NASA engineers hope to send a robot snake to explore Saturn's icy moon Enceladus

Bob McDonald's blog: Nature-inspired robots could help us get around and into extreme icy terrains to explore subsurface moon oceans.

Future fate of the Earth seen as planet is engulfed by its parent star

Bob McDonald's blog: Humanity gets its first glimpse of what happens when an aging star overwhelms a close orbiting planet, just as our sun is expected to eventually do with Mercury, Venus and Earth.

Bob McDonald's blog: Canada's role in space has been largely silent for six decades since the development of the Avro Arrow, and when we launched our first satellite. But we've been there for the whole ride.

Some planets could support life in a narrow twilight zone, study suggests

Bob McDonald's blog: Scientists used climate models to show how planets around other stars with extreme environments could have a relatively benign twilight zone — which could mean a higher chance of life existing on these planets.
