Interstellar bow

Illustration by Jean Luc Beghin for the 1970 edition of Spirou.

The top-right text says the image doesn’t depict any particular moment during the Apollo missions but that the two astronauts were picked arbitrarily: Frank Borman, commander of Apollo VIII (the first mission to fly around the moon) and Neil Armstrong, commander of Apollo XI (and the first person to walk on the moon).

I cleaned this image up a bit and the source-file can be found here, as well as other high definition scientific illustrations.
