Mars Missions (in brief)



The Past (The Beginning) and The Future
The Mars Pathfinder mission was an important first step in rovers for NASA. The 1997 mission included the first successful rover on Mars, called Sojourner, which was delivered to the surface by the Pathfinder lander.
One of the mission's innovations was Pathfinder's landing system. Rather than using conventional rockets to touch down on the surface, NASA decided to use a cocoon of airbags instead. After going through the higher parts of the atmosphere, Pathfinder deployed a parachute and also shed the heat shield that protected the spacecraft from the heat that built up on the spacecraft during re-entry.
