European Space Agency Mission “Comet Interceptor” Applies Comet Models Developed in Latvia

May 20, 2025

Through collaboration between Latvian technology company Nanocraft SIA, Ventspils University of Applied Sciences, and the Tartu Observatory, the photo-realistic modelling project “CI3D” has been successfully delivered to the European Space Agency (ESA). The project activities have produced computer-generated images used for testing the cameras of ESA’s “Comet Interceptor” mission. Since the mission, scheduled for the early 2030s, will approach a still-unknown target comet—its trajectory from the Oort cloud towards the Sun currently too distant to observe with telescopes—photo-realistic images are needed to validate the mission’s cameras.

Just like in the production of the film Straume, the “CI3D” team uses the photorealistic 3D modelling tool Blender. Both internationally recognized projects share a common theme—the teams are capable of producing virtual worlds that expand our imagination. All space missions developed so far have been aimed at specific known targets—objects or phenomena in the Universe. Following the impressive achievements of Rosetta, ESA has taken on an entirely new space technology challenge—developing a mission involving multiple probes that will approach a target comet that may still be unknown even at the time of spacecraft launch. Thus, the “Comet Interceptor” mission demonstrates Europe’s leadership in cometary research.

New challenges make science and technology projects exciting. The Latvian–Estonian team has carved out a special niche since the late 2010s, when under the leadership of Professor Mihkel Pajusalu at the Tartu Observatory, Dr. Andris Slavinskis and colleagues began mastering the Blender tool. After a decade spent in Sweden, Switzerland, Estonia, the USA, and Finland, Slavinskis returned to Latvia with the idea to found a company focused specifically on space scene modelling. To tackle complex problems in comet atmosphere modelling, Slavinskis turned to scientists at his alma mater — Ventspils University of Applied Sciences—Professor Andris Vaivads and researcher Karina Šķirmante.

Successful space camera development requires comprehensive knowledge of the physical parameters that characterize the mission target. In the “Comet Interceptor” mission, we must model a range of physical parameters to represent various possible comet sizes, shapes, activity levels, as well as fly-by speed and geometry (the probe’s orientation relative to the comet and the direction of incoming sunlight). Additionally, as part of the delivered project, the “CI3D” team worked with three cameras—“OPIC”, “MIRMIS NIR”, and “EnVisS”—which are being developed in Estonia, Finland, and Italy, respectively. The “Comet Interceptor” mission comprises three probes: the main spacecraft “A”, which carries the “MIRMIS NIR” camera; probe “B2”, which carries “OPIC” and “EnVisS”; and probe “B1”. The Blender modelling tool allows virtual programming of physical and fly-by parameters.

 

With the successful delivery of the project, the “CI3D” team is preparing for future activities. During the project extension, the comet atmosphere model will be enhanced with a tail and jets, and background stars will be added to assist in determining the orientation of probe “B2”. The extension also includes plans to interview the remaining five “Comet Interceptor” camera teams whose instruments are installed on all three probes. Probe “B1” is being developed by the Japan Aerospace Exploration Agency, offering the Latvian computer science team an opportunity to expand cooperation beyond Europe.

