Ep 3. Terror In Space

In NOVA season 26 episode 3, titled "Terror in Space," the show explores the dangers and challenges of long-term manned space flight.

With dreams of colonizing Mars and other planets, the prospect of sending humans on long missions into deep space has gained increasing interest and attention. However, as NOVA reveals, such journeys would pose many risks to the human body and mind.

The episode includes interviews with scientists who explain how the human body reacts to microgravity, cosmic radiation, and isolation. For example, zero gravity can cause significant bone and muscle loss and can even alter the structure of the brain. Additionally, space radiation can cause cellular damage and increase the risk of cancer.

To demonstrate these effects, NOVA follows three volunteers as they undergo a simulated 30-day mission to Mars. These volunteers live in a dome-like habitat in Hawaii, experiencing a range of difficulties including communication delays, food and water rationing, and sleep deprivation.

As the days go on, the volunteers begin to display signs of distress and fatigue, highlighting the emotional and psychological challenges of long-term space missions. NOVA also examines ways in which scientists are attempting to mitigate these effects, such as through exercise and medication.

Throughout the episode, NOVA raises critical questions about the ethics and sustainability of long-term manned space travel. While the prospect of exploring new worlds is exciting, it is important to consider the well-being of astronauts who undertake these missions. By shedding light on the challenges and risks involved, NOVA aims to stimulate important discussions about the future of space exploration.

Overall, "Terror in Space" is a fascinating and thought-provoking exploration of the impact of space travel on the human body and mind. Through interviews with experts and the simulation of a Mars mission, this episode offers valuable insight into the challenges and risks of long-term manned space missions.
