Meteorites Shot From Plane To Gauge Size of Real Meteors

     CAMBRIDGE (AP) - Miniature meteorites shot from the nose of an Army V-2 
rocket 40 miles in the air - soon may aid scientists in determining the size 
of real meteors.  Dr. Fred L. Whipple of the Harvard College Observatory 
said a test will be conducted Dec. 17 at White Sands Proving Grounds, New 
Mexico.
     Information about many phenomena of the upper atmosphere, including 
reactions of the atmosphere to moving bodies passing through it, may be 
obtained during the 30 seconds of the rocket's ascent, Dr. Whipple added.  
The experimental rocket will begin to throw out the "meteorites" in swarms 
when 20 miles up, he said, continuing to do so until it reaches a height of 
40 miles.  The man-made iron missiles have been set to fire from the rocket 
head at the same speeds at which natural meteors enter the earth's 
atmosphere.

To Compare Light

     Two aerial cameras - fitted with rotating shutters covering an area of 
40 to 45 degrees of the sky - will record the flight of the missiles.  By 
comparing the brightness of the artificial meteors, scientists hope to 
determine the size of real meteors.
     "At the present time," Dr. Whipple explained, "the sizes of observed 
meteors are calculated from theoretical information only.  The heights, 
brightness, speeds and rates of slowing down can be measured directly."
     Discovery of reactions of the upper atmosphere to moving bodies passing 
through it, and elimination of guesswork on the actual sizes of natural 
meteors are the hoped for results of the New Mexico experiment, Dr. Whipple 
said.

The NPA in the subject line, stands for Newspaper Article. The old list 
server allowed us a search feature the current does not, so I guess this is 
more for quick reference and shortening the subject line now.
