Government must spend a lot of money on exploring the space because it help us understand the hidden world inside galaxies, which might be the only boon to humanity after a certain period of time when all the dependence on material things and relevant sources vanish from the earth. For example, NASA, a space research centre have recently launched a satellite to study about the moon, where scientists landed on bare foot, found water source, and assured that it is one of the incredible place to resettle having the same climatic condition as that of earth, by spending multimillion dollars to figureout a safe place for humans after everything got vanished from our planet sooner or later.
