The slowest rocket is generally considered to be the "Viking 1," which was launched in 1975 for a mission to Mars. It achieved a maximum speed of about 11,000 kilometers per hour (6,835 miles per hour) relative to Earth, which is relatively slow compared to modern rockets. Its slow speed was primarily due to the limitations of technology at that time and the mission's focus on a carefully planned trajectory to ensure a successful arrival at Mars.
