The last two satellites of the Airbus-built, owned and operated Pleiades Neo constellation are on track for launch later this year, following successful final tests in Toulouse’s clean rooms.
Following the seamless parallel integration of both Pleiades Neo 5 and 6 satellites, and the successful conclusion of the environment (thermal vacuum, acoustic, vibration) test campaign, both final spacecraft are now ready to complete the Pleiades Neo constellation.
Both satellites are due to be launched simultaneously on the Vega C European launcher from Kourou, in French Guiana. To tackle this dual launch, the Airbus space engineers came up with a smart and efficient dispenser-free design, where the satellites are stacked on top of each other, linked only by a clamp band.
This compact dispenser-free launch configuration saves volume and mass, as well as reducing cost. Simultaneously testing both satellites in their stacked launch configuration enabled significant time saving, with only four days needed to pass both the three axes Sine testing and the acoustic test.
“With this new bold, dispenser-free design, we were able to seamlessly integrate and test these two very high resolution satellites and ensure an optimised launch configuration: in a single launch, we will double the acquisition capacity of the Pleiades Neo constellation, and offer even greater responsiveness to our customers,” said Philippe Pham, Head of Earth Observation and Science at Airbus.

CACI announces demonstration of optical intersatellite links in low earth orbit
Reston VA (SPX) May 18, 2022
CACI International Inc (NYSE: CACI) reports it has successfully demonstrated space to space optical communications links in low earth orbit (LEO) in partnership with the Defense Advanced Research Projects Agency (DARPA) and the Space Development Agency (SDA) as part of the Mandrake II program.
Mandrake II is a joint risk-reduction program with DARPA, SDA and the Air Force Research Laboratory’s Space Vehicles Directorate (AFRL/RV) to evaluate the pointing, acquisition, and tracking algorithms that … read more
