Mars probes may never find life

Mars probes may never find life

Finding signs of life on Mars is one of the main reasons to send probes to the planet. But it is possible that the instruments sent to Mars so far are not sensitive enough for this. Because their technology is not even enough to find life on Earth. A team led by Armando Azua-Bustos of the Centro de Astrobiología in Madrid came to this surprising result based on experiments with terrestrial sediments that resemble Martian rocks. As reported by the working group in Nature Communications.She has found many signs of life in rocks from the Atacama Desert in Chile with the help of sensitive laboratory equipment. In contrast, results from instruments used on Mars today have remained close to or even below measurement limits — even if there are traces of life in the probe’s samples, the data is likely to remain murky at best.
