A software bug is causing the crash probe Schiaparelli

Yet say what exactly the cause of the crash a research probe on Mars is difficult, data is very little, but some experimental developments in this direction already. Scientists believe that a fatal mistake could be a software glitch.
Researchers from the European space Agency believe that computer error is the cause of the accident probe Schiaparelli, if the software worked as expected, the device without any problems was about to land on Mars.
Now, scientists must isolate and correct the error, so it is not repeated when the next mission in 2020-th year, when it will be send to the Red planet is much more bigger and complex terrain. Last week NASA released a sad picture which shows the crash of the European probe, the probe obviously had time to release the parachute, but apparently too late.
Unlike the previous failed mission 3 of Beagle 2003-year, Schiaparelli managed to pass some information on the orbital repeater Ц Trace Gas Orbiter during descent. How to write colleagues from Nature News, this information is visible cascade of software errors that cause not successful landing.
The descent starts well Ц Schiaparelli smoothly goes into the atmosphere, opens a parachute. Everything goes wrong from about the fifth minute of the planned six minutes till landing.
Still it remains a mystery why the machine throws heat shield and parachute n one minute sooner than necessary. Then Schiaparelli worked the engines for a short three seconds (a procedure which in principle should last 30 seconds). It turned out in fact that the engine is started when the probe was a few meters from the surface of Mars.
It turns out that the onboard computer thought that is in the vicinity of the planet and used all of this procedure. Probe even shot off a few sensors that had to study weather conditions and electric Polyana Mars after landing. All would have been true if the computer has not made a fatal error.
When scientists find a real error and it turns out that this is a software bug, not hardware, Troubleshooting will be much more straightforward.

Do you believe that life on Earth originated from space Do you believe that life on Earth originated from space Scientists are studying the emergence of life on the planet is not the first century and as it turns out, each time more and more interesting things can be found. Panspermia is not fiction, but more than reality, more and more scholars inclined to the idea of the origin of life on earth exactly in this cosmic way. Recently, even American scientists From the research center of Ames NASA have revealed a new fact confirming this hypothesis. The probability that life came to Earth from deep space on an asteroid is very high. If life itself to us on the planet was not able to fly in a li...

On December 22  2018  the Earth was lucky  but will it be lucky next time  Flew past the asteroid 2003 SD220 On December 22 2018 the Earth was lucky but will it be lucky next time Flew past the asteroid 2003 SD220 Past the Earth while at a respectful distance fly asteroids, they fly quite a lot and they are sometimes very large, but while they fly past we live and sleep peacefully, but when they collide with the Earth it will probably be the last thing that humanity will see. Recently, astronomers in the near space found the asteroid 2003 SD220, it flew so close that it was even able to probe the radar and there are even unique images in the network. With the help of radar it was possible to consider even the configuration of the object, its spin of rotation and it was already possible to mor...
