• When NASA's Apollo astronauts landed on the moon, they drilled probes into the ground to monitor the moon's temperature.
• Apollo mission researchers later noticed that the probes recorded peculiar warming on the surface of the moon.
• New data suggests that by walking around and poking into the lunar surface, the astronauts themselves changed the temperature on the moon.

The old explorer's adage says to "take only photos, leave only footprints."

But it seems the footprints of NASA's Apollo astronauts had unintended consequences for the surface of the moon after they landed there nearly 50 years ago. See the rest of the story at Business Insider
