WHAT IS THE EFFICIENCY OF CURRENT AEROSPACE TECHNOLOGIES IN DETECTION AND DEFLECTION OF POTENTIALLY HAZARDOUS ASTEROIDS?

The growing realisation of the potential for an asteroid impact has led to a focus on whether current aerospace technologies are sufficient when it comes to detecting PHAs and attempting to deflect them. This paper explores the extent to which current space-based and ground-based telescopes, as well as the deflection strategies, are adequate means for defending against asteroids. A comprehensive review of detection capabilities highlights both the strengths and limitations of current detection and deflection techniques. Substantial progress has been made to advance this knowledge, particularly with missions such as NASA's DART, but current technology is inadequate ensuring that every asteroid threat can be addressed reliably and in a warning time frame. The paper concludes by identifying critical areas for enhanced deflection methods, to ensure a more robust planetary defence system in the future.
