Key Facts About Space Debris

• Space debris refers to non-functional man-made objects in orbit.
• Includes defunct satellites, rocket stages, and collision fragments.
• NASA estimates 23,000 pieces of debris larger than a baseball.
• Over 500,000 marble-sized remnants exist.
• About 100 million fragments are over one millimeter.
• Debris burns up upon re-entry due to atmospheric drag.
• Kessler Syndrome describes a chain reaction of collisions increasing debris.
• International regulations like the Outer Space Treaty hold states accountable.
• The 1972 Convention imposes liability for damage caused by space objects.
• UN recommends satellites be deorbited within 25 years, with only 30% compliance.
• Global initiatives include ClearSpace-1 and Remove DEBRIS.
• India's initiatives include Debris Free Space Mission and NETRA.
• Recent crash in Kenya highlights space safety concerns.
• Large debris can destroy satellites; even small fragments pose risks.
• Most debris burns up, but large fragments can reach Earth.

Global Space Debris Management

The macro-level significance of space debris is profound, impacting global space exploration and satellite operations. Space debris poses a threat to the sustainability of space activities, which are crucial for communication, navigation, and earth observation. As India aims to expand its space capabilities, managing space debris aligns with its strategic goals of becoming a leading space-faring nation. Internationally, countries are ranked based on their space capabilities, and effective debris management is a key factor in maintaining these rankings.
