The spacecraft took off, destined for the Earth’s high orbit, from the Satish Dhawan Space Center in India at 11:34 a.m. CET on Thursday.
The launch was part of the European Space Agency's (ESA) Proba-3 project, which will gather information about the Sun's outer atmosphere, the corona.
The ESA’s mission involves testing new technologies for autonomous, self-guiding spacecraft, which will fly in formation to conduct the research.
Filip Perczyński from Sener Polska, the main Polish contractor for the venture, told the newspaper Rzeczpospolita that the mission is to show an “important direction in the future of space research.”
“Thanks to such technology, it will be possible to reduce costs compared to the construction of large, single research satellites,” he said.
“In the future, satellite formations will be used in research missions to observe distant planets or dynamic phenomena in the galaxy.”
During the mission, the two small spacecraft will fly in formation, staying just 150 meters apart and precisely aligning with each other.
They are meant to work together to act like a giant solar observatory, with one craft blocking the Sun’s light and the other studying the corona, which is hard to observe from Earth because of the Sun's brightness.
Sener Polska’s contribution to the project involved developing mechanisms for securing and deploying the satellites’ solar panels, along with technologies enabling the correct positioning of research instruments.
Other companies and institutions from the Polish space engineering sector are also involved.
The Space Research Centre of the Polish Academy of Sciences has developed components for some of the mission’s research tools, and firms such as Creotech Instruments, Astri Polska, GMV, Solaris Optics, PCO and N7 Space have also played a role.
“Polish specialists made a significant contribution both to the preparation of mechanical components and to the creation of advanced research instruments,” Filip Perczyński said.
“It highlights Poland’s growing position in the European space sector.”
