The independent team NASA and Boeing, which was formed to investigate Starliner’s failed flight to the ISS, has completed its investigation. And based on NASA’s announcement, they have to make a fairly long list of changes before the spacecraft can launch astronauts into space. The joint review team ended its investigation with 80 recommendations to NASA and Boeing. The most notable suggestion was to run end-to-end tests using the maximum amount of flight hardware before each flight.
One of the main reasons why the Starliner̵
7;s first flight failed was because Boeing divided its tests into small parts instead of doing a longer one that simulated the whole process from takeoff to docking. As a result, the aerospace company did not find that the spacecraft’s on-board time was incorrectly calibrated by 11 hours, preventing the Starliner engines from firing and being sent into orbit. In addition, Boeing has not tested the Starliner software with the service module. The company used an emulator that was faulty and did not discover a critical software bug that could have resulted in “vehicle loss”.
