New Center research presented at Meteoritical Society Meeting

Ask a Curator Day

Posted on July 23, 2019 by Center for Meteorite Studies

This July, several members, alumni, and affiliates of the Center for Meteorite Studies presented new findings at the 82nd Annual Meeting of the Meteoritical Society in Sapporo, Japan.

The Center's presentations covered a broad range of topics in meteoritics and cosmochemistry, including water on Mars, aubrites, ureilites, meteorites from the moon, carbonaceous chondrites, and processes in the Early Solar System.

Fusion crust! Also, lunar basalts don't contain hydrous minerals like amphibole or mica. Chemical testing is used to definitively ID lunar meteorites - @WUSTL_EPS has tons of great info, here: https://bit.ly/2FP1UC1

September's #MeteoriteoftheMonth is Plantersville, an ordinary (H6) chondrite that fell in #Texas the afternoon of September 4, 1930. #meteorite

Interesting article here (link below) detailing how the joint @esa @JAXA_en spacecraft @BepiColombo will perform a flyby of #Venus next month and use this opportunity to look again for #phosphine "up close".

The odds are very low, but we don't know of all the asteroids that cross Earth's orbit. So it is very important that astronomers keep searching for them.
