- As funding for NASA dwindles in the United States, and more countries become space-
- faring nations, we emerge in a time when there is no superpower in space. Rather, we
- venture out as a multinational people, driven by the same human urges to explore the
- unexplored.
-
- Although ideas for space probes, satellites, and other types of missions are bountiful, funds
- are increasingly limited. A recent proposal made by JPL was the Comet
- Rendezvous/Asteroid Flyby (CRAF) mission. Although the scientific merits for this
- mission were very high, and the gain in knowledge would have been great, it was canceled
- for a perceived lack of money.
-
- The CRAF probe was designed on the new generation of Mariner Mark II spacecraft, and
- would have been a joint NASA-ESA mission. The probe was to have launched in 1996,
- flying close to a main-belt asteroid on its way to intercept Comet Tempel 2 in the year
- 2003. CRAF was to accompany the comet from near the time of aphelion (its furthest
- point from the Sun) until after it had rounded the Sun on its long elliptical orbit.
-
- One of the most interesting components of the CRAF probe was a small penetrator that
- would be fired straight into the heart of the comet. This bullet-shaped instrument would
- have penetrated the surface of the cosmic snowball, returning the first direct
- measurements of a comet.
-
- By the time the mission had finished, we would have learned a great deal about the
- medium of space debris around the outside of our Solar System, and perhaps more about
- the material makeup of our Universe. In 1992, the out-going U.S. administration deleted
- CRAF from its list of funding requests, thus killing the project.
-
- However, while governments fluctuate, science presses forward. There will no doubt be
- more ideas for comet research, and more daring and innovative probes will be built.
- Nonetheless, without public interest, it will be difficult to attain government support.
- Perhaps in the future, more educated citizens will see the material and intellectual benefits
- of space exploration, as well as the adventure.
