I'm guessing "bust"

They must be feeding Tierney some good weed up there in the Arctic Circle. He is with a group of people who apparently go there to pretend that they are Mars explorers.

In one afternoon we covered more ground than either of NASA's Rover robots has traveled in two years.

Yeah, we kicked those robots' asses!

Artificial gravity could be created during the flight to Mars by twirling the ship.

Such a ship was designed during the 1990's by Robert Zubrin, the president of the Mars Society ...

Tierney and Zubrin are apparently pretending here that they never read or saw "2001: A Space Odyssey."

Mars, bitches!
