              Possible launch from shuttle in 1995, AXAF is a space
              observatory with a high resolution telescope. It would orbit
for
              15 years and study the mysteries and fate of the universe.
+
+         o Clementine II
+             Preliminary studies for a Clementine II mission have been
done
+             by JPL. These studies envision a launch in July 1995, flyby
of
+             the asteroid Eros on March 13, 1996, and flyby of the
asteroid
+             Toutatis on October 4, 1996. Clementine would deply a probe
to
+             impact Toutatis, and imagery and other measurements of the
+             impact crater and debris would help analyze the composition
of
+             the asteroid.
+
+         o Pluto Fast Flyby (PFF)
+             Possible launch in 1999-2000 (if a 1996 new start is
+             authorized). Calls for launch of two ~110-150 kg spacecraft
+             using Titan IV/Centaur or Proton (both with additional solid
+             kick stages) in 1999-2000 and encounters with Pluto and
Charon
+             around 2006-8. Flybys would be at 12-18 km/second; data would
be
+             recorded onboard the probes during the short encounters and
+             returned to Earth slowly (due to low power, small antenna
sizes,
+             and large distances) over the next year or so.
+
+             Science objectives include characterizing global geology and
+             geomorphology of Pluto and Charon, mapping both sides of each
+             body, and characterizing Pluto's atmosphere (the atmosphere
is
+             freezing out as Pluto moves away from the Sun, so launching
+             early and minimizing flight time is critical for this
+             objective). The 7 kilogram instrument package might include a
+             CCD imaging camera, IR mapping spectrometer, UV spectrometer,
+             and radio science occultation experiments.
+
+             The PFF spacecraft would be highly miniaturized descendant of
+             the present class of outer solar system platforms, breaking
the
+             trend of increasingly complex and expensive probes such as
+             Galileo and Cassini.
