Which year did the rovers land on mars?

Answer 1

A 1973 Russian mission, Mars 6, actually did land on the surface, but lost communication after just a few seconds. America's Viking 1 landed on Mars on July 20, 1976, exactly seven years after Neil Armstrong made his giant leap, and Viking 2 landed on the opposite side of the planet two months later. Both Viking spacecraft took thousands of images and measured atmospheric conditions. But perhaps most important, they collected soil samples with a scoop, put them through chemical analyses and sent the results back to Earth. The first mobile mission to Mars was the pyramid-shaped Pathfinder which made it to the surface in 1996— the first to do so since the Viking missions 20 years before — it set up a weather station and released its six-wheeled Sojourner rover to explore. Scheduled to last just 30 days, both the lander and Sojourner sent images and data back for almost three months before contact was lost. Mars Exploration Rovers, Spirit and Opportunity landed on Mars. Like the 1996 Pathfinder, Spirit and Opportunity were built to explore Mars, take pictures and collect samples with two, six-wheeled rovers. But while the Pathfinder could go distances of only a few meters, Spirit and Opportunity could go thousands. In April 2004, the Spirit and Opportunity rovers were dropped onto opposite sides of Mars and have been roving in and out of bedrocks and impact craters ever since.
