NASA funds research into deep-sleep journey for Mars astronauts

The video discusses a NASA-funded concept where astronauts could hibernate during a long Mars mission. Sleep chambers equipped with cooling systems and nutrition tubes would lower body temperature and metabolism, inducing a torpor state. Muscle atrophy concerns are addressed with neuromuscular stimulation. As the spacecraft nears Mars, astronauts are gradually awakened, ready to begin their mission.

What methods do scientists propose to address muscle atrophy in astronauts?

Describe the process of waking up astronauts after their hibernation.
