Descrição:

There was a lot of space exploration going on in the late 60s and early 70s due to the space race between the United States and the USSR. Not all of it was to Mars, but each country said they would land on Mars first, putting immense pressure on both sides to do the most at the quickest rate, hence the several Mars missions during the time.
