In an exciting development, Estonia's fourth satellite, ESTCube-2, was launched into space from French Guiana on Monday at 4:36 a.m. Estonian time. Originally scheduled for October 7, the launch faced a brief delay just moments before liftoff.
Hans Teras, junior research fellow at the University of Tartu Observatory and ESTCube-2 project manager, expressed pride in the team's achievement after years of dedicated effort. However, he emphasized that the work is far from over, as ongoing efforts are needed to manage and conduct scientific experiments with the orbiting satellite.
Controlling a satellite, noted ESTCube-2's leading systems engineer Kristo Allaje, is a complex task, often surpassing the challenges of building one. The satellite's operational lifetime is slated for two years, underscoring the importance of timely and precise operations.
ESTCube-2, a three-unit CubeSat, is approximately the size of a shoebox, comprising three 10 × 10 × 10 cm cubes and weighing a total of 4.5 kg. The satellite represents Estonia's most research-intensive space venture and has seen significant contributions from approximately 600 students, predominantly from the University of Tartu.
The primary mission of ESTCube-2 is to address space debris reduction, showcasing the nation's commitment to sustainable space practices. Additionally, the satellite carries out an anti-corrosion experiment, Earth observation through integrated cameras, and testing of a groundbreaking cybersecurity system developed by CybExer Technologies OÜ to bolster resilience against cyber threats. The satellite's plasma brake function serves to deorbit the satellite at the conclusion of its mission.
A decade after the launch of ESTCube-1, which marked Estonia's foray into space exploration, ESTCube-2 stands as a testament to the nation's continued progress and dedication in the field. This mission was a collaborative effort involving the Estonian Student Satellite Foundation, partners from Finland and Germany, and received support from the European Space Agency and the European Union.
