What was the first American spacecraft to land on the planet Mars?




Viking 1

There have been many failed – and several successful – almost 500-million-mile trips to Mars by spacecrafts launched from all over the globe.




Cheers erupted from the U.S. on July 20, 1976, as Viking 1 became the first American spacecraft to land on Mars’ surface. The planned landing date was July 4, but it was pushed back due to safety concerns. For six years, Viking 1 remained on the planet, sending images and data back to Earth. Source: Space.com
