He founded the field of interplanetary dust particle (IDP) research.  Among several honors, he was awarded the Leonard Medal from the Meteoritical Society, and Asteroid 3259 was renamed Brownlee. Dr Brownlee designed a particle collector that was mounted on a NASA aircraft and flown in the lower stratosphere for the purpose of sampling the dust stream of Comet 26P\u002FGrigg-Skjellerup in 2003.  This mineral was among the particles collected and is the first new mineral found that is thought to have originated from a comet.","2025-10-31 20:01:57",[],[],[],[],[44],{"id":45,"txt":46,"latitude":11,"longitude":11,"country":47},188570,"Comet 26P\u002FGrigg-Skjellerup, Outer Space","Outer Space",[49,53,58,62,65,68,71,75,79],{"id":50,"year":51,"html":52,"doi":11},16137497,1957,"Boren, B.
