Saturday GOCE status update from ESOC
This sent in just a couple hours ago by ESA’s GOCE Operations Manager Christoph Steiger, at ESOC.
This morning GOCE was at an altitude of around 160 km. As expected, the drag levels have increased very much, with the average now around 90 mN (milliNewton).
Despite the extreme environmental conditions, we had a problem-free acquisition of signals from the spacecraft this morning (meaning that the ground station found GOCE pretty much in the orbital position it was predicted to be). The attitude control of the spacecraft is performing very well. Data from the Gradiometer is now only usable for part of the orbit, when drag levels are below 80 mN and the accelerometers are hence not saturated.
Recently we have noticed a significant temperature increase in several areas of the spacecraft, arguably linked to GOCE encountering a more and more dense atmosphere as its orbit keeps dropping.
GOCE is expected to fall by over 13 km today, with the final re-entry into the atmosphere probably less than 2 days away.
