Mars lander crashed at 540km/h after altitude misjudgement
A computer glitch on Europe's Schiaparelli Mars lander miscalculated the spacecraft's altitude, causing it to crash into the red planet's surface at a speed of 540 kmph on October 19, according to the European Space Agency (ESA). The computer had judged that the lander had reached the Martian surface when it was actually 3.7 km above the surface, ESA added.
