  "account": "On September 4, 1962, NASA's Mariner 2 spacecraft carried out the first-ever rocket maneuver in deep space, making a mid-course correction en route to Venus. The spacecraft had launched just eight days earlier and required the maneuver to ensure its trajectory would lead it to Venus. The Atlas-Agena rocket that launched Mariner 2 did not have the necessary precision to achieve the correct trajectory in a single maneuver. Approximately 1.5 million miles (2.4 million kilometers) from Earth, the spacecraft fired its engines to steer itself in the right direction. This five-commanded maneuver, implemented by mission control, involved rolling, pitching, turning, and burning the rocket motor. One hundred days later, Mariner 2 successfully flew by Venus and became the first spacecraft to accomplish a successful flyby of another planet. While mid-course corrections in deep space are now commonplace, they were far from routine in 1962 when reaching another planet with a probe was still a distant dream.",
