The 40 cm telescope is a Cassegrain-like configuration, modified to get a short focal length (focal ratio: f/1.8) thus permitting a wide field of view and a good stability on the mount which permits fast LEO objects tracking. The design of optical tube, completely manufactured by students of GAUSS, is shown in the paper. The 30 cm telescope is a Baker-Schmidt (f/2.8). The CCD is equipped with a 4096x4096, 9 μm square, pixels sensor (54 mm diagonal) and will be used for searching campaign and for accurate astrometry measures. The robotic mounts permit full autonomous tracking mode and remote control. The dome has also been designed and manufactured by GAUSS and the design is depicted in the paper, showing solutions adopted in order to achieve transportability and remote control. Whereas the observatory is completely autonomous a large amount of data can be achieved, therefore a lot of efforts have been directed to image processing automation, to screen pictures, separating catalogued targets from uncatalogued ones. The observatory design is described in the paper

Furthermore, there is additional research into what self-reported roadblocks early career students and workers (and employers) consider important in this journey [4]. Academia, employers, schools, colleges, and museums all have considerable roles to play in shaping the future science capital of our populace and establishing people on the tech workforce pipeline. Rising to meet this challenge, The University of Nottingham wants to develop the UK's space workforce and is proud to have begun its first dedicated aerospace undergraduate course in 2016. In addition to the core lecture modules, added project experience is available in the form of group and individual supervised projects. These p...

This problem, arisen in the last 25 years and enhanced in LEO orbit by recent space debris-creation events (ASAT-test of 2007, Iridium33-Cosmos2251 collision of 2009), requires specific strategies to know accurately the orbital debris environment, with the main intent of avoiding collisions between orbital debris and spacecrafts. Since nineties, the Group of Astrodynamics of the University "Sapienza" (GAUSS) of Rome has been involved in optical surveillance of space debris from SpaDE ground based observatory and in UNISAT microsatellite projects (four satellites have been launched from Baykonur cosmodrome in Kazakistan using the Dnepr space launch vehicle). In 2008 GAUSS group started the feasibility study of an UNISAT mission with the aim to identify small LEO space debris with a LEO space based optical system, taking advantage of an observation above Earth's atmosphere. During the last two years,...

This is a concern for future missions and also for future space tourism flights. Nev-ertheless, at the same time it is very interesting to study the effects of these conditions in unhealthy organism like biological samples affected by cancer. It is possible that space envi-ronment increases,

При этом ставится задача отработки алгоритма магнитной ориентации, обеспечивающего одноосную стабилизацию аппарата на Солнце. Подобраны режимы движения макета, позволяющие в наземных условиях провести отработку алгоритма управления. Среди них получена устойчивая прецессия макета и движение, близкое к плоскому. Проведено математическое моделирование движения макета в этих режимах, показывающее возможность его реализации на современном лабораторном оборудовании.

Such motivations demand the tool to be a way not only to assess the TRL condition of operational space missions and systems, but also as a method of evaluating and sharing proposals with new technological content. The TRL methodology and its relation to risk management are discussed. The development phases of the IMATEC Lite application are then described, with emphasis to the data handling structure capable of storing the user product model. A result of technology assessment using the software is detailed by presenting the PBS of the SERPENS 1 mission nanosatellite. The prospects of using the tool for judging the acceptability of new missions and projects are discussed, as well as some of the encountered difficulties.

This mission, entitled Kuaray, was part of the NASA Space Grant Eclipse Ballooning Project, coordinated by the Montana State University, under a partnership with the Brasilia Astronomy Club. The LAICAnSat-5 was launched as secondary payload onto one of the Montana State University BOREALIS Program balloons. The LAICAnSat was the only team from Brazil in the Eclipse Ballooning Project and this paper presents the description of the Kuaray mission, the preliminary test flights conducted at the beginning of 2017, as well as the performance analysis of the newest version of the LAICAnSat platform. Moreover, some key challenges concerning LAICAnSat system development and building were identified and they are related to the platform requirements (elicitation and management), considered as a ke...
