What crimes or conduct by a former astronaut and Navy officer could trigger military jurisdiction today?
Executive summary
A former astronaut who is also a former Navy officer can be subject to military-related jurisdiction today under several narrow authorities: the Military Extraterritorial Jurisdiction Act (MEJA) for felonies committed abroad while “employed by or accompanying” the U.S. armed forces, and various federal or military mechanisms when conduct occurs on U.S. military property or implicates national security or war‑time statutes (examples and procedures in the Justice Manual and Federal Register guidance) [1] [2]. Sources do not provide a single checklist specific to “former astronauts,” but explain the legal pathways and jurisdictional triggers that could apply to former service members or civilians in similar positions [1] [2].
1. How military jurisdiction normally reaches former service members — the statutory gateways
Congress and the executive branch have carved specific statutory routes by which non‑active personnel can fall under military or related federal jurisdiction: MEJA extends federal criminal jurisdiction to former members of the Armed Forces for specified felonies committed outside the United States while associated with the forces, and other statutes and memoranda (including DoJ–DoD MOU language summarized in the Justice Manual) treat certain offenses tied to military activities as if they occurred on a military installation for jurisdictional purposes [1] [2].
2. Location matters: on base, off base, and overseas distinctions
Where the conduct occurred is decisive. Crimes committed on an installation with exclusive federal jurisdiction may be handled by federal authorities or military investigative arms; similarly, the Department of Justice/DoD memorandum says crimes tied to scheduled military activities outside an installation (e.g., organized maneuvers) can be treated as if on base for jurisdictional purposes [3] [2]. Conversely, civilians and former service members who commit crimes abroad may fall under MEJA or under host‑nation jurisdiction depending on status and agreements [1] [4].
3. Types of conduct most likely to trigger military-related jurisdiction
Sources highlight categories that commonly produce military or federal jurisdictional claims: serious violent crimes, weapons violations, drug trafficking on federal property, and offenses implicating military discipline or operations — and crimes tied to scheduled military activities are treated specially under the DoJ–DoD guidance [5] [2]. Academic and practical summaries also list espionage, illegal disclosure of classified information, fraud, and other offenses that intersect military interests, though the precise reach depends on statutory language and whether the act affects military order [6] [2].
4. Extraterritorial reach: MEJA and its limits
MEJA (codified in title 18, chapter 212) is the principal mechanism for prosecuting certain felonies by civilians and former military personnel overseas when they were employed by or accompanying the U.S. forces; it fills gaps where neither host nation nor U.S. state law applies [1]. But MEJA covers felonies punishable by more than one year and has procedural and scope limits; sources note gaps historically left many civilians abroad without U.S. jurisdiction absent bilateral arrangements [1] [4].
5. Overlap and concurrent jurisdiction: who decides — military, federal, or state?
Jurisdictional outcomes often depend on concurrence, requests, and agreements: the Justice Manual describes coordination between DoJ and DoD and states that DoD will notify DoJ in many cases and that DoJ investigative agencies may assume jurisdiction with appropriate concurrence [2]. On U.S. soil, exclusive federal jurisdiction over military reservations means the federal government often leads; off base, states sometimes retain prosecutorial authority unless the military requests and obtains jurisdiction [3] [7].
6. Practical examples and gaps in the record about “former astronauts” specifically
Available sources do not discuss former astronauts by name or set out astronaut‑specific rules; instead they explain rules applicable to former service members, civilians accompanying forces, and conduct on or tied to military operations [1] [2]. That means application to any former astronaut would turn on their civilian/employment status at the time of alleged misconduct, location of the act, and whether the conduct touched military operations or national security [1] [2].
7. Competing perspectives and legal friction points to watch
Legal commentary and government guidance reflect tradeoffs: national security and discipline push for broad jurisdictional tools (DoD/DoJ MOU), while civil‑liberties and sovereignty concerns constrain military courts and extraterritorial reach (historical GAO and academic critiques note jurisdictional gaps and the need for legislative fixes) [2] [4] [8]. International and host‑nation arrangements (SOFAs, Status of Forces agreements) create additional variability in outcomes [4] [9].
Limitations: reporting and materials provided do not enumerate every statute or case law example; they summarize major mechanisms (MEJA, DoJ–DoD MOU, federal jurisdiction on installations) and describe categories of crimes more likely to trigger military or federal jurisdiction rather than providing an exhaustive list tailored to “former astronauts” [1] [2].
