Longest spaceflight by an American astronaut

September 1, 2024

With the two astronauts stuck on the ISS, how long was the longest spaceflight ever taken by an American astronaut? In days, was it … A.) 371, B.) 665, C.) 204 or D.) 225?

The answer: A.) 371. Astronaut Frank Rubio set NASA’s record for the single longest continuous spaceflight just last year. Luckily, he had the comforts of the ISS to keep him company.

If you guessed 665 days, you’re close — that’s the total time Peggy Whitson spent in space over her career, making her the NASA astronaut with the most cumulative days in space.
