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.
Observing
See Mars get very close to Neptune at dusk on 7 December
Observers in the British Isles looking due south close to 6pm GMT on Friday, 7 December will find magnitude +0.1 planet Mars about 30 degress, or a span and a half of an outstretched hand at arm’s length, above the horizon. What you won’t see unless you have binoculars or a small telescope is that magnitude +7.9 outermost planet Neptune lies just one-tenth of a degree from the Red Planet.
