Scientists: Yutu-2 spots tiny glass globules similar to those found by Apollo astronauts
According to a paper just published Chinese scientists running the Yutu-2 rover on the far side of the Moon have spotted several tiny glass globules similar to those found by Apollo astronauts.
Xiao and his team believe the small spheres, which are between 0.59 and 0.79 inches (1.5 to 2.5 centimeters) across, were probably formed by relatively recent meteor impacts. Specifically, the researchers believe that the globules formed from anorthosite, a volcanically-formed rock rich in the mineral feldspar, after a high-energy impact melted the rock and reformed into spheres.
In appearance these Yutu-2 globules appear translucent, unlike the Apollo globules which were either dark or opaque. Since the rover did not do spectroscopy on these objects before moving on, however, their actual make-up is unknown, with the speculations by the researchers above merely that, speculations, though reasonable.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
