Boeing's Starliner Successfully Launches with NASA Astronauts After Delays

Boeing's Starliner spacecraft, carrying NASA astronauts Butch Wilmore and Sunita Williams, has successfully launched on a United Launch Alliance's Atlas V rocket following a series of delays. The mission, initially scheduled for a month earlier, encountered multiple setbacks, including a valve issue in the rocket's upper stage and a helium leak in the Starliner's service module. However, the spacecraft lifted off at 10:52 am ET after ULA resolved a last-minute problem with ground-side topping valves. The astronauts are poised to spend eight days at the International Space Station, conducting tests to evaluate the Starliner's readiness for regular crewed missions. If successful, this mission will pave the way for the final certification of Starliner for future trips to the ISS.

Key Takeaways

  • Boeing's Starliner has successfully launched with NASA astronauts on board after multiple delays.
  • Launch issues included valve problems and a helium leak, which were resolved before liftoff.
  • Starliner transported 760 pounds of cargo, including 300 pounds of crew supplies to the ISS.
  • Astronauts will spend eight days on the ISS testing Starliner's readiness for regular missions.
  • Successful mission completion will lead to final certification for crewed space station rotations.


The successful launch of Boeing's Starliner, despite earlier technical issues, underscores the resilience of aerospace engineering. Resolving valve and helium leak problems before liftoff highlights the critical role of thorough pre-launch checks. Immediate benefits include enhanced operational capabilities for NASA and increased confidence in Boeing's spacecraft reliability. In the long term, a successful mission could lead to Starliner's certification, enabling regular crew rotations to the ISS and potentially bolstering Boeing's position in the space industry. This could also have an impact on the broader commercial space sector, setting a benchmark for safety and efficiency in space travel.

Did You Know?

  • Boeing's Starliner: The CST-100 Starliner, developed by Boeing as part of NASA's Commercial Crew Program, is designed to transport crew to the International Space Station (ISS) and other low Earth orbit destinations. It features a reusable capsule for up to seven passengers or a mix of crew and cargo and can stay in orbit for up to seven months before returning to Earth.
  • United Launch Alliance's Atlas V rocket: The Atlas V, produced by the United Launch Alliance (ULA), a joint venture between Lockheed Martin and Boeing, is known for its reliability and versatility in launching satellites and spacecraft. It comes in several configurations, determined by the number of solid rocket boosters and the type of payload fairing used.
  • Valve issue in the rocket's upper stage: The upper stage of a rocket is responsible for placing the payload into its final orbit. A valve issue in this stage can disrupt the flow of propellants, potentially causing a mission failure. Resolving a valve issue involves ensuring that the valves controlling the flow of fuel and oxidizer are functioning correctly, which is critical for the precise control of the rocket's thrust and trajectory.
