Japan Successfully Deploys First Solar Sail In Space

An anonymous reader writes "This morning the Japanese space agency, JAXA, successfully unfurled a solar sail in space for the first time. Solar sails offer the best hope for deep space exploration because they eliminate the need to carry fuel. The Japanese spacecraft IKAROS created centripetal force by spinning, allowing it to launch the 0.0003-inch-thick sail. While deployment is a challenge in a zero-gravity environment, spacecraft — unlike airplanes — don't have to contend with drag, so with each photon that hits the sail helps the spacecraft gather speed."

    Did anyone else have the thought that, here are the Japanese, designing and building spacecraft to further explore our Universe and progress mankind's knowledge.

    Here are we, the US, once the leaders of space exploration, have spent billions of dollars to go back and relive some glory (Moon shot) and canceled that, we have canceled the Shuttle program with no other vehicle to replace it, and in the process put a halt to much basic research.

    We're kind of like that pathetic ex High School jock that's trying to relive his glory days.

      I found your statement to be amusingly ironic. Only on /. would it be rated 'insightful'.

      First, please understand that Americans are generally staggeringly provincial; most Americans don't (and never will) own a passport. Most will never leave the US, because they don't have to. Most do not speak a foreign language. Contrary to the view of 'world citizens' like many Euros (as well as a significant number of patronizing, elitist Americans), this isn't because the bulk of Americans are stupid hicks, they simply don't need these things. Everything they can do, need to do, and want to do, all can take place within the comfortably-broad confines of US borders. If they're feeling slightly adventurous, they can go to Canada (barely another country) or even Mexico (where most vacation destinations are less hispanic than Laredo, TX anyway).

      So to your point, regarding Americans' 'inability to imagine a non-American English speaker', of course they don't generally assume that, it wouldn't make any sense for them to do so in context.

      Secondly, what other countries seem to interpret as arrogance appears to be some sort of reverse projected narcissism: "OMG you are so self-centered, you never notice me!"...and if you don't get the irony in that statement, well, then you're hopelessly humorless.

      To suggest that lack of regard equals arrogance is naive, presumptuous, and ultimately self-defeating. To then use THAT as a motivation to generically HATE someone, based on nothing more than their country of origin? I'd call that a self-justifying conceit - dare I call it arrogance? - itself.

      Get over yourself - nobody automagically is entitled to that level of importance; not Americans individually, and certainly not you.

  2. Ya! The US has done nothing! by Sycraft-fu · · Score: 5, Insightful

    I mean they most certainly didn't recently deploy two rovers to Mars that WILDLY exceeded expectations. They didn't then also deploy another, fixed, lander which while not as wildly successful exceeded it's planned mission significantly. Nope, none of that happened...

    Oh wait, yes it did.

    Please, while the US space program is not without troubles, it isn't as though it is at a standstill. NASA continues to do some amazing work, and much of it like the landers are pure science, to further our knowledge.

    Stop with the US hate that is so popular on Slashdot. The US is not perfect, no nations is, indeed no human endeavor is. There's plenty to criticize and that includes in the space program. However trying to pretend as though they accomplish nothing of note is silly. Two successful recent Mars missions shows that. No, they weren't manned, neither is this Japanese craft. Putting people in space is dangerous and often not worth the expense. We can learn a lot with remote operated equipment.
