In this program, recorded before the recent impact of the comet Shoemaker-Levy 9 with the planet Jupiter, Eugene Shoemaker of the Lowell observatory and Dr. Torrence Johnson of NASA's Jet Propulsion Laboratory, discuss how celestial collisions have affected the history of the solar system.

Sixty-five million years ago, scientists believe, an asteroid smashed into the earth, ending the reign of the dinosaurs. Disastrous as it was, scientists have nevertheless found it difficult to explain how the asteroid impact could have killed plant and animal life on the other side of the planet. Kevin Baines of the Jet Propulsion Laboratory believes he may have found the answer in Mexico's Yucatan peninsula.

Hubble program scientist Ed Weiler reports on the search for missing matter in the universe. One theory held that the missing mass was in the form of red dwarf stars; but when Hubble searched for these red dwarf stars it found nothing, and the mystery remains unsolved.

Who on Earth today has looked out at the stars and failed to wonder if anyone was looking back? Richard Terrile of NASA's Jet Propulsion Laboratories tells how the Astronomical Studies for Extra-Solar Planetary Systems, or ASEPS, is searching for planetary systems. Instead of sending out spacecraft to visit nearby stars, scientists are observing the stars' behaviour and analysing the light they send to Earth. A slight 'wobble' in the star's rotation indicates the possibility of a planetary system.

It's called the New Millennium Initiative -- a revolutionary new way to build spacecraft for the 21st century. Mary Kicza is with NASA's Office of Space Science. "We're preparing to launch smaller spacecraft on the order of 250 kilograms. New Millennium is going to push that even further still and get to the 50 kilogram and hopefully into the tens of kilograms" range for spacecraft.

Every fifteen years, something strange happens to Saturn's rings. They disappear for a few minutes when they turn edge toward us. It happened again in May 1995, and repeated twice more in the same year. The event gave astronomers a unique opportunity to study the rings and hunt for tiny moons, and helped scientists plan NASA's upcoming mission to Saturn, which will visit the ringed planet in 2004. Linda Horn, mission scientist of the Jet Propulsion Laboratory, talks about the mission in this final episode of Space Stories, production of which has been discontinued by NASA.

Since the launching of NASA's powerful Hubble Space Telescope the universe at large is now being studied in ever greater detail. Questions about the surrounding universe are being answered, only to reveal even more questions to be pursued by new generations of space scientists. Astronomer Vera Rubin of the Carnegie Institution of Washington, D.C., puts today's exploration of the universe in perspective.

In 1996, the United States and Russia sent spacecraft to the planet Mars. One of those probes was called 'Mars Pathfinder'. It deposited a micro-rover on that far away world. Donna Shirley was manager of the Mars exploration program office at NASA's Jet Propulsion Laboratory. "Its about as smart as a bug," she says, describing the micro-rover's onboard hazard detection system.

The spacecraft Ulysses has set out on its long voyage to study the sun. Miriam Rorman of NASA headquarters explains how important it is to look at the sun from all angles, not just from the plane of the ecliptic as visible from earth. "Climate is driven by the sun," she says, and adds that an important aspect of the Ulysses project is to examine the sun during the upcoming solar activity maximum.
