      Greetings from the busy world of NASA HQ Space Science!

      New in the last week at http://spacescience.nasa.gov/ :

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

      Research just published using Mars Global Surveyor data suggests that
      volcanoes were more important than previously thought in shaping Mars'
      early geology and climate. Story at

      Links to the Advanced Solar Coronal Explorer (ASCE) mission and the Swift
      Gamma Ray Burst Explorer mission, both currently under study in our
      Explorer program, and to ASPERA-3, a Discovery Mission of Opportunity
      planning to fly on the European Mars Express mission, are now on our
      Missions pages.

      Stardust, launched February 7, is in excellent health. You can keep on top
      of the latest news (until comet arrival in January 2004!) at

      The Space Science Enterprise Integrated Technology Strategy document is now
      online. Learn fascinating facts about our technology programs. Yippee!
      Pretty decent .html, way better than mine, at

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

      As you may know, a launch delay with a different spacecraft has had a
      domino effect on our WIRE galaxy survey mission, pushing it back a few days
      to March 1 or 2. Follow WIRE at http://www.ipac.caltech.edu/wire/

      Cheers!

        Greetings!

        New in the last week at http://spacescience.nasa.gov :

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

        The European Space Agency (ESA) has signed a contract with Matra
        Marconi Space (MMS) to design and build the Mars Express spacecraft in
        time for launch in June 2003. This could be good news for a potential
        U.S. contribution to the ASPERA-3 instrument, currently under study in
        our Discovery program.

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

        Deployment of the high gain antenna on Mars Global Surveyor went well,
        and the spacecraft should soon be sending back streams of Mars images.

        Huge Spring Storms Rouse Uranus from Winter Hibernation - Uranus'
        seasons are many Earth years long because of the planet's 84-year long
        orbit, and also greatly influenced by the extreme tilt of the planet's
        axis. This fascinating Hubble animation is based on images taken from
        1994 through 1998 in both visible and near-infrared light. It's a big
        download, but I thought it was well worth it. Full story and
        animation at http://oposite.stsci.edu/pubinfo/pr/1999/11/index.html

        A study of comet Hale-Bopp suggests that comets did not give Earth its
        water, supporting other recent studies but contrary to the
        longstanding belief of many planetary scientists. Caltech press
        release at http://www.caltech.edu/~media/Press_Releases/PR11963.html

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

        Galileo finds 'bottle blonde' chemical (hydrogen peroxide) on Europa -
        a "weird" chemical, the presence of which is attributed to the intense
        radiation environment.

        JPL press release at
        http://www.jpl.nasa.gov/releases/99/europaperoxide.html Galileo page
        at http://www.jpl.nasa.gov/galileo/

        The Galileo folks have also built a nifty multimedia educational page
        about Europa's geology at http://www.jpl.nasa.gov/galileo/wedges/

        NASA Experiment Lays Groundwork for 'Living Off The Land' on Mars - a
        recent successful test of an experiment to make oxygen from Mars' thin
        atmosphere. The experiment will eventually be carried on our Mars
        Surveyor 2001 Lander mission. Such technology might eventually make
        oxygen for breathing and/or propellant.

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

        Finally, it looks like the launch of TERRIERS is going to slip a few
        days beyond April 12 due to recent glitches with both the rocket and
        the spacecraft. The new date should be announced soon. TERRIERS is at
        http://net.bu.edu/terriers.html

          Our Galaxy Evolution Explorer (GALEX) Small Explorer mission has
          completed its preliminary design work. After a presentation last week
          here at NASA HQ, the mission received the go-ahead for development.
          GALEX is an ultraviolet mission that will map the history and probe
          the causes of star formation over the last 80% of the life of the
          Universe, the period over which galaxies have evolved dramatically,
          and the time that most stars, elements, and galaxy disks had their
          origins. Launch is expected in September 2001. GALEX is at
          http://www.srl.caltech.edu/galex/

          Astronomers at NASA and Carnegie Mellon University have independently
          found evidence for a mysterious new class of "middleweight" black
          holes, weighing in at 100 to 10,000 Suns. HQ press release at
          ftp://ftp.hq.nasa.gov/pub/pao/pressrel/1999/99-051.txt

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

          Launch of TERRIERS has been postponed until no earlier than April 22
          because of launch vehicle concerns. Follow developments at
          http://net.bu.edu/terriers/launch.html

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

          A study in the April 9 issue of Science magazine suggests that the
          variations in the energy given off from the sun affect the Earth's
          wind patterns and thus the climate of the planet. A connection
          between solar output and climate has long been suspected. A good
          summary is at http://www.giss.nasa.gov/research/intro/shindell.03/

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

          Astronomers have pieced together evidence of a 700-year-old supernova
          that was nearly as bright as a full moon, undocumented by early
          stargazers and unknown to modern-day astronomers until only very
          recently. A bit of a mystery at
          ftp://pao.gsfc.nasa.gov/pub/pao/releases/1999/99-037.htm

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

          "Supernova? We don't need no stinkin' supernova!" Astronomers using
          data from ROSAT, HST, and Kitt Peak have detected the first
          observational evidence for the remnants of a HYPERnova, an explosion a
          hundred times more energetic than a supernova. This could provide
          better understanding of the dynamics of star explosions and begin to
          unlock the mystery of the gamma ray burst (GRB) phenomenon. More news
          at ftp://pao.gsfc.nasa.gov/pub/pao/releases/1999/99-035.htm

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

          This afternoon, more than two dozen researchers showed off their
          science and fielded questions from students during a live television
          program and Internet event shot on location from NASA Goddard. "Live
          from the Sun -- Solar Studies and Sunny Interactions" was broadcast
          nationally on April 13, from 1-2 p.m. Eastern Daylight Time, on
          participating PBS stations. Hopefully it reached a lot of schools.
          It's going to be replayed on NASA TV on April 26; check the schedule
          and description at
