Brownleeite
Template:Short description Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters". Brownleeite is a silicide mineral with chemical formula MnSi. It was discovered by researchers of the Johnson Space Center in Houston while analyzing the Pi Puppid particle shower of the comet 26P/Grigg-Skjellerup. The only other known natural manganese silicide is mavlyanovite, Mn5Si3.[1]
Overview
The particles were collected from the stratosphere over south-western US in April 2003 using an ER-2 high-altitude research aircraft of NASA. The team of researchers from US, Germany and Japan was led by NASA scientist Keiko Nakamura-Messenger.[2][3]
To determine the mineral's origin and examine other dust materials, a new transmission electron microscope was installed in 2005 at Johnson Space Center.[4]
The mineral name was approved by the International Mineralogical Association (IMA Number 2008-011).[5] The NASA scientists named the mineral after Donald E. Brownlee, professor of astronomy at the University of Washington, Seattle, because of his pioneering research on interplanetary dust particles.[6]
