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.

See Venus lap Jupiter, then Mars, in an early morning planetary race
In the remaining days of October and early into November, a fascinating series of planetary peregrinations plays out low in the East before dawn twilight gets too bright. Venus, like a sprinter on the inside lane of a running track, overtakes both Jupiter in Mars in two readily observable conjunctions set against the stellar backdrop of constellations Leo and Virgo.
