NASA Mulls Sending Cargo-Only Mission on Boeing's Starliner Test Flight

NASA is exploring the option of launching the upcoming Boeing CST-100 Starliner test flight without astronauts onboard, focusing solely on transporting cargo. This consideration arises as part of ongoing efforts to resolve technical issues within the spacecraft. Scheduled possibly for next year, this mission represents a significant milestone in Boeing and NASA’s pursuit of establishing reliable crewed flights aboard the Starliner. Citing SpaceNews, plans are under review to determine whether an uncrewed flight dedicated to cargo should proceed, especially following adjustments to the spacecraft’s electronic housing known as “doghouses.”

Addressing Starliner’s Safety and Performance Challenges

Designed to ferry astronauts to the International Space Station (ISS) via NASA’s Commercial Crew Program, Boeing’s CST-100 Starliner has faced development hurdles, including a major software error during the 2019 Orbital Flight Test-1, which prevented it from reaching the ISS. Since then, Boeing has been refining the systems to enhance safety and dependability for forthcoming astronaut missions.

At present, NASA is contemplating an uncrewed cargo-focused mission as a lower-risk means of validating modifications—particularly those made to the "doghouses." This strategy would allow firsthand evaluation of the updated systems in flight before committing to crewed launches. According to agency discussions, this approach could serve as a crucial step in confirming the spacecraft's readiness.

Benefits of Conducting Cargo-Only Missions First

Launching cargo-only flights ahead of crewed missions is a well-established method within space exploration. SpaceX followed this path using its Cargo Dragon deployments prior to initiating human spaceflights with Crew Dragon, providing critical operational data to support crew safety and mission success.

Boeing is considering a similar trajectory for Starliner, acknowledging the multiple benefits of a cargo-first flight approach. Such a mission would support thorough testing of spacecraft functionality and system reliability while reducing risk to astronauts. Verifying recent system upgrades during a cargo mission would enable effective troubleshooting before future crewed endeavors.

Outlook on Starliner’s Upcoming Crewed Missions

Although the next test flight of Starliner might exclude a crew, NASA is hopeful for the spacecraft’s role in transporting astronauts. Officials indicate work is progressing toward a launch as early as next year. The success of these flights is vital to NASA's collaboration with Boeing, ensuring the agency has dependable crew transport capabilities to the ISS.

Regardless of the precise timeline for manned flights, the anticipated cargo mission is expected to yield important insights. It will offer Boeing and NASA a valuable opportunity to detect and rectify any outstanding issues, thereby bolstering confidence ahead of crewed missions.
