Japan Launches Lunar Orbiter Mission 121

Sooner Boomer writes "In a historic event, Japan today launched its first lunar probe. The mission is nicknamed Kaguya after a fairy-tale princess from Japanese myth. The news media is calling it the 'latest move in a new race with China, India and the United States' to explore the moon (don't forget Google). From the article: 'The rocket carrying the three-metric ton orbiter took off into blue skies, leaving a huge trail of vapor over the tiny island of Tanegashima, about 1,000 km (620 miles) south of Tokyo, at 10:31 a.m. (9:31 p.m. EDT) as it headed out over the Pacific Ocean. The mission consists of a main orbiter and two baby satellites equipped with 14 observation instruments designed to examine surface terrain, gravity and other features for clues on the origin and evolution of the moon. China has plans to launch an orbiter later this year, with unmanned rover lander mission scheduled for 2010. India and the US also have orbiter missions scheduled for next year.'"

    [1]unless of course you're using the weight in orbital mechanics calculations, in which case you'll need better accruacy than the 1 significant digit reported here.

  • Now they will witness the moon bases that NASA has known about for many years. HINT Disclosure project.
  • OK, call me no fun at all, but why the hell is anyone committing major resources to getting to the moon? As far as I understand, we're pretty confident it's a big lump of sand. No real advantage of being there vs being in orbit. Nice place for telescopes maybe, but so is high Earth orbit or a Legrange point. Other than a playpen for new technology, what's the draw? Mars at least has some interesting geology and the whole maybe-there's-microbes thing. But the moon? Lunacy! Why doesn't Google give an X-prize

      Gravity, for one. If you want to have people live there to man your production facilities that require a hard vacuum, having it on the moon is more betterer than having it in orbit.

      Also, the bulk of the moon itself is useful for things like radio astronomy. A radio telescope on the lunar far side would be able to use the entire mass of the moon as a shield against the background noise of the Earth.

      Other than that... It's just damn cool! Go outside some night and really take a look at the moon. It's the

BLISS is ignorance.

Working...
