Satelite contract doesn't work

[BABLBAM]

 I sent probe to equal orbit, game said, that orbit was equal, probe had required things (solar panels, materials bay, antenna), and it said, that every part of contract is done except: "Build an unmanned probe that has an antenna and can generate power". So, why the contract isn't completed? Everything was ticked except that thing. Why?

Welcome to the forum

You probably used a wrong part: Do you know that the 'materials bay' is not a service bay but a 'SC-9001 Science Jr'?

Another possible reason: Did you use a manned ship to deploy the probe? Sometimes the game gets confused and doesn't recognize the probe to be 'unmanned' after decoupling. If you use a unmanned rocket to deploy the probe in space, this part of the contract should already be checkmarked on the launchpad.

Any chance you were going the wrong direction?  Very common on those to go the wrong way.

Also, it seems to happen sometimes that creating a quicksave and then reloading that quicksave will suddenly make the contract complete.

Did they fix the bit where a relay antenna didn't count for it?
