ViaSat-3 Satellite Completes Mechanical Environmental Testing

Satellite receives green light to move ahead, closer to launch

The first of three ViaSat-3 satellites at the Boeing factory in El Segundo, Calif., completing vibration tests, one of the milestones that qualify a spacecraft for the rigors of launch and harshness of space. The spacecraft also completed acoustic (sound) and thermal vacuum (temperature and vacuum extremes) testing.

CARLSBAD., Calif., October 11, 2022 -- Viasat Inc. (NASDAQ: VSAT), a global leader in satellite communications, announced today the ViaSat-3 Americas satellite has completed mechanical environmental testing. This is a significant milestone that is designed to verify the satellite can endure the rigors of launch and continues the momentum for launch later this year.

During mechanical environmental testing, the ViaSat-3 Americas satellite was subjected to simulations of the vibration and acoustic environments it will experience during launch. The satellite had already successfully completed thermal vacuum testing that simulated vacuum and extreme hot and cold conditions of space where the satellite will operate during its expected 15-year lifetime.

“The completion of the mechanical environmental testing, coupled with the earlier successful completion of thermal vacuum testing, confirms that the first ViaSat-3 spacecraft can withstand the extreme environments from launch through in-orbit operations,” said Dave Ryan, president of Space & Commercial Networks at Viasat. “The combined Viasat, Boeing, and Northrop Grumman teams have done an outstanding job in progressing through environmental testing with very successful results.”

The ViaSat-3 Americas satellite now moves into post-environmental deployment testing, where the solar arrays, reflectors, radiators and thrusters are tested to ensure they can survive launch conditions and properly deploy on orbit.

The ViaSat-3 class of Ka-band satellites are expected to provide the best bandwidth economics in the industry with substantial flexibility to move and concentrate that capacity virtually anywhere there is demand - whether it is on land, in the ocean or in the air. The first two satellites are planned to focus on the Americas and on EMEA, respectively, and the ViaSat-3 EMEA satellite is undergoing integration with spacecraft partner, Boeing. The third ViaSat-3 satellite is now undergoing final payload integration and testing at Viasat’s Tempe, Arizona facility and will focus on the Asia Pacific region, completing Viasat’s global service coverage.
