The European Space Agency (ESA) still don’t know what has happened with the module, Schiaparelli, you lost the signal shortly before it hit the surface of Mars. The director of flight operations of ESA, Paolo Ferri, said that both the radio telescope in Pune (India) as on the satellite Mars Express, the signal was lost at the same time.
it Is possible that Schiaparelli has been lost but also that the ESA may try to re-establish communication, ” said Ferri. In the next few hours, the agency will receive in its operations control center telemetry data that it has sent the Orbiter of Trace Gases, already orbiting Mars, to be analyzed.
THAT will morning more information of what has happened with the lander. Yes, the agency believes that it is possible that Schiaparelli started the descent, has been taken off the parachute and after it has separated from the frontal shield and parachute, but it is not clear if it has crashed against the surface or if it managed to land.
Phase prior to the landing. The Orbiter of Trace Gases was inserted today with success in an orbit around Mars. This was one of the previous steps so that the module Schiaparelli in the planet’s atmosphere.
the function of The Orbiter was to record the landing. THAT received the confirmation, through your station in Canberra, that the start of this complex maneuver, which required a change of trajectory for not colisionara with Mars, was produced well, and that the Orbiter had reached its destination. The function of the Orbiter was to record the sequence of entry, descent and landing on Mars of the module, Schiaparelli, whose entry into the atmosphere of Mars was predicted for the 9.42 am (peruvian time). The orbiter will also analyze the Martian atmosphere, particularly the methane gas, but also elements such as water vapor, or oxides of nitrogen.
Goal. Schiaparelli, who split the Sunday of the Orbiter of Trace Gases at a distance of 900 thousand kilometers of the Red Planet, and after having traveled together since march in the mission, ExoMars, is a project of the European Space Agency (ESA) and russia’s Roscosmos that aims to check if there are and/or came to have life of bacterial type in the past on Mars, which in their origin had similar conditions to Earth and favorable to life. But Schiaparelli had a fundamental role, which was to demonstrate new technologies european descent, and landing, in particular the control of the orientation and speed in contact with the surface.
Above.
Schiaparelli will enter the atmosphere at a speed of about 21 thousand kilometers per hour (km/h), which will be braking with a heat shield, aerodynamic, which is more coarse if the input occurs in the middle of a sand storm. Three minutes of having started the descent, when the speed of Schiaparelli has been braking up to 1650 km/h and is 11 kilometers above the surface of Mars, it will deploy a parachute supersonic of 12 meters of diameter and systems guidance, navigation and control, as well as a structure deformable to the earth, according to ESA.
At four minutes after initiating the descent, at an altitude of 72 miles and a speed of 320 km/h, is separated from the frontal shield and turn on the radar. Five minutes later, approximately 1.2 miles of the surface and at a speed of 240 km/h, will release the parachute. Subsequently will trigger a helix of ignition and it will continue to decline until the landing, planned for 14.48 hours GMT.
What will you do after reaching the surface? will Land in an area near the equator of Mars known as Meridian Planum, and you get, for example, the first measurements of the electromagnetic field on the surface of Mars and of the concentration of atmospheric dust. Once on the surface of Mars, Schiaparelli will be able to work between two and eight suns, name as known to the days of mars (a martian day is 24 hours and 37 minutes), depending on the duration of the batteries.
