NEW IMAGES SUGGEST PRESENT-DAY SOURCES OF LIQUID WATER ON MARS

     In what could turn out to be a landmark discovery in the
history of Mars exploration, imaging scientists using data from
NASA's Mars Global Surveyor spacecraft have recently observed
features that suggest there may be current sources of liquid water
at or near the surface of the red planet.  The new images show the
smallest features ever observed from martian orbit –- the size of
an SUV.  NASA scientists compare the features to those left by
flash floods on Earth.  "We see features that look like gullies
formed by flowing water and the deposits of soil and rocks
transported by these flows. The features appear to be so young
that they might be forming today. We think we are seeing evidence
of a ground water supply, similar to an aquifer," said Dr. Michael
Malin, principal investigator for the Mars Orbiter Camera on the
Mars Global Surveyor spacecraft at Malin Space Science Systems
(MSSS), San Diego, CA.  "These are new landforms that have never
been seen before on Mars."  The findings will be published in the
June 30 issue of Science magazine.

NASA FORMS TEAM TO REVIEW SPACE SHUTTLE MAIN ENGINE TEST INCIDENT



--------------------------


NASA FORMS TEAM TO REVIEW SPACE SHUTTLE MAIN ENGINE TEST INCIDENT

Robert Sackheim, assistant director and chief engineer for
propulsion at NASA's Marshall Space Flight Center, Huntsville, AL,
will lead a team to review the automatic shutdown of a recent
Space Shuttle Main Engine test at NASA's Stennis Space Center, MS.
At about 5 seconds into the planned 200-second test of a new high-
pressure fuel turbopump configuration, higher than expected test
temperatures caused the Shuttle Main Engine to shut itself down
using its own internal safety mechanisms.

(Phone: 202/358-0243).

Malone (Phone: 256/544-0034).
