Description
Whenever enough time is available for the impact to occur, satellites could be operated to retrieve observations of the atmospheric event. This session is foreseen to present current satellite capabilities which could be employed for these observations.
The Meteosat Third Generation Lightning Imager (MTG LI) will perform the geostationary detection of lightning optical emissions from space. Such radiation is produced by electric discharges within or below a cloud and reaches the cloud top after multiple scattering. The LI is designed to sense this cloud-top emission within a 1.9 nm wide band centred on 777.4 nm, with a 4.5 km resolution at...
The Geostationary Lightning Mapper (GLM) instrument onboard the GOES 16 and 17 satellites has been shown to be capable of detecting bolides in the atmosphere. Due to its large, continuous field of view and immediate public data availability, GLM provides a unique opportunity to detect a large variety of bolides, including those in the 0.1 to 3 m diameter range that complements current...
NASA’s Planetary Defense Coordination Office (PDCO) was established to manage NASA’s planetary defense-related projects and coordinate activities across multiple U.S. agencies (along with international efforts) to plan appropriate responses to the potential asteroid impact hazard. PDCO currently funds four ground-based survey capabilities (and re-purposed astrophysics survey instrument in...
Only a handful of proxy strength measures are available for decameter and smaller NEAs. One data source which can address the question of meter-sized NEO structural strength is the recent release of over 800 light curves for bolides detected by US Government sensors since 1988. A subset of these events (about 270) also have trajectory, speed and height at peak brightness information. These...
