The Reality of Asteroid Threats: Separating Fact from Fiction
The idea of an asteroid colliding with Earth has fueled countless movies and nightmares. But for Dr. Rajesh “Asteroid Hunter” Kapoor, a top astrophysicist at ISRO, this is more than fiction—it’s a real-world challenge he’s tackling daily.
With growing public concern over near-Earth objects (NEOs), we spoke to Dr. Kapoor to uncover the truth: Is Earth in imminent danger, and what’s being done to stop a potential disaster?
How Likely Is an Asteroid Impact?
Thousands of asteroids pass Earth yearly, most burning up harmlessly. But larger ones, like the 2013 Chelyabinsk meteor, remind us of their destructive power. NASA tracks over 25,000 NEOs, with 2,000 labeled “potentially hazardous.”
Dr. Kapoor, who leads ISRO’s NEO monitoring team, clarifies:
“The odds of a catastrophic strike in our lifetime are slim—but not zero. Early detection is everything.”
His team uses cutting-edge telescopes and AI to scan for threats, ensuring no asteroid slips through unnoticed.
The Scientist Behind the Mission
Dr. Kapoor’s passion for asteroid追踪 began at TIFR, where he studied celestial mechanics. Today, he collaborates with NASA and ESA to safeguard our planet.
“If we find an asteroid decades early, even a tiny nudge can divert it. But late detection limits our options,” he warns.
How Scientists Plan to Defend Earth
If a deadly asteroid heads our way, Dr. Kapoor explains three key strategies:
1. Deflection: NASA’s DART mission proved spacecraft can alter an asteroid’s path—ISRO is developing similar tech.
2. Disruption: Nuclear explosions in space could break smaller asteroids into harmless debris.
3. Evacuation: A last resort, but early warnings could save lives.
India’s Role in Global Planetary Defense
From the Astrosat telescope to upcoming NEO missions, India is a rising player in asteroid defense. Dr. Kapoor stresses:
“Asteroids don’t respect borders. Neither should our efforts to stop them.”
The Bottom Line: Should You Be Worried?
Good news: No major asteroid threats are predicted this century. Bad news? Thousands remain undiscovered.
Dr. Kapoor’s advice?
“Stay informed, not fearful. Science is advancing faster than ever.”
As our interview ended, he joked, “Tell Hollywood I’m too busy protecting Earth for a cameo.”
For now, experts like Dr. Kapoor—and their tireless sky scans—are our best defense.
