Space exploration is one of humanity’s most exciting and daring endeavors. Since Galilee’s use of the telescope in the 17th century to the recent SpaceX human space flights, space has captivated the imagination of people around the world.

With new technologies and innovations, the possibilities for exploration are endless, and the potential for discovery is boundless.

Private sector flies into space

The private sector’s enthusiasm for space continues to boost the sector and will democratise new applications (space travel, satellite imagery, internet via satellite, data processing, Internet of Things (IoT), etc.). The current geopolitical context triggers new developments and innovations regarding the space defense strategy.

After the success of the American New Space (Space X, Blue Origin, etc.), it is now Europe’s turn to encourage the development of the private sector. Partnerships are increasing between the ESA and traditional industries companies and start‑ups.

In the same time, the space industry is accompanying states in the protection of the cosmos and space assets, through new technologies and cybersecurity.
