I can be a little more generous with my clipping plane setup, so for most orbits, I won't need a terrain renderer for some time, at least.

Great video from Scott Manley talking about ESA's Jupiter Icy Moons Explorer mission (JUICE) - which is scheduled for launch in a few hours (13:15 UK time). Going off to explore Europa, Callisto and finally entering into orbit of Ganymede - the largest human spacecraft to go into deep space, and the first to orbit another moon.

Really excited to see what they find while exploring these moons!
