Starliner’s April 2021 Schedule
Starliner testing was a key step towards carrying astronauts to the International Space Station. In April 2021, reports pointed to a late-summer launch for Starliner’s second uncrewed demonstration. However, the proposed timing was a target rather than a completed mission.
Our original coverage highlighted Spaceflight Now’s April 2021 report. It described plans for an August or September launch from Cape Canaveral. Meanwhile, the earlier schedule had targeted 2 April.
Preparing Starliner for Launch
Preparations for the Boeing capsule test flight linked the schedule change to software testing delays. In addition, it discussed disruption from a February winter storm affecting Boeing’s Houston software laboratory. These preparations formed part of the work needed before the next demonstration.
The first orbital demonstration had fallen short of reaching the space station. Therefore, the second test offered another opportunity to assess the system before a flight with astronauts. The distinction matters: an uncrewed test checks capabilities without carrying a crew.
Boeing Capsule Test Flight: Later Launch Changes
The Starliner mission faced further changes later in the year. For example, NASA announced that teams would stand down from an August launch attempt while examining unexpected propulsion valve indications.
Read NASA’s August 2021 update for that later development. This shows why readers should treat the April schedule as a historical snapshot. In particular, a planned launch window does not guarantee that a spacecraft will fly within it.
