CAMBRIDGE, Mass., (AP) Scientists say Russia's Sputnik II with its dead dog is expected to burst apart when it plunges from outer space, perhaps Saturday.
The scientists at Smithsonian Astrophysical Observatory said last night the burst, if it occurs, will be caused by the air tanks that kept the dog passenger alive for some time after the satellite was launched last Nov. 3.
If the final plunge is at night, they said, the satellite will look like a flaming meteor. In the daytime it might leave a plume of smoke like a high-flying jet.
Dr. John Hynek said that even if only part of the original air pressure remains in the tanks, it still would be much greater than the surrounding atmosphere when the rocket starts to heat up about 50 miles above the earth.
The Smithsonian said Northern United States and parts of Canada might get a last look tonight at the dog-satellite. It listed one passage from Alaska to British Columbia visible to residents of the Northwest, 9:18 PST.

Russia's Sputnik II satellite, with its dead dog passenger kept alive initially by air tanks after launch on Nov. 3, is expected to disintegrate upon re-entry, possibly Saturday, due to pressurized tanks. It may resemble a flaming meteor at night or a daytime smoke plume. Visible tonight over northern US and Canada.
