Today marks 40 years since human beings last walked on the moon.  Apollo 17 departed the moon for its return trip to Earth on this day in 1972.  What has become of deep space exploration four decades later?

FOX News Radio's Eben Brown reports:

Humanity's last giant leap...

(Cernan) "We leave as we came, and God willing, as we shall return, with peace and hope for all mankind."

Apollo 17 Commander Gene Cernan leaving the moon's surface.

Now, a return moon mission is cancelled, but Cernan says these missions inspired a generation of national pride.

(Cernan) "How much is that worth?  Is that worth a half a penny of every one of your tax dollars?  I'll let you answer that."

Cernan speaking on a special edition of FOX News Reporting, airing again this Sunday afternoon on the FOX News Channel.
