Mars Modules Edit
The Mars Science Lab, also known as the the Mars Robotic Analyzer is where samples from Mars Rovers are taken and studied. It consumes 2 samples a day for its research.
Make sure you send a few Mars Solar Power Modules first to provide power. These become Mars Solar Panels 1 when they land on Mars.
Long press on the Mars surface and wait for the "Land / Build" pop up, then "Land" your Science Lab next to a Solar Panel. It has to be next to a Solar Panel for power.
But what it does then hehe'_'
