Here on Earth, life finds a way in some of our most extreme and unlikely environments, so it's possible that microbial life may have once eked a living on our neighboring red planet, too.

found it would take 2 meters of ground to protect these molecules for about 80 million years - if we're lucky. Yet Mars has been inhospitable to life as we know it for billions of years now, meaning that any trace of it would have disintegrated beyond our reach.could survive much longer than previous estimates. This bacteria was so impressively robust the team nicknamed it Conan the Bacteria.
Based on their data, the team posits that Conan the Bacteria could survive 1.5 million years under a mere 10 centimeters of Mars dirt, and a whopping 280 million years if it were huddled 10 meters under the surface.buried in the Martian subsurface could not survive dormant for the estimated 2 to 2.
"This could complicate scientific efforts to look for Martian life. Likewise, if microbes evolved on Mars, they could be capable of surviving until present day. That means returning Mars samples could contaminate Earth.", that future rovers may be able to reach some traces of ancient microbial Mars life. That is, of course, assuming that such life was similar enough to that which we are familiar with, if it ever even existed at all.

Lucy Zipped Past Earth to get a Gravitational Assist Towards Jupiter's TrojansGravitational assists are marvels of orbital mechanics. Usually, they are done for a combination of fuel (i.e., cost) savings and speed, as it is sometimes faster to take multiple trips around planets in the inner solar system to reach locations in the outer solar system more quickly. Lucy recently made such a maneuver on its … Continue reading 'Lucy Zipped Past Earth to get a Gravitational Assist Towards Jupiter’s Trojans'
