Mission schedule changes

23 recorded changes to planned mission dates across 14 mission records. 22 compare the same milestone before and after; 1 names no clear milestone, and is marked. The records describe 18 of the 23 as slips. Each links to the source on the mission's page.

Each recorded value is labelled with its milestone: launch, arrival, landing, delivery or readiness. Labels were checked against the sources on 28 October 2026, and two rechecked on 29 October: where a source dates a different milestone from the stored wording, the source's milestone is used; otherwise a value that names none takes its field's milestone, usually the launch. Dates for different milestones are not compared, because they cannot show how far a plan moved. Only changes recorded in a mission's history are listed. The earliest plan shown is the earliest one recorded here, which may not be the first plan ever announced. Dates keep the precision the source gave; a year-only change date is not more exact than that. A slip is not a result, and a plan is not a launch. Schedule announcements also appear on the timeline and upcoming pages.

How the planned dates changed

7 charts

Across: when the change was recorded. Up: the date then planned. The coloured band is the newest plan, a dashed edge means the plan began earlier than shown, and an arrow on top means no earlier than. × marks a recorded stop or a change to no stated date; nothing is drawn after it until the next recorded change. A band can be wider than the words it stands for; the table below gives them exactly. Only missions with at least two recorded changes that can be drawn appear here.
