Yes there's no atmosphere, so you might think that they can't hear each other.
But they still can use Radio Frequency , can't they? If you ever have wondered how astronauts communicate in Space , its the answer. Radio Wave is applied here!
And Radio Wave is Electromagnetic Wave . And you know well how fast is the speed of Light (Electromagnetic Wave) ,don't you? So it has a LARGER Frequency.
So they can hear each other with HIGHER, Radio Frequency !
