IIUC, it has 12 strategically arranged RCS and 2(1 broken) main thrusters, ALL installed on a back facing mounting plate now pointing spaceward. I'm kind of suspecting there could have been cool factor involved in the decision leading to this design.
So, a pair of thrusters tilted 45 degrees up and down like ailerons can be called roll thrusters, and anyone who says that in deadpan straight face as an actual spacecraft engineer is completely insane, right?
Was hoping a spacecraft engineer would explain why tilted thrusters can't create enough angular momentum to roll the probe in terms which a humble software engineer would understand.
