Seven U.S. Delta rockets and a French observation satellite   

have exploded in space.   

In 1961, Cuban premier Fidel Castro charged that a chunk of   

a U.S. spacecraft had fallen on Cuba and killed a cow.   

In 1962, a 21-lb. fragment of Soviet Sputnik IV landed at   

the intersection of Park and North 8th Streets in Manitowoc,   

Wisconsin.   

Over 7,000 objects floating in space are being tracked from   

earth; only five percent are satellites.   

Dodging space junk is a dangerous occupation. A 0.5 milli-   

meter metal chip could puncture a space suit and kill an   

astronaut walking in space.   

In 1978, a Soviet satellite came crashing back to Earth,   

contaminating hundreds of square miles of Canadian territory   

with radiation.
