This question resolves YES to every above-listed Justice who resigns, dies, or for any other reason officially ceases to be a member of the Supreme Court of the United States before the end of 2024 (otherwise resolving NO on 1 Jan 2025; if no Justice ceases to be a member, then all options resolve NO).
There are nine Justices, two of whom are in their 70s (Thomas, Alito), and one of whom (Sotomayor) is the subject of debate over whether she should resign to guarantee a successor with similar views.
The Justices, in-order of time on the court, along with their ages (as of time of writing) and the party that appointed them:
Clarence Thomas (75, Republican)
John Roberts (69, Republican)
Samuel Alito (74, Republican)
Sonia Sotomayor (69, Democrat)
Elena Kagan (64, Democrat)
Neil Gorsuch (56, Republican)
Brett Kavanaugh (59, Republican)
Amy Coney Barrett (52, Republican)
Ketanji Brown Jackson (53, Democrat)
