[QUOTE="skomedal, post: 861782, member: 280388"] Latest update from esa:- [B]10 November 2013[/B] Less than one day before the predicted reentry into the atmosphere, [URL='http://blogs.esa.int/rocketscience/2013/11/10/sunday-mornign-update-from-esoc/']the spacecraft is still functioning well and standard spacecraft operations activities are proceeding.[/URL] The satellite is at an altitude of about 147 km, dropping at a rate of more than 1 km an hour. Drag levels are now too high to be measured by the accelerometers. Based on the results of the orbit determination, average drag levels are at about 165 mN (milli Newton). Temperatures of units and subsystems close to the front of the spacecraft continue to increase, but have not yet reached levels threatening the correct functioning of GOCE. The orientation of the spacecraft is as it should be, with the attitude control system continuing to work well. Owing to its aerodynamic shape, it is estimated that the spacecraft is kept in the correct orientation by atmospheric drag forces alone. Given the fast altitude drop and change of environmental conditions, the end of flight operations is getting close. [/QUOTE]
