SUMMARY

The Apollo Command Module (CM) utilized helium tanks primarily for the reaction control subsystem, which was essential for propellant feed during attitude control. This system was crucial for maneuvering the spacecraft, especially during re-entry after the Service Module was jettisoned. The discussion highlights the importance of helium in maintaining stability and control of the CM throughout its mission phases.

PREREQUISITES

TL;DR
Why were there tanks of helium on the CM?
Hello All

Diagrams of the Apollo Command Module show tanks of helium, What was this used for?

best regards ... Stef

I think it was used to feed propellent for attitude control and perhaps the big engine. Were these in the Service module or the command module?
 
Of course you would still need attitude control thrusters for re-entry (after ejecting the Service module). Duh I didn't even think it through.
