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.

Our Success Stories

Modular, flexible and competitive, the new European launcher is intended to nearly provide the best launch solution to businesses and institutions. As a historical partner of aerospace manufacturers, ALTEN actively participates in their development in various domains (structure, thermal, flight mechanical engineering, etc.).

ALTEN capitalises on more than 25 years of know-how in preparations for the assembly, validation tests and final integration (before launch) of various satellites for CNES and other industrial customers.

To provide very-high-speed internet and customised services worldwide there are projects of constellations (hundreds/thousands of mini-satellites in a low orbit its commissioning soon . ALTEN is also involved on the mechanical design and thermal calculations for these small satellites.

There are many domains of application for Earth observation such as the environment, defence, geology, climatology, telecommunications, and IoT objects. ALTEN supports studies and development of the image processing chains for the satellite observation systems of a major player in the space sector.
