Hrequests: Name of 60s-70s space horror film

I've been searching for the name of a gothic horror movie from the late 60s or early 70s. Some number of astronauts land on a desert planet that is populated by tall carrot-shaped creatures that have an infrared eye. One by one the astronauts meet terrible deaths. One astronaut is burned to death by one of the carrot aliens in a very graphic way. Another walks into a sphere that appears near the space craft and is flash-frozen. I recall seeing this gore-fest on television as part of weekly horror/scifi movie time. The movie has some of the same feel as Journey to the Far Side of the Sun (1969). Does this movie sound familiar?
