June 28, 2016 ASDC participation to high-school outreach program

In mid June 2016, twenty high-school students from Liceo Classico "Aristofane" and Liceo Classico "Giulio Cesare" of Rome, spent one week at the Headquarters of the Italian Space Agency (ASI) to participate to the "Alternanza Scuola-Lavoro" (School and Work synergy) project, according to the new indications of the Italian Ministry for Education, University and Research (MIUR) aimed at giving a real work experience to high-school students.
On June 17, 2016, the students used ASDC tools to analyze data coming from both Solar System exploration and Universe observation missions, under the guide of Stefano Ciprini, Dario Gasparrini, Fabrizio Lucarelli, Carlotta Pittori and Angelo Zinzi.
After a brief introduction by Ciprini and Pittori on the astrophysical observations of the Universe, and by Zinzi on the exploration of the Solar System, the students were divided into four groups of five persons each. The students chose their preferred field of analysis, so that two groups used planetology ASDC tools and the other two groups used Universe observation ASDC tools.

The planetological analysis was carried out by looking at data acquired by VIR spectrometer onboard NASA Dawn mission over the asteroid Vesta. The search for the data was conducted using the ASDC tool MATISSE, whose output (in FITS format) was then passed on to the JS9 tool to evaluate the 1.98 μm band depth, on the basis of the work by Palomba et al. (2015) devoted to the characterization of dark units on Vesta.

The groups of students who chose to use the Universe observation tools from ASDC had to replicate the analysis of a couple of exceptional bright flares seen in gamma-rays from the AGILE satellite from the two AGNs PKS 1510-059 and 3C 279. Starting from the AGILE Astronomer's Telegrams (ATels) #6366 and #7631, announcing the dramatic gamma-ray enhancements, they identified the period of AGN activity and searched the correspondent AGILE data from the MMIA Archive. For this special occasion, we provided the students with access to the AGILE LV3 online analysis tool accessible through the ASDC web pages (the tool will soon become public). They very easily familiarized with the tool and, by means of that, they were able to produce a sky map and a light curve of the two sources, showing the rapid increase in gamma-ray flux observed in correspondence of the period reported in the ATels.

At the end of the day, the students compiled a "Daily Log" with all the capabilities acquired during the work.

June 28, 2016 MATISSE on Astrobetter

A post about MATISSE, the ASDC web-tool for the exploitation of planetary exploration data, has been recently published on the Astrobetter blog.
Accordingly to the goal of Astrobetter to give "tips and tricks for professional astronomers", in the aforementioned post the main characteristics of MATISSE have been described together with an example of usage of the tool.
In particular the analysis of the thermal infrared part of the spectrum of asteroid Vesta acquired by VIR instrument aboard NASA Dawn mission has been shown. As these data are publicly available the example can be easily replicated by everyone accessing MATISSE.

May 23, 2016 The 4th Moon Mapping project Workshop

On May 10 and 11 2016 the 4th workshop dedicated to the Italian-Chinese project known as "Moon Mapping" took place at the ASI headquarters in Rome.
The event started with the joined signature of the Intellectual Property agreement by ASI President R. Battiston and COSE vice-president G. Xie.
More than 30 researchers and students from Italy and China involved in the study of the Moon by means of data acquired by instruments onboard the Chinese Chang'e 1 and Chang'e 2 missions participated to the meeting.
The main topics of the joint project (i.e., Map of the solar wind ion, Structure map of the Moon, Map of elements distribution and Establishment of 3D digital visualization system) have been actively discussed together with the presentation of external activities related to the exploration of the Moon and of the Solar System in general.
During the visit to Italy, the Chinese delegation also visited the INFN National Laboratories in Frascati and the facilities of Thales Alenia Space and ALTEC in Turin.

Mar 03, 2016 ASDC contributions to the Italian National Congress on Planetary Sciences

At the 13th Italian National Congress on Planetary Sciences, held in Bormio from 21st to 26th February 2016, the ASDC Solar System Exploration coordinator Angelo Zinzi illustrated the latest upgrades to the ASDC MATISSE tool and presented the Moon Mapping project, an example of successful cooperation between Italy and China, using the data from the Chang'e-1 and Chang'e-2 satellites.

Oct 16, 2015 MATISSE v1.1 now online with major upgrades

A new version of MATISSE (Multi-purpose Advanced Tool for Instruments for the Solar System Exploration) has been released.
The most noticeable features introduced with the version 1.1 now online are:
  • access to public datasets do not require any registration to the tools: just go to the MATISSE homepage and make the query.

  • possibility to access and visualize data from MDIS-NAC camera onboard NASA MESSENGER mission to Mercury. This dataset is archived by PDS and is accessible through the NASA ODE REST API: therefore data do not reside directly in the ASDC storage. This new implementation could be expanded to other missions, instruments and targets on user request.

  • 2 new output formats, better suited for planetary geology studies, are introduced: GeoTIFF and ENVI (IMG+HDR) files, which are now included in the data downloadable from the final page of MATISSE.

  • users belonging to the MoonMapping project can now access Chang'E-2 50 meters per pixel resolution ortophoto maps. In this case the high-resolution 3D visualization for Paraview is created using LOLA 512 ppd (60 m/pixel) elevation maps.
Further info can be found in the user manual.

For any question or suggestion feel free to contact angelo.zinzi@asdc.asi.it
