Superb!
Getting stuck into the rebuild of the 2001 Orion, checking the old model.

The geometry is a GREAT fit to my references. So far I upscaled the texture maps, and killed a few bad polygons.

It clearly needs lots of bump maps replaced by geometry and normal maps though...

My old painting of a brown dwarf.
This view represents a moon of a brown dwarf being lit up by the sun-like star, which is second component of this star-brown dwarf system.

Today’s prompt in @spacetober_challenge is Star. I thought I’d share a digital composition that I ve created and use as part of my Sciart & science art workshop resources. Science outreach is one of my passions - the sharing of science knowledge through fun and creativity. #Spacetober #Sciart

The "Discovery" from 2001 at one point had tension cables along the spine, and large cooling vanes, (required for the nuclear engines).

Here's my take on that

Another alternate design for 2001's "Discovery", this version is generally known as the "Dragonfly" design.
