"On the Record" host Greta Van Susteren will host "Apollo 11: One Small Step to Our Future" on FOX News Channel.

This hour-long exclusive FOX News documentary commemorates the 40th anniversary of Apollo 11’s landing and man’s first steps on the moon. Greta interviews Col. Buzz Aldrin, the second man to walk on the moon, about that mission and about his vision for the future of space exploration.

The special also looks at what it took for America to beat the Russians to the moon following President Kennedy’s famous challenge to go to the moon and return safely within a decade.

Aldrin tells Greta that going back to the moon is a "dead end" for America -- our goal should be Mars; that's the only way to inspire people. Aldrin and our other guests the space program’s most important benefit is "inspiration." That’s what led to over 1,500 "spinoffs" from the technological innovations of the Apollo-era that contribute to improving national security, the economy, productivity and lifestyle. It is almost impossible to find an area of everyday life that has not been improved by these spinoffs.

But, America does have a plan to return to the moon. NASA managers describe the rockets and the crew exploration vehicle for the Constellation Program. This plan is also currently under review by the Obama administration -- due to cost, it may be delayed and redesigned.

Others in this FNC special include: Capt. Jim Lovell of Apollo 8 and 13, Rusty Schweickart of Apollo 9, Capt Gene Cernan of Apollo 10 and 17, Alan Bean of Apollo 12, Jack Schmitt of Apollo 17 and Gene Kranz the Mission Control’s Apollo Flight Director.
