On 17 December 2025, two new Galileo satellites lifted off from Europe’s Spaceport in French Guiana. This was the 14th launch for Europe’s satellite navigation operational satellite programme, reinforcing Europe’s resilience and autonomy. The flight, VA266, was the first launch of Galileo satellites on Europe’s newest heavy-lift launcher Ariane 6.
On 14 January 2026, the European Space Agency (ESA) will hold an online post-CM25 industry event for all ESA industrial partners.

Ever wondered how planetary systems like our own Solar System form? Thanks to the European Space Agency’s Gaia space telescope, we're getting a unique peek behind the cosmic curtain into these dusty environments.
It has been a busy year for the European Space Agency’s Proba-3 mission. The satellite duo has already created more than 50 artificial solar eclipses in orbit since the mission operations began less than a year ago. The resulting data confirm Proba-3's ability to provide the missing puzzle piece in our observations of the Sun's enigmatic atmosphere – the corona.
On 17 December, two Galileo satellites lifted off from Europe’s Spaceport in French Guiana aboard an Ariane 6 rocket. This marked the 14th launch for Europe’s Galileo constellation, reinforcing Europe’s satellite navigation capabilities, resilience and autonomy.

Copernicus Sentinel-6B, launched last month, has reached its orbit and delivered its first set of data, which show variations in sea level in the North Atlantic Ocean. This data underlines how the mission will continue to strengthen the long-term reference record of sea levels, a key parameter of climate change.

2025 was a landmark year for Europe in space. From celebrating 50 years of ESA to new missions, scientific breakthroughs, the year reaffirmed Europe’s leadership in science, exploration, climate action and innovation.
Satellites are emerging as a powerful new tool in the fight to curb emissions of methane. While methane is much shorter-lived in the atmosphere than carbon dioxide, it is vastly more potent at trapping heat, which makes rapid cuts essential for slowing warming in the short term. The same satellite technology that has transformed methane monitoring in the oil and gas sector is now being turned towards another major source – landfill sites.
On 17 December, two Galileo satellites will be launched on an Ariane 6 rocket from Europe’s Spaceport in French Guiana in the 14th launch of operational satellites for the Galileo programme. This will be Galileo’s first launch on Ariane 6 and the fifth launch of Europe’s heavy-lift launcher.
