COOL. I'm having trouble connecting though. What is the 'external source'? How reliable is it? I have never seen this before. It is
interesting.

The most disturbing element of the transmissions is that the object casting the shadow literally seems to change direction as it crosses over Sojourner. NASA officials doubt that any natural or meteorological phenomenon could explain the Martian shadow.
"It was just too weird," said an unnamed source at NASA. "The way the shadow crossed over Sojourner indicated that Sojourner itself was under observation, almost as though another probe were photographing our mission."
Could it have been a secret involvement by the then Soviet Union, or was it an extra-terrestrial craft?
