Science Problems with Project Hail Mary Project Hail Mary is an ambitious effort to send an astronaut to Kepler 452b, a star system about 1,400 light years from Earth.
The primary goal is to determine whether there's life on this exoplanet and gather data that could shed light on the origins of life in the universe.
The science behind Project Hail Mary is rooted in panspermia, which suggests that life on Earth originated elsewhere in the universe.
