The Trace Gas Orbiter will release its Schiaparelli lander for a three day coast and a six minute descent to the Martian surface.The lander, which was designed to demonstrate technologies for entry, descent and landing on Mars, is heading for the Meridiani Planum. This is an area that is currently being studied by NASA’s Opportunity rover and Europe’s Mars Express orbiter.
On 19 October, the Schiaparelli lander will be activated a few hours before reaching the Martian atmosphere, when it will be travelling at some 21 000 km/h. The front heatshield – covered with 90 insulating tiles – will be subjected to temperatures of up to 1500 degrees Celsius.
19 October: TGO Mars orbit insertion and Schiaparelli entry, descent and landing on Mars (atmospheric entry expected 15:42 BST / 16:42 CEST, landing 15:48 BST / 16:48 CEST)
20 October: Update on Schiaparelli status; descent images expected
21+ October: Schiaparelli status reports until end of mission
Note: Times shown above are actual event times at Mars; the one-way signal travel time between Earth and Mars is currently just under 10 minutes.
End of planned Schiaparelli transmission. Initial signals were received via the Giant Metrewave Radio Telescope (GMRT) as Schiaparelli descended to the surface of Mars, but no signal indicating touchdown yet. This is not unexpected due to the very faint nature of the signal received at GMRT. A clearer assessment of the situation will come when ESA's Mars Express will have relayed the recording of Schiaparelli's entry, descent and landing.
