Meteorite provides new information about space

     WASHINGTON, April 24 (AP): Scientists reported that a 35-pound
meteorite that fell near Lost City, Okla., last January has provided
valuable new information about space.
     They said it has yielded the firmest evidence yet concerning the
intensity of cosmic rays far beyond the sun - raising the possibility that
manned spaceshopes venturing to planets beyond Mars might have to be
armoured against swarms of high-energy space bullets.
     Come from beyond Mars, the meteorite struck the earth in three pieces,
the largest about 20 pounds.
     It is estimated to have weighed about 500 pounds originally, and is
presumed to have been a fragment of an explosive collision between two huge
objects some six million years ago. This theory, the scientists said, comes
from calculations of the object's exposure to cosmic rays.


     The meteorite was found by one of the scientists on a snow-covered road
outside Lost City on January 10, six days after it reportedly flashed rather
spectacularly as a fireball streaming down through the winder atmosphere.
     It is the first meteorite in history for which the original orbit in
space - and trajectory to the earth - has been computed with high accuracy.
Indeed it is only the second much meteorite for which even an estimated
orbital and trajectory cmputation has been possible.
     This is so because it is the first to have been photographed in flight
by a special American meteor-tracking network set up only a few years ago.
The only other recovered meteorite that was photographed in flight was one
that fell in Czechoslovakia in 1959, but scientists said this was an
accidental sighting using cameras designedfor another purpose. And they
said that meteorite's pathway to the earth is still uncertain.
     Scientists of the Smithsonian Astrophysical Observatory have calculated
that the meteorite whissed earthward from an orbit some 65 million miles
beyond the planet Mars. Dr. Philip J. Cressey of the Goddard Spaceflight
Centre, Greenbelt, Md., chairman of the session told a newsman:
     "It's a known space probe...we know exactly its trajectory through the
earth's atmosphere and we have a good orbit on where it came from. And
right now, we do not have any earth-launched space probe that has gone
beyond the orbit of Mars."
