Nov 05, 2018NASA Dawn mission ends after 11 years

NASA Dawn mission, the first one to explore two different objects of the main asteroid belt (Vesta and Ceres), ended few days ago after missing two scheduled communication sessions with NASA's Deep Space Network on Wednesday, Oct. 31, and Thursday, Nov. 1.

The mission lasted 11 years and, among its precious scientific results, those regarding the composition of Vesta, that has been confirmed as the parent body of the HED meteorites and the discovery of a large carbonates deposit forming a peculiar bright spot inside the Occator crater of Ceres can be cited.

SSDC contributions to Dawn are twofolds: the availability of the VIR imaging spectrometer data through the MATISSE tool, and the participation of Marco Giardino (SSDC ITC Manager) to the mission Dawn Archive Working Group.

The VIR-Dawn data available through MATISSE have been also used for educational purposes, an activity now part of the curriculum of the "Introduction to Modern Astro-Plasma Physics" course of the East Windsor Regional School District in Hightstown, NJ (USA).

Oct 10, 2018SSDC interactive analysis tools among US Students: an american public school pioneer project

As part of the collaborative efforts with SSDC, Dr. Franco Paoletti incorporated two remote space data analysis activities in the curriculum of the "Introduction to Modern Astro-Plasma Physics" course, recently approved by the Board of Education of the East Windsor Regional School District in Hightstown, NJ (USA).

The two activities will see students analyzing data coming from both Solar System exploration and high-energy observations of the Universe, and will be performed using the SSDC interactive online analysis tools: MATISSE for Solar System observations and AGILE-LV3 for the gamma-ray AGILE satellite data.

The activities point to reproduce published scientific results, such as the characterization of dark material on the Vesta asteroid (e.g. Palomba et al., 2014) and the analysis of a couple of exceptional bright flares seen in gamma-rays from monster black holes in distant galaxies (e.g. Astronomer's Telegrams: ATel #9186 and ATel #7631).

The final goal is to provide the students with knowledge, skills, and competences required to correctly use tools specifically designed at our data center for professional researchers, and to get a better understanding of the day to day work of an astrophysicist.

Jun 26, 201816th AGILE Scientific Workshop: presentations available

We are pleased to announce that all the presentations authorized for distribution given during the 16th AGILE Workshop "Fast and AGILE: Multimessenger Astrophysics and Beyond" (ASI, 18 May, 2018), are now publicly available.

The slides (pdf format) may be viewed, together with the final program and the recorded videos of the event, at the Workshop web site. On behalf of the Workshop SOC and LOC, we thank very much all the participants.

Jun 21, 2018New AGILE Public Data now available up to May 31, 2018

We announce the publication of new AGILE gamma-ray data. The public AGILE archive now contains all data from December 1, 2007 to May 31, 2018, i.e. from the start of Cycle-1 up to the on-going Cycle-11. AGILE-GRID event files (EVT) and spacecraft auxiliary (LOG) files are available from the SSDC Multimission Archive (MMIA) webpage for the AGILE Mission.

We recall that, starting from October 2015 the standard one-year proprietary period was eliminated, and all AGILE-GRID data are now published as soon as they are processed and validated. The new public AGILE Cycle-11 data were obtained with AGILE observing a large portion of the sky in spinning mode, and they have been processed with the latest public software and calibrations.

For an easy on-line AGILE data analysis, we recall that the interested user may also query the entire public AGILE level 3 (LV3) archive through the AGILE-LV3 data analysis tool.

Jun 11, 2018MATISSE v1.5 online with a better 3D online visualization method

A new version of MATISSE (https://tools.ssdc.asi.it/matisse.jsp) has been released, with the major update regarding the 3D online visualization method.
Thanks to the use of a new javascript (https://kitware.github.io/vtk-js/) it is now possible to directly view online the 3D high-resolution models for the great part of the MATISSE targets, including the comet 67P, Vesta, Ceres and Venus, thus overtaking the limitation for larger objects present with the previous technology used.
This version has been labeled v1.5 and comes after the implementation of the SAMP protocol to interoperate with VESPA datasets (v1.3) and the addition of the 1 and 2 micron spectral parameters for VIR-Dawn observations of Vesta (v1.4).

Apr 23, 2018NASA's Transiting Exoplanet Survey Satellite (TESS) mission has been launched

The NASA's Transiting Exoplanet Survey Satellite (TESS) mission has been launched on April 18 aboard a SpaceX Falcon 9 rocket. The mission will be devoted to the discovery of habitable planets around the brightest stars in the solar system neighbourhood through the detection of planetary transits during a two years survey. The mission will exchange its results with the ESA small mission CHEOPS that will be lanched at the end of 2018, dedicated to characterize a sample of systems known to host exoplanets but also to improve parameters of newly discovered ones.

Apr 06, 2018New AGILE Public Data Now Available up to December 31, 2017

We are pleased to announce the publication of new AGILE gamma-ray data.
The public AGILE archive now contains all data from December 1, 2007 to December 31, 2017, i.e. from the start of Cycle-1 up to the start of the on-going Cycle-11. AGILE-GRID event files (EVT) and spacecraft auxiliary (LOG) files are available from the SSDC Multimission Archive (MMIA) webpage for the AGILE Mission.

We recall that, starting from October 2015 the standard one-year proprietary period was eliminated, and all AGILE-GRID data are now published as soon as they are processed and validated. The new AGILE Cycle-10 and Cycle-11 data which become public today were obtained with AGILE observing a large portion of the sky in spinning mode, and they have been processed with the latest available software and calibrations.

For an easy on-line AGILE data analysis, the interested user may also query the entire public AGILE level 3 (LV3) archive through the AGILE-LV3 data analysis tool. By simply entering in the AGILE-LV3 web form the source name or coordinates of the object of interest and clicking on one of the 'Interactive Analysis' buttons on the query-result table, the user can execute the official AGILE Maximum Likelihood (ML) analysis in each available time bin of the chosen duration (default is 28 days).
By selecting more than one time bin, with a click of the mouse it is also possible to generate in few minutes the complete gamma-ray light curve above 100 MeV over the selected period with default analysis parameters.

The AGILE-LV3 tool is meant to be easily comprehensible, even without many instructions and it does not require any install-on-premises software or calibrations. Your feedback will be greatly appreciated.
