Hearts of Space
https://www.hos.com/
 
I used to listen to them a long time ago  and I was surprised to find out it's still around.  I don't really know anything about submitting music to them or even if they accept submissions  but it would be worth a try.
Edit They have submission guidelines in their FAQ

I usually don't go for this type of music, but I thought it was very good.
 
I also remember Hearts of Space. UMSL college in St. Louis back in the 80's had a radio station and they played that program along with a progressive jazz program called Miles Beyond and a terrific jazz-rock program called Fusion 97. (The station was at 97 on the FM dial.) Cut my musical teeth on the latter too. Hearst of Space wasn't my cup of tea, but I listened to it once in a while.

Adrian, this really changed my mood.  It gave me a lift just when I needed it.  Stay prolific, my friend!

Thank you for the helpful input about outlets for my musical ramblings it is appreciated.
 
Thanks Wayfarer I will check out Hearts of Space.
 
I am glad that I helped change your mood Lynn. As long as the Muses provide me with inspiration hopefully the tunes will continue to flow.
