Discover the monumental first crewed flight of Boeing’s CST-100 Starliner, marking a significant milestone in space exploration and advancing NASA’s Commercial Crew Program.
On June 5, 2024, at 10:52 a.m. EDT, Boeing’s CST-100 Starliner successfully launched atop a United Launch Alliance Atlas V rocket from Cape Canaveral Space Force Station in Florida. This mission, known as the Crew Flight Test (CFT), marked a significant milestone in human spaceflight, showcasing the resilience and determination of NASA, Boeing, and their partners.
Mission Overview
The Starliner spacecraft successfully separated from the Centaur upper stage of the Atlas V rocket at approximately 12:06 p.m. EDT, completing its orbital insertion burn and a subsequent burn to circularize its orbit. This successful launch follows two previous attempts on May 6 and June 1, which were scrubbed due to technical issues. The mission is set to last over a week, carrying NASA astronauts Butch Wilmore and Sunita Williams to the International Space Station (ISS).
Launch Details
- Launch Time: June 5, 2024, at 10:52 a.m. EDT
- Launch Vehicle: United Launch Alliance Atlas V rocket
- Launch Site: Cape Canaveral Space Force Station, Florida
- Mission Duration: Over a week

Overcoming Challenges in the First Crewed Flight of Boeing’s CST-100 Starliner
The path to this historic launch was fraught with challenges. The first attempt on May 6 was halted due to an oxygen pressure relief valve issue on the Atlas V rocket’s upper stage. Subsequent investigations revealed a helium leak in the Starliner’s service module, causing further delays. The second attempt on June 1 was scrubbed when one of the three ground launch sequencer circuit boards failed to synchronize with the others. Despite these setbacks, the combined efforts of NASA, Boeing, and ULA teams ensured that the mission proceeded successfully.
Key Mission Phases
Launch Preparation and Countdown
The meticulous preparation for the launch involved resolving technical issues and ensuring all systems were functioning optimally. The 45th Weather Squadron provided a favorable weather forecast, with a 90 percent chance of suitable conditions for liftoff. The main concern was cumulus clouds and potential solar activity, which were monitored closely.
Orbital Insertion and Burns
Following a successful separation from the Centaur upper stage, the Starliner completed its orbital insertion burn 31 minutes into the flight. A subsequent burn at T+1 hour and 15 minutes circularized its orbit, setting the stage for docking with the ISS. These precise maneuvers are crucial for ensuring a safe and stable orbit, enabling the spacecraft to rendezvous with the space station.
Docking with the ISS
The Starliner is scheduled to dock with the ISS at approximately 12:15 p.m. EDT on June 6, 2024. This docking will be a critical phase of the mission, demonstrating the spacecraft’s ability to safely and effectively transport astronauts to and from the space station. The success of this phase will pave the way for future crewed missions.
Return and Landing
If all goes as planned, the Starliner and its crew will return to Earth on June 14, 2024, with a landing in White Sands, New Mexico. This return will mark the completion of a significant milestone in Boeing’s journey to provide reliable crew transportation services as part of NASA’s Commercial Crew Program.
The Future of Boeing’s Starliner
Certification and Full Crew Rotation Missions
Following the successful completion of the CFT mission, Boeing will collaborate with NASA to finalize the certification process for the Starliner spacecraft. This certification is essential for initiating full crew rotation missions, which could begin as early as the spring of 2025. These missions will play a crucial role in maintaining the continuous human presence on the ISS and advancing scientific research in space.
Commercial Crew Program
The success of the Starliner mission is a testament to the achievements of NASA’s Commercial Crew Program, which aims to foster collaboration with private companies to develop and operate crew transportation systems. Alongside SpaceX’s Crew Dragon, Boeing’s Starliner will enhance the United States’ capability to launch astronauts into space from American soil, reducing reliance on foreign spacecraft and bolstering the nation’s space exploration efforts.
The Significance of Sunita Williams’ Heritage in Space
Sunita Williams, an Indian American astronaut, has a rich history of integrating her cultural heritage into her space missions. On previous flights, Williams brought sacred texts like the Upanishads and the Bhagavad Gita, along with samosas and a statue of Ganesh, the Hindu deity. Her actions resonate deeply with the Indian diaspora and highlight the diverse backgrounds of astronauts representing NASA.
Cultural Symbols in Space
Williams’ inclusion of cultural items aboard her missions signifies more than personal comfort; it represents the confluence of different cultures and the human aspect of space exploration. These symbols provide not only a sense of home but also an inspiring narrative for millions around the world.
The first crewed flight of Boeing’s CST-100 Starliner represents a significant achievement in the realm of space exploration. Overcoming numerous challenges, this mission highlights the dedication and perseverance of the teams involved. As we look to the future, the successful completion of this mission sets the stage for further advancements in human spaceflight, heralding a new era of exploration and discovery.
