Oh, would it not be absurd if there was no objective state?
What if the unobserved always waits, insubstantial,
till our eyes give it shape?

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

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.
