Momentus First Demonstration Mission Update #3

About this update from Momentus Inc.

[{"type":"text","content":" SAN JOSE, Calif.--(BUSINESS WIRE)--\nMomentus Inc. (NASDAQ: MNTS) (\"Momentus\" or the \"Company\"), a U.S. commercial space company that plans to offer transportation and other in-space infrastructure services, today provided its third Mission Update since the launch of its Vigoride-3 spacecraft on May 25.\n\nAs we previously stated in earlier updates on the inaugural flight of the Vigoride orbital transfer vehicle, the spacecraft experienced anomalies after its launch on May 25. Since that time, we have continued work to address the anomalies and identify root causes. Of note, the deployable solar arrays that are produced by a third party and are folded and stowed during launch did not operate as intended once in orbit. This resulted in power and communications issues with the vehicle, even though the body mounted solar panels did operate as intended. We have been working closely with the third-party producer of the solar arrays, and in collaboration with that company have identified what we believe is the root cause of the arrays not operating as intended. We also believe we have identified the likely root cause of the other anomalies, although further analysis continues.\n\nAfter initially experiencing these anomalies, we were able to deploy two customer satellites from Vigoride on May 28. Since that time, we have continued efforts to deploy other customer satellites, but have not confirmed any subsequent deployments. While we previously established two-way communications with the Vigoride vehicle, we have not been able to continue such two-way communication, which we believe is due to the low power situation on the vehicle due to the deployable solar arrays not operating as intended.\n\nIn an earlier update on May 27, we indicated that we were using an unplanned frequency as we worked through the anomalies and were applying for a Special Temporary Authority (STA) from the FCC to address that situation. On June 9, we received approval of a 30-day STA from the FCC as requested.\n\nWe are continuing efforts to address the anomalies, but our level of confidence that we will be able to deploy additional customer satellites from Vigoride and perform some planned operations of the vehicle on this test and demonstration mission has substantially declined.\n\nOn a second port on the launch vehicle on May 25, we also used third part...
