Sep 10, 2021Updated online version of the 3rd AGILE TGF Catalog, including events up to October 31, 2020

We announce that the SSDC online version of the 3rd AGILE Terrestrial Gamma-ray Flashes (TGF) Catalog, initially including events detected by the Minicalorimeter (MCAL) during the period March 2015 - September 2018 (A. Lindanger et al. 2020 and C. Maiorana et al. 2020), has been recently updated to include 517 new events associated with lightning sferics detected from October 1, 2018 to October 31, 2020. The total number of AGILE TGF events associated with lightning sferics from March 2015 to October 2020 is more than a thousand (1116).
The complete SSDC AGILE TGF web table is available here, and it also gives access to the available TGF light curves and counts details, providing supplementary material to the published papers. The current version, published online on September 2, 2021 also includes minor bug fixes affecting the previous plotting of some of the TGF lightcurves during the so-called DRIFT period (see references for more details).

Jun 30, 2021Asteroid Day: the SSDC contribution to asteroid science

In memory of the Tunguska asteroidal event, occurred on 30th June 1908, since 2014 this day is named Asteroid Day.
The study of asteroids is raising interest over the years and, over the last period, the attention to the threat that Near Earth Asteroids (NEA) potentially represent for human civilization has become an hot topic.
SSDC actively participates to a series of programs expressely dedicated to physical and orbital characterization of these objects, in particular by taking part in the H2020 NEOROCKS project, the LICIACube mission and in the future constitution of a long lasting ASI-SSDC NEO Physical Properties Data Center.

NEOROCKS

NEOROCKS is an H2020 funded project aimed at improving our knowledge of the physical characteristics of the NEO population, in which SSDC is contributing by allowing for a better exploitation of data coming from different sources, using standard protocols to build a database that will be publicly accessible through a web portal with advanced functionalities.
This novel application will allow to easily crossmatch different datasets in order to better identify potential hazardous objects and to adequately plan follow-up observations.

LICIACube

LICIACube is an Italian mission targeting the Didymos-Dimorphos asteroid system to be launched in the fall 2021, that will be carried on by the NASA DART spacecraft for 10 months and will collect images of the effects produced by the DART impact over the Dimorphos surface. LICIACube is equipped with two different cameras, a panchromatic one named LEIA and a RGB one named LUKE, that will allow to perform several studies related to the surface characteristics, the plume generated by the impact and the computation of the shape model for Dimorphos.
SSDC is involved in the LICIACube mission for data exploitation and preservation, and it will host the Scientific Operations Center which will organize, calibrate, and distribute the data to partner organizations (e.g. NASA) and to the scientific community through the MATISSE SSDC tool.
