Insight Mars Lander
InSight is a robotic lander designed to study the deep interior of Mars. It's managed by NASA, and most of its scientific instruments were built by European agencies. The mission launched on 5 May 2018.
This replica is as accurate as I could get get in size. It has retractable landing gear, two deployable experiments (Seis and HP3) with his 3 axis robotic arm (it's a challenge) and of course the two round deployable solar panels.
use slider 1, 2 , roll, pitch and yaw with auto stabilisation off to control the arm.
