Sep 22, 2022SSDC Solar System group at EPSC 2022

This week Edoardo Rognini and Veronica Camplone are at the European Planetary Science Congress in Granada, Spain, with the work "Mercury exploration with MATISSE tool".
The combination of a thermophysical model and the capability of selecting data basing upon geological maps, makes MATISSE a very powerful tool for the study of the first planet of the solar system.
A capability that would become crucial with the ESA-JAXA BepiColombo mission approximating its scientific phase.

Jul 22, 2022AGILE news

AGILE, PUBLISHED THE FIRST ARTICLE ABOUT THE "NEW YEAR'S BURST"

The first article about the GRB 220101A, the exceptionally energetic "New Year's Burst", has been published by AGILE on July, 15, 2022 (Ursi et al., ApJ 933, 2022).

Few hours after the midnight of January 1, 2022, several satellites devoted to high-energy astrophysics, including AGILE had greeted the beginning of the new year by revealing what is probably the most energetic Gamma-Ray Burst (GRB) ever reported in the history of the observations of these phenomena, i.e., the GRB 220101A.

In its 15 years activity, AGILE has already had the opportunity to reveal some particularly intense GRBs, such as the GRB 080916C and the GRB 160625B, but these events are quite rare. GRB 220101A took place more than 12 billion light years away, at the time when the Universe was just about 1.3 billion years old, and its equivalent isotropic energy is the highest ever reconstructed for a GRB.

This record-breaking energy has drawn a great deal of attention from the scientific community in a short time. In the following days, more than twenty GCN communications were released, reporting observations carried out by other space missions and by astronomical ground-based observatories.

AGILE data provide a first characterization of the prompt phase of this GRB, which corresponds to the emission of high-energy radiation in the initial shocks taking place within the central engine. The different detectors onboard the satellite, whose energy coverage ranges from the X-ray (SuperAGILE 20-60 keV) to the gamma-ray (AGILE-MCAL 0.4-100 MeV) band, allowed to provide a first comprehensive overview of the temporal evolution and the energetics of this event. Using AGILE data together with public data from the Swift satellite, it was also possible to study also the so-called "afterglow" emission, that is, the delayed emission at lower energies, produced by the interactions of the initial shocks with the surrounding interstellar medium. This analysis allows to obtain interesting information regarding the environment in which such energetic event took place.


NEW AGILE TGF CATALOG UPDATE UP TO DECEMBER 31, 2021

AGILE confirms itself as an exceptional instrument, not only for the observation of cosmic phenomena, but it continues to give fundamental contribution also for the observation of high-energy phenomena from the Earth, such as the Terrestrial Gamma-Ray Flashes (TGFs) (A. Lindanger et al. 2020; C. Maiorana et al. 20209). Recently all TGFs seen by AGILE up to 31 December 2021 have been published as an interacting SSDC web page, including details and additional information compared to the original publications of the third TGF catalog in 2020.

Jun 06, 2022Paper about SSDC activities for LICIACube published

A paper describing the role of SSDC in the LICIACube mission has been recently published on the Planetary Science Journal.

Led by Angelo Zinzi, coordinator of Solar System Exploration activities in SSDC, the paper focuses on the preparation of the mission Science Operations Center (SOC), hosted and managed by SSDC.

The LICIACube SOC is in charge of processing and archiving the data. Raw images will be calibrated using algorithms developed by INAF. Both raw and calibrated images will be archived following the PDS4 standard, so that, after the proprietary period lasting 9 months from the DART impact on Dimorphos, they can be publicly released straightaway.

The paper also describes how the SSDC MATISSE webtool is being adapted to fully exploit LICIACube images, main changes including new geological functionalities and a new thermophysical model, best suited for small, rubble-pile asteroids.

Mar 09, 2022Mercury NASA MESSENGER's images on MATISSE

Last week an update on the MATISSE webtool, made it possible to search and retrieve calibrated images from the NASA MESSENGER MDIS-NAC camera using the NASA ODE REST protocol.
This is a crucial addition, taken into account the thermophysical model already available for Mercury and the work on the geological units planned to be released in the next months.
All these new functionalities could be of major interest for the study of Mercury, in preparation for the ESA-JAXA BepiColombo mission, presently on its way to starting orbiting the planet in 2025, making MATISSE a useful tool for data exploitation.
