Review of Literature

Space exploration eventually breaks down to the advancement of engineering, astronomical observation, and physics. Some useful sources have been the scholarly works of  Narendra Bhandari, Malcolm Fridlund, and Kumar Krishen. They have provided distinct points of view from different aspects behind the challenges of space exploration. Approaches such as legitimacy, necessity, possibility and probability, safety, and technology. Many scholars believe that further space exploration is closer to our grips than believed, however on the other side of the spectrum, many believe that while we may soon have the ability to explore and/or colonize, it may be unsafe or impractical. Some scholars are more skeptical than others, but most believe that if we have the technology, and a suitable condition for humans to survive, we should, and likely will explore and colonize other planets.
