	2003 DPS Prize Winners
		Ostro has been a pioneer and principal driving force in the area of planetary radar astronomy and continues to push the capabilities of this field to new heights.
		Ostro and his colleagues have successfully obtained radar echoes from nearly 200 asteroids, mostly ones that cross Earth's orbit but also including many in the main asteroid belt between Mars and Jupiter.
		Ostro is a New Jersey native who earned bachelor's degrees in liberal arts and ceramic science from Rutgers University, New Brunswick, N.J.; a master's degree in engineering physics from Cornell University, Ithaca, N.Y.; and a doctorate in planetary sciences from the Massachusetts Institute of Technology.

		Ostro will also report on an asteroid, the size of a baseball diamond, that is the smallest solar system object ever studied in detail.
		Ostro will describe the increasingly important use of radar for imaging when he moderates one of the daily press conferences (Monday, July 26, 10 a.m., 305 Ives Hall) during the ACM.
		Ostro will describe how radar is being used to construct geologically detailed three-dimensional models of distant bodies, including 37 main-belt asteroids and 50 near-Earth asteroids.

	Asteroid 4179 Toutatis
		Hudson and Ostro (1995, hereafter HO95) used a comprehensive physical model to invert the lower-resolution images to estimate the asteroid's detailed shape and inertia tensor, initial conditions for the asteroid's spin and orientation, the radar scattering properties of the surface, and the delay-Doppler trajectory of the center of mass.
		Hudson, Ostro and Scheeres (2003) presented a shape model that incorporates those 17 images as well as lower-delay-resolution (typically 500-ns) images from the 10 dates in 1992 on which no 125-ns images were obtained.
		Using the physical model of Toutatis derived from 1992 radar observations (Hudson and Ostro 1995, Science 270, 84-86) to analyze the new data, we obtain refined estimates of the asteroid's orbit, spin state, and surface properties.

		Ostro and four other Western hikers, including one American, were kidnapped in early July by an unknown group named Al-Faran.
		Kashmiris mourned when Ostro's body was found—calling it a "fl day." The general strike called by the Hurriat conference gave a clear message to the world community that Kashmiris abhor terrorism and criminality.
		Ostro's murderers must be identified, and the guilty punished under law.

	TPS: Very Close Approach by Asteroid 4179 Toutatis (Site not responding. Last check: 2007-11-03)
		According to Ostro, that means that Toutatis could be either an ordinary chondrite -- the most common type of meteorite that fall on the Earth -- or a stony-iron meteorite.
		For Toutatis, Ostro hopes to find a higher density, because if the density he finds is high enough, it would be possible to exclude chondritic compositions and say for sure that Toutatis is a stony-iron object.
		In particular, Ostro believes that "there's probably no way of knowing" whether Toutatis is one funny-shaped asteroid or two asteroids touching "until we send a human crew." There are no current plans for that, but "because it's in the plane of the Earth's orbit it's a good target.

	8/28/95 INDIA: BARGAINING WITH LIVES
		Those with extremely strong stomachs might try to imagine his final sensations: Ostro was kidnapped July 8 by a group fighting for Kashmir's separation from India, and last week his emaciated, beheaded corpse was discovered by peasant women collecting firewood on a remote country road.
		After being identified by his parents, Ostro's remains were flown to New Delhi, where medical examiners concluded that he had been beheaded alive, using the "most barbaric methods." After his death, Ostro's captors carved into the flesh of his abdomen the name of their shadowy, brutal group: al-Faran.
		Ostro's killing galvanized the Indian government, which stepped up both negotiating efforts and military preparedness to help free Ostro's four fellow hostages: a German hiker kidnapped a few hours before Ostro and an American and two Britons taken four days earlier.

	SPACE.com -- City-Sized Asteroid to Pass Earth This Fall
		Steven Ostro at NASA's Jet Propulsion Laboratory has, with Hudson, studied Toutatis via radar on previous flybys.
		Ostro told SPACE.com that the population of near-Earth asteroids -- hundreds bigger than 0.6 miles (1 kilometer) have been found in the past six years or so -- are now known to come in "a zoo of shapes." And there are other asteroids that don't rotate on a single, main axis.
		Ostro points out a simple relationship between the distance of Toutatis at this close approach and the size of the Moon.

	Asteroid Radar Astronomy
		Radar evidence for a metallic composition of the near-Earth asteroid 1986 DA was presented by Ostro et al., [1991b] using Arecibo Observatory's 13-cm radar.
		An unmodulated, continuous wave was transmitted to the asteroid and the distribution of echo power as a function of frequency was measured.
		Ostro et al., [1993], using simultaneous radar return reception at two antennas, acquired interferometric data producing the highest radar resolution images of an asteroid to date (Figure 3).

	Sun never sets, for long, on fast-spinning asteroid
		Publishing their findings in tomorrow's issue of Science magazine, Dr. Steven J. Ostro of NASA’s Jet Propulsion Laboratory, Pasadena, CA, and an international team of astronomers used a radar telescope in California and optical telescopes in the Czech Republic, Hawaii, Arizona and California to image the 30-meter (100-foot), water-rich ball as it twirled through space.
		Ostro and his colleagues used the 70-meter-diameter (230- foot) Goldstone, CA, antenna of NASA's Deep Space Network to transmit radar signals continuously to the asteroid and turned a 34-meter-diameter (112-foot) antenna on it to collect echoes bouncing back from the object.
		Tracking of 1998 KY26 by Ostro and his colleagues in the international scientific community was supported by NASA's Office of Space Science, Washington, DC, and by the Czech Republic's Academy of Sciences in Prague.

		Radar images of the three-mile-long (4.6-kilometer-long) asteroid suggest it could be composed of two or three space rocks held together by gravity.
		Ostro and his colleagues have studied the orbit of Toutatis more closely than any other known near-Earth object its size.

		The radar images reveal Toutatis to be a "contact binary" asteroid, consisting of two irregularly shaped, cratered objects about 4 and 2.5 kilometers (2.5 and 1.6 miles) in average diameter and rotating with a period between 10 and 11 days.
		Previous radar images taken by Ostro and his colleagues of another Earth-approaching asteroid, 4769 Castalia (1989 PB), were too crude to reveal surface details but did show the object to be bifurcated into two 1-kilometer (0.6 mile) lobes.
		While there are no plans yet to rendezvous with Toutatis, Ostro said it and dozens of other near-Earth asteroids are leading candidates for robotic flyby, rendezvous and sample- return missions because of the asteroids' small gravitational fields and because of the ease of maneuvering spacecraft between the orbits of Earth and the asteroids.

		Tumbling through space like a fumbled football, a peanut-shaped asteroid named 4179 Toutatis is expected to pass within a million miles (1.6 million kilometers) of Earth today.
		Toutatis makes an elliptical four-year trek around the sun that takes it from just inside Earth's orbital path to the asteroid belt between Mars and Jupiter.
		The asteroid rotates around one axis once every 5.4 Earth days and, in turn, rotates around the other axis once every 7.3 Earth days.
