Japan Space Yacht IKAROS (Video) Set For Blast-Off Today
"Interplanetary Kite-craft Accelerated by Radiation of the
Sun - is a high tech space yacht, or kite, that will be sent into space by a rocket today (May 18) and gather its energy from the particles putting pressure on its sails." See: http://www.postchronicle.com/news/or....shtml?rssfeed So.... having a sail makes it a Yacht? |

Next launch attempt on Thursday, May 20 at 5:58 pm EDT. Not wanting to use it in inclement weather - aye, that's a point in favor of it being a yacht. -- djb@ | Dan Birchall, Night Operation Assistant, Subaru Telescope/NAOJ. naoj | Views I express are my own, obviously not those of my employer. ..org | Our atmospheric inversion layer keeps silly people below 3000m. |

So, once under way, a solar flare or mass ejection would be the equivalent of catching a puff? rick jones -- It is not a question of half full or empty - the glass has a leak. The real question is "Can it be patched?" these opinions are mine, all mine; HP might not want them anyway... feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... |

...

See: http://www.postchronicle.com/news/or....shtml?rssfeed So.... having a sail makes it a Yacht? Seems like a light sail, not a solar wind sail. Which is sensible since sunlight has an order of magnitude or higher momentum flux than the solar wind, gusty as it is, has on average, and can much more easily control the thrust vector than I suppose some sort of magnetic mesh can control the solar wind thrust. But the language in the article, although not directly specifying, indicates that the solar wind is used. Did some journalist not do his homework properly, or did I not? Jon Lennart Beck. |

So, once under way, a solar flare or mass ejection would be the equivalent of catching a puff? That's a good question... It would depend on whether the material hitting the sail ricocheted off of it, adding to its velocity, or got absorbed by it, adding to its velocity, but also increasing its mass. I imagine that will be one of the interesting aspects of the flight for them to monitor, as this is the first time anyone has tried something like this on any sort of large scale. Several years back I read an article by a scientist who thought the whole theory that solar sails were based on was wrong, and it just won't work. The will be quite surprised if that's the case. :-D Pat |

What amazes me is not only is this a solar sail utilising ultrathin and lightweight materials, but it also incorporates thinfilm solar cells within the structure for electricity generation. To top it off it only cost $16 million. |
