Valentina Tereshkova is a retired Soviet cosmonaut, and was the first woman to venture into space. She was selected out of more than four hundred applicants, and then out of five finalists, to pilot Vostok 6 on the  June 16^th , 1963, becoming both the first woman and the first civilian to fly in space, as she was only honorarily inducted into the USSR's Air Force as a condition on joining the Cosmonaut Corps.

NOVA - Meteor Strike

Today on Discovery Enterprise we present an exciting episode of the acclaimed PBS documentary series NOVA titled Meteor Strike concerning the Chelyabinsk Event, when a 10,000 metric ton exploded over the Russian city of Chelyabinsk with thirty times the explosive yield of the atomic bomb that exploded over the Japanese city of Hiroshima on August 6^th, 1945.

This event highlights the urgent need to establish a planetary defense system to protect the Earth from future potentially deadly impact events.

A potential disaster scenario where a sizable asteroid or meteorite explodes over or impacts a major urban center can no longer be treated as mere science fiction fancy. It happened last February when over 1,000 people were actually injured. And, it will one day happen again.
