Orbcomm prototype deorbits, falls to Earth

After an anomaly during the October 7 launch where one of the engines of the SpaceX Falco 9 failed to work, Orbcomm’s prototype satellite, the OG2, has been declared a total loss. The announcement came after the spacecraft failed to reach its designated International Space Station (ISS) safety gate for the second burn. As a result the OG2 found itself in a lower orbit. 

Orbcomm engineers studied plans to use the satellite’s propulsion mechanism to push the vessel into its intended orbit. However, the plans for a second burn was scrapped due to safety reasons. Many attribute the failure to the satellite being relegated to a secondary payload. Had it been the primary payload on the Space X mission, it would have reached its desired orbit. 

Orbcomm officials explained that despite the loss of the OG2, the vessel’s critical systems were tested and worked perfectly as it was designed. The telemetry and command capability of the satellite was also established, and various communications payloads of the OG2 were verified by engineers to have worked. 

Despite the setback, the company will still work with SpaceX for future launches of its second-generation satellites. Orbcomm remains confident in the American space transport company.
