the ROME - THE LANDER Schiaparelli of the ExoMars mission is fallen on the soil of Mars. Its retrorazzi have only worked for three seconds, then the on-board computer has them turned off. The said Paolo Ferri, director of flight operations of the missions of the European Space Agency (Esa).
“The data that we have – said Needle, they say that the landing sequence has worked up to the posting of the screen to the rear of the parachute. the power of the retrorazzi has worked only for three seconds, then the on-board computer has decided to turn them off”. At that point, Schiaparelli has found himself with the rockets turned off and the “let’ s assume that the lander is simply just fell off”.
Battiston, “the Mission failed for the data”. “For the quantity and quality of data that We are receiving from Exomars is a mission accomplished. Europe has its own satellite in the orbit of Mars”. This was stated by the president of the Italian space Agency Roberto Battiston. “The Trace gas orbiter is perfectly in orbit and operational, and therefore able to monitor and send data on the composition of the martian atmosphere; the lander Schiaparelli, that was a test, apparently, has executed all the maneuvers provided up to a few seconds from the contact with the ground, such as the opening of the parachute, the decoupling of the heat shield and the firing of rockets braking – continues Battiston. We lack the data on the last seconds over which the engineers are working on it. Overall, we are encouraged to continue the work for exomars and 2020, one of the main topics of the ministerial”.
The reconstruction of the Esa. But for the Esa and Thales alenia space, the company that built the probes, however, it’s still all to verify. The european space Agency remains cautious about the fate of the form, which, after having dropped by the probe to the euro-Russian Exomars, it would have had to “ammartare” on the evening of October 19, 2016. The signal with Schiaparelli was lost a minute before the contact with the ground.
It’s Been confirmed – you know the Esa – that the propellers were activated briefly, however, it seems likely that you are turned off earlier than expected, at an altitude that has yet to be determined.
The data were partially analyzed and confirm that the phases of the entry and descent were held as planned, with events diverging from what is expected after the ejection of the heat shield and the rear of the parachute. The expulsion itself seems to have occurred earlier than expected, but the analysis is not yet complete.
essential data that Schiaparelli sent to the probe mother Tgo during the descent have been downloaded and are currently the experts are analyzing. The first indications from the signals captured by the Giant metrewave radio telescope (Gmrt), an experimental line of telescopes located in Pune, India, and from orbit by Mars express of the Esa, suggest that the module has successfully completed most of the stages in his descent of 6 minutes through the martian atmosphere. These included, for example, the deceleration through the atmosphere, and the opening of the parachute and the heat shield.
But the signals recorded from the railway station of Pune and from Mars express are stopped immediately before the module touched the surface as expected. Discrepancies between the two sets of data are the analysis of the experiments at the Centre of Esa’s space operations in Darmstadt, Germany.
The detailed telemetry recorded by the trace gas orbiter was needed to better understand the situation. At the same time that Schiaparelli approached the descent, the orbiter performed a maneuver crucial to the insertion in orbit – the ‘Mars orbit insertion’ – completed successfully.
“For what, hope is always the last to die, there is hope limited to be affected by the lander Schiaparelli,” he says from Paris, the spokesperson of the Esa, Franco Bonacina. Regarding the possibility that the lander Schiaparelli may have crashed on Mars, Bonacina adds: “it is Difficult to say at the time that it was a ‘crash’, mission scientists are studying a huge quantity of data and analysis are in progress.”
“the team of The tool, Amelia,” which is located at the edge of the lander, Schiaparelli believes that the majority of the data has been collected”, he wrote in a tweet on Esa Operation Dan McCoy, project manager of the ExoMars mission.
“For the quantity and quality of data that we are receiving Exomars is a mission accomplished. Europe has its own satellite in the orbit of Mars,” says the president of the Italian space Agency Roberto Battiston. “The Trace gas orbiter is perfectly in orbit and operational, and therefore able to monitor and send data on the composition of the martian atmosphere; the lander Schiaparelli, that was a test, apparently, has executed all the maneuvers provided up to a few seconds from the contact with the ground, such as the opening of the parachute, the decoupling of the heat shield and the firing of rockets braking – continues Battiston – We lack the data on the last seconds over which the engineers are working on it. Overall, we are encouraged to continue the work for Exomars and 2020, one of the main topics of the ministerial”.
The lander “is entered in the martian atmosphere. The heat shield worked properly. He open the parachute at the correct altitude. Then, the data indicate a behavior not exactly as we expected. But all of the hardware of the lander acted correctly”, he had said Andrea Accomazzo, chief of operations of the planets of the Esa, by responding to the questions on the “debut” of the lander, Schiaparelli, launched yesterday on Mars. Six minutes that have kept Europe in suspense, and operations followed by a night of “silent”, that the engineers of the Darmstadt monitored by analyzing the available data.
“From the engineering point of view these data are exactly what we wanted,” he added Accomazzo said, referring to what was transmitted from the probe for up to 50 seconds before impact on the martian soil. Something abnormal happened, had said to the scientists, after the release of the supersonic parachute and during descent of the probe, which had lost the tracks about a minute before touchdown. A yellow that the Agency has now partially solved by studying the data available: the 600 megabyte collected by the probe Tgo.
“Not a problem of communication”, had clarified the Esa the day after, through the words of Paolo Ferri, head of flight operations of the missions of the European Space Agency, who explained how in any of the further steps that have occurred in the night, the probe Mro (Mars Reconnaissance Orbiter) Nasa has been able to intercept any signal from the lander mission ExoMars.
In any case, he had insisted the number one of the Esa’s ExoMars mission 2016 is to be considered a success because the probe mother, Tgo (Trace Gas Orbiter) entered regularly in the orbit of mars, it is nominal and, therefore, will continue to collect useful data to prepare for the mission 2020 which is expected landing on Mars a rover with a drill, manufacture Italian, that will punch the short martian soil up to 2 metres deep in search of traces of life past or present.
