Bringing science to stratosphere
Zephalto has become a key player in the exploration of the stratosphere. In close collaboration with the French space agency (CNES) and the Occitanie region, science is on board for every journey: each manned flight represents a unique opportunity to collect essential data to understand the atmosphere, monitor climate change, or observe Earth and Space. By paving the way for regular measurements in the stratosphere, Zephalto makes a significant contribution to research and provides unprecedented conditions for conducting numerous tests at very high altitudes.
