Wow!!   They getting into unknown here.
I mean they could find anything.
 
Here's a list to get ya thinking:   
Purgatory   
A large UFO base 
The Ark of the covenant 
Amelia Earhart
A small German town with Adolph Hitler and some Nazi war criminals 
Jesse James' treasure 
The real killer of Nicole Sympson 
The 10 missing tribes of Israel 

Hummm....

Odd this is, the Russians can find funding to drill a deep hole in some ice to see whats living, if anything, in a puddle, what about the short-fall in funding for sealing up Chernobyl ?. As you say, Hummmm  .
