Newly discovered temperature data from the 1970s moon landings, released in the Journal of Geophysical Research in April, reveals that NASA astronauts probably warmed up the moon's surface temperature by as much as 6 degrees Fahrenheit by walking around and poking into the lunar surface. The data comes from so-called heat-flow experiments that were installed on the moon in 1971 and 1972 during the Apollo 15 and Apollo 17 missions. For the experiments, astronauts on each mission drilled two holes into the surface of the moon at depths ranging from 3.2 feet to 7.5 feet deep. The astronauts inserted fiberglass...
