Professor Mark Sims on the discovery that Beagle 2 made it to the surface

An ultra-sensitive seismometer aboard NASA’s InSight Mars lander finds a huge molten core at the heart of the red planet.

Mars hasn’t always looked like it does today. Some 3 to 3.5 billion years ago, the planet underwent a huge tilt of 20 to 25 degrees. The gigantic Tharsis volcanic dome, which started to form over 3.7 billion years ago, grew so massive that it caused Mars’ crust and mantle to swivel around, shifting the Tharsis dome to the planet’s equator.

The Mars 2020 rover continues to take shape at the Jet Propulsion Laboratory with attachment of its robot arm and SuperCam instrument.
