My surface sismo doesn't Work

[Bicodabaguete]

I get a task who told me to put a surface sismo (From Braking ground) on mun and get 50% of science, but the science don't increase with time. I check the solar panels several times and i put them closer. i realy don't know what to do.

Did you put down a control station with it?

Do you have a communication connection?  The mun is tidally locked, so if you put it on the surface and it doesn't have line of sight with Kerbin, you'll need a relay to get the signal there as it will never rotate into view of the KSC.
