Scientists may soon uncover evidence of ancient life on Mars using a new laser instrument developed by the University of Bern. The device, called Laser Ablation Ionization Mass Spectrometry (LIMS), can zap samples from the Red Planet’s surface to detect signs of microfossils.
The odds of finding life on Mars have increased over the years as more robotic spacecraft explore the planet. However, scientists believe that any life on Mars would likely be simple and microbial, such as bacteria. This is due to the harsh conditions on the planet, including extreme dryness and radiation.
Researchers found evidence of fossil filaments in Martian gypsum deposits using the LIMS instrument. This discovery could provide a new lead in searching for signs of life on Mars. The team hopes to install similar instruments on future Mars missions to search for fossils within Martian gypsum deposits.
The discovery highlights the need for further exploration of Mars, particularly beneath its surface. Dr. Youcef Sellam from the University of Bern stated that these deposits can preserve fossil microorganisms and are promising targets for astrobiological research.
