A realtime animation of the European Space Agency’s ExoMars Schiaparelli module entering and descending through the atmosphere to land on Mars. The animation starts when the lander enters the atmosphere at an altitude of 121 km at 14:42 GMT. In six minutes it will use a heatshield, parachute and thrusters to brake from 21,000 km/h to a near standstill 2 metres above the surface, where a crushable structure on its underside will absorb the final shock.

Scientists predict that rocky planets formed from ‘pebbles’
Using a new process in planetary formation modelling, where planets grow from tiny bodies called “pebbles,” Southwest Research Institute scientists can explain why Mars is so much smaller than Earth. This same process also explains the rapid formation of the gas giants Jupiter and Saturn, as reported earlier this year.

NASA confirms evidence that liquid water flows on today’s Mars
New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious darkish streaks that appear to ebb and flow over time are seen on the Red Planet.
