Opening the Main Pressure Housing

The majority of the electronics inside the Odyssey IV are inside a glass sphere near the top of the vehicle's interior. Today we opened the sphere to do some work calibrating the RTU.

There is quite a lot of stuff packed into this 17" diameter space, including the PC104 mainboard, 2 large thruster motor controllers, and the RTU controller. The water cooling system you see here is actually for the thruster controllers, not the main CPU.


With the top half of the sphere removed, you can see the method we use to quickly disconnect the inside of the sphere's penetrators from the rest of the electronics.
