Space Videos Of The Day: Watery Mars, A Mustachioed Astronaut And The Pale Blue Dot

We're all familiar with the image of Mars as a frozen, barren wasteland (in fact, we posted a video showing just that last month). Here's a very different look at the red planet, courtesy of the NASA Goddard Conceptual Image Lab:

Four billion years ago, according to researchers at NASA, Mars may have had a thick atmosphere and vast oceans of liquid water. The video starts with a flyover of a Martian lake that might have been, before soaring across mountains and streams. It ends with a shot of MAVEN, a NASA spacecraft launching later this month that's set to investigate just how Mars lost its atmosphere.

In other space news, everyone's favourite mustachioed astronaut Chris Hadfield released a charmingly goofy video yesterday throwing his support behind the Movember campaign. Check it out:

On the program tonight, we're replaying George's conversation with Commander Hadfield. Make sure to tune in at 7 p.m. on November 14 on CBC TV.

Finally, we present "The Pale Blue Dot," the latest video in The Sagan Series, which uses inspiring speeches from the late American astronomer Carl Sagan to help promote science literacy. The blue dot in question? Earth, of course. As Sagan put it: "That's here. That's home. That's us. On it, everyone you love. Everyone you know.... Every saint and sinner in the history of our species lived there, on the mote of dust, suspended in a sunbeam."

Sagan died in 1996 of complications stemming from myelodysplasia, a blood disease. Last Saturday, November 9, would have been his 79th birthday.
