Actor Colm Feore's Something You Might Not Know About Canada segment involved comparing the planet Mars to Gros Morne National Park in Newfoundland.
"There's a rust-orange area in Gros Morne called the Tablelands, which has been a great place for researchers to learn about signs of life on the red planet," said Feore.
"The rocks in the Tablelands have a similar mineral composition to the rocks on Mars. All the Mars goodness without any of the pesky travel."
