April 2020 - November 2021

The Boeing CST-100 Starliner is a reusable crew capsule designed to transport crews to the International Space Station (ISS) and other private space stations. Starliner can accommodate up to seven passengers or a mix of crew and cargo. The spacecraft can be reused up to ten times.

Starliner is slightly larger than the Apollo command module with a diameter of 15 feet. It is designed to be compatible with the Atlas V, Delta IV, Falcon 9, and Vulcan Centaur launch vehicles.

In 2010, Boeing was awarded $18 million by NASA for the preliminary development of Starliner. In the following years, NASA would continue to award Boeing with more money as it continued its Commercial Crew Program. As part of that program, Starliner embarked on its maiden voyage, Starliner Orbital Test Flight, an uncrewed flight to the ISS. Unfortunately, due to software glitches, Starliner had to return to Earth, never reaching the ISS. Boeing continues to develop the spacecraft for future crewed flights.

OFT-2 launch likely delayed to 2022, service module may be replaced, nobody is surprised

To put it bluntly, Boeing’s attempts at an Orbital Flight Test of their CST-100 Starliner capsule have been a complete wreck. The success of Starliner is imperative so NASA will have redundant systems for access to the ISS, but a delay to 2022 is unsurprising.

[Update: Delayed: Awaiting new date] Next Launch: Boeing Starliner to conduct its second orbital test flight

Update: A few hours before launch Boeing announced that the launch was postponed due to issues with “unexpected valve position indications” used in the propulsion system.


After the missed opportunity to dock with the International Space Station due to a timer issue on its first flight a second test flight was needed. Boeing will be performing their second orbital flight test for their Starliner crew capsule as soon as Friday to dock with the ISS. This will also serve as the final test before NASA puts crew onboard to determine if it’s ready.

Date: Tuesday, August 3rd at 1:20 p.m. EDT

Boeing pauses critical Starliner OFT-2 mission to ISS over propulsion system issue

After a year and a half of focusing on software issues, Boeing has paused its Starliner Orbital Flight Test 2 (OFT-2) mission to the International Space Station today. The launch was scheduled for this afternoon but scrubbed hours before liftoff due to a propulsion system issue with the spacecraft.

Boeing’s mission is to have its uncrewed Starliner spacecraft reach the International Space Station and return safely before it can be rated for human spaceflight. Boeing is one of two providers for NASA’s Commercial Crew Program (along with SpaceX) to transport astronauts to and from the space station.

[UPDATE: RL-10C engine use further delayed] ULA sends Boeing’s Crewed Flight Test booster to Florida ahead of the next uncrewed test

United Launch Alliance loaded an Atlas V Booster and Dual Engine Centaur onto their Rocketship boat over the weekend. Its destination? Florida. This isn’t just any ordinary Atlas V though, this will be the first one to carry crew to space. The Boeing Starliner Crewed Flight Test (CFT) is still expected NET late 2021. However, a second Orbital Flight Test is needed.
