Asteroid Deflection: A Groundbreaking Success in Preventing Earth’s Destruction but More Challenges Lie Ahead

NASA Successfully Collides Rocket into Asteroid, Potential Debris Threatens Mars

In the near future, a potential threat of an asteroid, similar in size to a football stadium, colliding with Earth looms. If it were to strike a city, the devastation would be comparable to that of a non-radioactive nuclear bomb. Currently, there are approximately 25,000 asteroids measuring around 460-feet long and about 15,000 still remaining to be discovered.

One proposed method to prevent asteroids from impacting Earth is to alter their course by colliding with them using a small spacecraft. In September 2022, a spacecraft the size of a van successfully deflected a 525-foot-long near-Earth asteroid named Dimorphos by crashing into it at 14,000 miles per hour. This groundbreaking planetary defense experiment, known as DART (Double Asteroid Redirection Test), demonstrated the effectiveness of this approach.

Following the collision, scientists observed a swarm of boulders surrounding Dimorphos but posed no threat to Earth. Ongoing analysis revealed that these boulders will not disintegrate in Earth’s atmosphere but will instead orbit the Sun for the next 20,000 years. Some of these boulders are projected to intersect with the orbit of Mars and potentially pierce through its atmosphere and create crater-like scars on its surface up to 1,000 feet in length.

Research findings published in a recent study by the European Space Agency’s Near-Earth Objects Coordination Centre shed light on the long-term implications of this mission and highlight the importance of developing strategies to protect Earth from future asteroid threats.

In conclusion, while we have witnessed an incredible success in preventing an asteroid from impacting Earth using small spacecraft collision technique in DART mission; we must continue to develop more advanced strategies as there are still many unknowns about potential future asteroid threats that may pose significant risks to our planet.
