      |PASADENA, Calif. (AP) - NASA's aging Galileo spacecraft swooped past
      |Jupiter's frozen moon Europa on Monday but apparently did not experience
      |computer problems from the planet's intense radiation.
      |The probe, which has been in orbit around Jupiter since December 1995, flew
      |within 220 miles of the moon's surface, said project manager Jim Erickson
      |NASA's Jet Propulsion Laboratory.
      |``Europa is really just on the edge of the area we consider hazardous from
      |the radiation point of view,'' he said. ``We really thought this one would
      |pretty well, and it has so far.''
      |The spacecraft's computer and instruments appeared to be operating
      |Data collected during the pass was stored aboard the probe's computer to be
      |relayed back to Earth over the next several weeks.
      |Galileo measured Europa's magnetic fields in an effort to detect
      |from a suspected liquid ocean beneath the moon's icy crust. Some scientists
      |believe life could survive in a liquid ocean beneath the frozen surface.
      |During a flyby of the moon Io in November, Galileo's computer entered a
      |safe-mode just before its closest encounter. A similar problem occurred
      |during an October flyby of Io.
      |Engineers now believe they know what caused the problem - a
      |memory chip.
      |``We've got some programs on the ground ready to go that would help us
      |the problem faster than we did the previous time,'' Erickson said.
      |Meanwhile, the space agency has agreed in principle to continue Galileo's
      |operations past Jan. 31, when its current mission was to end. Funding and
      |other details have not yet been worked out, he said.
      |Another Io flyby is planned for Feb. 22, with encounters with Ganymede on
      |30 and Dec. 28. Joint observations with the Cassini spacecraft could take
      |place in December, when the Saturn-bound probe swoops past the giant
