Early Wednesday morning--at 4:51 a.m.--Mars will be a mere 34.6 million miles from earth: the closest it's been in 60,000 years. The grandmaster of science fiction, Ray Bradbury, recently said he hopes that one night, 100 years from now, a youngster will stay up late reading his space exploration classic, "The Martian Chronicles," with a flashlight under his blanket--on Mars. We hear a speech from Ray Bradbury, who has also written "Farenheit 451," and more than 500 other published works. He celebrated his 83rd birthday on Friday. The speech was from the Pen Pals Lecture Series sponsored by the Library Foundation of Hennepin County.
