The Rosalind Franklin Rover: A Quest for Martian Biosignatures

The Rosalind Franklin rover, named after the pioneering British chemist and X-ray crystallographer whose work was crucial to understanding DNA, is the centerpiece of the ExoMars 2028 mission. Its primary scientific objective is to search for signs of past or present life on Mars. Unlike previous rovers that primarily focused on surface geology and the presence of water, Rosalind Franklin is equipped with a sophisticated drill capable of penetrating up to two meters (approximately 6.6 feet) beneath the Martian surface. This capability is critical because the surface of Mars is constantly bombarded by harsh ultraviolet radiation and cosmic rays, which would destroy organic molecules, or biosignatures, over time. By drilling deeper, the rover aims to access preserved samples that could contain evidence of microbial life that may have existed when Mars was warmer and wetter billions of years ago.

The rover’s scientific payload is a comprehensive suite of instruments designed for detailed geochemical and astrobiological analysis. Key instruments include:

• Mars Organic Molecule Analyzer (MOMA): This instrument, with significant contributions from NASA, is a state-of-the-art mass spectrometer. It will analyze the chemical composition of collected samples, specifically searching for complex organic molecules, which are the fundamental building blocks of life. Its capabilities extend to distinguishing between abiotic (non-biological) and biotic (biological) origins of detected organic compounds.
• Panoramic Camera (PanCam): Providing high-resolution 3D images of the Martian terrain, PanCam will aid in geological context and site selection for drilling.
• Infrared Spectrometer for ExoMars (ISEM): This instrument will identify minerals, especially those formed in the presence of water, offering insights into the past aqueous environments of Mars.
• Neutron Dosimetry for ExoMars (LiFE): Designed to measure radiation levels, helping assess the habitability potential for future human missions.
• Water Ice and Subsurface Deposit Observation on Mars (WISDOM) Radar: This ground-penetrating radar will map the subsurface structure, including potential layers of ice or water, up to several meters deep.

The chosen landing site for Rosalind Franklin is Oxia Planum, a region identified as rich in clay minerals. These minerals typically form in the presence of water and are known to preserve organic matter effectively, making it an ideal location for the rover’s life-hunting mission. The area also shows evidence of ancient river deltas and lakes, further increasing its astrobiological potential.
