Resistors

Can be 60 W rated.
Low inductance, huge overload tolerance.
One shall recall Little Devils, which are epoxy encapsulated.
Google picture of the first American satellite insights.
Dale resistors are the wirewound ones - inductive - no good for anything but DC.
As it was correctly noticed, they do require external heatsink...
Counterpart С5-47
BTW It has nothing to do with space exploration and low price on Energia rocket engines, namely RD-180,
Ceramic encapsulated carbon comp. TBO [t-v-o] Near extinction type.POCKOCMOC (Roscosmos) thinks the green one is 10W resistor.
NASA thinks the gold one is 50W resistor.
Seriously, does anyone has some more info on those russian power resistors? I can say that leads are magnetic, but resistor body is not.

So that gold one can operate on higher temp than the green one? Probably the gold one is build from better materials.

Dont think so, it is smaller, but without heatsink you wont get any 50w rating out of then, maybe not even 10w

RH-50: Actually about 12W without heatsink.. Derating further is a good idea however.

These are actually pretty rugged and stable resistors. I use them a lot in my designs. There is also a non-inductive type available.
