching the moon is becoming the new "it" thing to do for goverments, much like becoming a nuclear power once was (or is)?
There's the 1979 Moon Treaty - see wikipedia.

I remember that back in the 1980's it was said that the United States was planning to have a moon base by the year 2000.
Look where that ended up.
So, as for the Japan's plan for a moon base, I'll have to see the thing actually under construction before I believe it. I find the robotic probe plan to be much more realistic. I think they have a pretty good chance of succeeding there.
Yes, titanium sponge is a lot harder to work with than aluminum. It pushes the difficulty to the initial costs. You still get the lower maintainence and greater payload, however. Plus, the new method of direct electrolysis can easily produce titanium metal powder for powder metallurgy.
Good quality titanium welds are doable; you just need people properly trained and with proper equipment - you need to weld in very pure argon (applied both front and back), you need to clean the area with good solvents beforehand, you need to keep the argon flowing until the metal is relatively cool, etc. Plus, at all times, you want to use gloves when handling the titanium to be worked (to prevent chlorine corrosion from perspiration) and avoid contamininating it by using aluminum tool surfaces (frictional heat from working with tools can cause localized alloying). In short, you need to use clean conditions and use good tools - something NASA excells at.
Also, a nice thing about titanium is that impurities produced marked discolorations, making a poor weld or corrosion easy to spot. This is a whole lot better than aluminum fatigue, which you need specialized equipment to determine.

Don't take a knife to a gunfight, or even a knife to a knife fight. Take a gun to a knife fight.
As an American, all I have to say is, "leave it to the Japanese to take massive steps towards furthering the human race while the rest of us are stuck here fighting amongst ourselves."
Please be sure to pass that along to the Japanese troops that are in Iraq right now. Because they, like us, know that things like space exploration, and liberating places like Iraq from corrupt regimes are not mutually exclusive. Read the damn news, why don't you? The Japanese are still embarassed by the last war they started, but they understand the need to get involved the "fighting amongst ourselves" so that it can be stopped. Doing so, just as ending the Soviet rule of Eastern Europe, brings huge peace dividends: which we can spend in space (I hope!). Less turmoil, and fewer crazy tyrants with pet oilfields in the world is crucial if we want to really focus on things like space. But we can work on both at the same time.
Don't disappoint your bird dog. Go to the range.
There is a reason's Columbus' home country of Portugal refused to fund his voyage. (Portugal was a major power at the time, they had the money, perhaps more than Spain) In fact, it is the same reason Spain's King refused to fund the mission until his wife got interested.[1]
The kings were well aware that the earth was round, and they knew how big the earth was. This was calculated about 200BC(IIRC). Columbus calculated the earth's size at about 1/4th the correct size. With the correct size it isn't worth sailing around the world to get to Asia, with Columbus' size it was.
When Spain finally gave Columbus sponsorship they gave him junk ships and essentially prisoners as crew. As they watched him leave they were fully expecting that he would starve to death on the trip. (And if you read the accounts it is clear they came close) Spain was surprised when he came back reporting he found land.
[1]Those who are married can understand why you would pay for a stupid mission if you wife was interested.
On Columbus (actually "Colon" - he was not Italian), he had been part of Prince Henry's navigation school (an evolution of the Portugeuse Templars - the Order of Christ), Colon learned the new sailing skills and also saw maps that the prince collected. Colon also took part in a 1477 trip from Norway (royalty linked to Portugal), to Iceland and probably beyond. Colon probably heard northern seamen's tales of vast land beyond the "land of cod" that we now call the Grand Banks. The Vikings and later Scandinavians had been travelling the whole northern arc of the Atlantic from at least 800AD onward, with fishermen from Bristol, the Shetlands and Orkneys, Norway, Bremen and Basque following from at least the 1300s. Supposedly the permission letter from Ferdinand and Isabella granted him to go claim the lands he had already discovered (past/present tenses being important in Spanish). Colon's calculation of the size of the Earth and his brother's maps were largley political, IMHO - they were trying to sell this trip any way they could.
Colon wasn't the only southern European traveller to the Americas in the late 1400s, either. The whole Atlantic had been a Portugeuse pond from the 1450s onward. The settlement of the Azores and Madieras spawned plenty of journeys that included possible settlement in Puerto Rico and the discovery in the 1470s of "Lavrador" by Juan Corte Real, sailing a privately funded mission. Maps from the 1400s (based on Ptolemy even) show the Americas as a third peninsula hanging off China - the oldest sometimes just show Mexico and isthmus of Panama, the later ones (1448 Walsperger, IIRC) have complete maps of S. America rivers and coastal N. America labelled as "India Meridionalis".
What Columbus/Colon did was not original but part of a spectrum of trips that were taking place at the time. The Portugeuse contibution is obscured because of the Lisbon earthquake and the fact that much of the School of Navigation's work was a state secret. An argument could be made that the only thing Columbus did was commit an act of supreme treason against the Portugeuse Crown.
ObSpace: we can draw VERY important lessons from exploration and frontiers of the past - but the new situation is equally different in nature. "Space" still needs to pay for any of us to be able to go - so NASA, JAXA, ESA are only going to be bit-players in a truly space-faring future.
