Overview of the data behind this chart

AI Insight

Valeri Polyakov's 437-day mission has stood as the record since 1995 - he volunteered for it specifically to prove humans could endure a journey to Mars, and no space agency has attempted anything longer since. The clustering just below him is telling: Oleg Kononenko and Nikolai Chub's 374 days and Frank Rubio's 371 days all happened in 2023-2024, yet none surpassed a mission flown on the aging Mir station using 1990s medicine. Rubio's American record was partly accidental - his six-month mission doubled when his return capsule was damaged by debris. With a one-way trip to Mars requiring roughly 200-250 days, every entry on this list already exceeds it, but a full round trip with surface time would demand far more than even Polyakov endured.
