Starliner: What Caused the Propulsion Problems During Orbital Flight Test-2?

A Deep Dive into the Root Causes of the Starliner's Propulsion Issues

Experts Attribute the Problems to a Combination of Factors

After months of meticulous investigation, engineers have finally unveiled the potential causes behind the propulsion problems experienced by Boeing's Starliner spacecraft during its Orbital Flight Test-2 (OFT-2) mission to the International Space Station (ISS).

Contributing Factors to the Propulsion Issue

• Software Error: A software error in the Starliner's propulsion system caused the spacecraft to fire its engines incorrectly, resulting in insufficient thrust to reach the ISS.
• Fuel System Leakage: A fuel line leak occurred during the spacecraft's ascent, causing a loss of propellant and affecting the propulsion system's performance.
• Sensor Failure: A sensor responsible for detecting the spacecraft's orientation malfunctioned, leading to incorrect data being sent to the propulsion system, which further contributed to the propulsion issues.

Consequences of the Propulsion Problems

The propulsion problems had several significant consequences for the OFT-2 mission:

• Unsuccessful Docking: The spacecraft was unable to dock with the ISS due to insufficient propulsion.
• Extended Stay in Orbit: Astronauts Butch Wilmore and Suni Williams had to remain in orbit for an additional six weeks, as the Starliner was not capable of returning to Earth immediately.
• Additional Costs: The extended stay and additional resources required for the mission resulted in increased costs for Boeing.

Steps Taken to Address the Issues

Boeing and NASA have taken several steps to address the propulsion problems and prevent similar issues in the future:

• Software Updates: The software responsible for the propulsion system has been updated to prevent similar errors from occurring.
• Fuel Line Redesign: The fuel line has been redesigned to minimize the risk of leakage.
• Additional Sensor Redundancy: Redundant sensors have been added to ensure accurate data is always available to the propulsion system.

Moving Forward with Future Missions

With the propulsion issues addressed, Boeing and NASA are working towards future Starliner missions. The spacecraft is expected to play a crucial role in the agency's plans for human space exploration.
