The vibration testing conducted at Experior Laboratories exposed the Vigoride spacecraft to the forces and environmental factors it may experience during launch.

"Vibration testing is a significant milestone in the ground test campaigns we do in preparation for our missions,” said Momentus Chief Executive Officer John Rood. “This particular vehicle that completed vibration testing is the latest block of our Orbital Service Vehicle and features increased payload capacity and improved payload environments, as well as some other upgrades to implement what we learned from our first demonstration mission.”

The December flight will mark Momentus’ second demonstration mission. The vehicle will carry payloads for customers Caltech and Qosmosys. In addition to deploying customer payloads, Momentus will aim to comprehensively test Vigoride in space, including its water-based propellant propulsion system.

Momentus' plans for additional launches of the Vigoride vehicle remain as stated in the Q1 earnings call on May 10, 2022, with agreements signed with SpaceX for launches on every upcoming Transporter mission through 2023.
