Proba-3's first autonomous formation flight

ARHIVEERITUD SISU 27 MÄRTS. 2025 Avaldamiskuupäev 5277 Vaatamised

Two spacecraft flying as one – that is the goal of European Space Agency’s Proba-3 mission. Earlier this week, the eclipse-maker moved a step closer to achieving that goal, as both spacecraft aligned with the Sun, maintaining their relative position for several hours without any control from the ground.


Esther comments: “An endeavour like this brings together people from different areas of expertise. Systems engineers, flight dynamics engineers, spacecraft operators and subsystem experts all meet here in the control room to work together towards a common goal – to make ESA’s first autonomous precise formation flight happen. It’s a great privilege to be a part of it, witnessing two decades of efforts finally coming to fruition.”

Through In-Orbit Demonstration experiments, the General Support Technology Programme (GSTP) enables ESA to pioneer new technologies. Many of these demonstration missions have launched recently or are due to launch in the coming years, like the Agency’s first standalone deep space CubeSat HENON or the LUMIO CubeSat that will explore meteoroid impacts on the far side of the Moon.

“It is the combination of all these instruments and software working together that make Proba-3 unique. A decade ago, none of these technologies were available – now we are about to accomplish what no one has before, enabling many more ambitious missions to come.”
