ESA Completes Inquiry into ExoMars Schiaparelli Failure

PARIS (ESA PR) — The inquiry into the crash-landing of the ExoMars Schiaparelli module has concluded that conflicting information in the onboard computer caused the descent sequence to end prematurely.

The Schiaparelli entry, descent and landing demonstrator module separated from its mothership, the Trace Gas Orbiter, as planned on 16 October last year, and coasted towards Mars for three days.

Accusations are flying that ESA’s ExoMars Schiaparelli lander crashed into the Red Planet due to poor ground testing conducted by a Romanian company named ARCA Space.

ESA released the preliminary conclusions after the Italian Space Agency had accused that the decisive tests for the Sciaparelli lander simulations had been entrusted to an organization “which hadn’t enough expertize”. It’s about Arca Space Romanian company, based in Las Cruces, USA, as La Repubblica reported.

In retort, the Arca Space Corporation manager, Dumitru Popescu warned the Italian space agency to be more careful, as they don’t have proves to support their accusations. “They could pay the price. We are at ease that we did all we could do: to run a specific test we should have flown very closely to the Russian base in Sevastopol. Russia has just annexed Crimea and we risked generating a conflict between the Russian Federation and NATO,” the Romanian manager argued.

ESA said last week that an inertia measurement unit became saturated with data during descent, providing data that made the lander’s computer believe the vehicle was either about to land or had already landed. The computer ordered the release of the parachute even though the lander was still 3.7 km above the martian surface.

Schiaparelli was designed to test the landing system for a rover that ESA plans to place on the surface. Agency officials have said they gained valuable data from the test.

Arca Space has set up operations in Las Cruces, NM, where it is making hover boards.

DARMSTADT, Germany (ESA PR) — A high-resolution image taken by a NASA Mars orbiter this week reveals further details of the area where the ExoMars Schiaparelli module ended up following its descent on 19 October.

The latest image was taken on 25 October by the high-resolution camera on NASA’s Mars Reconnaissance Orbiter and provides close-ups of new markings on the planet’s surface first found by the spacecraft’s ‘context camera’ last week.

DARMSTADT, Germany, 21 October 2016 (ESA PR) — NASA’s Mars Reconnaissance Orbiter has identified new markings on the surface of the Red Planet that are believed to be related to ESA’s ExoMars Schiaparelli entry, descent and landing technology demonstrator module.

DARMSTADT, Germany, 19 October 2016 (ESA PR) — The Trace Gas Orbiter (TGO) of ESA’s ExoMars 2016 has successfully performed the long 139-minute burn required to be captured by Mars and entered an elliptical orbit around the Red Planet, while contact has not yet been confirmed with the mission’s test lander from the surface.

ExoMars Spacecraft Enters Orbit; Fate of Lander Unknown

ESA has placed its ExoMars Trace Gas Orbiter into orbit around the Red Planet. However, the fate of the Schiaparelli lander lander remains unknown. No signal has been received yet.

18:53 CEST: The ExoMars/TGO spacecraft completed its critical orbit-insertion manoeuvre at Mars today and its signals were received by ground stations at 18:34 CEST, just as expected. The timely re-acquisition indicates the engine burn went as planned, and mission controllers are waiting for a detailed assessment from the flight dynamics specialists at ESOC to confirm it.

Teams monitoring the Schiaparelli lander continue waiting for indication of the lander’s progress. Engineers are waiting for the next signal receipt slot, which will be provided by NASA’s Mars Reconnaissance Orbiter, which will overfly the Schiaparelli landing site between about 18:49 and 19:03 CEST, and downlink any received signals at around 20:00 CEST.

18:35 CEST: ACQUISITION OF SIGNAL from the ExoMars Trace Gas Orbiter after it emerged from behind Mars.

17:28 CEST: The orbit insertion manoeuvre of the ExoMars Trace Gas Orbiter should have ended but the spacecraft is now behind Mars on the line of sight from Earth. Acquisition of signal is expected when TGO emerges from behind Mars after 18:32 CEST.

17:12 CEST: 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.

16:50 CEST: Signals from Mars take 9 minutes 47 seconds to reach Earth today, so the teams are waiting for the first indications that the entry, descent and landing events actually happened at Mars. It may take some hours to get official confirmation that Schiaparelli has landed on the Red Planet. Stay tuned.

DARMSTADT, Germany (ESA PR) — This week, the commands that will govern the Schiaparelli lander’s descent and touchdown on Mars were uploaded to ESA’s ExoMars spacecraft, enroute to the Red Planet.

The Trace Gas Orbiter has been carrying the Schiaparelli entry, descent and landing demonstrator since launch on 14 March. Upon arrival on 19 October, Schiaparelli will test the technology needed for Europe’s 2020 rover to land, while its parent craft brakes into an elliptical orbit around Mars.
