Why humanity needs space

“Why do we need space when there are so many problems on Earth?” is a fair question, and it deserves an honest answer rather than pathos about the stars.

The first answer is down to earth: almost everything space does comes back to Earth. Satellites mean weather forecasts, communication, navigation, watching over harvests and fires. Technologies born for orbit have long lived in hospitals and phones. Space is not an escape from earthly tasks but a tool for solving them.

The second answer reaches past the horizon. History shows that civilizations which stopped exploring began to fade. A distant goal is not a luxury but a way to keep a society in shape and to set tasks that force it to learn. Besides, keeping all your eggs in one basket is a poor strategy for a species living on a single planet.

My opinion: space is worth it not because it is beautiful, but because looking upward changes the scale of thinking. From orbit the borders people fight over are simply invisible — and that may be the most useful lesson space can teach us.
