Sixtieth anniversary of first lunar "probe"
The very first "probe" on the surface of Earth's moon Luna happened
when researchers of the Engineering Laboratories, U.S. Army Signals
Corps, established the first radio link with the Moon by bouncing radar
signals off the lunar surface on January 10, 1946, sixty years ago.
