Marking the first public day of this year’s International Paris Air Show, the President of France Emmanuel Macron visited the Paris Space Hub.  

ESA Director General Josef Aschbacher and Director of Human and Robotic Exploration Daniel Neuenschwander welcomed President Macron, introducing him to the assembled French astronauts and a group of young space professionals in attendance.  

French ESA astronaut Sophie Adenot joined by video link from the United States, where she is training for her upcoming mission to the International Space Station. Sophie detailed some of her training, explaining that no two days are alike. Fellow astronauts Thomas Pesquet, Jean-François Clervoy and Claudie Haignéré also addressed Sophie and offered their advice for her time in space. Together President Macron and Sophie announced that her mission will be named εpsilon, and revealed her mission patch.

Speaking about the development of the space industry, President Macron said Europe must increase investment in commercial space, and emphasised the importance of complementarity of public and private investment – particularly with the upcoming ESA Council at Ministerial level and ongoing discussions for the next EU multiannual financial framework. He also mentioned the developing need for dual-use space capacity including surveillance. President Macron highlighted the importance of research and of making Europe a destination for researchers in line with the EU Choose Europe for Science initiative. He also called on Europe to improve its competitiveness in space. Watch a replay of the visit.  

A new Letter of Intent between the European Space Agency and Dassault Aviation was also announced, signalling the common interest of the organisations in working on low Earth orbit exploration, in particular orbital vehicles.

εpsilon: Sophie Adenot’s first mission name and patch unveiled

ESO Top News - Fri, 06/20/2025 - 8:00am
Image:

ESA astronaut Sophie Adenot’s first mission to the International Space Station now has a name: εpsilon. The mission name and patch were announced today at the Paris Air Show by ESA Director General Josef Aschbacher, French President Emmanuel Macron, and Sophie Adenot, who joined remotely from the United States, where she is training for her spaceflight.

Sophie Adenot is one of the five astronauts selected from ESA’s most recent astronaut class of 2022. Following the successful completion of their basic training in spring 2024, Josef Aschbacher announced during the Space Council in Brussels that Sophie and fellow graduate Raphaël Liégois had been assigned their first missions to the International Space Station, currently planned for 2026.

The εpsilon name and patch reflect the power of small, yet impactful contributions and how multiple parts unite to create a whole.

In mathematics, “ε” represents something small. In the extensive collaborative effort of space exploration, involving thousands of participants, all roles, including the astronaut's role, stay small yet meaningful.

The hummingbird, central to the patch, embodies this idea; though one of Earth’s smallest birds, it plays a crucial role in the jungle’s ecosystem, pollinating numerous plants.

Encircling the patch is a ring of small dots, symbolising the many small contributions that together make great achievements possible. All these little actions that can be coordinated to form a circle and close the loop. At the top, three of these dots are coloured – blue, white, and red – representing Sophie’s home country, France, and ESA’s exploration destinations: Earth, the Moon, and Mars.

The name εpsilon, being the fifth Greek letter and the fifth brightest star of the Leo constellation, also follows the French tradition to name human spaceflight missions after celestial bodies. It also pays tribute to the five career astronauts of ESA’s 2022 class. 

Three lines emerge from the “i” of the εpsilon, shaping the tail of a shooting star, a poetic reminder that dreams keep us alive.

At the base of the patch lies a rounded blue shape, representing Earth’s surface and its natural beauty: mountains, forests and landscapes that Sophie enjoys exploring. It serves as a reminder of our motivation for spaceflight: to explore, learn, and return with this knowledge to benefit life on Earth.

From an emotional perspective, the same message is conveyed. In life's intricate tapestry, small threads contribute to create the most beautiful patterns. A kind word, a gentle smile, a moment of patience - these seemingly insignificant actions can transform lives and shape destinies. This patch invites each of us to embrace the potential of our smallest actions as they ripple outward, touching hearts and inspiring souls.

During her εpsilon mission, Sophie will perform numerous scientific experiments, many of them European, conduct medical research, support Earth observation and contribute to operations and maintenance aboard the International Space Station.

Webb Shows That Young Stars Inherit Their Water From the Cosmos

Universe Today - Fri, 06/20/2025 - 6:21am

The early Solar System was filled with both hydrogen and oxygen that can chemically bond into water. But did we create all the water, or was some of it inherited from the earlier times, already present in the protostellar nebula? Astronomers have used the James Webb Space Telescope to study a newly-forming protoplanetary system called L1527 IRS, which will eventually become a star like our Sun. They found evidence that water from interstellar space is preserved when it becomes part of a new star system.

Have Stellar Flybys Altered Earth's Climate in the Past?

Universe Today - Fri, 06/20/2025 - 6:21am

If our Solar System seems stable, it's because our short lifespans make it seem that way. Earth revolves, night follows day, the Moon moves through light and shadow, and the Sun hangs in the sky. But in reality, everything is moving and influencing everything else, and the fine balance we observe can easily be disrupted. Could passing stars have disrupted Earth's orbit and ushered in dramatic climatic changes in our planet's past?

Astronomers are Closing in on the Source of Galactic Cosmic Rays

Universe Today - Fri, 06/20/2025 - 6:21am

In 1912, astronomer Victor Hess discovered strange, high-energy particles called "cosmic rays." Since then, researchers have hunted for their birthplaces. Today, we know about some of the cosmic ray "launch pads", ranging from the Sun and supernova explosions to black holes and distant active galactic nuclei. What astronomers are now searching are sources of cosmic rays within the Milky Way Galaxy. One such source is a pulsar wind nebula sending high-energy particles out to space.
