CTLearn is a package under active development that pursues the application of deep-learning based methods to the analysis of data from imaging atmospheric Cherenkov telescopes (IACTs). CTLearn includes modules for loading and manipulating IACT data and for running machine learning models using pixel-wise camera data as input. Its high-level interface provides a configuration-file-based workflow to drive reproducible training and prediction.

Casacore is a suite of C++ libraries for radio astronomy data processing. Casacore underlies CASA, the Common Astronomy Software Applications developed by an international consortium of scientists at various institutes. Python bindings exist in Python-casacore. Casacore also underlies other radio astronomy software such as WSClean, and LOFAR tools. Casacore is developed by the radio astro organizations around the world. It is open source and will happily merge any (good) pull requests.

COIN (COsmostatistics INitiative) is an international working group built under the auspices of the International Astrostatistics Association (IAA). It aims to create an interdisciplinary environment where collaborations between astronomers, statisticians and machine learning experts can flourish. COIN is designed to promote the development of a new family of tools for data exploration in astrophysics and cosmology.

GNU Astronomy Utilities (Gnuastro) is an official GNU package consisting of many command-line programs and library functions for the manipulation and analysis of astronomical data. All the programs share the same basic and familiar (GNU style) command-line user interface for the comfort of both the users and developers. Gnuastro is written to comply fully with the GNU coding standards so it blends nicely with all Unix-like operating systems. This also enables astronomers to expect a fully familiar experience in the source code, building, installing and command-line user interaction. Gnuastro also has a very complete book/manual, the tutorials is the best place to start using it.

The Italian Mars Society (IMS) is a non-profit organization, existing from 2004, as Italian branch of the International Mars Society, created in the USA by Robert Zubrin. IMS is a member of the Mars Society European network. The foundation scope of the Italian Mars Society is to promote research projects devoted to Mars Exploration and the involvement of SMEs and large enterprises in the new economy related to space exploration.
IMS is currently spearheading the MARS CITY project. The project aims to address the major issues that could jeopardize a crewed mission to Mars and are not adequately being addressed at existing terrestrial Mars analogs.
