Can future astronauts be put into comas for space travel like in Project Hail Mary?

In the movie “Project Hail Mary,” Ryan Gosling plays Ryland Grace, a middle school science teacher who wakes up on a spaceship far from Earth. His mission is to save the sun from dying. The film, based on Andy Weir’s novel, uses real science, like the depiction of stars and artificial gravity, but also includes fictional elements like sun-eating microbes. The concept of putting someone in a coma for space travel is explored, but experts say it’s challenging due to metabolic needs and drug toxicity. However, a state called “synthetic torpor,” similar to hibernation in animals, could be possible for humans. This state could reduce metabolic demands and protect against space radiation, which is a major challenge for space exploration. QUESTION: How might the ability to induce human hibernation for space travel change the future of space exploration and our understanding of human biology?
