When's Halley's comet flashes by in 1986, Europe plans to greet it with its own satellite. The satellite will be named "Giotto," after the Florentine painter whose 14 th-century "Adoration of the Magi" includes perhaps the first visual record of the comet.
Giotto's flyby will be sponsored by the ESA, or European Space Agency. It will fly 1 million miles to photograph the comet, measures its magnetic field, and sample the chemical makeup of its vast tail.
The Russians, Japanese, and perhaps Americans are also planning missions. but the Europeans hope to fly closest to the comet -- perhaps only 1,000 kilometers from its head.m
