Boeing Starliner Faces Delays in Return Trip to Earth: An In-Depth Look
The Boeing Starliner, NASA’s newest crewed spacecraft, is experiencing delays in its return trip to Earth following a successful launch and docking at the International Space Station (ISS). The
United Launch Alliance Atlas V Rocket
from Cape Canaveral Air Force Station in Florida on May 19, 2019. After a near-perfect launch, the spacecraft successfully docked at the ISS on May 20. However, its journey back to Earth has hit some unexpected snags.
Misalignment with ISS Dock
The first issue arose during the spacecraft’s departure from the ISS. Due to a minor misalignment with the ISS, Boeing engineers had to manually override the Starliner’s autonomous landing system and abort the initial descent. Instead, the spacecraft remained at the ISS for an extended stay to allow engineers to work on a fix.
Parasitic Meteoroid Hit
A second challenge occurred when a tiny, parasitic meteoroid struck the Starliner’s heat shield during reentry. Although the impact did not cause any significant damage, it triggered an alarm in mission control, leading to a brief delay in the landing process.
Landing Site Selection
Additionally, Starliner’s landing site selection has caused a slight delay. Due to unfavorable weather conditions in the initial target area—White Sands Missile Range in New Mexico—the spacecraft was redirected towards the Atlantic Ocean for a splashdown landing. This change required additional preparations and coordination with recovery teams.
Impact on NASA’s Commercial Crew Program
These delays have slightly affected the overall timeline for NASA’s Commercial Crew Program. However, NASA and Boeing are working together to address these issues and ensure a successful return trip for the Starliner. This collaboration is crucial in advancing space travel and paving the way for crewed missions to the Moon, Mars, and beyond.
Stay tuned for updates on the Boeing Starliner’s return trip to Earth as we continue to monitor this exciting development in space exploration.
I. Introduction
The Boeing Starliner, a visionary spacecraft developed by Boeing as part of NASA’s Commercial Crew Program, is set to revolutionize the realm of space exploration. This cutting-edge vehicle, which operates under NASA’s contract that also includes SpaceX’s Crew Dragon, is designed with a dual capability: the transportation of both crew and cargo to Low Earth Orbit (LEO) and the ISS. The significance of this mission extends far beyond its commercial aspects, as it holds the potential to reduce dependency on Russia for crew transportation to the ISS and pave the way for future manned missions to the Moon and Mars.
Brief Overview of the Boeing Starliner Spacecraft
Initiated as a collaborative project between NASA and Boeing, the Boeing Starliner represents a monumental stride towards expanding the horizons of space travel. This reusable spacecraft, which employs commercial technologies to make space travel more cost-effective and accessible, is designed with a manned capsule atop an Atlas V rocket. The spacecraft’s innovative features include autonomous rendezvous and docking capabilities, enabling it to connect seamlessly with the ISS, and an integrated abort system for crew safety during launch.
Developed under NASA’s Commercial Crew Program
The Boeing Starliner is a product of NASA’s Commercial Crew Program, an initiative that aims to encourage private companies to develop and operate spacecraft capable of transporting crew to the ISS. By engaging commercial entities in this endeavor, NASA seeks to foster competition and innovation, leading to more efficient and cost-effective solutions for space travel.
Designed for Transportation to LEO and ISS
The Boeing Starliner’s versatile design allows it to transport both crew and cargo, making it a valuable asset for space exploration. Its capabilities extend to the transportation of up to seven passengers or approximately 18,000 pounds (8,200 kg) of cargo to LEO and the ISS.
Importance of the Starliner Mission in Space Exploration
The Boeing Starliner mission holds significant importance for space exploration, as it offers numerous benefits. Among these advantages is the potential to reduce dependency on Russia for crew transportation services to the ISS. With the Starliner’s successful completion of manned missions, NASA and its international partners can explore alternative options for crew transport, enhancing space exploration’s global reach and collaboration.
Moreover, the Boeing Starliner paves the way for future manned missions to destinations beyond LEO and the ISS. NASA’s plans for returning humans to the Moon through the Artemis program and eventual manned missions to Mars depend on advanced, reliable, and cost-effective spacecraft like the Boeing Starliner.
Background: Previous Starliner Mission (Crew-01) and Its Challenges
The Crew-01 mission of SpaceX’s Starliner spacecraft marked its first crewed flight to the International Space Station (ISS) on May 30, 2021, launching from Kennedy Space Center in Florida. With great anticipation, the spacecraft was expected to dock at the ISS on May 31, 2021. However, this mission encounters unexpected challenges that significantly influenced the course of the next flight.
Description of the Crew-01 mission
The Crew-01 mission was planned to carry NASA astronauts Michael Hopkins, Victor Glover, and Shannon Walker to the ISS, marking a significant milestone in commercial space travel. The spacecraft was expected to dock at the Harmony module of the ISS and deliver essential supplies and provisions for the crew.
Issues encountered during Crew-01 mission
Thruster malfunction: During the orbital insertion phase, one of Starliner’s thrusters malfunctioned, causing the spacecraft to miss its intended orbit and burn extra fuel. This malfunction required a manual re-entry procedure, which put the crew’s safety at risk.

Consequences of the challenges faced in Crew-01 mission
These challenges led to a delayed arrival at the ISS, preventing the crew from docking on May 31, 2021. The astronauts eventually arrived at the station on June 2, 2021, after a two-day journey. The mission’s unexpected complications required additional testing and modifications for Starliner before its next scheduled flight, Crew-02.
I Delays in Starliner’s Return Trip to Earth (Crew-02)
The scheduled launch date for the Starliner Crew-02 mission was initially set for August 3, 2021. However, several reasons for the delays emerged, primarily due to issues encountered during the Crew-01 mission. Among these issues were a thruster malfunction during orbit insertion and timing issues with the automated rendezvous and docking sequence.
To ensure the safety of future crews, NASA requested additional testing requirements. These included an inspection of the Starliner’s thermal protection system (TPS) and assessments on the propulsion and avionics systems. The thoroughness of these tests led to a significant
impact on Starliner’s schedule
and future missions.
The revised launch date for the Starliner Crew-02 mission is currently estimated to be
October 2021
. This delay could potentially cause delays in crew rotations for ongoing research projects at ISS, as well as
repercussions on the business model for private space companies
. The reliability and consistency of launch schedules are crucial factors in maintaining a steady workflow for research projects at the ISS, and any significant delays could disrupt the progress of these initiatives. Additionally, private space companies, such as SpaceX and Boeing, rely on a steady stream of business to remain profitable and competitive in the industry. Delays can lead to increased costs and decreased efficiency, potentially making it more difficult for these companies to deliver on their promises to customers and stakeholders.
Conclusion
