I recently sent an unmanned rover mission to Duna. I fully tested all parts of the rover at KSC runway, including the sample grabber, to ensure that everything functioned before sending it out. All of the parts functioned properly at the runway. However, once landed on Duna the Sample Grabber no longer functions. The button to run the experiment comes up in the parts manager window, but when pressed it only says Invalid Research Location. Help please if anyone has any ideas. Oh, and v 0.2.1.0 for referance.
Nevermind, I solved this issue! Always remember folks to check and adjust your suspension settings when under a different gravity effect than your test environment!
