There are a number of modifications that can be installed in the Cargo Bay, one being a convenience feature, and four being material processing units (hereby referred by their acronym, MPUs). MPUs process ore chunks into a powdered form. allowing them to be stored internally as processed ore, removing their volume from the cargo bay, but at the cost of not converting the chunk into powder with the 100% efficiency of Enceladus. Most MPU models also provide remass recovery, allowing part of the water content of an ore chunk to be put into the propellant tank of the ship.
MPUs will not process anything that isn't an ore chunk or ringroid that enters the bay, regardless of their volatility or mineral content (lifepods, dead bodies, spent mass driver rounds, serenity torbernite crystals, etc.)
The galleries for the MPUs will have the roughly-approximate processing areas marked in red. Any ore chunks in these areas will be processed.
Bare Bay Upgrades
Cargo bay baffles
Price: 2,000 E$
Mass: 400 kg
These spring-mounted cargo bay baffles prevent accidental loss of cargo during deceleration.
Springed baffles open inwards only, but may be held open by objects when the bay is very full. Some of the very wide or odd excavator designs host a solid barrier instead of baffles.

Mineral Processing Units (MPUs)
Rusatom-Antonoff MPU
Price: 350,000 E$
Processing capacity: 20 kg/s Power draw: 2 MW / chunk Mineral processing efficiency: 40% Remass processing efficiency: 40% Mass: 1,700 kg Manufacturer: Rusatom-Antonoff
The Rusatom-Antonoff Mineral Processing Unit uses reactor heat to sublimate water content out of a large cargo volume, so that mineral content can be collected and stored. Evaporated water is collected via a cryo-ring, and can be reprocessed into propellant. This MPU boasts minimal power consumption and excellent processing reach, but the heating process is inefficient, and much of the cargo and water is lost during processing.
User Manual
Converts ore chunks into processed ore. Replenishes propellant. Requires ore to be in the processing chamber. Processes multiple ore chunks simultaneously. Power requirements and processing speed listed per chunk. Processed ore stored in separate containers, with capacity limited per mineral type.

Tuning
The cargo bay also has the option to adjust the internal microseismic scanner's focus from -100 to 100 units in sets of 10. This adjusts the side and quality that the bay is scanned. The default focus of 0 covers the entire bay with a decent scanning resolution, a focus of 100 or -100 will cover the top or bottom (respectively) quarters of the bay with a very high resolution. Values inbetween will have the resolution skewed between the top and bottom of the bay.
