Those who remember John Glenn's trip into space in 1962 will have a familiar voice to guide them when the Ohio senator returns to space in October.

Walter Cronkite will be in the studio to help cover the event in a reunion of sorts. Cronkite was in the anchor's chair for CBS when Glenn became the first American to orbit the Earth 36 years ago.Cronkite, 81, will join CNN reporter John Holliman at Kennedy Space Center on Oct. 29 as the 77-year-old Glenn, one of the seven original Mercury astronauts, begins a nine-day mission aboard the space shuttle.

"I'm thrilled at the opportunity to be live again," Cronkite said. "It will carry me back about as far as it carries Glenn back."

Cronkite, who retired as CBS anchor in 1981, covered the manned space program from its 1961 inception.

"John Glenn and I are old friends," Cronkite said. "I told him if they wanted to test an older guy in space, I ought to go. Or I could go with him, play canasta up there."
