Finding Alien Fossils Is NASA's Goal on Mars, says Astrobiologist

NASA Astrobiologist Dr. Svetlana Shkolyar Hopes The Mars Perseverance
Rover Captures Evidence of "Dead Stuff in Rocks."

NASA's Perseverance rover will collect and store soil samples that
could contain fossils and evidence of alien life. Though the mission
is just beginning, astrobiologists on Earth have been preparing for
this moment for over a decade.

Ever since NASA's Mars Viking landers returned the first controversial
hints of life on the red planet in the 1970s, astrobiologists have
dreamed of examining a sample of Martian soil up close.

Fortunately, since nearly all of the missions since Viking have helped
establish that Mars was once habitable, future mission planners could
zero in on the best places to search for signs of that ancient life.

Expected to land on Thu, Feb 18th, NASA's Perseverance rover
will study one of those areas up close. An ancient lake bed named
Jezero Crater. The rover will stash some of the most promising samples
for a possible return mission in the future. That mission is still on
the drawing board and at least a decade away, but if Perseverance
successfully collects and stores these soil samples, NASA will be
ready when those samples, and possible fossils, eventually return to
Earth.

It's obvious, there is a race between the United States and China to be
the first to find some extraterrestrial life. In the same way that there
was a race between the United States and USSR to be the first to walk
on the Moon
