"I will darken the earth in the clear day" AMOS 8:, V IEW FROM A NASA SATELLITE, poised in synchron ous earth orbit 2 2,300 miles over Quito, Ecuador, offers the first look from space at an entire eclipse shadow, the dark umbra surrounded by the fuzzy, lighter penumbra. Like an ink stain on the earth's bright face, the moonshade shrouds Newfoundland just before slipping off into space. The United States and Mexico, with Baja California clearly visible at left center, lie partly covered by!clouds. Whimsical sketch (right) by Dr. Menzel, well-known among academic colleagues for his scientific doodles, depicts the path of totality. Drawn with a toothy grin, Comet Bennett, visible during March, watches the scene. Point of the conical umbra touches earth about every 18 months on the average and most often on oceans or inaccessible land. Streaking 8,500 miles in three hours, this shadow skimmed the populous East ern Seaboard. It was the last total eclipse the eastern United States will see in this century.
