Which of the following is NOT a common use for satellites in space?

• A. Communication
• B. Space mining
• C. Weather monitoring
• D. Earth observation

Answer: (B)

Satellites are built to perform tasks that can be done from orbit and rely on instruments that sense, relay, or image from space. The most common uses are relaying communications signals, which keeps TV, phone, and internet connections moving across great distances; monitoring weather, where instruments on weather satellites measure atmospheric conditions to help forecast storms and track climate patterns; and observing Earth, where high-resolution imagery and data support mapping, agriculture, and environmental management. Space mining stands out as not being a typical satellite task because extracting minerals would require landing machinery on another body, performing drilling and processing, and then returning materials to use here or in space. That kind of operation involves vastly higher costs, more complex robotics, and greater energy needs than standard satellite missions, so it isn’t a routine function today.
