Has Anyone Been To Mars?
QUICK ANSWER
No humans have been to Mars. Many spacecraft have, including landers and rovers from the United States, Soviet Union, Europe, China, and the UAE. NASA's Curiosity (landed 2012) and Perseverance (landed 2021) rovers are still actively exploring the planet's surface today.
No human has set foot on Mars, and probably won't for at least another decade. But Mars has hosted more robotic visitors than any other body in the solar system besides our Moon. The history of Mars exploration is the history of increasingly capable robots doing what humans aren't ready to do yet.
What spacecraft have visited Mars?
Dozens. According to NASA, the first successful Mars flyby was Mariner 4 in 1965. The first successful landings were Viking 1 and 2 in 1976. The Sojourner rover (1997) was the first rover on Mars, followed by Spirit and Opportunity (2004), Curiosity (2012), and Perseverance (2021). NASA's InSight lander operated from 2018 to 2022. China's Zhurong rover landed in 2021. Multiple orbiters from various countries continue mapping and studying Mars from above.
What are the rovers doing now?
Exploring. NASA's Curiosity rover, in its 14th year on Mars, is still climbing through Gale Crater and studying ancient rock formations on Mount Sharp. NASA's Perseverance rover, in Jezero Crater, has been collecting rock samples and searching for signs of ancient microbial life. In 2024, Perseverance discovered a rock nicknamed Cheyava Falls with patterns that on Earth would be associated with microbial activity, though the finding is still being studied. Both rovers continue to send back panoramas, scientific data, and discoveries on a regular basis.
What happened to the Ingenuity helicopter?
Ingenuity, the small helicopter that traveled to Mars with Perseverance, made history as the first powered, controlled flight on another planet in April 2021. It was designed to make just 5 flights but ended up making 72 flights over nearly 3 years, far exceeding expectations. Ingenuity's mission ended in January 2024 when it sustained damage to a rotor blade during a landing. Despite the early end, Ingenuity proved that powered flight is possible in Mars's thin atmosphere.
When will humans actually go to Mars?
Not soon. NASA's Artemis program is focused on returning humans to the Moon as a stepping stone toward Mars, with crewed Moon missions in the late 2020s. SpaceX, which has talked about Mars colonization for years, announced delays in early 2026 to focus on lunar missions first. The technical challenges (radiation protection, long-duration life support, return propulsion, healthcare in microgravity) are still being worked out. Most realistic timelines put the first humans on Mars in the 2030s or 2040s, though no mission is currently scheduled.
No human has visited Mars yet, but the planet has been thoroughly explored by robots from multiple countries over the past 60 years. Curiosity and Perseverance continue their work, sending back data and samples that may eventually help future human missions plan their approach. Mars is well-known territory by robotic standards; the human visit is still ahead.
