I read this story in an old comic book about a space traveler who lands on a planet of spiders. They invade his spaceship and one of them bites him. He returns to Earth but realizes he is infected. He also knows the spiders can travel on radio waves so he remains on radio silence. He finally drops a capsule with his story and the Earth defenses blow him out of the sky. Probably read it in the 1960s. What was the comic?
