Naked Science Season 6 Episode 7 Five Years on Mars
- December 17, 2009
Five Years on Mars is the seventh episode of the sixth season of the popular science documentary series Naked Science. The episode explores one of the greatest scientific achievements of our time: the successful landing and continual exploration of the planet Mars by NASA's Mars Exploration Rover mission, which marks its fifth year on the red planet.
The episode begins with the history of Mars exploration, from the earliest observations by ancient civilizations to early 20th century fiction and the first robotic explorations in the 1960s. We learn about the Viking missions, which landed two spacecraft on Mars in the 1970s, but ultimately failed to detect any sign of life. This led to a long hiatus in Mars exploration until the Pathfinder mission of 1996, which paved the way for the later Mars Exploration Rovers.
The episode then introduces us to the two rovers currently operating on Mars: Opportunity and Spirit, which have been on the planet since 2004. We learn about the challenges of designing and deploying a robotic mission on another planet, and the ingenious solutions that scientists and engineers have developed to make it happen. Through stunning footage and interviews with the scientists and engineers who work on the mission, we get a sense of the scale and complexity of the undertaking.
The majority of the episode is devoted to the science that the rovers have conducted over their five-year mission. We learn about the geological history of Mars, its topography, and the chemical composition of its rocks and soil. We see the breathtaking views that the rovers have captured of the Martian landscape, and learn about the insights they have provided into the possibility of past and present microbial life on the planet. We also learn about the ongoing search for evidence of water on Mars, which is seen as a necessary precursor to the possibility of finding life.
One of the most fascinating aspects of the episode is the way it shows the human element behind the mission. We meet some of the scientists and engineers who have devoted their lives to exploring Mars, and learn about the personal sacrifices they have made in order to do so. We also see the emotional reactions of the team when the Spirit rover becomes stuck in the sand and eventually ceases to communicate, highlighting the inherent risks and uncertainties of exploring another planet.
Throughout the episode, we are reminded of the broader significance of the Mars mission. This is not just about satisfying our curiosity about the universe, but also about advancing human knowledge and technology, and inspiring future generations to pursue careers in science and engineering. We see the public fascination with Mars exploration, and the impact that it has had on popular culture, as well as the practical applications that the mission has had, such as developing new materials and technologies for spaceflight.
Five Years on Mars is a compelling exploration of one of the greatest achievements of human exploration. It brings together stunning visuals, scientific expertise, and human drama to create a powerful celebration of the human spirit of curiosity and adventure. Whether you are a seasoned space enthusiast or just a casual viewer, this episode is sure to leave you awestruck and inspired.
