Trump's advanced age of 79, the rigorous physical and medical requirements for astronaut training, and the absence of any announced plans from NASA, SpaceX, or his administration have solidified trader consensus at 98% against him undertaking spaceflight in 2026, where the U.S. threshold is 50 miles above sea level. As president, Secret Service protocols, national security constraints, and a demanding schedule further preclude participation in crewed missions like Artemis or private orbital/suborbital flights. Recent highlights include his April 29 White House meeting with the Artemis II lunar flyby crew, where he joked about his fitness but signaled no personal intent. Only an improbable late-year surprise announcement and expedited training could shift odds, amid NASA's focus on professional astronauts for 2028 moon goals.
