Query: FRIPON: A worldwide network to track incoming meteoroids   Context: Until recently, camera networks designed for monitoring fireballs
worldwide were not fully automated, implying that in case of a meteorite fall,
the recovery campaign was rarely immediate. This was an important limiting
factor as the most fragile - hence precious - meteorites must be recovered
rapidly to avoid their alteration. Aims: The Fireball Recovery and
InterPlanetary Observation Network (FRIPON) scientific project was designed to
overcome this limitation. This network comprises a fully automated camera and
radio network deployed over a significant fraction of western Europe and a
small fraction of Canada. As of today, it consists of 150 cameras and 25
European radio receivers and covers an area of about 1.5 million square
kilometers.
