The post-aerobraking status is that everything is exactly the same as at the start of aerobraking. Astrium built VEX very well. The post-aerobraking series of pericentre raising maneuvers were fine, and we got bumped up out of the atmosphere. We've been operating nominally ever since.We are within the error bands of our bookkeeping fuel measurements. That means that we could run out of fuel at any time; we just don't know. Every day we do minor momentum dumps, but the most likely time it will happen is during an orbital correction maneuver (OCM) used to do the regular pericentre raising required at Venus. Our next set of OCM burns is beginning 23 November and is repeated for about 10 orbits. If we survive past that set of burns, the next set is in February. If we survive past that, the next set of burns is in June. And so on.Scientifically, we're using our remaining time on two main issues, both related to volcanism: looking for surface volcanic activity with the infrared channel of our low resolution camera; and looking at atmospheric SO2 levels. The SO2 levels in the atmosphere have seen dramatic changes between the previous missions and VEX; and the levels are dropping over the lifetime of our mission. So it may be an indication of volcanic activity replenishing SO2 levels, which then drop. There are other activities, as well.
