Boeing's Starliner Spacecraft Docks at ISS Despite Propulsion System Leaks and Thruster Failure

In a significant development for the space industry, Boeing's CST-100 Starliner spacecraft successfully docked at the International Space Station (ISS) on June 13, 2024. The docking marked a crucial achievement for NASA and Boeing as it paved the way for potential private astronaut missions in the future. However, this milestone came after Starliner encountered several challenges during its journey to the ISS.

Before launch, engineers identified four helium leaks in Starliner's propulsion system. One of these leaks was previously known before launch, while the other three were discovered during the spacecraft's time in orbit. NASA and Boeing worked together to assess the impact of these leaks on the remainder of the mission.

Additionally, one reaction control system (RCS) thruster failed during Starliner's flight to the ISS. Engineers are currently studying a RCS thruster that shut down during the spacecraft's journey and an RCS oxidizer isolation valve in Starliner's service module that is not properly closed. These issues may affect undocking and deorbit maneuvers.

Despite these challenges, NASA astronauts Butch Wilmore and Suni Williams safely entered the ISS on June 13. The mission was initially scheduled to last for a week but has been extended due to the need for ISS astronauts to prepare for a spacewalk and Starliner teams to continue their assessments.

Boeing plans to redesign valves on Starliner's propulsion system following the identification of a flaw in 2022. NASA is providing $5.5 million for potentially redesigning Starliner's batteries as well.

The successful docking of Boeing's CST-100 Starliner spacecraft marks an important step forward for the company and the space industry as a whole, but there are still many hurdles to overcome before routine missions can become a reality.

Confidence

90%

Doubts
  • The article mentions that one RCS thruster failed during flight, but it does not specify which one. Are all RCS thrusters affected?
  • The article states that NASA is providing $5.5 million for potentially redesigning Starliner's batteries, but it does not provide a source for this information.

    • Fifth leak was considerably smaller than others at 1.7 psi per minute
    • Engineers are studying one RCS thruster that shut down during flight, an RCS oxidizer isolation valve not properly closed
  • Accuracy
    • Five helium leaks have been detected in Boeing's CST-100 Starliner spacecraft.
    • One leak was detected during launch, four after docking with ISS.
    • Starliner has enough helium for 70 hours of flight operations, only seven hours needed for return to Earth.

Starliner flight is one big step for Boeing's space capsule, but many hurdles remain

KSL News Thursday, 13 June 2024 02:03
  • Unique Points
    • Boeing's Starliner spacecraft delivered two astronauts to the International Space Station on Thursday, marking a safety demonstration for NASA and potential private astronaut missions.
    • Boeing plans to redesign valves on Starliner’s propulsion system after identifying a flaw in 2022 and is receiving $5.5 million from NASA for potentially redesigning Starliner’s batteries.
  • Accuracy
    • The number of helium leaks detected in the article is inconsistent. The article states four helium leaks after docking with ISS while other articles state five.
    • The size and significance of the fifth helium leak is not consistent between articles. Some state it was considerably smaller than others while others do not mention its size.
  • Deception (30%)
    The article contains selective reporting as it only reports on the problems encountered by Boeing's Starliner spacecraft during its journey to the International Space Station and does not mention any successes or positive aspects of the mission. It also uses editorializing language such as 'nagging concern' and 'distant prospect' to manipulate emotions and create a negative perception of Boeing.
    • The helium leaks and propulsion failures, while no danger to astronauts, NASA officials said, are a nagging concern.
    • It’s not yet clear to NASA officials if the issues that occurred during Starliner’s first crewed mission would warrant redesigns.
    • But before Boeing can chip away at SpaceX’s grip on government and private orbital human spaceflight, its Starliner has several more test objectives to reach.
  • Fallacies (75%)
    The article does not contain any formal fallacies. However, it does present some informal fallacies and a dichotomous depiction. The author presents Boeing's Starliner spacecraft as having achieved a significant milestone with the delivery of two astronauts to the International Space Station, but also highlights several problems encountered during the journey and more hurdles that lie ahead. This creates a dichotomous depiction, presenting Starliner's success and failures side by side without acknowledging that these are both part of a complex process. Additionally, the author quotes Patricia Sanders as saying 'If they can’t successfully transport human beings to space, and safely return them, then they haven’t proven what they need to do to conduct any missions.' This is an appeal to authority. The article also mentions Boeing's Starliner development challenges costing the company roughly $1.5 billion, which could be seen as an inflammatory rhetoric by implying that these costs are a result of Boeing's inefficiencies or mistakes. Overall, while there are no blatant fallacies, the article does present some informal fallacies and a dichotomous depiction.
    • The CST-100 Starliner capsule’s first crewed docking with two astronauts to the International Space Station on Thursday marked a long-sought safety demonstration for two audiences: NASA, which wants a second U.S. spacecraft for rides to orbit, and the nascent market for private astronaut missions that is currently dominated by Elon Musk's SpaceX and its Crew Dragon capsule.
  • Bias (95%)
    The article does not demonstrate any clear bias towards a specific political, religious, ideological or monetary position. However, the author does use language that depicts Boeing's Starliner spacecraft as having encountered 'problems' and 'hurdles' during its journey to the International Space Station. While this language is neutral in itself, it could be perceived as implying that there are issues with the Starliner that need to be addressed before it can compete with SpaceX's Crew Dragon capsule. However, this interpretation is not definitively stated in the article and could be a reasonable assessment of the situation given the information provided.
    • But problems encountered along its journey in space and more hurdles that lie ahead make the aerospace giant's goal toward routine missions a distant prospect.
      • It's not yet clear to NASA officials if the issues that occurred during Starliner’s first crewed mission would warrant redesigns.
