Former Astronaut Explains the Reasons Behind the 24-hour Wait before Starliner’s Next Launch
Former NASA astronaut Robert Behnken, who flew on SpaceX’s Demo-2 mission last May, recently shared insights into the reasons behind the 24-hour wait before Boeing’s Starliner spacecraft is set to fly again. The delay comes after a “timeline error” that occurred during the Starliner’s initial flight test in December 2019, which resulted in the capsule orbiting Earth instead of docking with the International Space Station (ISS).
Understanding the Consequences of the Timeline Error
Boeing’s Starliner experienced a few anomalies during its unmanned test flight. The most significant issue was a “computer-generated error,” which caused the spacecraft to believe it had already performed an orbital insertion maneuver. This error led Starliner to prematurely separate from the Atlas V rocket and start its de-orbit procedure, which ultimately resulted in an unplanned re-entry into Earth’s atmosphere. Although the spacecraft splashed down safely in the Atlantic Ocean, it missed its target by over 40 miles, requiring a costly recovery operation.
Assessing the Impact on Starliner’s Next Launch
The 24-hour delay before Starliner’s next launch is not solely due to the initial error. Boeing must conduct a thorough investigation and make any necessary corrections to ensure the spacecraft’s safety and success. The company is performing an extensive review of their software, testing procedures, and training programs to prevent similar errors in future missions.
Boeing’s Commitment to Safety
Behnken, who flew on SpaceX’s Dragon spacecraft for NASA’s Commercial Crew Program, expressed his support for Boeing during this time. He emphasized the importance of rigorous testing and adherence to safety protocols in the space industry.
Quote from Robert Behnken
“Everyone’s goal is to make sure we fly safely and effectively. [Boeing] will do everything they can to ensure that the spacecraft is ready for launch,” Behnken said during an interview with CBS News. “They are taking their time, and I think that’s the right approach.”
Impact on Commercial Crew Program
The setback for Starliner affects NASA’s Commercial Crew Program, which aims to have at least two independently operated human-rated spacecraft capable of transporting crews and cargo to the ISS. SpaceX’s Dragon has already carried astronauts to the ISS, but Boeing’s Starliner has yet to do so.
Conclusion
Boeing’s 24-hour delay before Starliner’s next launch is a result of the initial timeline error and the thorough investigation that followed. The company is taking every precaution to ensure the safety and success of future missions. Boeing’s commitment to rigorous testing and adherence to safety protocols is essential in the advancement of commercial space travel.

I Reason 2:: Time Requirements for Prelaunch Activities
Description of the complex processes involved in preparing a spacecraft for launch
Preparing a spacecraft for launch is an intricate and time-consuming process. Fuelling, electrical tests, and software checks are just some of the complex processes that must be carried out meticulously before a spacecraft can be cleared for liftoff. Fuelling involves filling the rocket’s tanks with liquid oxygen and liquid hydrogen, which must be cooled to extremely low temperatures before use. This process can take several hours due to the time required for cooling and the need for precise measurements to ensure safe loading levels.
Discussion on how these processes contribute to the launch timeline
The time required for prelaunch activities can significantly impact a mission’s launch schedule. For instance, delays in software checks, which verify that all onboard systems are functioning correctly, can cause major disruptions. Similarly, electrical tests must be completed to ensure the spacecraft’s power systems are operational. These tests often require extensive coordination with ground control teams and, if applicable, the International Space Station (ISS) crew to ensure a seamless handover.
Comparison of prelaunch activities between SpaceX and Boeing, emphasizing the importance of consistency and efficiency
Both SpaceX and Boeing undergo extensive prelaunch preparations. However, their approaches differ in terms of consistency and efficiency. SpaceX’s reusable Falcon 9 rockets and Dragon spacecraft streamline the prelaunch process by reducing the need for extensive refurbishment between launches. This approach has led to a significant decrease in time spent on prelaunch activities and an increase in launch frequency.
On the other hand, Boeing’s Starliner spacecraft follows a more traditional approach, requiring extensive refurbishment between missions. This adds to the overall time required for prelaunch activities and increases the risk of delays due to unforeseen issues during refurbishment. However, it is important to note that consistency and efficiency are key to minimizing these risks and ensuring successful launches for both companies.
