The intricate mechanisms of the most sophisticated laboratory on Mars are revealed in Episode 4 of the ExoMars Rosalind Franklin series, called “Sample processing.” 

The Rosalind Franklin rover’s drill has a maximum reach of two metres – deeper than any other mission has ever attempted on the Red Planet. This depth allows access to well-preserved organic material from four billion years ago, when conditions on the surface of Mars were more like those on infant Earth. 

After receiving a sample from the drill, Rosalind’s laboratory must prepare the sample to make a detailed study of its mineral and chemical composition. The rover’s Analytical Laboratory Drawer (ALD) mechanisms execute a pre-programmed choreography of sample manipulations to make sure that the instruments can do their job.   

The ExoMars Rosalind Franklin mission is part of Europe’s ambitious exploration journey to search for past and present signs of life on Mars.
