Scientists Fly to 2008's Most Dazzling Meteor Shower 124

Posted by samzenpus from the follow-that-burning-rock dept.
coondoggie writes "On Thursday, SETI Institute and NASA scientists will take their research instruments and their coffee for a 10 hour continuous flight to map what they say will be the earth's most brilliant meteor shower of 2008. Scientists believe the Quadrantid meteor shower could flash over 100 visible meteors per hour at its peak, depending on location. A Gulfstream V aircraft will take off from San Jose, Calif., and fly 14 scientists and their instruments for 10 continuous hours at 47,000ft., over the Arctic and back to San Jose. The primary goal of the lengthy airborne mission is to observe the Quadrantid meteor shower in ideal and virtually unchanging conditions far above light pollution and clouds to determine when the meteor shower peaks and how the flow of meteors are dispersed."

          They have high-powered telescopes in areas with low light pollution, but these telescopes have a fixed position. Over the course of 10 hours, the Earth rotates quite a bit (10/24ths!), so the area of the Earth that is prime for observing the meteors moves over a large distance during the course of the shower.

          Planes can also fly above weather, whereas telescopes cannot see through many weather phenomena.

          Given the kind of costs that research entails, a flight like this probably isn't all that expensive.
          • The flight wasn't expensive until they requested a glass dome to replace the ceiling of the plane so they could actually see the shower. They eventually came to a compromise and went with a convertible top; we'll get to see how that plays out shortly.
        • Actually on the ground the lowest light one can be exposed to is still much brighter than natural darkness - you simply cannot escape the light pollution on the surface of the planet save for possibly in antartica or the middle of the pacific. The was actually a slashdot article on the subject a few months ago. Also, the telescopes are made to compensate for clouds and smog, but they can't slice through it. They're also subject to weather.

But even the largest observatories are facing problems where the surroundings have become increasingly densely populated and light polluted over the years.

          Actually telescopes, binoculars, etc, are a lousy way to watch a meteor shower. The viewing area is just too small compared to the area across which the meteors streak, and the chances of one actually crossing the viewing area is negligible. Whether you're a city dweller doomed to seeing only fireballs, or a rural farmer who gets to see every last dust particle burning in the upper atmosphere, the naked eye works better.

      • Yeah, this makes sense to me. I thought of this after I posted the question. The applet is probably adjusting for the fact that it might be daylight at my location when the meteor shower peak intensity for the planet. So, even though the two predictions for peak activity are 4 hours and 40 minutes apart, the different peaks at my location are only 24 minutes apart. Thanks for the feedback.
  • I heard in 2007 that there was a serious threat of SETI being shut down for lack of funding.

    If this is how they're spending it, they should be. I'm a staunch technophile, and I believe SETI is worth doing but a junket is a junket and wasted TAX DOLLARS is bullshit.

    A ten hour flight in a government/private Gulfstream over the arctic to view a meteorite shower?

    What, pray tell, do they expect to learn?
  • A Gulfstream V aircraft will take off from San Jose, Calif...The primary goal of the lengthy airborne mission is to observe the Quadrantid meteor shower in ideal and virtually unchanging conditions...

    Those ideal conditions specifically being the well-stocked supply of canapés and booze in that private jet.
  • OK, one obvious question: why the heck does SETI Institute sends people to watch a meteorite shower? They expect to see alien ships there or what?

      Because the SETI institute isn't, contrarily to popular belief, just about finding aliens. I'll quote their mission statement for you:
      "The mission of the SETI Institute is to explore, understand and explain the origin, nature and prevalence of life in the universe."

      The alien part (SETI research) is just a subsection of broader research, just like astronomy (and that's what this is about) is.
  • Listen to it here: http://science.nasa.gov/audio/meteor/navspasur.m3u [nasa.gov] This link is audio detected with an ICOM R-8500 receiver tuned to 217.927 MHz SSB. The antenna is a 13 element 220 MHz. beam pointed upward and to the east. The CW signal is from a Space Radar facility in Lake Kickapoo, TX, formally called NAVSPASUR. It is now operated by the USAF.
  • Must say, I'm impressed. Anyone under 40, these days, spells (and pronounces) it, 'Artic' which is actually an Articulated Lorry.
