What are natural threats to space systems?

• A. Ground-based jamming and cyberattacks
• B. Weather disturbances and atmospheric drag
• C. Solar radiation and orbital debris
• D. Micro-meteoroid impacts

Answer: (C)

The main idea is to recognize hazards that come from the space environment itself. Natural threats to space systems include the space radiation environment and the debris environment in orbit. Solar radiation, from the Sun and its storms, exposes spacecraft to charged particles and high-energy photons. This can cause radiation damage to electronics, single-event upsets, sensor noise, and degradation of solar panels. It’s a natural, recurring challenge whenever hardware operates in space, so designing systems to tolerate or mitigate those effects is essential. Orbital debris represents the clutter in space created by past missions and fragmentation events. High-speed collisions with even small fragments can inflict serious damage or disable a spacecraft. While some debris is human-made, its presence and the collision risk it creates are intrinsic to operating in orbital space, making it a fundamental environmental threat that missions must plan for. Together, solar radiation and orbital debris cover the two broad natural hazards space systems contend with: the space-weather–driven environment and the particulate debris environment. Ground-based jamming and cyberattacks are human-caused or ground-related threats, and weather or atmospheric drag pertains to Earth’s atmosphere rather than the space environment itself, while micro-meteoroid impacts are another natural hazard that isn’t the focus of this pair in this context.
