Frequently Asked Questions
How many missions have been sent to Mars?▾
Over 50 missions have been sent to Mars since 1960, by the Soviet Union, NASA, ESA, ISRO, CNSA, UAE, and JAXA. Roughly half have failed due to the extreme difficulty of reaching and landing on Mars — earning it the nickname 'the Bermuda Triangle of space.'
Which country has the most successful Mars missions?▾
NASA (United States) leads with the most successful Mars missions, including 5 rovers (Sojourner, Spirit, Opportunity, Curiosity, Perseverance), multiple orbiters (MRO, MAVEN, Odyssey), and landers (Viking 1 & 2, Phoenix, InSight). China (CNSA) achieved a remarkable first with Tianwen-1, deploying an orbiter, lander, and rover on its first Mars attempt.
Is there a rover on Mars right now?▾
Yes, as of 2026 there are two active rovers on Mars: NASA's Curiosity (operating since 2012 in Gale Crater) and NASA's Perseverance (operating since 2021 in Jezero Crater). China's Zhurong rover entered hibernation in May 2022 and has not resumed contact.
When will humans go to Mars?▾
No confirmed date exists for a crewed Mars mission. SpaceX aims for the 2030s with Starship, though many experts consider this aspirational. NASA's current roadmap targets crewed Mars missions in the late 2030s to 2040s, building on Artemis lunar experience. China has announced plans for crewed Mars missions around 2033.
Will Mars samples be brought back to Earth?▾
NASA and ESA's Mars Sample Return mission aims to retrieve the 24+ sample tubes cached by Perseverance, but the program faces budget challenges and is being redesigned. China's Tianwen-3 is an independent Mars sample return mission planned for ~2028 that could return samples to Earth before the NASA/ESA effort.
What was the first successful Mars mission?▾
NASA's Mariner 4 performed the first successful Mars flyby on July 14–15, 1965, returning 22 close-up photos of Mars. The first successful Mars orbiter was Mariner 9 (1971), and the first successful lander was Viking 1 (1976).
Which Mars rover lasted the longest?▾
NASA's Opportunity rover holds the record at nearly 15 years of operation (2004–2018) and 45.16 km driven. Curiosity, still active since 2012, has surpassed 12 years of operation.
Has life been found on Mars?▾
No confirmed evidence of life has been found on Mars. However, Curiosity and Perseverance have detected organic molecules, Perseverance found evidence of ancient river deltas in Jezero Crater, and Mars Express detected a possible subsurface liquid water lake. Mars Sample Return would provide the best chance to determine if Mars ever harbored microbial life.
