The 2019 sci-fi film “Ad Astra” is a thought-provoking and visually stunning movie that explores the possibilities of space travel and the search for extraterrestrial life. However, as with any science fiction film, it’s natural to wonder how accurate the movie’s depiction of space travel and astronomy is. In this article, we’ll delve into the facts behind the film and explore what’s real, what’s not, and what’s still a topic of debate among scientists and experts.
Space Travel and Propulsion
One of the most striking aspects of “Ad Astra” is its portrayal of space travel. The film shows astronauts traveling to the outer reaches of the solar system, including the Moon, Mars, and even Neptune. While the film’s depiction of space travel is largely accurate, there are some creative liberties taken to enhance the storytelling.
For example, the film shows astronauts traveling to Mars in a relatively short period, which is currently not possible with our current technology. According to NASA, a trip to Mars could take anywhere from 6 to 9 months using current propulsion systems. However, there are ongoing efforts to develop more advanced propulsion systems, such as nuclear propulsion and advanced ion engines, that could potentially reduce travel times.
The Moon and Mars Colonies
The film depicts a thriving colony on the Moon and a smaller outpost on Mars. While there are currently no human colonies on either the Moon or Mars, there are plans to establish a sustainable presence on the Moon in the near future. NASA’s Artemis program, for example, aims to return humans to the Moon by 2024 and establish a sustainable presence on the lunar surface by the 2020s.
As for Mars, there are several ongoing and planned missions to explore the planet and potentially establish a human settlement. NASA’s Curiosity rover has been exploring Mars since 2012, and the agency plans to launch a new rover, the Perseverance, in 2022. Private companies, such as SpaceX and Blue Origin, are also working towards establishing a human presence on Mars, with SpaceX aiming to send its first crewed mission to the planet in the mid-2020s.
The Search for Extraterrestrial Life
One of the central plot points of “Ad Astra” is the search for extraterrestrial life. The film shows a team of scientists searching for signs of life on other planets, including the moons of Jupiter and Neptune. While the search for extraterrestrial life is an ongoing area of research, the film’s depiction of the search is somewhat exaggerated.
In reality, the search for extraterrestrial life is a complex and challenging task that involves a range of scientific disciplines, from astronomy to biology. Scientists use a variety of methods to search for life, including studying the atmospheres of exoplanets, searching for biosignatures, and exploring the surfaces of other planets and moons.
The Magnetic Field of Neptune
One of the most memorable scenes in “Ad Astra” shows a massive storm brewing in the magnetic field of Neptune. While Neptune’s magnetic field is indeed a remarkable feature of the planet, the film’s depiction of the storm is somewhat inaccurate.
In reality, Neptune’s magnetic field is a complex and dynamic system that is powered by the planet’s internal heat budget. The field is so strong that it creates a region around Neptune known as the magnetosphere, which traps charged particles from the solar wind. However, the storm depicted in the film is not a realistic representation of the planet’s magnetic field.
The Psychological Effects of Space Travel
Finally, “Ad Astra” explores the psychological effects of space travel on the human mind. The film shows the main character, astronaut Roy McBride, struggling with the isolation and loneliness of space travel, as well as the emotional toll of searching for his lost father.
While the film’s portrayal of the psychological effects of space travel is somewhat exaggerated, it’s based on real concerns. NASA and other space agencies have been studying the effects of space travel on the human mind for decades, and there is growing evidence that long-term space travel can have significant psychological effects, including anxiety, depression, and cognitive impairment.
Conclusion
In conclusion, while “Ad Astra” takes some creative liberties with its depiction of space travel and astronomy, it’s a largely accurate and thought-provoking film that explores many of the real challenges and possibilities of space exploration. From the search for extraterrestrial life to the psychological effects of space travel, the film offers a compelling and realistic portrayal of what it might be like to travel to the outer reaches of our solar system.
Whether you’re a space enthusiast or simply a fan of science fiction, “Ad Astra” is a must-see film that will leave you pondering the wonders of the universe and the possibilities of human exploration. So the next time you gaze up at the stars, remember that the universe is full of mysteries waiting to be uncovered, and that the search for answers is just as much a part of the human experience as the search for life itself.
