Schiaparelli Lander Did Not Behave as Expected during Mars Descent

ESA’s Schiaparelli mission did not behave as expected as it headed down to the surface of Mars on October 19.

According to telemetry data recovered from the probe during its descent, Schiaparelli’s parachute was jettisoned too early.

The rockets it was supposed to use to bring itself to a standstill just above the ground also appeared to fire for too short a time.

The ESA has not yet conceded that the lander crashed but the mood is not positive.

Experts will continue to analyze the data and they may also try to call out to Schiaparelli in the blind hope that it is actually sitting on the Red Planet intact.

In addition, the Americans will use one of their satellites at Mars to image the targeted landing zone to see if they can detect any hardware. Although, the chances are slim because the probe is small.

For the moment, all ESA has to work with is the relatively large volume of engineering data Schiaparelli managed to transmit back to the “mothership” that dropped it off at Mars – the Trace Gas Orbiter.

This shows that everything was fine as the probe entered the atmosphere.

Schiaparelli’s heatshield appeared to do the job of slowing the craft, and the parachute opened as expected to further decelerate the robot.

But it is at the end of the parachute phase that the data indicates unusual behavior.
