The Russian device, located on the side of the TGO (Trace Gas Orbiter) apparatus, did not find signs of life on Mars. He found no trace of phosphine, a gas that can be produced by microorganisms that do not need oxygen.

The ExoMars 2016 mission has not yet brought positive discoveries. Scientists from the Space Research Institute of the Russian Academy of Sciences (IKI RAS) hoped to find phosphine on the Red Planet, which is an important biomarker indicating the presence of microorganisms on the planet. It was recently found on Venus, but now the Russian device has been reconfigured to detect the same compounds on Mars. After spectral analysis in the infrared range, scientists stated that the planet does not have this gas. It is noted that the sensitivity of the equipment is high. It can detect 2 particles in 1 billion.
Nevertheless, scientists cannot yet assert the existence of the simplest organisms on Venus. This information requires additional study, for which it is necessary to send a probe to the planet. The most accurate biomarker is methane. It is with him that astronomers associate the probable presence of life on other objects in the solar system.
