Scientists and mission planners are investigating how long-term space travel affects the human mind and body, as they work to get astronauts ready to make the big leap to Mars.

The mental aspects — the feelings of loneliness, isolation and solitude that could come with a multiyear space mission — are increasingly coming under the microscope, as an award-winning new documentary shows.

That film, "Space: The Longest Goodbye," delves into the complexities of cerebral concerns to carve a pathway toward identifying and treating long-term mental health issues in space as they relate to the deprivation of normal human contact.

Directed by Ido Mizrahy and featuring Dr. Al Holland, Kayla Barron, Dr. Jack Stuster, Cady Coleman, Sukjin Han, and Jackie Morie, this 87-minute film screened at last year's Sundance Film Festival. It's now scheduled for a limited theatrical release and an extended stay on Amazon's Prime Video and Apple TV+ streaming platforms beginning March 8, 2024.

Here's the official synopsis:

"In the next decade, NASA will send astronauts to Mars for the first time. Separated from Earth, and unable to communicate with ground in real time, crew members will experience extreme isolation that could gravely affect their three-year journey. This Sundance-premiering documentary follows a savvy NASA psychologist tasked with protecting daring space explorers."
