Asteroid Strikes: The Aftermath of a Near-Miss and the Need for Continuous Planetary Defense Strategies

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, is colliding with Earth. 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 in near-Earth space, with about 15,000 still remaining to be discovered.

One proposed method to prevent asteroids from impacting Earth is by altering their course 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 demonstrated the effectiveness of this approach.

After the collision, scientists observed a swarm of boulders surrounding Dimorphos. However, these boulders posed no threat to Earth and instead will 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.

The 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 highlighted the importance of developing strategies to protect Earth from future asteroid threats.

In conclusion, while we have seen successful results from altering an asteroid’s course using spacecraft collisions as demonstrated by DART (Double Asteroid Redirection Test), more needs to be done to protect our planet from future threats. The research findings highlight that even after successful deflection missions like DART some debris may still pose significant risks and thus require monitoring and further analysis for protection purposes.
