Some more ATV training with Sasha today!
We starting delving into the world of rendez-vous and docking malfunctions: all those scenarios that would cause us to send a manual command to interrupt the approach of ATV.
We also had an evaluation simulation on ATV emergencies, in particular the cases of fire in ATV and of a Station depressurization with the leak located in ATV.
A lot of the emergency procedures are common to generic station-wide response we train in Houston, but there are some peculiarities related to ATV. The main one is that it is a vehicle that can, and must eventually undock Station. If you’re going to close the hatch of ATV in an emergency knowing that you will never open it again, you better make sure you leave the vehicle in a configuration in which it can safely undock and fly autonomously until atmospheric reentry!
All the ingress operations we worked on yesterday were very helpful for today’s sim, because we were familiar with the location of equipment. In the picture, you can see us yesterday working on the installation of the air filter.
