Halley's Comet: The Encounter

1986-03-13

Tonight's news from the comet comes as Europe's Giotto spacecraft plunges deep into the glowing dust and gases of its coma. At 47 miles per second, every grain of dust strikes like a bullet. Will Giotto be destroyed by that deadly hail, or will it win through, to send back the first pictures of the mysterious object at the heart of Halley's Comet? Horizon and The Sky at Night join forces, with Patrick Moore reporting from mission control at Darmstadt in West Germany, and James Burke at Greenwich, where Edmond Halley was Britain's second Astronomer Royal.
