This week marks the 50th anniversary of John Glenn's historic orbit of Earth.  In 1962 Glenn, onboard the Friendship 7 craft, became the first American to enter orbit.  He circled the planet three times in less than five hours.  This achievement, through the Mercury Program, paved the way for America's successful space program; eventually reaching the moon and building the International Space Station.

To celebrate the occasion, Senator John Glenn spoke with astronauts aboard the International Space Station via video link.  This event was hosted by NASA's Future Forum at The Ohio State University located at Columbus Ohio.
