The Airbus test was carried out in August this year, with the spacecraft touching down in Arizona on September 13.
It was part of a wide campaign of six test flights in total, four of which were low-level flights and two were stratospheric flights.
Each flight lasted about 18 days, adding to a total of 2,435 stratospheric flight hours for Zephyr to date.
Jana Rosenmann, Head of Unmanned Aerial Systems at Airbus, said: “Credible and proven ultra-persistence, stratospheric agility, and payload interoperability underscore why Zephyr is the leader in its sector.
