VIRAC researcher will give a lecture at the Astronomy School

October 9, 2024

On 11 October, a hybrid lecture "Astronomy School" is planned at Liepāja Rainis Secondary School in room 124 or remotely in MS Teams


Topic: The European Space Agency's JUICE (Jupiter's Icy Moons Exploration Mission): First Year in Space"


Lecturer: Vladislav Bezrukov, Researcher, Ventspils International Radio Astronomy Centre (VIRAC)"


Lecture information:

*ESA JUICE - PRIDE experiment.


*JUICE (JUpiter ICy moons Explorer) is ESA's large-class science mission, launched in April 2023 and expected to reach the Jupiter system in 2030. JUICE's main goal is to explore the habitable zone around Jupiter, including its icy moons. Ganymede is a priority object that offers unique opportunities to analyse the nature and evolution of the icy world, including the properties of subglacial oceans. The study of Europa's moon will focus on recently active areas, while Callisto will be studied as a witness to the early solar system. The mission includes scientific studies using 11 instruments on the spacecraft as well as the ground-based radio astronomy experiment PRIDE.


VIRAC participates in the radio astronomy component of the JUICE mission, the Planetary Radio Interferometry and Doppler Experiment (PRIDE). The principle of PRIDE is the observation of spacecraft radio signals using a network of Earth-based radio telescopes with VLBI (Very Long Baseline Interferometry) technology. The main PRIDE measurements are the spacecraft coordinates and radial velocity. These data help to improve the ephemeris of the Jupiter system and support the interdisciplinary scientific research of the JUICE Mission.

On 10 December, the VUAS Library invited students to a meeting with Rafael Martín Calvo, Assistant Professor at the Faculty of Translation Studies. He talked about how a writer's work is presented to publishers in another country before it is translated, what to do when only a few Latvians know a certain Latvian word, how many hours it takes to translate a novel and when is the best time to learn a foreign language. He also talked about participation in publishers' events, book fairs and book presentations in different countries. The students also had the opportunity to see translations of Nora Ikstena, Albert Bell, Guntis Berelis and other writers already published and to learn more about each of them. R. Martin Calvo also talked about his dream projects and revealed some of the works he is currently involved in. Thank you to the VUAS Library for hosting the event!

On 3 and 4 of December, the European Parliament's service hosted the third edition of the Citizens' Language Days, a two-day event dedicated to exploring the power of clear language in fostering transparency and democratic participation. The event, organised in Luxembourg, was also attended by students from the translation programmes of the universities included in the EMT (European Master in Translation) network. One student represented each EU language. Latvia and the Latvian language were represented by Adrija Enrika Ēdele, a student of the Master's programme in Translation at VUAS. The students were invited to the European Parliament (EP) in Luxembourg, where most of the staff of the EP Directorate-General for Translation work. In addition to workshops and conferences, the students had the opportunity to get to know the quarter where the European Parliament is located and the work of DG Translation. "During the event, we were able to listen to conferences, workshops and speeches in different EU languages. It was particularly important that we were present at the presentation of the Citizens' Language Guidelines, which are an important tool for language professionals, translators and others interested in the production and adaptation of texts into plain language," says Adrija. It should be noted that the guidelines are derived from the ISO standard on plain language. The guidelines are available in all 24 EU languages and include not only text, but also video and audio material.

On 22 November, the European Commission organised a virtual visit to the Directorate-General for Translation, which was also attended by MA students of the Faculty of Translation Studies of the VUAS. The event was well attended (around 800 participants) and gave our translation students the opportunity to learn all about the work of translators and interpreters in DG Translation and other EU institutions. The event organisers gave an overview of the volume of documents translated in the EU institutions and explained the computer-aided, machine translation and artificial intelligence tools used by translators in the EU institutions. Our students had a one-to-one meeting with translators from the Latvian Translation Unit, where they could get answers to all their questions about eligibility requirements, application prerequisites and how to apply for a traineeship or a job in the EU institution.

In anticipation of the lighting of the Christmas tree, Ventspils has implemented an idea that combines technology and Christmas traditions. An online project has been created - the website "Lantern Fever", where everyone can take part in decorating the Christmas tree using game elements. The project is a collaboration between the Faculty of Information Technologies of VUAS and the Ventspils Culture Centre. The game will be available for a week and will end on 30 November, when the lighting of the Main Christmas Tree will take place in Ventspils' Grand Place. The culminating event will light up the game, the city's Christmas decorations and the Christmas tree. "This game is a prototype and my first full project, which I developed from A to Z," says the game's developer, Aleksis Grečuhins, a student at the Faculty of Information Technologies at VUAS. "It was an intense and challenging work, which helped me to develop my programming skills and to understand how to cooperate with a client and how to adapt to their vision." The project also serves as a study - an attempt to find out if it is possible to create a Christmas mood through a game. Aleksis is especially grateful to Karina Skirmante, lecturer at the Faculty of Information Technology, for her professional support and the sprint reporting system, which helped to move the work forward efficiently.
