What are the primary health risks associated with long-duration space travel, and how do these risks impact plans for future missions to the Moon and Mars?

This is primarily attributed to Spaceflight-Associated Neuro-ocular Syndrome (SANS), characterized by reduced eye stiffness, increased intraocular pressure, and other vision impairments.
