Hello.
Did you ever wonder how the kerbals where able to know all science facts about planets such as gravity they never visited ?
Well I did.
There for I would like to suggest that before a planet/moon have been visited by a spacecraft then I think the information panel of planet/moon should contain less information.
For example to get information about gravity then I think it would be kind of logical that a spacecraft had to do a little science when doing a flyby or an orbit to unlock such information.
What do you guys think ?
