		Gehrels' work at observatories and universities in the United States of America, India, Sri Lanka and elsewhere leads him to refelect on the research enterprise as well as more fundamental questions.
		With regard to the ongoing efforts of the United Nations, Japan, and Sri Lanka to establish a National Astronomical Observatory at Sri Lanka in 1995, the following is quoted from chapter 19.

		So far, Gehrels and his colleagues have calculated there are about 1,700 potentially threatening objects--asteroids and comets one kilometer or larger in diameter--orbiting the sun.
		Unfortunately, Gehrels and his colleagues have been unable to find a government agency--or, more likely, a wealthy donor--willing to pop for that $730,000 in hardware that one day may help save the planet from a real cosmic Armageddon.
		Gehrels, intent on his incoming computer images as he sat atop Kitt Peak one clear night last week, merely laughed at the suggestion.

		Dr. Neil Gehrels of CGRO is the son of Dr. Tom Gehrels of the University of Arizona.
		Since he's long had research interests in asteroids and other solar-system astronomy, Tom is the one more likely to have discovered a comet (and thus had his name attached to it).
		Tom Gehrels is a leader in the Spacewatch project, which has recently increased mankind's discovery rate on near-Earth asteroids (they're finding a couple every month).

		He developed that paper in a class at Leiden University in The Netherlands, where Gehrels (1988) had the fortune to be one of the few undergraduate students attending that class.
		In any case, the effects of such distant encounters have been modeled to show that the cometary orbits may be perturbed to be either tossed out of the solar system, or to be brought into elliptical orbits toward the inner regions of the solar system.
		At the time of the dedication of the 1.8-meter and its building, Gehrels made a wager with representatives of the Tohono O'odham Nation that within 20 years there will be a Tohono astronomer working in that building with that telescope.

	Wired News: Asteroid Flap Reveals Astronomy's Gaps
		And what is right for Tom Gehrels is to lose sleep just before, during, and after each new moon, when the night sky is best for viewing bodies such as stars, meteor showers, and asteroids.
		Instead of relying on automated observations, Gehrels and his colleagues at the Arizona Spacewatch Project split an 18-day viewing period, with each scientist spending six straight days in the observatory watching as the data come in across the computer monitors.
		For Gehrels, the six contiguous sleepless nights are a test of mental mettle, an exercise of will, and, if nothing else, a period of deep meditation.

		A member of the Dutch resistance during World War II, Gehrels readily acknowledges von Braun's contributions to the world of science, but is all too aware of the little-known dark side of both him and his brother Magnus.
		It is Gehrels who has pieced together that truth, largely from interviews with surviving political prisoners who had been forced to build V-1s and V-2s under the supervision of the von Brauns in an underground complex near Nordhausen, Germany.
		These were not ordinary hangings, Gehrels says, "not hanging that breaks the neck of the prisoner, but they were slowly choked to death with a kind of baling wire around their neck."

		He has charged that von Braun bears greater responsibility and guilt for harsh treatment of prisoners than his official "sanitized" biography would imply.

		I would not even call crossing through such emptiness terribly "interesting," which is fortunate for the space probes like Galileo and the Voyagers that have had to do just that.
		Tom Gehrels of the University of Arizona is a veteran asteroid hunter; using the Spacewatch Telescope on Kitt Peak, he and his colleagues find roughly 20,000 objects a year, many of them uncatalogued asteroids.
		Some scientists were seriously concerned about the possible high density of objects in the asteroid belt, which lies between the orbits of Mars and Jupiter, when the first robotic spacecraft were scheduled to be sent through it.

		Astronomers with the Spacewatch project at the University of Arizona in Tucson and the Minor Planet Center (MPC) at the Smithsonian Astrophysical Observatory in Massachusetts have discovered the first new moon of Jupiter in more than a quarter of a century.
		Spacewatch astronomers Jim Scotti, Jeff Larsen, Tom Gehrels, Joe Montani and Spacewatch director Bob McMillan took images of the object, previously designated asteroid 1999 UX18, during their Spacewatch shifts in October and early November 1999.
		MPC astronomers Gareth Williams and Tim Spahr, and MPC director Brian Marsden this week confirmed by orbital calculations that the object is not an asteroid orbiting the sun, but a previously unknown moon of Jupiter, the first found since 1974.
