NASA'S RESPONSE TO UPI'S MARCH 21 MARS POLAR LANDER STORY

     James Oberg of UPI claims that NASA knew there was a problem
with the Mars Polar Lander propulsion system prior to the Dec. 3
landing attempt and "withheld this conclusion from the public."
NASA categorically denies this charge.  Propulsion system issues
were addressed in the Nov. 10, 1999 press conference that released
the Mars Climate Orbiter Mishap Investigation Board's Phase 1
report (known as the Stephenson report). Independent Mars Program
review teams looking into this issue have conducted intensive
reviews related to Mars Polar Lander, and their teams have
surfaced no evidence relating to thruster acceptance testing
irregularities as alleged by UPI. In fact, members of the review
teams are using words like "bunk," "complete nonsense," and
"wacko" to describe their reactions to UPI's charge.

NEW CLASS OF GAMMA RAY OBJECTS DISCOVERED IN MILKY WAY

     The exotic world of gamma-ray astronomy has taken yet another
surprising turn with the revelation that half the previously
unidentified high-energy gamma ray sources in our own galaxy, the
Milky Way, actually comprise a new class of mysterious objects.
The discovery of this new class and speculation regarding its
qualities appear in the March 22 issue of Nature.
