Slovenia: First Slovenian satellites reache space

Following a number of cancellations due to poor weather conditions, the launch of Slovenia’s first satellites, Trisat and Nemo HD, as part of a project by European space company Arianespace, was successfully executed this morning.

Arianespace’s Vega rocket, which carried a record 53 satellites from 13 countries, was successfully launched from French Guiana at 3:51 am CET.

Both Slovenian satellites, which constitute an important milestone for the country’s as well as Europe’s space technology efforts, have already been placed in the orbit, with Nemo HD circulating at 515 kilometres and Trisat at 530 kilometres above Earth.

Their first contacts with stations in Ljubljana and Maribor are expected to be established at 10:43 am and 10:50 am respectively.

The head of the Trisat project Iztok Kramberger of the Maribor Faculty of Electrical Engineering and Computer Science told the STA a group of researchers had gathered at the faculty to follow the launch that had gone very smoothly.

“We’re happy that this first hurdle has been overcome. Bu the real work has barely started, we’re only at the beginning”, Kramberger said regarding the 4.4-kilo nanosatellite capable of capturing multispectral images of Earth in short-wave infrared spectrum with a state-of-the-art space camera.

It will primarily bring insights into how robust this new space technology is, while its images could help monitor situations like sea pollution with oil stains or plastics, major fires or volcanic ash in the atmosphere for the needs of the aviation industry.

The Nemo HD is a 65-kilo micro-satellite, which will be producing panchromatic and multispectral images and will be able to do so in an interactive fashion.

It was developed by the Ljubljana-based Centre of Excellence for Space Sciences and Technologies (SPACE-SI) and will for instance help monitor the Earth for agricultural, forestry, urbanistic and maritime transport purposes.

The Slovenian satellites are part of the first test of the Small Spacecraft Mission Service (SSMS) concept, which will allow a larger number of satellites to be deployed in one go, meaning at a smaller cost.

Kramberger appeared positive that Slovenia had focused on the right size and technology and had “caught the right development wave”.

SPACE-SI head Tomaž Rodič agrees: “It is above all a confirmation that our development strategy in the field of micro-satellites, drawn up over a decade ago, was right and allowed us to be part of a pioneering mission of the European Space Agency”.

In a similar vein, Amsterdam-based Slovenian astrophysicist Jure Japelj stresses that Trisat was built almost exclusively in Slovenia.

“Foreigners can notice this and in time this leads to bigger projects”, said Japelj, while explaining the primary focus of the two satellites would for now be the testing of new technologies.

Minister of Economic Development and Technology Zdravko Počivalšek also commented on this important milestone, as he tweeted that “Slovenia has joined the group of countries with operative satellites in space, a top achievement that should make us extremely proud”. /ibna
