Meteor and fireball observations are key to the derivation of both the
inventory and physical characterization of small solar system bodies
orbiting in the vicinity of the Earth. For several decades, observation
of these phenomena has only been possible via ground-based instruments.
The proposed JEM-EUSO mission has the potential to become the first
operational space-based platform to share this capability. In comparison
to the observation of extremely energetic cosmic ray events, which is
the primary objective of JEM-EUSO, meteor phenomena are very slow, since
their typical speeds are of the order of a few tens of km/sec (whereas
cosmic rays travel at light speed). The observing strategy developed to
detect meteors may also be applied to the detection of nuclearites,
which have higher velocities, a wider range of possible trajectories,
but move well below the speed of light and can therefore be considered
as slow events for JEM-EUSO. The possible detection of nuclearites
greatly enhances the scientific rationale behind the JEM-EUSO mission.
