The ExoMars spacecraft’s crash landing might are actually caused by a laptop or computer glitch

Europe and Russia’s ExoMars lander may have suffered a laptop or computer glitch for the duration of its descent to Mars final week, in the end causing it to crash-land to the planet’s surface, Nature reports. Since the lander fell, the mysterious application bug may possibly have triggered the vehicle to feel it had been closer towards the ground than it really was, a lead researcher with the European Space Company suggests. That could be why the entire landing sequence was thrown from whack.
It’s only a hunch, so the true reason behind the crash is not however recognized. But a application error is in the end fantastic news to the ExoMars mission - a joint venture among the European Space Agency and Roscosmos to look for signs of life about the Red Planet. The crashed lander, named Schiaparelli, was genuinely only a demonstration spacecraft, meant to demonstrate that ESA and Roscosmos possess the capability to land heavy objects on Mars. A successful landing would have boosted confidence for your next phase of ExoMars - sending a rover on Mars in 2020. But when a personal computer trouble is usually to blame for Schiaparelli’s demise, that’s a problem that is simpler to fix in advance of 2020 than a hardware difficulty.

Luckily for ESA, it looks like Schiaparelli performed lots of other aspects of its career beautifully. The lander entered the Mars atmosphere exactly on routine and deployed its parachute when it had been supposed to. But above four in addition to a half minutes into the fall, the lander ejected its heat shield and parachute - in excess of half a minute too early. Then the vehicle’s thrusters, meant to slow down the spacecraft even even more, ignited for just 3 seconds when they were supposed to ignite for 30. Offered all these failures - and the new crater that NASA spotted at Schiaparelli’s landing web page - it’s rather most likely that the lander slammed to the Martian surface way too rapidly.
All this seems to recommend a software program error, says Andrea Accomazzo, that is in charge of ESA's solar and planetary missions. Accomazzo thinks possibly Schiaparelli had a problem processing the many facts it was receiving from its sensors. This led the spacecraft to imagine it had been at a reduce altitude than it had been through the fall, leading to a lot of its landing operations to minimize off early
The ExoMars rover might be using the exact same computer software and sensors as Schiaparelli to land on Mars. So if it does flip out to get a computer system glitch, then ESA and Roscosmos can hopefully make the required updates in advance of the rover’s launch in four many years. "If we have now a serious technological issue, then it’s unique," Accomazzo tells Nature. "Then we now have to re-evaluate thoroughly. But I really don't expect it for being the case."

The ExoMars staff hopes to practically re-create Schiaparelli’s landing quickly to check out when they can pinpoint the origin from the failure.
