ROFL! Of course, Hoagland being Hoagland, is implying exactly that. He's saying that the Rover was about to transmit something "they" (some kind've shadow government black ops thing) don't want the public to know, namely that there either is, or was, sentient life on Mars. Hoagland believes that ancient Martians were the source of human life on Earth. Further, the shadow government knows that if Christians found out about this, they would freak out and commit homicides, suicides, and general chaos and mayhem en masse.
Folks, if you don't listen to Hoagland on Coast to Coast, you're really missing some great entertainment!!
