	Deep Space 1
		Deep Space 1 was successfully launched from pad 17-A at the Cape Canaveral Air Station at 12:08 UT (8:08 a.m.
		DS1 was originally scheduled to fly by the asteroid 3352 McAuliffe in 1999 and comet P/West-Kohoutek-Ikemura and the planet Mars in the year 2000 but because of a launch delay these targets were no longer possible.
		DS1 was to fly by the near-Earth asteroid 1992 KD on 28 July 1999 at a distance of 5 to 10 km.

	Deep Space-1
		Deep Space 1 began taking its fl-and-white images of the comet 32 minutes before the spacecraft's closest pass to the comet, and the best picture of comet Borrelly was taken just a few minutes before closest approach, as the team had planned.
		Deep Space 1 is designed to test and validate the use of such propulsion in deep space for the first time, so the ongoing diagnosis of Tuesday's behavior is in keeping with the mission's goals.
		Deep Space 1 may then be on a trajectory resulting in the flyby in January 2001 of the dormant comet Wilson-Harrington that is in the process of changing from a comet to an asteroid.

	The Continuing Adventures of Deep Space 1
		Rayman continued: "When we were firing the ion engine during tests in 1998 and 1999 we always steered to keep our options open for an encounter." Their favorite target was 19P/Borrelly, an intriguing comet that had veered toward the Sun during the 19th century when it passed too close to Jupiter.
		By visiting Borrelly, Deep Space 1 could examine a second comet at close range, perhaps as near as 2000 km, and provide valuable intelligence to comet mission planners.
		NASA's Deep Space 1 probe is now underway for an encounter with comet Borrelly after a thrilling rescue of the spacecraft by JPL engineers.

	Deep Space 1
		DS 1, the first mission in NASA's New Millennium program, is powered by an ion engine known as NSTAR, a type of xenon-ion propulsion system.
		Similar systems have been used for station-keeping by some satellites for a number of years, but the DS 1 ion drive is larger, more efficient, and has worked longer than any previously flown.
		It proved a valuable fix: on Sep. 22, 2001, DS 1 flew past Borrelly's nucleus at a distance of only 2,200 km, snapping 30 or so superb fl and white photos and collecting data on gases and dust around the comet.

	Exploring Mars - Deep Space 1
		A major step in the plan for a manned landing on Mars was realized on October 24, 1998, when NASA's Jet Propulsion Laboratory successfully launched Deep Space 1, a technology-validation test vehicle with the primary goal of confirming and refining first-ever, operational ion-propulsion technology.
		As of May 1, seven of DS-1's payload of 12 experimental/confirmation technologies had accomplished 100% of their basic testing procedures with the others on schedule and having completed 75% of the experiments.
		Deep Space 1 is now more than twice as far from Earth as is the Sun, more than 315 million kilometers (195 million miles) from Earth, so far away that the time to complete two-way radio communication, that is, to send a command and receive an acknowlegement, is more than half an hour.
