Using ESA’s XMM-Newton and NASA’s Chandra X-ray space telescopes, astronomers have made an important step in the quest to find a planet outside of the Milky Way.

The 72nd International Astronautical Congress opens its doors on Monday 25 October at the Dubai  World Trade Centre in the United Arab Emirates, for a week of intense interactions for the world space community. After one year online due to COVID-19 restrictions, the congress returns to an in-person event with the theme 'Inspire, innovate and discover for the benefit of humankind'.

German ESA astronaut Matthias Maurer will soon begin his first mission to the International Space Station. As a member of Crew-3, he will be launched from NASA’s Kennedy Space Center in a SpaceX Crew Dragon spacecraft alongside NASA astronauts Raja Chari, Tom Marshburn and Kayla Barron.

Europe’s Ariane 5 has delivered two telecom satellites, SES-17 and Syracuse-4A, into their planned orbits.

On this day, twenty years ago, ESA’s first small satellite, Proba-1 (Project for On Board Autonomy), was launched with just one goal – to prove technologies in space.

When considering the implications of thawing permafrost, our initial worries are likely to turn to the major issue of methane being released into the atmosphere and exacerbating global warming or issues for local communities as the ground and infrastructure become unstable. While this is bad enough, new research reveals that the potential effects of permafrost thaw could also pose serious health threats.

Earth observation provides a wealth of information to benefit our daily lives. As the demand for satellite data grows to address the challenges of climate change and a growing population, ESA, under the leadership of the European Commission, along with its key European partners, are developing high precision digital models of Earth to monitor and simulate both natural and human activity, to enable more sustainable development and support European environmental policies.

Europe’s own satellite navigation system, Galileo, has become the world’s most precise, delivering metre-level accuracy, available anywhere on Earth. It is also saving lives, relaying distress calls for search and rescue. Today there are 26 Galileo satellites in orbit 23 222 km over our heads; the first of them were launched on 21 October 2011, with nine more launches in the following years. The satellites in space are supported by a globe-spanning ground segment. The system as a whole is set to grow, with the first of 12 ‘Batch 3’ about to join the current satellites in orbit and new ‘Galileo Second Generation’ satellites in development.

ESA Vision: accelerate the use of space

On 21 October 2011, the first pair of Galileo navigation satellites was launched by a Russian-built Soyuz rocket from Europe’s Spaceport in French Guiana.

As of today, ESA has appointed three new Directors - for Commercialisation, Industry and Procurement, Earth Observation Programmes and Navigation. The new Directors were appointed by ESA Council at its meeting on 21 October; they will support the Director General with responsibility for activities and overall objectives in their respective directorates.

While the climate crisis is, unfortunately, a reality, it is all too easy to assume that every aspect of our changing world is a consequence of climate change. Assumptions play no role in key environmental assessments and mitigation strategies such as we will see in the upcoming UN climate change COP-26 conference – it’s the science and hard facts that are critical. New research published this week is a prime example of facts that matter. Using model projections combined with satellite data from ESA’s Climate Change Initiative, this latest research shows that the global rise in the temperature of lake water and dwindling lake-ice cover can only be explained by the increase in greenhouse gas emissions since the industrial revolution – in other words, humans are clearly to blame. 

ESA Impact October Council edition

On 22 September, around midday, ESA’s Integral spacecraft went into emergency Safe Mode. One of the spacecraft’s three active ‘reaction wheels’ had turned off without warning and stopped spinning, causing a ripple effect that meant the satellite itself began to rotate.
