Four Tartu Observatory employees were awarded honorary decorations of the University of Tartu

Mare Ruusalepp

University of Tartu has announced this year's recipients of its honorary decorations. Head of MTÜ Stellaarium Mare Ruusalepp was awarded the Star of Appreciation and Tartu Observatory's Lead Engineer Viljo Allik, Associate Professor in Stellar Physics Anna Aret and Senior Engineer Enno Ruusalepp are recipients of the Badge of Distinction.

Mare Ruusalepp is a long-time head of research and has also led the information group at Tartu Observatory. Besides that, she has been the director of the observatory's visitor centre and is now the head of MTÜ Stellaarium. Founding the first visitor centre – the Stellaarium located at our telescope tower – can also be considered Ruusalepp's greatest contribution to Tartu Observatory. After Stellaarium was founded in 1997, Ruusalepp took it upon herself to make sure its rooms are filled with educational materials, and has been keeping it operating ever since.

Before the pandemic, Stellaarium's astronomy-themed exhibitions and attractions, including the 270 kg meteorite, were annually visited by circa 230 groups with about 5000 people, 85% of them school children. In 2008, MTÜ Stellaarium won the first prize at the Estonian science popularisation awards, and in 2015, Mare Ruusalepp was awarded the Life Achievement Award.

 

 

Viljo Allik has been working at Tartu Observatory since 2010, first as a research fellow and now as lead engineer. His technical consultation skills and contributions to the development of satellite electronics as well as Tartu Observatory's laboratory complex and satellite ground station have been invaluable.

Allik was responsible for gaining and maintaining communication with the first Estonian satellite ESTCube-1, but he is also the one to thank for attaining communication with the European Student Earth Orbiter ESEO and satellites Koit and Hämarik of TalTech. Renowned technology companies who Tartu Observatory's laboratories have had as clients have also praised Viljo for his excellent technical consultations and keep returning to Tõravere. Besides that, Viljo dedicates his personal time, energy and equipment to creating photo and video materials of and for Tartu Observatory's events and projects.

 

 

Anna Aret started working at Tartu Observatory (then Institute of Astrophysics and Atmospheric Physics) in 1989 as a junior research fellow. Since that, Aret has been a research fellow, senior research fellow, and now associate professor and the head of the stellar physics department. As a leader, Aret is enthusiastic and inspiring. It is worth highlighting that under her coordination, Tartu Observatory started to implement its telescopes into many international cooperation projects. One of the biggest examples is the European Space Agency's exoplanet mission Ariel which includes pre-launch observations in Tõravere.

Aret is a distinguished researcher of her field in both Estonia and abroad, being a member of many national and international networks and associations. Her contributions include being an Estonian representative in the Europlanet Society and a peer reviewer for The Astrophysical Journal.

 

 

Enno Ruusalepp has been working at Tartu Observatory for 52 years. A strong basis in engineering from the Leningrad Institute of Fine Mechanics and Optics allowed him to contribute to the development of telescopes and other equipment in Tõravere from a young age. He has built, modernised and renovated many photometers, spectrophotometers and spectrographs. The 1.5 metre telescope, which is the largest one in  Tõravere and the Nordic countries in general, has been under his care since it was built.

In 1992, Ruusalepp became the administrative director of Tartu Observatory. His responsibilities included the science park's electricity and water supply, access roads, administration contracts, and more. After Tartu Observatory merged with the University of Tartu in 2018, Ruusalepp quickly gained fame among others in his field as an admirably capable administrator who always kept everything in his scope in perfect order. Regarding his age, Ruusalepp has been working in his original field as a telescope engineer since 2020.
