York, ME (NEWS CENTER)-- Astronaut and York native Chris Cassidy began a series of presentations to schools around Maine today. He visited his Alma Mater, York High School, to talk to the kids about his adventure and the importance of science and mathematics.

Cassidy spent 166 days in space on this, his second mission. He covered 75 million miles and made three space walks.

Two received international coverage. On the first, he helped fix an ammonia leak which could have threatened the existence of the space station. On the second, an Italian astronaut had a problem with a leak in his space suit. Cassidy guided his colleague back to the space station in an effort which could have been life saving.

Cassidy will speak tomorrow at South Portland and Greely high schools. The public is invited to hear him speak at Trinity Episcopal Church in Portland on Wednesday night at 6:30.

People in Bangor are invited to attend the Husson University Community breakfast which begins at 7:30 with Commander Cassidy's remarks taking place at 8:00.
