NASA Explorer Schools was joined by Dr. Timothy Livengood for a special NASA Explorer Schools video chat, "The Reason for the Seasons," at 1 p.m. EDT on June 21, 2011. That's the summer solstice and the first day of summer in the northern hemisphere. If you have ever wondered what causes the seasons on Earth or if other planets have seasons, the video chat was the place to have those questions answered. A recording or transcript of the video chat will be made available at a later time.
Livengood studies planetary atmospheric chemistry and dynamics in the Planetary Systems Laboratory at NASA's Goddard Space Flight Center in Greenbelt, Md. He has led numerous investigations at the NASA Infrared Telescope Facility, including studies of winds and seasonal behavior on Saturn.
Being a scientist doesn't take up all of his time. Livengood has several hobbies. He enjoys reading, bicycling, woodworking, photography and writing lyrics for astronomy comedy music videos. He is also a regular storyteller at the Washington Folk Festival and in the local Voices in the Glen. He recently began teaching a small storytelling class for 8th- and 9th-graders.
Livengood became interested in space exploration watching the Apollo missions when he was a young boy. The Apollo 11 mission especially stands out in his mind, but you'll have to join us to find out why!
