Pioneer 12, which had been orbiting the planet Venus, was directed, by controllers at NASA's Ames Research Center, Mountain View, California, to begin tracking the newly discovered Comet Wilson. This would be the fourth time that Pioneer 2, orbiting Venus since 1986, interrupted observations of the planet to study a comet passing Venus on its way to the Sun. (LA Times, Mar 15/87)
