April 21, 2008 at 12:00pm ET, Richard Garriott, private space explorer and son of NASA Skylab Astronaut Owen Garriott, will hold an interactive live webcast with students and teachers discussing his upcoming flight to the International Space Station (ISS), scheduled for October 2008. All students are invited to submit video or written questions about astronaut training or living and working in space. We strongly encourage students to participate as we take a new and creative approach with this webcast, by asking students to submit videos to be posted on the Challenger Center YouTube site. Students can submit their question on Challenger Center for Space Science Education's website: www.challenger.org. Deadline for submissions is April 18th.

Students questions selected will be answered by Mr. Garriott during our live webcast. Video submissions will be posted on the Challenger Center YouTube site for students, educators and the general public to view. All Challenger Center webcasts are free and open to the general public and archived for post event viewing.

As the next civilian to fly into space, Richard plans to engage with students, teachers and the 50 Challenger Learning Centers around the world through interactive activities before, during and after his flight to the International Space Station, currently scheduled for October 2008.

Challenger Center for Space Science Education was founded in 1986 by the families of the astronauts lost during the last flight of the Challenger Space Shuttle 51-L mission. Through Challenger Center's programs and our network of 50 Challenger Learning Centers, the diversity, spirit and commitment to education that exemplified the Challenger 51-L mission continues to make an impact on students, teachers and families. Today, the crews mission continues with over 300,000 students and 25,000 teachers a year engaged in science, mathematics, engineering and technology.
