he NASA , in collaboration with researchers from the U.S., Japan and South Korea, has found anew mineral called wassonita one of the meteorites recovered most historic in Antarctica in December 1969. The new mineral was discovered in the meteorite Yamato 691, which were obtained lunar samples collected by Apollo.
The meteorite Yamato 691 can probably be caused by an asteroid that orbits between Mars and Jupiter. The wassonita is among the smallest but most important minerals identified in the sample, which dates back 4,500 million years ago. The research team led by NASA scientist Keiko Nakamura-Messenger, mineral added to the list of the 4,500 officially recognized by theInternational Mineralogical Association .
"The wassonita is a mineral consisting of only two elements: sulfur and titanium, however, has a unique crystalline structure that has not been previously observed in nature, "said Nakamura-Messenger.
In 1969, members of theJapanese Antarctic Research Expedition found nine meteorites on blue ice field of the Yamato Mountains in Antarctica. This was the first significant recovery of Antarctic meteorites and samples of different types represented. As a result, the United States and Japan conducted a systematic follow-up search for meteorites in Antarctica, which recovered more than 40,000 specimens, including lunar and Martian meteorites extremely rare.
