In mid-October, the mission has reached its natural conclusion with the depletion of the propellant

AREA NEWS: - After more than four years of activity avvivicna the end of the beautiful mission of the ESA GOCE satellite (Gravity field and steady-state Ocean Circulation Explorer) mission that we have followed since its BEGINNING and the details of which you can find them in section of the blog at the following URL
In mid-October, the mission has reached its natural conclusion with the depletion of the propellant of the satellite, which from an orbit of 224 km altitude slowly but surely began to lose altitude.
This morning GOCE was at an altitude of about 160 km friction with the dense layers of the atmosphere always pù is causing significant increases in temperature in many parts of the spacecraft.
Of course, the ESA continues to monitor all the activities of re-entry of the satellite how to make nachos supreme (in fact there is an international team that controls the descent). As the hours pass become more and more reliable estimates of location above which debris how to make nachos supreme may fall survived the descent.
When the satellite will fall to below 100 km altitude, the density of the atmosphere will increase dramatically. The speed will be about 25 000 km / h and the pressure more aerodynamic heating will cause the destruction of the vehicle, approximately at an altitude of 80 km, thus generating a great number of debris. The risk to the public is minimal, according to the statement by ESA.
Even in Italy it is monitoring the evolution of the situation, according to ESA. In the last statement that the ASI sent to the monitoring group composed of experts of the National Department of Civil Protection, the SIA itself, the Department of the Fire Department, ENAV, ENAC, ISPRA, the Operational Command Interagency and Friuli Venezia Giulia representing all regions, the time window for the uncontrolled re-entry of the satellite ranges from 22 of today Saturday, November 9 to 13 hours of Monday, 11.
From the press of Civil Defense: "... how to make nachos supreme The windows are of interest for Italy, for now three: from 8:26 to 9:06 on Sunday, November 10, potentially involving the Centre-North (Valle d'Aosta, Piedmont, Liguria , Lombardy, Veneto, Trentino Alto Adige, Emilia-Romagna, Tuscany, Sardinia), from 19:44 to 20:24 every Sunday potentially affecting the territories of Valle d'Aosta, Piedmont, Liguria and Sardinia, from 7:48 to 8:28 on Monday, November 11, period for which no information available yet because they are still ongoing how to make nachos supreme processing of the possible trajectories by ASI ... " . Data source, ESA.
Now .. let's see how it goes .. but these brilliant minds ESA could not use the residual fuel to allow for a controlled re-entry in a safe area? I obbligherei anyone who wanted to put something in orbit, even a pair of slippers, to provide in advance a plan for the safe return, once the orbit would decay .. off on .. it is not meteors .. but of pieces of technology that we have sent to us .. I think to run some, albeit minimal risk, represents a remarkable act of lightness! Really a good test of applied science! : (Reply Delete how to make nachos supreme
Ale, I completely agree with you. A space mission ends with the return to Earth (soft landing or destructive re-entry) and you need to plan a trajectory to return absolutely "safe" Delete
Ale and Sergio have written, anticipating me, exactly what I thought, and I imagine that many people think. You will have to somehow regulate this operation and to oblige manufacturers to design technologies for non-invasive or risky return. Must be imposed by an authority over the parties, a bit like that in the U.S. had imposed on car manufacturers, years ago, a gradual reduction table, how to make nachos supreme year after year, of the pollutants how to make nachos supreme from the exhaust gases.

But how do you persist in leaving how to make nachos supreme the case falls within the maximum cross your fingers and hope it does not happen a disgrace? I do not know, some of you are at least aware of any conversations initiated by scientists, technicians or bureaucrats shift towards a strategy that relies not only on the seats, or the old cliché Italic, according to which the act must first escape us the dead, that is for homo "insipiens" in its entirety?
