A gigantic near-earth asteroid known as Apophis is set to pass by on April 13, 2029, and again in 2036, sparking concerns about the potential impact on Earth. This asteroid, with a diameter of 370 meters, is considered one of the most hazardous objects near our planet. The ISRO Chief, S Somnath, has emphasized the need for humanity to prepare for such catastrophic events and take proactive measures to safeguard Earth.
According to ISRO chief S Somnath, any asteroid larger than 10 km has the potential to cause an extinction-level event on Earth. He highlighted the frequency of such asteroid approaches towards planets and stressed the importance of developing technology to predict and deflect potential threats. The chief urged nations to work together on protocols for handling such situations and emphasized the significance of planetary defense.
ISRO has been actively involved in planetary defense initiatives, aiming to enhance technical capabilities and collaborate with global agencies in preparing for potential asteroid impacts. The chief emphasized the need for collective action, stating that the responsibility extends beyond India to the entire world. This collaborative approach is essential for developing the necessary programming capability and technical expertise to address asteroid threats.
On World Asteroid Day, ISRO hosted a workshop featuring experts from space agencies like JAXA and ESA, focusing on asteroid missions and planetary defense activities. The workshop aimed to raise awareness about asteroid impact threats and highlight the importance of coordinated efforts in mitigating such risks.
As Apophis continues to be closely monitored, astronomers have ruled out any impact risk for at least a century following recent radar observations. The precise orbit analysis has provided a clearer trajectory for the asteroid, eliminating concerns of a potential impact in 2068. The improved knowledge of Apophis’ position has bolstered confidence in its future movements and removed it from the risk list.
NASA’s successful DART mission in 2022, aimed at altering the trajectory of an asteroid, has inspired ISRO’s interest in participating in planetary defense missions. The ISRO chairman highlighted the significance of being prepared for potential asteroid threats and emphasized the importance of global collaboration in this critical endeavor.
While funding challenges remain a concern for ISRO, the agency is committed to leveraging its expertise in space missions to contribute to planetary defense efforts. With the impending close approach of Apophis in 2029, ISRO is gearing up to play a significant role in studying the asteroid and potentially participating in planetary defense strategies to safeguard Earth from potential impacts.
In conclusion, the looming threat of asteroid impacts underscores the importance of proactive preparedness and international collaboration in addressing planetary defense challenges. ISRO’s active involvement in planetary defense initiatives signals a collective effort towards safeguarding our planet against potential asteroid threats.
