Virgin Galactic self-reported an incident to the US Federal Aviation Administration (FAA) involving a detached alignment pin from its suborbital spaceplane’s attachment system.
This pin is critical for ensuring the correct alignment of the spaceplane, named Unity, to its mothership, VMS Eve, during ground preparations. Virgin Galactic emphasized the importance of this component for the safety and reliability of their operations.
The Role of the Alignment Pin
The alignment pin’s purpose extends beyond ground operations. During flight, it facilitates the transfer of load from Unity to the shear pin fitting assembly and into the mothership’s pylon and center wing.
Despite its detachment after Unity was released, Virgin Galactic assured that the pins “do not support the spaceship’s weight, nor do they have an active function once the spaceship is released.”
Assurance from Virgin Galactic
Following the incident, Virgin Galactic stated, “At no time did the detached alignment pin pose a safety impact to the vehicles or the crew on board.”
This incident occurred despite the recent success of Galactic 06, a mission that demonstrated the capabilities of their suborbital spaceflight system by carrying a crew of six more than 55 miles above Earth.
Impact on Future Flights
Virgin Galactic has plans for the next flight of Unity in the second quarter of 2024, The Register reports.
However, the company has cautioned that these plans are subject to review based on the outcome of the investigation into the detached pin incident. This event has prompted a thorough examination of their flight safety procedures and mechanisms.
Workforce and Operational Changes
SpaceNews reveals that in November 2023, Virgin Galactic’s CEO, Michael Colglazier, announced a significant operational pivot. The company will pause flights from mid-2024 to concentrate on developing the next generation of spaceplanes, the Delta class.
Additionally, approximately 18 percent of Virgin Galactic’s workforce will be let go as part of this strategic reorientation.
Safety and Maintenance Priorities
Virgin Galactic emphasized that the detached alignment pin did not compromise safety. This reassurance comes as VMS Eve had recently completed a comprehensive maintenance period, marking a transition to commercial operations, The Register notes.
The incident raises questions about the durability and reliability of the spacecraft components, even if they do not directly impact flight safety.
FAA Involvement in the Investigation
The FAA has acknowledged the incident, stating, “A mishap occurred during the Virgin Galactic Galactic 06 commercial human spaceflight mission… The mishap involved an issue with an alignment pin.”
The FAA’s oversight ensures that Virgin Galactic adheres to its FAA-approved mishap investigation plan and other regulatory requirements.
Virgin Galactic’s Discovery Process
The Register reports that Virgin Galactic discovered the missing pin through their camera system during routine post-flight reviews.
This proactive approach to safety and maintenance highlights the company’s commitment to adhering to the highest standards of spaceflight safety and operational integrity.
Clarification on the Delta Vehicles
Addressing potential concerns, Virgin Galactic clarified that the detached pin is a component of the mothership – VMS Eve, not the SpaceShipTwo spacecraft.
This distinction is crucial for understanding the specific functions and responsibilities of the different components of Virgin Galactic’s spaceflight system.
Reaffirming the Mission’s Success
Virgin Galactic reiterated the success of the Galactic 06 mission, stating it was conducted in accordance with the company’s rigorous flight procedures and protocols.
The detached alignment pin did not impact the safety of the crew or the success of the mission, underscoring the resilience of their safety measures.
Public Announcement and Market Reaction
Virgin Galactic made the incident public five days after notifying the FAA. This transparency did not negatively impact the company’s share price, which saw a slight increase in afterhours trading, SpaceNews reveals.
Virgin Galactic’s open communication about the incident demonstrates their commitment to transparency and safety.
Looking Forward to Galactic 07
Virgin Galactic is preparing for Galactic 07, the next mission, which will include a researcher and private astronauts, according to SpaceNews.
This upcoming flight, planned for the second quarter, represents an important step in Virgin Galactic’s mission schedule before the planned pause in flights to focus on the development of the Delta class spaceplanes.
