ESA's 2030 Rover to Probe Martian Life Chirality

6/19/2026

Summary

Rosalind Franklin Analyzes

ESA will have the Rosalind Franklin rover analyze Martian soil in 2030.
The rover’s instrument, supplied by the Max Planck Society, will measure chirality of organic molecules to assess if they originated from living organisms.
Researchers applied the chirality-analysis method to two compounds in meteorite samples as a feasibility test.
The test showed meteorites can pick up trace fossil-fuel chemicals in Earth’s atmosphere, confirming the instrument’s sensitivity in detecting them.

Summary

NASA Halts Mars

NASA halted Mars sample-return program in June 2026 because funding shortfalls ended Earth analysis of Jezero Crater material.
ESA’s ExoMars rover, built by Max Planck Institute for Solar System Research, Universities of Göttingen and Côte d’Azur, was tested using 1969 Murchison meteorite.
The study identified pristane and phytane as Earth-derived contaminants and achieved chiral separation with Mars Organic Molecule Analyzer (MOMA), providing baseline for rover tests of biogenic vs abiotic signatures.

Summary

Scientists Trace Contamination

Scientists measured the Murchison meteorite and found equal chiral variants of pristane and phytane, unlike any known biomass.
The team concluded the equal-ratio contaminants were acquired during descent by contact with fossil-fuel combustion aerosols.
Co-author Manuel Reinhardt said petroleum formation in oil shales erases chiral imbalances over millions of years, explaining the composition.
The results prompt new questions on meteorite organics and warn of rising petroleum-derived contamination in Earth’s atmosphere.

History

Historical Context

Viking 1’s July 1976 landing gave the first Martian soil analysis, with its GC-MS reporting less than 10 ppb of organics and a positive Labeled-Release signal that remained disputed. Discovery of perchlorate by Phoenix in 2008 showed heating could destroy organics, prompting tighter contamination rules. ESA’s Rosalind Franklin rover now mirrors Viking’s approach, using the MOMA instrument to test chirality of pristane and phytane.
