NASA: Apollo Experiments 40 years ago reveal Moon core same as Earth

Apollo experiments from 1969 to 1977 revealed that moon has a core apparently the same as the Earth’s core, according to a report from National Aeronautics and Space Administration (NASA) on Thursday.

NASA researchers was reported to have been discovered that the state-of-the-art seismological techniques that were applied to Apollo experiments made 40 years ago seem to suggest the moon we know has a core similar to that of planet Earth’s.

Apparently, NASA said that the their findings suggest that the moon possesses a solid, iron-rich inner core with almost a radius of nearly 150 miles in and a fluid, mainly a liquid-iron outer core with about 205 miles in radius.

The Apollo Passive Seismic Experiment data also showed that the moon’s core is somehow a molten boundary layer around the core approximately 300 miles in radius that make it differ from the earth’s core.

According to NASA’s recent research, the lunar core contains a small percentage of light elements such as sulfur, echoing new seismology research on Earth that suggests the presence of light elements such as sulfur and oxygen, in a layer around our own planet’s core.

As mentioned earlier, the extensive data gathered during the time of Apollo moon missions was used by NASA researchers. The Apollo Experiments were consisted of four seismometers deployed from 1969 and 1972, which recorded continuous lunar seismic activity until the late months of 1977.

“We applied tried and true methodologies from terrestrial seismology to this legacy data set to present the first-ever direct detection of the moon’s core.” NASA‘s Marshall Space Flight Center space scientist Renee Weber said, who was also the leader of the research team.
