Ep 1. Can We Make It to Mars?

In the first episode of NOVA scienceNOW season 5, titled "Can We Make It to Mars?", host Neil deGrasse Tyson leads viewers on a journey through the complexities of space travel and the challenges of sending humans to the red planet.

The episode begins by exploring the history of Mars exploration, from the first telescopic observations of the planet in the 17th century to the recent successful landing of NASA's Perseverance Mars rover. Tyson explains that the ultimate goal of many scientists and explorers is to send humans to Mars, and he outlines the various challenges that must be overcome to make this a reality.

One of the biggest obstacles is the long duration of the journey from Earth to Mars, which can take several months. The episode looks at how scientists are developing new propulsion systems to speed up the journey, as well as ways to protect astronauts from the harmful radiation they would encounter during the trip.

Once on Mars, astronauts would face a whole new set of challenges, such as how to survive in an inhospitable environment with no breathable air and extreme temperature swings. The episode talks to scientists who are developing new technologies to overcome these challenges, such as systems to generate oxygen from the Martian atmosphere and innovative spacesuits that can protect astronauts from the harsh conditions.

Tyson also explores the question of whether Mars was once a habitable planet, and the possibility of finding evidence of life on the planet. The episode visits the Mars Desert Research Station in Utah, where scientists simulate living and working on Mars to gain a better understanding of the challenges that would face future explorers.

Throughout the episode, Tyson highlights the importance of continued investment in space exploration and research, and the potential benefits that could come from sending humans to Mars. He argues that such a mission would inspire the next generation of scientists and engineers, and could lead to breakthroughs in technology and new discoveries about the origins of life in our solar system.

Overall, "Can We Make It to Mars?" is an engaging and informative look at the possibilities and challenges of human exploration of Mars. Tyson's enthusiasm and expertise make for a compelling viewing experience, and the episode provides a fascinating insight into the cutting-edge science and technology that is driving the quest to reach the red planet.
