Still learning new things from Apollo samples, 40 years later.


Ever since July 20, 1969, when Neil Armstrong left the first human footprint on the surface of the moon, scientists have been fascinated by the fine powdery soil in which it was made. Today, more than 40 years later, Carol and Christopher Kiely are using a new imaging technique called X-ray ultramicroscopy (XuM) to examine the internal structure of the lunar soil particles that were collected from the Sea of Tranquility during the Apollo 11 mission.

“These particles are like tiny time capsules,” says Carol Kiely, an adjunct professor in the department of materials science and engineering at Lehigh Univ., “providing us with clues to all the geological processes that have occurred on the lunar surface for the past 3.5 billion years.”

And it's cool what they found - a type of particle not found on Earth, formed due to high energy micro-meteorite impacts.

Gotta love science.
