Brownleeite is a silicide mineral with chemical formula MnSi. It was discovered by researchers of the Johnson Space Center in Houston in April 2003 while analyzing the Pi Puppid particle shower of the comet 26P/Grigg-Skjellerup. The only other known natural manganese silicide is mavlyanovite, Mn5Si3.

== 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.
