Drilling a star.

I had the chance to find a ship with an already installed, uh, in english, it may be ultraprobe ? ultrasensor ? (ultrasonde). So I happily went near a star to test my new toy.
Without thinking about the absence of background for the star approach screen I posted on elsewhere, I launched the thing to check if it will be a good investment in my futures games ... Well, for the moment it looks like it's not, but the problem is not there :
After the harvest of fuel, the screen shows off the usual "terminate", but the "launch sensor" button was replaced by the "drill" one, as if I was on a rocky planet. Using it didn't result in anything.

Hi Esdeve,

Ok I check that.
