Asteroids In 'Dune': A Review Of Space Obstacles And Hazards

Introduction

The world of science fiction has always been fascinated with the idea of space travel and exploration. In particular, the dangers and obstacles that astronauts face while traveling through space have been explored in many different stories and movies. One popular example is Frank Herbert's science fiction novel, 'Dune'. The book revolves around characters who travel through space and come across various obstacles, including asteroids. This article will review how asteroids are portrayed in 'Dune' and explore the reality behind these fictional portrayals.

The Role of Asteroids in 'Dune'

The Use of Asteroids as a Resource

In 'Dune', the asteroids are not just empty space objects. They are used as resources for the people living in space. The Belters, who are a group of people living in the asteroid belt, mine the asteroids for minerals and other resources. This concept is not entirely fictional. There are plans to mine asteroids in real life for the same purpose. The asteroids contain valuable resources such as iron, nickel, water, and platinum group metals. Mining these asteroids could help solve our resource shortage issues on Earth.

Asteroids as a Hazard in Space

The world of 'Dune' also portrays asteroids as a hazard in space. In the book, spaceships travel through space at a high velocity, making it difficult to dodge the asteroids. There is always a risk of colliding with an asteroid, which can cause catastrophic damage. Again, this concept is not entirely fictional. NASA tracks asteroids that could potentially collide with Earth and cause significant damage. In 2013, a meteor exploded over Chelyabinsk, causing damage to buildings and injuring over 1,000 people. This event shows how dangerous asteroids can be if they collide with the Earth.

The Reality of Asteroids as a Space Obstacle

Asteroid Detection and Tracking

Asteroids are not something to be trifled with, hence why NASA has set up detection and tracking mechanisms for near-Earth objects (NEOs). The agency's goal is to track 90% of NEOs that are 140 meters or larger. This mechanism will enable researchers to have enough time to prepare in case an asteroid trajectory could pose a severe danger. One example of an asteroid that flew past Earth recently is Asteroid 2021 KT1. It was estimated to be around 70-160 meters in size and flew past Earth on June 1st, 2021, at a range of approximately 4.5 million kilometers, which is roughly 11.7 times the distance between the Moon and Earth.

Asteroid Mining

Although the idea of mining asteroids is still in its infancy, there is already significant interest from entrepreneurs such as Elon Musk and Jeff Bezos. These entrepreneurs believe that mining asteroids for resources can help sustain human life beyond Earth and mitigate the limited resources we have on Earth. There are several companies such as Planetary Resources and Deep Space Industries that are planning to mine asteroids in the future. The asteroid '16 Psyche', for example, has been identified as an asteroid that could contain large amounts of valuable metals such as iron, nickel, and gold. According to NASA, the asteroid could contain $10,000 quadrillion worth of minerals, which is significantly more than the entire world's economy.

Conclusion

To conclude, 'Dune' offers an exciting take on the role of asteroids in space travel and exploration. Although the book is purely fictional, it does raise some interesting concepts about asteroids that are based on reality. Asteroids are not just empty space objects; they contain valuable resources that could help solve resource shortages on Earth. However, asteroids also pose a significant danger in space travel and exploration. It is, therefore, crucial to continue researching and developing technologies that will enable us to detect and track these asteroids and prepare better measures to prevent them from colliding with the Earth. Maybe one day, we will be able to utilize the resources of asteroids to sustain human life beyond Earth.