At 7 AM on the 24th September an airplane took off to fly to Brussels. It was a quiet morning, the air was charged with excitement and sleep deprivation, when seven 4TLT students, along with lecturer Zane France arrived at their destination, where they were welcomed by European Parliament’s vice-presidents’ assistant Guna Zaķe-Baltā. VUAS students had the opportunity to get lost in the ‘labyrinth’ of the European Parliament, attend a lecture about the work of both the European Parliament and its members, as well as get a glimpse into the history of the establishment. The students could learn about how actively (or not) Latvia participates in voting, how much ‘pocket money’ do members get, what is the monthly schedule and how often do the meetings happen in Brussels and Strasbourg. After the lecture the excursion continued, and the students saw a part of the enormous building of the Parliament (one can wonder, do the new hires get a compass and a map?), the famous conference room, gifts of the countries of the European Union (including artworks gifted by Latvia), and even the cabinet of Roberts Zīle (where the guests were greeted by sandwiches, apples, and chocolate :) ). The cherry on top was the opportunity to meet with the European Parliament’s interpreters Dace Rubene and Ilze Lauva, and the Head of the Latvian unit of Directorate-General of the European Commission Uldis Sproģis and talk about how many languages interpreters usually know, how does interpreting differ in the European Commission and European Parliament, what is retour, and what should one do if the speaker’s tempo is too fast, as well as if voice matters in interpreting. At the end, the students had the opportunity to try interpreting in the Conference Interpretation Booths (with the microphone, hopefully, turned off!) and interpret the conference about the safety of minors on the internet. It was a wonderful experience that allowed the students to learn about the professionalism of the interpreters and working in the Parliament, as well as internship opportunities and how difficult it is to become an interpreter in the European Parliament. In the evening and on the next day, the students were given free rein to taste Belgian chocolate, see the Peeing boy statue and ponder on whether to come back and work in the Parliament. Impressions of the participants: “Although I have never thought that conference interpreting is easy, this tour highlighted how difficult and challenging it actually is and what enormous wealth of background knowledge interpreters need to have.” “I really enjoyed the trip! At first, I wasn't too sure whether to participate, but I’m happy that I mustered up my courage and decided to go. I can definitely say that visiting the European Parliament is a wonderful opportunity, and that it was very interesting to learn about the work and experiences of the interpreters.” “I will definitely remember the visit to the European Parliament for an eternity, but the meeting with the interpreters that work there is what left the most significant impression. For a while I thought that they’re some kind of superheroes – which they definitely are – but after the meeting I realised that they are people just like us. Thanks to them, work in the European Parliament has turned from something intangible into a real possibility you can achieve by investing a lot of hard work.”

Approximately 700 million Europeans are constantly encouraged throughout their lives to learn as many languages as possible – whether in educational institutions, through self-study, for professional purposes, or out of personal interest. The Council of Europe states that multilingualism is a means to foster better intercultural understanding and is a key component of our continent’s cultural heritage. Representatives from the language centres of the COLOURS European Universities Alliance* joined forces in a collaborative project, creating a video greeting in honour of the European Day of Languages, celebrated annually on September 26. Ventspils University of Applied Sciences is represented in this team by Rūta Maltisova, lecturer at the Faculty of Translation Studies, who also took part in the creation of the video greeting. Rūta is currently working together with colleagues from all COLOURS partner universities on a virtual language and culture guide – a glossary and language learning materials – which are planned to be developed and made available to all partner universities by the European Day of Languages in 2026. This initiative aims to support students and lecturers in learning and teaching nine European languages and cultures: Swedish, Spanish, French, Italian, German, Latvian, Polish, Croatian, and Macedonian. At the end of the video, greetings can be heard in each of the COLOURS alliance member languages, all translating into English as “Happy European Day of Languages!” or in Latvian, “Priecīgu Eiropas valodu dienu!” On the European Day of Languages, Rūta Maltisova encourages everyone to remember that languages are like bridges connecting different cultures. Without them, we would only be able to observe each other from a safe distance, separated by a potential barrier of prejudice that prevents us from understanding the essence and values of another culture. By learning a language, we also learn about the culture – and, in doing so, we learn about one another. Thanks to the COLOURS Universities Alliance, we learn something new every day about each other’s cultures, values, and, undoubtedly, languages. *Le Mans University (France), University of Castilla-La Mancha (Spain), University of Ferrara (Italy), Paderborn University (Germany), Jan Dlugosz University (Poland), Josip Juraj Strossmayer University of Osijek (Croatia), University St Kliment Ohridski Bitola (North Macedonia), Kristianstad University (Sweden), and Ventspils University of Applied Sciences (Latvia).
