NASA Logo Designer Bashes Donald Trump's Space Force

Donald Trump's amateurish designs for potential Space Force logos are out-of-this-world bad ... so says the artist who created an older NASA logo.

Richard Danne -- the designer of a NASA logo from 1975 -- went off on Trump's Space Force artwork.

Danne ripped into the designs released by the Trump Administration ... telling TMZ, "This logo effort is typical of the present administration: impulsive, ill-advised, superficial, and second-rate."

Tell us how you really feel, Richard!!!

"A random student from the Los Angeles Art Center could put these logos to shame ... They are, in a word: sophomoric!"

Richard is peeved some of the Space Force designs were lifts from past NASA logos.

"The images are totally derivative from NASA graphics but are -- All flash and no substance, and comical really."
