   Rosalind Franklin Rover Lab Separates Mirrored Organic Molecules

   The Mars Organic Molecule Analyzer on the Rosalind Franklin rover can distinguish between mirrored forms of phytane and pristane. This capability helps researchers rule out false positives in the search for ancient life. The rover is scheduled to analyze soil samples on Mars in 2030.

   What's confirmed:

   • The Mars Organic Molecule Analyzer on the Rosalind Franklin rover can distinguish between mirrored forms of pristane and phytane.
   • The Rosalind Franklin rover is scheduled to analyze soil samples on Mars in 2030.
   • Separating stable organic molecules is a step toward ruling out false positives on Mars.

   ESA Rover Instrument Successfully Distinguishes Mirrored Biosignatures

   The Mars Organic Molecule Analyzer on the Rosalind Franklin rover has proven it can distinguish between mirrored forms of pristane and phytane. These stable hydrocarbons are derived from biological sources on Earth and can persist for billions of years. The rover is scheduled to launch in 2030 to search for ancient life on Mars.

   What's confirmed:

   • The Rosalind Franklin rover is scheduled to launch in 2030.
   • The Mars Organic Molecule Analyzer can distinguish between mirrored forms of two stable hydrocarbons called pristane and phytane.
   • Pristane and phytane are molecules derived from chlorophyll and other biological sources on Earth.
   • The Rosalind Franklin rover is designed to search for molecules of life on Mars.
   • Researchers used the MOMA instrument to analyze chemical compounds in meteorite samples.

   Still unconfirmed:

   • A vast ocean once covered the landing site of the Rosalind Franklin rover.
   • Seven organic molecules never seen before on Mars were found inside a single rock, including one DNA precursor.
