Viking 1 Mission
The Viking 1 was the first spacecraft to land on Mars successfully. The Viking 1 was composed of two main parts. The Lander which aloud it to land and study Mars's surface and the Orbiter which aloud it to orbit Mars's looking for a safe place to land and to take pictures from above.
Viking 1 Landing
On July 20, 1976 the Lander detached from the Orbiter and started its decent to Mars at 100,000 mph. To slow down the spacecraft so it can have a safe landing they had to use a parachute, rockets, and a aeroshell.

Viking 2 Mission
The Viking 2 was the second successful spacecraft to go to Mars. When the Viking 2 came back to Earth with test samples to see if there is any sign of aliens or the "unknown" on Mars. One test, the LR test came positive which means there could be life, but the control tests came back negative. Which gives us a clue if there is really life on Mars. Another thing about the Viking 2 is that there was no difference between the Viking 1 and 2, they both had the same parts and was used for the same goal, to see if there was life on Mars.
For the Future and Beyond
In the future Nasa is working on sending humans to Mars. For right now the have sent the Odyssey which is a spacecraft used to take pictures of Mars.
