      HOW QUICKLY THEY GROW UP
      -------------------------
      I know it's been a few months, so here's another update on our
      little Chloe - now 4 and a half months old. As you can see,
      she's a bright one, and fills in for me on the newsletter during
      busy days. Seriously, she loves to type at the keyboard and I'll
      of ten get emails from her at work. (Okay, her mom prepares the
      message but she handles the content. "zzzzzzzzzzzzz z
      mzzmzmzmmjjdjdjd" was a classic.) I especially love her dinosaur
      sleeper.

      JUPITER'S X-RAY HOTSPOT PUZZLES ASTRONOMERS
      -------------------------
      A new image taken by the Chandra X-Ray Telescope shows puzzling,
      pulsating hotspots at Jupiter's north and south poles. So far,
      scientists have no explanation for what could be causing these
      X-rays; although, they do coincide with other phenomena seen on
      the planet, including auroras; like those at the Earth's poles.

      NASA TRIES TO CONTACT PIONEER 10
      -------------------------
      Later this week, NASA scientists will attempt to contact the
      distant Pioneer 10 spacecraft, which was launched 30 years ago.
      The team will try to reach the spacecraft by focussing a radio
      telescope at the Jet Propulsion Laboratory�s Deep Space Network
      (DSN) in Madrid, Spain. Launched on March 2, 1972, Pioneer 10 is
      now 11.9 billion kilometres away from the Earth and hasn't been
      heard from since April 2001.

      JUPITER IS BUFFETED BY SOLAR WIND
      -------------------------
      Scientists have uncovered the workings of an invisible bubble of
      charged particles that surround Jupiter and interact with the
      solar wind. This bubble is called the magnetosphere and extends
      to a distance of 100 times the diameter of Jupiter itself. 14
      months ago, two spacecraft: Galileo and Cassini took
      simultaneous readings of the giant planet's magnetosphere from
      different vantage points. Detailed results of their findings
      will be published in scientific journals in the next few days.

      ARIANE 5 ROLLED OUT TO LAUNCH PAD
      -------------------------
      An Ariane 5 rocket carrying the European Space Agency's Envisat
      satellite, Europe's largest and most expensive satellite was
      rolled out to the launch pad yesterday. If all goes well, the
      rocket will launch Friday morning at 0107 GMT (8:07 EST Thursday
      night) from Kourou, the European spaceport in French Guiana and
      carry the 8,000 kg satellite into orbit. Envisat will spend the
      next 5 years monitoring the health of the Earth's oceans, ice
      caps, land and e vironment.

      BRIGHTEST FULL MOON THIS YEAR
      -------------------------
      The full moon on February 27 is going to be the brightest one of
      2002. The moon's orbit isn't a perfect circle; over the course
      of its 28-day trip around the Earth, its distance varies from
      406,700 km to 356,400. And today's full moon happens to coincide
      with the closest point of that orbit, making it 20% brighter
      than an average full moon.

      COLD WEATHER DELAYS SHUTTLE LAUNCH
      -------------------------
      Unusually cold weather in Florida has forced NASA to push back
      Thursday's launch of the space shuttle Columbia for its service
      mission to the Hubble Space Telescope. Officials are predicting
      temperatures only a few degrees above freezing, but
      significantly warmer on Friday (cold weather was a contributing
      factor to the Challenger disaster). During the 11-day flight,
      astronauts will add $172 million in upgrades to Hubble. (AP
