	2001 News Releases - Deep Space 1 Comet Flyby
		Deep Space 1's risky encounter with comet Borrelly has gone extremely well as the aging spacecraft successfully passed within 2,200 kilometers (about 1,400 miles) of the comet at 22:30 Universal Time (3:30 p.m.
		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 was launched in October 1998 as part of NASA's New Millennium Program, which is managed by JPL for NASA's Office of Space Science, Washington, D.C. The California Institute of Technology manages JPL for NASA.

	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.

	Comet Borrelly or Bust
		Deep Space 1 could become just the second spacecraft to study a comet from a distance less than 2000 km; the first was the European Space Agency's Giotto mission that flew by Halley's comet in 1986.
		Deep Space 1 was hundreds of millions of kilometers away, so like the fabled engineers of Apollo 13, DS1 specialists couldn't tinker with the spacecraft's hardware.
		Deep Space 1 is managed for NASA's Office of Space Science by the Jet Propulsion Laboratory, a division of the California Institute of Technology.

	Deep Space-1
		Deep Space 1 has also tested the feasibility of compressing mission preparation periods to as short as 39 months from initial concept through launch and of reducing mission budgets to substantially less than that of other recent NASA missions.
		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.

	Motorola Keeps Deep Space 1 In Contact
		Deep Space 1 is designed to validate 12 new technologies for scientific space missions of the next century.
		The Deep Space 1 spacecraft is carrying Motorola's newest technology in tracking, telemetry, and control (TT&C) transponders, the Small Deep Space Transponder (SDST).
		This transponder is a major technological leap over Motorola's previous generation of X-Band TT&C deep space transponders, which were used to transmit all the data and images to and from the Earth for the Near Earth Asteroid Rendezvous (NEAR), Mars Pathfinder, and Cassini-Huygens missions.

	General Interest ( DS1
		Science fiction and space enthusiasts as well as space scientists have long dreamed of having routine access to space, a ready supply of probes to greet unexpected and enticing visitors to our neighborhood (such as comet Hale-Bopp), and smart robots investigating the universe.
		Space science missions have made many astonishing and impressive discoveries, but often at great expense.
		By taking risk with missions such as Deep Space 1, NASA is preparing for the time when humankind's robotic (and, eventually, human) emissaries to space are routinely reporting back inspiring discoveries from throughout the solar system and beyond.

		NASA's Deep Space 1 robotic probe, which has already completed all of its mission goals by proving a dozen futuristic technologies, will attempt to tackle one last task later this week in a dramatic pass through a cloud of dust and gas surrounding a comet.
		Deep Space 1 will endeavor to plunge into the comet's coma, a shroud of material that has long kept comets innermost secrets hidden from the view of telescopes.
		Deep Space 1's camera was supposed to take pictures of that asteroid upon approach, then use the new images to make its own navigational decisions in order to get even closer and snap more pictures.

	Spaceflight Now \| Breaking News \| Deep Space 1 returns stunning images of comet
		The preliminary analysis of images and other data returned by Deep Space 1 (DS1) during its recent flyby of comet Borrelly, released at a press conference Tuesday afternoon, show that the comet has a bowling pin-shaped nucleus with an unusual jet of gas and dust emanating from one region of it.
		Mission scientists also found that a large bright area in the middle of the nucleus, as well as a smaller bright region at the small end of the nucleus, are linked to several distinct jets of gas and dust emanating from the nucleus.
		DS1 showed that flying close to the nucleus of a comet might not be risky as once thought.

	The Continuing Adventures of Deep Space 1
		Deep Space 1 spent nearly a year trying out its uncertain technologies and, improbably, they all worked -- many beyond expectations.
		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.

		The challenge in electric space propulsion is to charge a fluid so its atoms can be expelled in one direction, and thus propel the spacecraft in the other direction.
		Deep Space 1, outfitted with BMDO's solar array and the NSTAR ion propulsion system was a success, with both working exactly as planned.

	Deep Space 1 Ready To Catch A Comet Flash
		As DS1 plunges into the coma, PEPE and the diagnostic sensors need only to be pointed in the general direction that scientists specify in order to make their measurements, but MICAS needs to be pointed quite accurately, just as looking through a telescope requires careful aiming.
		According to sources in an unnamed globular cluster where the documentary was previewed, it is a chance to see some of the faces behind the great successes of Deep Space 1 as well as to learn a bit about a few of the exotic technologies that were tested on this incredible mission.
